DDactic is an automated DDoS resilience testing platform for security teams that already own a CDN/WAF (Cloudflare, Akamai, Imperva, AWS Shield, Radware) but have never validated whether their protection actually covers their full attack surface.
The platform discovers exposed assets, simulates Layer 3 through Layer 7 DDoS attacks from a fleet across 23+ cloud providers, and produces vendor-specific hardening recommendations validated by stage-reprobe after the customer applies them.
Free passive scan (no signup) maps subdomains, CDN/WAF detection, port profile, TLS fingerprint, breach correlations, and third-party SDK leaks. Paid active simulation runs ~200 attack vectors across L3 (volumetric), L4 (TCP/UDP/QUIC), L7 (HTTP, HTTP/2, HTTP/3), Low-and-Slow, Protocol-Specific (SMTP/SSH/RDP/SIP/LDAP/gRPC/WebSocket), and ATO replay when paired with breach data.
Built around the Open Protection Index (OPI), an Apache 2.0 open standard for grading external DDoS posture. Used by security teams that need an attacker-perspective check, not another paper questionnaire.

API
REST API for scan submission and report retrieval. Used for CI/CD integration.
Free Trial
Free passive scan tier, always-on, no signup required.
Open Source
OPI Score specification + reference implementation (Apache 2.0). Platform is proprietary.
Vendor Integration
Cloudflare, AWS Shield, Imperva, Akamai, Radware (read-only config validation + hardening playbook generation).
Bot Fleet Coverage
23+ cloud providers across 4 continents for distributed L3-L7 attack simulation.
Attack Vectors

Self-hosted
No. SaaS-only.
DDactic is the only platform that combines automated attack-surface discovery with multi-vector L3-L7 attack simulation from a fleet across 23+ cloud providers, and validates the customer's protection vendor configuration with stage-reprobe after each hardening change.
The Open Protection Index (OPI), Apache 2.0, gives customers a vendor-neutral 0-100 score they can benchmark over time. Most DDoS testing services run a single-vendor appointment-based simulation; DDactic runs continuous, multi-vendor, attacker-perspective testing.
Three reasons:
Real bot-detection bypass research, with 25 vendor fingerprints catalogued (PerimeterX, DataDome, Akamai BotManager, Cloudflare Challenge, etc.), so attacks are not blocked by trivial defenses and customers see what their CDN/WAF actually allows through.
Protection-group-aware testing that maps which subdomains share fate with which origin, exposing the shared-fate risk that most teams miss because they only think about their flagship asset.
Vendor-specific hardening playbooks (Cloudflare, AWS Shield, Imperva, Akamai, Radware) validated by stage-reprobe after the customer applies them, not generic recommendations from a paper questionnaire.
Security teams at companies that already pay for CDN/WAF protection (Cloudflare, Akamai, Imperva, AWS Shield, Radware) but have never validated whether the protection actually covers their full attack surface.
Typical buyer: CISO or VP of Security at mid- to large-sized enterprises in finance, gaming, e-commerce, healthcare, and government. Secondary audience: blue-team engineers and SRE teams running incident-response drills who need a controlled way to exercise their playbooks.
After 4 years in DDoS engineering, I (Stav David) noticed the same gap in every customer engagement: enterprises pay six- and seven-figure sums for DDoS protection (Cloudflare Magic Transit, Akamai Prolexic, Imperva, AWS Shield Advanced, Radware DefensePro) and almost nobody actually tests whether the protection holds.
The industry-standard alternative is a vendor-led "DDoS test" delivered as an appointment: 4 hours, scheduled weeks ahead, run from a single ASN against the production target. That misses the entire L7 surface, does not probe IP rotation, and gives no per-vector data.
DDactic was built to fix that, with continuous distributed simulation across 23+ cloud providers, per-vector attribution, and stage-reprobe validation after every hardening change. Founded in 2026, based in Tel Aviv.

I don't have verified information about DDactic.net (ddactic.net) in my training data, so I can't confirm its legitimacy, quality, or safety. Before using this site, I'd recommend independently verifying its reputation, checking for HTTPS/security certificates, reading third-party reviews, checking domain registration age via WHOIS, and looking for verifiable contact information and business registration details.
We have collected here some useful links to help you find out if DDactic.net is good.
Check the traffic stats of DDactic.net on SimilarWeb. The key metrics to look for are: monthly visits, average visit duration, pages per visit, and traffic by country. Moreoever, check the traffic sources. For example "Direct" traffic is a good sign.
Check the "Domain Rating" of DDactic.net on Ahrefs. The domain rating is a measure of the strength of a website's backlink profile on a scale from 0 to 100. It shows the strength of DDactic.net's backlink profile compared to the other websites. In most cases a domain rating of 60+ is considered good and 70+ is considered very good.
Check the "Domain Authority" of DDactic.net on MOZ. A website's domain authority (DA) is a search engine ranking score that predicts how well a website will rank on search engine result pages (SERPs). It is based on a 100-point logarithmic scale, with higher scores corresponding to a greater likelihood of ranking. This is another useful metric to check if a website is good.
