Hospedagem barata com proteção DDoS (Junho 2026): 10 Fornecedores comparados - PT
Ataques DDoS atingidos 21.3 milhões por dia globalmente no quarto trimestre 2025, according to Cloudflare's threat report. O maior ataque registrado atingiu 31.4 Tbps. If you think your small business site isn't a target, considere isso: automated botnets don't discriminate by website size. They scan for vulnerable infrastructure and attack whatever they find. DDoS protection isn't optional anymore. The question is whether you need to pay extra for it.
Resposta rápida: You don't. Cloudflare offers free, unmetered DDoS protection backed by 477 Tbps of network capacity that you can layer in front of any host. For all-in-one hosting with built-in protection, OVHcloud includes 17 Tbps DDoS filtering on every plan starting at USD 1.04/mo. Budget buyers wanting managed shared hosting with DDoS should look at FastComet (US$ 1,79/mês, always-on ML-based filtering) ou HostArmada (US$ 1,99/mês, Imunify360). Abaixo, nós comparamos 10 provedores com abril verificado 2026 preços.

Última revisão: abril 2026. Preços e recursos verificados.
A maioria "DDoS-protected hosting" guides list providers without specifying what their protection actually covers. We verified mitigation capacities where published, distinguished between L3/L4 network-layer and L7 application-layer protection, and flagged providers whose "Proteção DDoS" amounts to basic IP null-routing that takes your site offline during an attack. We also dropped one commonly recommended provider (ScalaHosting) whose SShield tool handles malware, not DDoS.
Como selecionamos esses provedores
Selection required always-on DDoS protection included at no extra cost, with verified infrastructure details where available. We prioritized providers that publish mitigation capacities or name their DDoS technology partners (Cloudflare, OVHcloud, Hetzner/Nokia, A2 Hosting/Corero, Ultahost/BitNinja) over those making vague "protected" reivindicações. Pricing was confirmed against official sources in April 2026. Hosting types range from free CDN proxies to shared hosting, VPS, e servidores dedicados.

Ultahost: Highest Published DDoS Capacity for Budget Hosting
A partir de US$ 2,50/mês (compartilhado) | BitNinja, 3,500+ Gbps | Always-on | Preço fixo de renovação
Ultahost publishes the highest DDoS mitigation capacity of any budget hosting provider in this comparison: 3,500+ Gbps (3.5 Tbps) on their VPS and DDoS-protected VPS products. That's a concrete number backed by BitNinja's ML-powered defense system, which combines WAF protection, network monitoring, honeypots, and adaptive algorithms that learn new attack patterns. The system claims to filter 99% of known attack signatures.
All hosting types get BitNinja protection: compartilhado, VPS, servidores dedicados, e servidores de jogos. The shared Starter plan at USD 2.50/mo includes it alongside free SSL, backups diários, e armazenamento NVME. And here's what sets Ultahost apart from most competitors: os preços de renovação permanecem estáveis. What you pay on signup is what you pay next year. In a comparison where most providers double or triple their pricing at renewal, que a previsibilidade tem valor real.
The shared Starter plan limits you to 1 website and 30GB storage. Dedicated servers are capped at 150 Proteção DDoS em Gbps, lower than the VPS figure. Some user reviews note inconsistent support quality. o 3,500+ Gbps figure applies specifically to VPS products, not necessarily shared hosting (where BitNinja operates at the server level rather than the network edge). Contra FastComet, Ultahost wins on published capacity and renewal pricing stability, though FastComet includes more granular security features like CageFS isolation.
Prós
- 3,500+ Gbps published DDoS capacity (VPS)
- Preço fixo de renovação (sem salto de promoção para renovação)
- BitNinja WAF + malware scanning on all plans
- 99.99% garantia de tempo de atividade
Contras
- Shared Starter limited to 1 local na rede Internet, 30GB
- Dedicated server DDoS capped at 150 Gbps
- Some user reports of inconsistent support quality
Preços: Shared Starter at USD 2.50/mo (fixo, sem aumento de renovação). Basic at ~USD 3.80/mo. Business at ~USD 7.50/mo. DDoS-protected VPS from USD 4.80/mo. All include BitNinja DDoS protection. 30-day money-back on shared hosting.
Melhor para: Users wanting the highest documented DDoS capacity at budget hosting prices with predictable renewals.
Pular se: Você precisa de mais do que 1 website on the cheapest plan or want phone-based support.
