DDoS Stress Testing
Authorized L4 + L7 DDoS simulation against your real edge.
Simulate real-world Layer 4 (transport) and Layer 7 (application) DDoS attacks against your infrastructure under controlled, authorized conditions. We generate high volumes of malicious traffic to test resilience, then write a report comparing measured vs expected mitigation.

The problem
Your provider's dashboard says you're protected. Only a real attack proves it — so run the attack yourself, on your terms.
Mitigation configs drift silently
Every CDN swap, WAF ruleset change, and origin migration can reopen a hole in defenses that looked solid last quarter. Nothing warns you — until live attack traffic finds the gap during your worst possible hour.
Providers mark their own homework
Your DDoS vendor's 'we blocked X Tbps' stat measures their product on their terms — usually synthetic Layer 4 volumetrics. It says nothing about how your real edge, your rules, and your origin behave under a Layer 7 flood.
Layer 7 is where cheap attacks win
Volumetric defenses miss application-layer abuse: a few thousand well-crafted requests per second against expensive endpoints — search, login, checkout — can exhaust your origin while the bandwidth graph still looks calm.
The first real attack is a terrible time to learn
During a live incident you have no baseline, no abort switch, and revenue draining by the minute. A controlled test gives you the same data with a signed authorization, a kill switch, and your provider on standby.
Scope of work
What's included
Everything below is delivered by senior engineers — no scanner-only reports, no junior hand-offs.
- L4 attacks: volumetric, SYN flood, UDP flood
- L7 attacks: HTTP flood, slow-loris, application-logic abuse
- Customized test plan tailored to your stack
- Coordinated with your provider (Cloudflare, AWS Shield, Akamai)
- Real-time test dashboard recordings
- Post-mortem analysis vs expected mitigation
Methodology
How we run it
- 01Sign authorization agreement defining scope and objectives
- 02Coordinate with your provider and ISP
- 03Baseline metrics captured before the test
- 04Progressive ramp-up across multiple attack vectors
- 05Measure mitigation effectiveness at each tier
- 06Post-test debrief with metric comparison
Comparison
Why not just rely on your provider's stats?
| Feature | AnySec | Generic firm | DIY |
|---|---|---|---|
| Realistic attack patterns | Bot-realistic L7 + L4 volumetric | Synthetic L4 only — provider self-tests | Hard to source legally + safely |
| Coordination | We handle provider + ISP authorization | Provider tests their own product | Yours to figure out |
| Independence | Independent of your provider's incentives | Vendor-biased | Independent |

FAQ
Questions we get asked
What is DDoS stress testing?+
DDoS stress testing is an authorized, controlled simulation of a distributed denial-of-service attack against your own infrastructure. Engineers generate realistic Layer 4 (volumetric, SYN/UDP flood) and Layer 7 (HTTP flood, slow-loris, application-logic abuse) traffic to measure whether your CDN, WAF, and origin actually absorb it — then report measured mitigation against what your stack was expected to do. It is the only way to prove your DDoS defenses hold before a real attacker tests them for you.
Is DDoS stress testing legal?+
Yes — when it's authorized. We fire test traffic only after a signed authorization agreement defining scope, targets, and timing, and we coordinate advance notice with your hosting provider and ISP, most of whom contractually require it for synthetic load. Unauthorized DDoS traffic, by contrast, is a criminal offense across the EU and most jurisdictions — the signed scope is what separates a stress test from an attack.
Will this take down our production?+
Only if your mitigation is missing — which is the point. We start small and ramp up; we abort the moment your stack folds, so the impact window is minimized.
Do we need to notify our DDoS provider?+
Yes — and we will help coordinate with them. Most providers require advance authorization for synthetic load testing.
Can you test at our scale?+
We've delivered tests up to sustained multi-Tbps. For larger or unusual scopes, ask on the discovery call.
How often should we run a DDoS stress test?+
Twice a year at minimum, and after any change to your edge stack — new CDN, new WAF ruleset, new origin architecture. Mitigation configs drift silently; a stress test is the only way to catch a gap before an attacker does.
How is DDoS stress testing different from load testing?+
Load testing measures capacity under legitimate traffic — how many real users you can serve before latency climbs. DDoS stress testing measures resilience under hostile traffic — whether malicious L4/L7 patterns designed to exhaust resources can knock you over. Passing a load test tells you nothing about surviving an attack; the traffic shapes and failure modes are different.
How is this different from a penetration test?+
A penetration test looks for exploitable weaknesses in your applications and infrastructure. A DDoS stress test measures a different failure mode entirely — whether your stack stays up under volume. Many clients run both: see our penetration testing service for the exploit-focused half.
