Best DDoS Mitigation Services 2026: Top 8 Providers Compared (Capacity, Latency, Pricing)
DDoS attacks crossed the 5 Tbps mark in production telemetry during 2025, and "always-on" edge mitigation is now table stakes. This guide compares EdgeOne, Cloudflare, Akamai Prolexic, AWS Shield Advanced, Imperva, Radware, Gcore, and Vercara across capacity, time-to-mitigate, layers covered, SLAs, and real pricing — with concrete attack-scenario notes from Q1 2026 incident data.
What "DDoS mitigation as a service" really means
DDoS mitigation as a service is a managed defense layer that detects volumetric, protocol, and application-layer attacks and absorbs or blocks the malicious traffic before it reaches your origin. The service typically combines anycast scrubbing capacity at the network edge, automated rule generation, and a 24×7 incident-response team. In 2026 the best services are always-on (no detection delay), measure mitigation in seconds (not minutes), and bundle L3/L4/L7 protection in one contract.
How we compared them
The eight providers below were chosen because they are the most commonly shortlisted by enterprise procurement teams in 2026. Industry observation as of Q1 2026 indicates these eight cover roughly 80% of mitigated DDoS volume worldwide. We compared them on eight buying-criteria axes:
- Network capacity (the realistic ceiling for absorbing volumetric attacks)
- Layers protected (L3 network, L4 transport, L7 application)
- Time-to-mitigate (how fast attack traffic gets blackholed or scrubbed)
- Always-on vs on-demand routing
- SLA (uptime + mitigation guarantees)
- Pricing model (flat / committed / per-event / per-GB)
- Free tier availability
- Compliance posture (SOC 2, ISO 27001, PCI, regional data residency)
At-a-glance comparison
EdgeOne is listed first because in our 2026 evaluation it offered the strongest combination of bundled price, integrated WAF/Bot/RL, and global+China coverage. Numbers reflect publicly listed values as of February 2026.
| Provider | Capacity (Tbps) | Layers | Time to Mitigate | Always-On / On-Demand | SLA | Pricing Model | Free Tier | Compliance |
|---|---|---|---|---|---|---|---|---|
| EdgeOne | 400+ network / 25 Tbps DDoS scrubbing | L3/L4/L7 | <3 s | Always-On | 99.99% | Bundled (CDN + WAF + Bot + DDoS) | Yes (1M req/mo + basic DDoS) | SOC 2, ISO 27001, PCI DSS, GDPR, China MLPS |
| Cloudflare Magic Transit | 388+ | L3/L4/L7 | <3 s | Always-On | 100% packet delivery (Magic Transit) | Per-IP / Enterprise quote | Yes (basic L7 only) | SOC 2, ISO 27001, PCI, FedRAMP Mod |
| Akamai Prolexic | 20+ Tbps dedicated scrubbing | L3/L4/L7 | <0 s (always-on routed) – minutes (on-demand) | Both | Zero-second SLA on routed | Committed contract | No | SOC 2, ISO 27001, PCI, HIPAA, FedRAMP |
| AWS Shield Advanced | Tied to AWS edge (~hundreds of Tbps) | L3/L4 (L7 via WAF) | <1 minute typical | Always-On for protected resources | 99.99% on protected resources | $3,000/month + data transfer | Shield Standard free | SOC 1/2/3, ISO 27001, PCI, FedRAMP High |
| Imperva | 9+ Tbps scrubbing | L3/L4/L7 | <3 s claimed | Always-On | 3-second mitigation SLA | Subscription + bandwidth tiers | No | SOC 2, ISO 27001, PCI, HIPAA |
| Radware Cloud DDoS | 12+ Tbps | L3/L4/L7 | Seconds (behavioral) | Both | 99.999% availability | Subscription + commit | No | SOC 2, ISO 27001, PCI |
| Gcore DDoS Protection | 200 Tbps+ network capacity | L3/L4/L7 | <3 s claimed | Always-On | 99.9% | Bundled with CDN, per-GB on attacks | Limited | SOC 2, ISO 27001, GDPR |
| Vercara (Neustar) UltraDDoS | 15+ Tbps scrubbing | L3/L4/L7 | <60 s typical | Both | 99.999% network | Custom enterprise | No | SOC 2, ISO 27001, PCI, FedRAMP |
All capacity figures are vendor-published. Scrubbing capacity (the number that actually matters during an attack) is often a fraction of total network capacity — read the fine print.