Ultahost combines two rare things in budget hosting: a published DDoS capacity number and flat renewal pricing. Most competitors offer neither.

FastComet: Best Always-On ML Protection for Shared Hosting
A partir de US$ 1,79/mês | Machine learning-based | Always-on | All plans included
FastComet's DDoS protection runs machine learning algorithms trained on traffic patterns across their global network. The system identifies and blocks UDP floods, Inundações SYN, and HTTP floods inline, meaning malicious traffic gets filtered without routing to third-party scrubbing centers. That inline approach avoids the latency penalty that external mitigation adds during attacks. Protection covers all plans: compartilhado, VPS, e dedicado.
The Starter shared plan at USD 1.79/mo includes this protection alongside Imunify360 server security, um WAF, defesa de força bruta, verificação de malware, and account isolation via CageFS. Backups diários com 7-30 retenção diária (dependendo do plano) add another safety layer. The security stack is genuinely thorough for a host charging under USD 2/mo.
FastComet doesn't publish a specific Gbps or Tbps mitigation capacity. They claim the system "scales from personal blogs to large enterprises" but without numbers, that's marketing rather than specification. Preço de renovação salta de USD 1.79 para US$ 8,95/mês no plano Starter, aproximadamente um aumento de 5x. Comparado com HostArmada abaixo (preços semelhantes, Segurança Imunify360), FastComet's ML-based DDoS approach is technically different but neither provider publishes comparable capacity figures for shared hosting.
Prós
- Always-on ML-based DDoS protection em todos os planos
- Inline filtering (no third-party routing delay)
- Imunify360, WAF, verificação de malware, e backups diários incluídos
- 30-garantia de devolução do dinheiro em dia
Contras
- DDoS capacity não publicado
- A renovação salta para US$ 8,95/mês (5x preço de entrada)
- Entry plan storage limited to 15GB
Preços: Starter at USD 1.79/mo promo, USD 8.95 renovação. Essencial por US$ 2,39/mês, USD 11.95 renovação. Mais por US$ 3,59/mês, USD 17.95 renovação. Extra por US$ 4,99/mês, USD 24.95 renovação. Todos incluem proteção DDoS, Imunify360, backups diários.
Melhor para: Small business owners wanting full-stack security (DDoS + WAF + malware) at budget shared hosting prices.
Pular se: You need verifiable DDoS capacity numbers or predictable long-term pricing.
FastComet bundles more security features into their cheapest plan than most providers include on premium tiers. The DDoS protection is real, even if the capacity is unquantified.

HostArmada: Best VPS DDoS Capacity on a Budget
A partir de US$ 1,99/mês (compartilhado) | 17 Tbit/s VPS filtering | Imunify360 | 45-dia de devolução do dinheiro
HostArmada publishes a specific number for their VPS DDoS protection: 17 Tbit/s de capacidade de filtragem. That's the same figure OVHcloud claims for their entire global network, applied specifically to HostArmada's VPS infrastructure. For VPS users needing quantifiable DDoS protection at budget prices, this makes HostArmada's Spark plan (USD 3.69/mo annual) one of the best documented options available.
Shared hosting gets different protection. Instead of the 17 Tbit/s network filter, shared plans use Imunify360 with ModSecurity WAF, per-IP bandwidth throttling, SSL renegotiation protection, and reCAPTCHA challenges. It's effective against common attacks but lacks the published bandwidth capacity of the VPS line. The Start Dock shared plan at USD 1.99/mo includes this alongside daily backups, SSL grátis, e isolamento de conta. o 45-garantia de devolução do dinheiro em dia on shared hosting is the longest in this comparison.
The VPS money-back drops to just 7 dias. Shared hosting renewal doubles from USD 1.99 para US$ 9,95/mês. VPS renewal similarly doubles from USD 3.69 a US$ 8,20/mês. The reCAPTCHA challenge system on shared hosting can flag legitimate visitors, creating friction for real users during active attacks. Comparado com alojamento VPS geral opções, HostArmada's DDoS figures position their VPS competitively against providers costing 3-5x more.
Prós
- 17 Tbit/s published DDoS filtering on VPS plans
- Imunify360 security suite on shared hosting
- 45-dia de devolução do dinheiro em planos compartilhados (mais longo aqui)
- Backups diários incluídos em todos os planos
Contras
- 17 Tbit/s applies to Somente VPS, hospedagem não compartilhada
- Apenas reembolso de VPS 7 dias
- A renovação dobra para US$ 9,95/mês em compartilhado
Preços: Shared Start Dock at USD 1.99/mo promo, USD 9.95 renovação. VPS Spark at USD 3.69/mo annual (1 vCPU, 1GB, 40GB NVMe), renova ~USD 8,20/mês. VPS Flux at USD 5.18/mo (2 vCPU, 4GB, 80GB NVMe). Managed VPS Web Shuttle at USD 29.95/mo.
Melhor para: VPS users wanting published DDoS capacity figures at budget pricing.
Pular se: You need the same level of DDoS protection on shared hosting or want longer VPS trial periods.
HostArmada earns points for publishing actual numbers. In an industry where most hosts say "DDoS protected" without specifying what that means, 17 Tbit/s on VPS is a concrete, reivindicação verificável.
Cloudflare: Best Free DDoS Protection for Any Host
Plano gratuito disponível | 477 Tbps network capacity | L3/L4/L7 protection | 330+ PoPs globais
Cloudflare isn't a traditional hosting provider. It's a reverse proxy that sits between your visitors and your server, filtering traffic through 477 Tbps de capacidade de rede before it reaches your origin. Isso é 23 times larger than the biggest DDoS attack ever recorded. Cada plano, incluindo o nível gratuito, gets unmetered DDoS protection across L3, L4, and L7 layers. No traffic caps, no bandwidth limits on mitigation, no extra fees during an attack.
You can add Cloudflare to any existing host in about 10 minutes by changing your domain's nameservers. Your hosting provider doesn't need to support Cloudflare specifically. The free plan includes a basic WAF (Firewall de aplicativo da web), universal SSL, and always-on DDoS mitigation that handles most attacks automatically in under 3 segundos. The Pro plan at USD 20/mo adds enhanced WAF rules, and the Business plan at USD 200/mo includes 100 custom WAF rules plus PCI compliance.
A compensação: all traffic routes through Cloudflare's network, which adds a proxy hop. For most sites this actually improves performance (CDN caching), but it means Cloudflare sees your traffic. You also can't use Cloudflare's registrar without their nameservers. Support on the free plan is community-forum only. Cloudflare doesn't host your site, it only protects and accelerates it. You still need a separate hosting provider. Compared to OVHcloud's built-in protection below, Cloudflare requires more setup but provides dramatically larger mitigation capacity at zero cost.
Prós
- 477 Tbps rede, largest DDoS mitigation capacity available
- Free plan with unmetered L3/L4/L7 protection
- Funciona com qualquer provedor de hospedagem, no migration needed
- Mitigated a 31.4 Tbps attack no quarto trimestre 2025
Contras
- Not a hosting provider (protection layer only)
- Free plan support is community forum only
- All traffic routes through Cloudflare's network
Preços: Plano grátis: USD 0 (unmetered DDoS, basic WAF, SSL). Pró: US$ 20/mês (enhanced WAF, 20 custom rules). O negócio: US$ 200/mês (100 WAF rules, Conformidade com PCI). Empreendimento: preços personalizados. DDoS protection identical across all tiers.
Melhor para: Any website owner who wants enterprise-grade DDoS protection without changing hosts.
Pular se: You want all-in-one hosting + protection from a single provider.
Cloudflare is the answer to "I already have hosting but need DDoS protection." Point your DNS, esperar 10 minutos, and your site is behind the world's largest DDoS mitigation network. Livre.

Hostinger: Most Popular Budget Host with Tiered Protection
A partir de US$ 1,99/mês | Wanguard/RTBH filtering | Enhanced on Business+ | 30-dia de devolução do dinheiro
Hostinger includes basic DDoS protection on all hosting plans, but the implementation varies by tier. Entry shared plans get hardware firewall protection. The Business plan (US$ 2,99/mês) and above unlock enhanced features: Hostinger CDN and "Sob modo de ataque," which adds an extra verification layer during active attacks. VPS plans include Wanguard DDoS filtering on all tiers.
Two mitigation approaches work together. Traffic filtering through Wanguard targets malicious packets while preserving legitimate connections. For massive attacks that threaten to saturate network links, RTBH (Remotely Triggered Black Hole) routing kicks in. Hostinger has demonstrated handling attacks of approximately 8 Gbps and 1.5 million packets per second. The detection-to-mitigation window runs 20-50 segundos, which is honest but slower than providers claiming instant mitigation.