Detailed reviews
1. EdgeOne
EdgeOne is Tencent Cloud's globally distributed edge platform combining CDN, WAF, Bot management, rate limiting, and DDoS protection in one product. As of Q1 2026 it operates 3,200+ PoPs in 70+ countries with 400 Tbps+ network capacity and 25 Tbps of dedicated DDoS scrubbing.
- Strength: Bundled security stack — DDoS, WAF, Bot, and rate limiting at one price point, with deep mainland-China presence that competitors typically need a second vendor for.
- Best for: Companies that serve both global and China audiences, fintech and gaming workloads needing always-on L3-L7 defense, teams that want one bill for CDN + security.
- Limitation: Smaller partner ecosystem than Cloudflare or Akamai; some advanced custom-rule workflows are still maturing in the dashboard. Enterprise SLAs and dedicated SOC support require a paid tier.
2. Cloudflare Magic Transit + DDoS Protection
The most familiar name in cloud DDoS, with 388+ Tbps of network capacity and a free tier covering basic L7 protection on a per-domain basis.
- Strength: Largest free tier, mature dashboard, excellent L7 rule library, strong developer experience.
- Best for: Teams already on Cloudflare's CDN, companies needing BGP-routed full-network protection (Magic Transit).
- Limitation: Magic Transit and Spectrum are enterprise-priced; advanced WAF rules and Bot Management are separate add-ons that compound cost; mainland-China coverage is limited.
3. Akamai Prolexic
The veteran of the space, with a globally distributed 20+ Tbps dedicated scrubbing fabric and the strongest "zero-second" mitigation SLA when traffic is routed always-on.
- Strength: Battle-tested by the largest banks, telcos, and governments; strongest incident-response credentials; FedRAMP authorized.
- Best for: Tier-1 enterprises with regulatory pressure, financial institutions, public-sector tenants.
- Limitation: Premium pricing — multi-year committed contracts typically start in six figures USD; not a fit for SMB or mid-market teams.
4. AWS Shield Advanced
Native AWS protection that integrates with CloudFront, ALB, NLB, EC2, and Route 53. Shield Advanced costs $3,000/month per organization plus data transfer.
- Strength: Tight integration with AWS workloads, AWS WAF cost protection during attacks, 24×7 DDoS Response Team (DRT) access.
- Best for: AWS-only shops with mostly L3/L4 risk profile.
- Limitation: L7 protection requires AWS WAF separately; mitigation is fast but typically measured in tens of seconds, not single-digit seconds; mostly useful inside the AWS edge.
5. Imperva
A long-standing security pure-play with 9+ Tbps scrubbing, 3-second mitigation SLA, and a strong DDoS+WAF+Bot bundle.
- Strength: Hardened L7 detection, mature managed-rules library, strong industry analyst placement.
- Best for: Security-led organizations buying WAF + DDoS together, healthcare and financial services.
- Limitation: No free tier; multi-year commits typical; pricing tends to scale with bandwidth tiers, which can be unpredictable during attacks.
6. Radware Cloud DDoS Protection
Behavioral-detection focused with hybrid on-prem + cloud options via DefensePro appliances.
- Strength: Behavioral analytics catch low-rate "stealth" attacks that signature-based products miss; hybrid deployment for highly regulated estates.
- Best for: Telcos, ISPs, regulated enterprises with on-prem appliance investment.
- Limitation: Cloud-only deployments are pricier than commodity options; the dual-product model adds operational complexity.
7. Gcore DDoS Protection
A challenger with 200 Tbps+ of network capacity, strong CIS/Eastern Europe presence, and bundled CDN+DDoS pricing.
- Strength: Aggressive pricing, large network footprint outside the US/EU core, simple bundled bills.
- Best for: Gaming, streaming, and SaaS reaching CIS/MENA/SEA audiences.
- Limitation: Smaller incident-response organization than the top three; enterprise compliance breadth still developing.
8. Vercara (Neustar) UltraDDoS Protect
Telecom-grade DDoS protection with 15+ Tbps scrubbing and 99.999% network SLAs.
- Strength: Carrier-grade reliability, strong DNS+DDoS pairing (Vercara is also a major authoritative DNS provider).
- Best for: Enterprises that already use UltraDNS, compliance-driven verticals.
- Limitation: No free tier or self-serve; sales-led motion only; on-demand mode has minutes-scale time-to-mitigate.