That RTBH fallback is worth understanding. During very large attacks, it null-routes your IP address, which stops the attack but also takes your site offline for all visitors temporarily. It's like stopping a fire by sealing the room. Effective but disruptive. Renewal on the Premium plan jumps from USD 1.99 para US$ 10,99/mês. No specific Tbps capacity is published. Contra HostArmada, Hostinger is cheaper at entry but offers less transparent DDoS specifications. Para a maioria orçamento alojamento partilhado casos de uso, the protection handles common attack patterns adequately.
Prós
- DDoS protection on all plans (enhanced on Business+)
- Demonstrated 8 Gbps attack handling capacity
- VPS includes Wanguard filtering at no extra cost
- 30-garantia de devolução do dinheiro em dia
Contras
- RTBH can take site offline during large attacks
- 20-50 segundo detection-to-mitigation lag
- Enhanced protection requires Plano de negócios (US$ 2,99/mês)
Preços: Premium Shared at USD 1.99/mo (48-mês), renova USD 10,99/mês. Business Shared at USD 2.99/mo (enhanced DDoS/CDN), renova USD 16,99/mês. KVM VPS 1 a US$ 4,99/mês (Wanguard included). 30-dia de devolução do dinheiro.
Melhor para: Beginners who want affordable hosting from a major provider with reasonable DDoS baseline protection.
Pular se: Your site can't tolerate any downtime during attacks or you need enterprise-grade mitigation.
Hostinger's DDoS protection works for the threat level most small websites actually face. Se você tem um blog pessoal ou um site de pequena empresa, the basic filtering catches common attacks. If you're running e-commerce or gaming servers, look at OVHcloud or layer Cloudflare on top.

OVHcloud: Best Infrastructure-Grade Protection Included
Starting at USD 1.04/mo (compartilhado) | 17 Tbps global filtering | L3/L4/L7 | All products included
OVHcloud bakes DDoS protection into every product they sell. Hospedagem Compartilhada, VPS, servidores dedicados, public cloud: all get the same always-on mitigation powered by their proprietary VAC (Vacuum) scrubbing system. The network handles sobre 17 Tbps of filtering capacity com até 1.3 Tbps per individual attack. No traffic limits, no time limits during attacks, no extra fees regardless of attack volume.
The VAC system combines an Edge Network Firewall with Armor scrubbing components. Traffic analysis happens at the network edge, filtering malicious packets before they reach your server. A Network Security Dashboard provides traffic monitoring and scrubbing logs with one-year retention. Para alojamento de servidor de jogos, OVHcloud offers an additional Game Shield layer purpose-built for gaming workloads that face targeted attacks.
OVHcloud shared hosting starts at just USD 1.04/mo for their Starter plan. VPS pricing begins at USD 6.46/mo with 4 vCores e 8 GB de RAM, which includes the same DDoS protection as their enterprise dedicated servers. A captura: everything is unmanaged. OVHcloud provides infrastructure, não de mãos dadas. Os tempos de resposta do suporte variam, and no money-back guarantee exists for North American customers (Os clientes da UE obtêm 14 dias por lei). Comparado com Cloudflare, OVHcloud 17 Tbps is smaller but it's genuine all-in-one hosting with DDoS, not a separate proxy layer.

Hetzner: Best European Value with AI-Powered Protection
Starting at ~USD 1.47/mo (compartilhado) | Nokia Deepfield Defender | Always-on | Data centers alemães
Hetzner deployed Nokia's Deepfield Defender across their European data centers in March 2026, upgrading from their previous Arbor/Juniper setup. The system uses AI and machine learning to detect attack patterns, with edge-based mitigation on Juniper routers that filters DDoS traffic before it enters the network. Complex application-layer attacks get redirected to Nokia's 7750 Defender Mitigation System for deep packet scrubbing.
Every Hetzner product gets this protection at no extra cost: Hospedagem Compartilhada, VPS em nuvem (from EUR 4.99/mo), e servidores dedicados. The shared Webhosting S plan starts at approximately USD 1.47/mo with no promotional-to-renewal price increase. That flat pricing model extends across all products. The DDoS system handles three layers: automated pattern recognition, traffic filtering for known attack signatures (DNS reflection, NTP reflection, Inundações UDP), and challenge-response filtering for SYN floods and DNS floods.
Hetzner doesn't publish their mitigation capacity, citing security policy. That means you can't compare their Tbps figures against OVHcloud or Cloudflare. Não existe garantia de devolução do dinheiro, though monthly billing with no long-term contracts limits your risk. Somente data centers europeus (Alemanha e Finlândia) para hospedagem compartilhada, so North American latency is a factor. Support runs on tickets only, no phone or chat. Comparado com OVHcloud, Hetzner offers similar flat pricing with arguably newer DDoS technology (Nokia AI vs OVHcloud's proprietary VAC), but without OVHcloud's published capacity figures.
Prós
- Nokia Deepfield Defender AI-powered detection (marcha 2026)
- Preço fixo, no promotional-to-renewal increases
- Edge-based mitigation filters traffic before entering the network
- ISO 27001 centros de dados certificados
Contras
- DDoS capacity não divulgado publicamente
- Somente data centers europeus (Alemanha, Finlândia)
- Sem garantia de devolução do dinheiro, suporte somente por ticket
Preços: Webhosting S at ~USD 1.47/mo (Preços em euros, taxa fixa). Cloud VPS CX23 at EUR 4.99/mo (2 vCPU, 4GB de RAM, 40GB SSD, 20Tráfego TB). Dedicated from EUR 47.30/mo. Todos incluem proteção DDoS. Sem preços promocionais, prices recently adjusted April 1, 2026.
Melhor para: European-focused sites wanting modern AI-powered DDoS protection at flat, preços honestos.
Pular se: You need North American servers or want published mitigation capacity numbers.
Hetzner's investment in Nokia's AI-powered defense signals they're taking DDoS seriously at the infrastructure level. The lack of published capacity figures is frustrating for comparison purposes, but the technology itself is cutting-edge.

IONIC: Most Affordable Entry with Split Protection
A partir de US$ 1/mês (promoção) | WebShield (L7 shared) + GSP (L3/L4 VPS) | 30-dia de devolução do dinheiro
IONOS takes an unusual approach: different DDoS technologies for different product types. Shared hosting gets WebShield, which protects the application layer (L7) against HTTP floods and similar attacks. VPS and dedicated servers get the Global Scrubbing Platform (GSP), handling network-layer (L3/L4) volumetric attacks. Both systems are always-on and included at no extra cost.
The USD 1/mo first-year promo on shared hosting makes IONOS the cheapest entry point with DDoS protection in this list. Renewal at USD 6/mo is also competitive. Cada cliente recebe um consultor pessoal dedicado, a unique touch that most budget hosts skip. Free Wildcard SSL covers all subdomains, e backups diários estão incluídos. VPS starts at USD 2/mo with GSP protection.
Neither system covers all layers by default. Shared hosting lacks L3/L4 network scrubbing (only L7 WebShield). VPS lacks L7 application protection (only L3/L4 GSP). Getting both layers requires adding Cloudflare or a separate CDN service. IONOS also explicitly states they "cannot guarantee 100% protection against all threats." Capacity figures aren't published. Renewal from USD 1 para US$ 6/mês is a 6x increase, though the absolute dollar amount remains low. Comparado com OVHcloud, IONOS provides cheaper entry pricing but less complete per-product DDoS coverage.
Prós
- USD 1/mês first-year promo, entrada mais barata aqui
- Consultor pessoal dedicado para cada conta
- Free Wildcard SSL (cobre todos os subdomínios)
- 30-garantia de devolução do dinheiro em dia
Contras
- Shared gets L7 only, VPS gets L3/L4 only
- No single product covers both network and application layers

Preços: Shared Start at USD 1/mo promo (12-mês), renova por US$ 6/mês. VPS Linux XS at USD 2/mo. All include respective DDoS protection tier. Domain Guard add-on USD 1-2.50/mo. 30-dia de devolução do dinheiro.
Melhor para: Budget buyers who want the absolute cheapest DDoS-protected hosting to start with.
Pular se: You need both L3/L4 and L7 protection from a single product.
IONOS delivers DDoS protection at prices other providers charge for unprotected hosting. The split-layer approach is a genuine limitation, but for most small websites facing basic attacks, WebShield on shared hosting handles the common threats.

Hospedagem A2 (Hospedagem.com): Best Hybrid Protection Architecture
A partir de US$ 2,99/mês | Corero SmartWall + cloud scrubbing | L3/L4/L7 | 30-dia de devolução do dinheiro
Hospedagem A2 (rebranded as Hosting.com in April 2025 após aquisição pelo World Host Group) uses a hybrid DDoS approach that combines on-premises and cloud mitigation. Corero SmartWall hardware sits at the network edge for immediate local filtering. When attacks threaten to overwhelm local capacity, traffic automatically redirects to multi-terabit cloud scrubbing centers. This two-tier system means small attacks get handled locally (mais rápido) while large attacks scale to cloud capacity (bigger).