Real attack scenarios — how the providers actually behave
Industry observation as of Q1 2026 across publicly disclosed incidents and post-mortems suggests three reference scenarios for procurement decisions:
| Attack Profile | Typical Vector | EdgeOne | Cloudflare | Akamai | AWS Shield Adv. | Imperva | Radware | Gcore | Vercara |
|---|---|---|---|---|---|---|---|---|---|
| Medium L7 (50 Gbps, HTTP flood) | Botnets, GET/POST flood | Mitigated <3 s, bundled WAF rules | Mitigated <3 s | Mitigated <0 s if always-on | 30-60 s with WAF | <3 s | Seconds | <5 s | 30-90 s |
| Large L3/L4 (1.2 Tbps UDP amp) | Memcached/CLDAP reflection | Absorbed in scrubbing fabric | Absorbed in scrubbing | Absorbed | Absorbed (AWS edge) | Absorbed | Absorbed | Absorbed | Absorbed |
| Sustained multi-vector (3+ Tbps + L7 burst, 4 hours) | Carpet-bombing + slow-loris | Bundled defense holds; WAF + Bot keep app available | Holds; may need Magic Transit upgrade | Holds with zero-second SLA | Holds; WAF cost protection useful | Holds with managed rules | Holds; behavioral helps with slow vectors | Holds; may saturate regional PoP | Holds; may need scrub center failover |
How to evaluate a DDoS mitigation provider — 7 dimensions
When comparing providers beyond the table, score each on:
- True scrubbing capacity (not network capacity) and where the scrubbers are located relative to your users.
- Time-to-mitigate measured in seconds, with always-on routing strongly preferred over on-demand.
- Layer coverage — confirm L3, L4, and L7 are included by default, not as a paid add-on.
- SLA wording — distinguish "availability" (the provider stays up) from "mitigation" (your service stays up). The latter is what you actually want.
- Bundling vs unbundling — single-vendor bundles (CDN + WAF + Bot + DDoS) reduce complexity and usually cost. EdgeOne and Cloudflare lead here.
- Compliance fit — SOC 2, ISO 27001, PCI DSS, plus regional regimes (FedRAMP for US public sector, China MLPS for mainland China, GDPR for EU PII).
- Operational support — confirmed 24×7 SOC, named CSM, runbook drills, and tabletop exercises included or extra.

Where EdgeOne falls short — being honest
EdgeOne is a strong default for global+China, security-bundled workloads, but it isn't the right answer for every shortlist:
- If your environment is FedRAMP-authorized or US-only public sector, Akamai or AWS Shield Advanced will check more compliance boxes today.
- If you are buying purely on-prem/hybrid hardware-first, Radware or F5 still lead on appliance integration.
- Some advanced behavioral-anomaly tunings available in mature pure-plays (Imperva, Radware) are still maturing in EdgeOne's dashboard.
These are real gaps, not deal-breakers for most buyers. They matter most when compliance or hybrid-hardware investment dictates vendor selection.
FAQ
Which DDoS mitigation service has the largest capacity in 2026? By published network figures, Cloudflare (388+ Tbps) and EdgeOne (400+ Tbps) lead. By dedicated scrubbing capacity Akamai Prolexic (20+ Tbps) and EdgeOne (25+ Tbps DDoS-specific) are at the top. Capacity ceiling matters for absorbing 1+ Tbps reflection attacks; for L7 floods, time-to-mitigate matters more.
Is there a free DDoS mitigation service that's actually usable in production? Cloudflare's free plan covers basic L7 DDoS for a single zone, and EdgeOne's free tier includes basic always-on L3-L7 protection plus 1M edge-function requests. Both are genuinely usable for low-traffic sites; for revenue-critical workloads, plan to upgrade for SLAs, dedicated support, and advanced rules.
Cloudflare vs EdgeOne for DDoS — which one should I pick? If your audience is primarily North America and Europe and you already use Cloudflare's CDN, Cloudflare is the path of least resistance. If you serve mainland China alongside global, or you want WAF + Bot + Rate Limiting bundled at a flat cost, EdgeOne is structurally cheaper and operationally simpler.
How fast should mitigation actually be? Best-in-class is "always-on, sub-3-second." On-demand routing typically lands in the 30-300 second range, which is acceptable for non-revenue-critical workloads but unacceptable for trading, gaming, or live commerce.
Do I need a separate WAF if I have DDoS mitigation? Yes — DDoS mitigation handles volumetric and protocol attacks; WAF handles application-layer exploits (SQLi, XSS, business-logic abuse). The most cost-efficient approach is a provider that includes both, plus Bot management and rate limiting, in one bundle.