Every A2 Hosting plan includes this protection: compartilhado, VPS, e dedicado. The Startup shared plan at USD 2.99/mo bundles it alongside Imunify360 for application-layer security, SSL grátis, e verificação de malware. o "Garantia de devolução do dinheiro a qualquer momento" provides a full refund within 30 days and prorated refunds after that. Turbo plans with LiteSpeed servers start at USD 6.99/mo for performance-focused sites.
Preço de renovação salta de USD 2.99 para US$ 10,99/mês no plano Startup. Specific on-premises Gbps capacity isn't published, only that cloud scrubbing reaches "multi-terabit" levels. The rebranding from A2 Hosting to Hosting.com may confuse users looking for the original brand. L7 protection relies on Imunify360 rather than dedicated application-layer scrubbing. Compared to OVHcloud's fully integrated approach, A2's hybrid model adds complexity but provides the flexibility of both local and cloud mitigation.
Prós
- Corero SmartWall on-premises + cloud scrubbing hybrid
- L3/L4 network filtering plus L7 via Imunify360
- Devolução do dinheiro a qualquer momento (rateado depois 30 dias)
- Protection on all hosting types
Contras
- Renovação em US$ 10,99/mês (3.7x preço de entrada)

Contabo: Best Specs with Basic DDoS Included
Starting at ~USD 4.95/mo (VPS) | Network-level filtering | Always-on | All plans included
Contabo includes DDoS protection on everything they sell: VPS, storage VPS, servidores virtuais dedicados, and bare metal. It's always-on, automatic, and costs nothing extra. For a provider whose primary appeal is cramming 4 vCPU and 8GB RAM into a USD 4.95/mo VPS, the DDoS inclusion is a practical bonus rather than a headline feature.
The protection works at the network level, automatically detecting attack patterns and filtering malicious traffic before it reaches your server. All Contabo plans include unlimited bandwidth (uso justo), so you don't face overage charges from attack traffic. The same protection covers their storage-focused VPS line and dedicated servers.
Contabo is honest about limitations. They explicitly state their "protection system cannot provide a guarantee that every conceivable DDoS attack will be repelled." No Gbps capacity is published. Community feedback suggests the protection handles common volumetric attacks but may fall short against sustained, sophisticated campaigns. No money-back guarantee is confirmed. Contabo não oferece hospedagem compartilhada tradicional, so their cheapest entry is VPS at ~USD 4.95/mo. For users whose primary need is raw server power and who want basic DDoS protection as a baseline, Contabo entrega. For users whose primary need is DDoS defense, providers like OVHcloud or Cloudflare offer stronger documented protection.

Preços: Cloud VPS S at ~USD 4.95/mo (EUR 4.50, 4 vCPU, 8GB de RAM, 75GB NVMe). Cloud VPS M at ~USD 7.60/mo (6 vCPU, 12GB, 100GB NVMe). All include always-on DDoS protection. Largura de banda ilimitada. Preço fixo.
Melhor para: Users who need high-spec VPS with basic DDoS protection as a baseline rather than a primary feature.
Pular se: DDoS protection is your top priority or you want published mitigation capacity.
Contabo's DDoS protection is a floor, not a ceiling. It catches common attacks. For anything beyond that, pair it with Cloudflare's free tier and you've got enterprise-grade protection on a USD 5/mo server.
How to Choose Hosting with DDoS Protection
Primeiro, understand the layers. L3/L4 protection stops volumetric floods (UDP, SYN, DNS amplification), the type of attacks that overwhelm bandwidth. L7 protection stops application-layer attacks (Inundações HTTP, Slowloris), which target your web server directly with seemingly legitimate requests. Idealmente, you want both. OVHcloud and Cloudflare cover all layers. IONOS splits them by product type. Most shared hosts cover L7 through WAFs and rely on upstream network filtering for L3/L4.
Check if capacity is published. OVHcloud (17 Tbps), Cloudflare (477 Tbps), HostArmada VPS (17 Tbit/s), e Ultahost (3,500+ Gbps) publish numbers. Hetzner, Hostinger, FastComet, and Contabo don't. Published numbers aren't a guarantee, but they signal that the provider has invested in quantifiable infrastructure rather than checking a marketing box.
Consider the Cloudflare combination strategy. Pair any cheap host (Contabo, Hetzner, OVHcloud) with Cloudflare's free plan and you get 477 Tbps of DDoS protection in front of your budget server. This is often the best value approach: buy hosting for specs and price, add Cloudflare for security. o melhor alojamento na nuvem providers generally include some DDoS protection, but combining with Cloudflare adds defense in depth.
Match protection to your risk profile. A personal blog faces different threats than an e-commerce store or a game server. Basic shared hosting DDoS handles script-kiddie attacks. Online stores handling payments need L7 protection at minimum. Gaming servers need both layers plus low-latency filtering. Scale your protection investment to your actual risk.
perguntas frequentes
What types of DDoS attacks does hosting protection cover?
DDoS attacks fall into three categories: volumetric (L3/L4), which flood your network bandwidth with massive traffic; ataques de protocolo (L3/L4), which exhaust server connection capacity through malformed packets; and application-layer attacks (L7), which target web server resources with seemingly legitimate HTTP requests. Most hosting providers cover L3/L4 through network-level filtering. L7 protection typically comes through WAFs (Firewalls de aplicativos da Web) like Imunify360, ModSegurança, or Cloudflare's WAF. OVHcloud and Cloudflare explicitly cover all three types. Budget shared hosts generally handle L3/L4 at the network level and L7 through application firewalls.
Is free DDoS protection enough for most websites?
For personal blogs, carteiras, e sites de pequenas empresas, sim. The DDoS protection included with providers like OVHcloud, Hetzner, FastComet, and Hostinger handles the automated attacks that make up the vast majority of DDoS incidents. Most attacks are under 1 Gbps and last less than 15 minutos. Free Cloudflare adds enterprise-grade defense on top of any host. You'd only need paid premium DDoS services if you're a specific target (political sites, plataformas de jogos, crypto exchanges) or handling sensitive financial transactions where even brief downtime has direct revenue impact.
Can I add Cloudflare DDoS protection to any hosting provider?
sim. Cloudflare works as a reverse proxy. You change your domain's nameservers to Cloudflare, and all traffic routes through their network before reaching your origin server. It works with shared hosting, VPS, servidores dedicados, and any provider that lets you control your DNS settings. A configuração leva cerca de 10 minutos. The free plan includes unmetered DDoS protection with no traffic limits. You can combine Cloudflare with any host in this list for layered defense, though pairing it with a host that already includes DDoS (like OVHcloud or Hetzner) creates redundant protection at the network level.
What happens to my site during a DDoS attack if I have protection?
With proper protection, legitimate visitors see no difference. Malicious traffic gets filtered at the network edge before reaching your server. Your site stays online and responsive. Without protection, or when attacks exceed your provider's capacity, your server becomes unreachable for everyone. Some hosts use RTBH (null-routing) during large attacks, which stops the attack by taking your IP offline entirely. Hostinger acknowledges using this approach for overwhelming attacks. OVHcloud and Cloudflare are designed to absorb attacks without null-routing, keeping your site accessible throughout. A diferença importa: filtered protection keeps you online, null-routing stops the attack but takes you down temporarily.
Veredicto Final
Here's the smartest approach for most users: pick your host based on price and features, então adicione Cloudflare free plan for 477 Tbps of DDoS protection. Feito. A Contabo VPS at USD 4.95/mo behind Cloudflare gives you enterprise-grade DDoS defense on a budget server.
For all-in-one hosting with strong built-in protection, OVHcloud lidera com 17 Tbps filtering from USD 1.04/mo. Hetzner matches with Nokia's AI-powered defense at flat pricing from ~USD 1.47/mo. Ambos não são gerenciados, so pair with FastComet (US$ 1,79/mês) ou HostArmada (US$ 1,99/mês) if you need managed shared hosting with included protection.
Ultahost stands out for publishing the highest capacity number (3,500+ Gbps) at budget prices with fixed renewals. Hospedagem A2 earns credibility through its named Corero SmartWall partnership. IONIC offers the cheapest entry at USD 1/mo, though its split-layer protection means no single product covers all attack types.
Pular Contabo if DDoS is your primary concern. Its protection is basic and openly acknowledged as limited. But if you want maximum specs and add Cloudflare free, it becomes one of the best protected setups per dollar.
