Security — two complementary lenses
Mythos vs. Perfai Security
Source-code offensive research vs. runtime security. One finds what should never have been written. The other finds what only appears when the app is running.
1
Full-stack coverage — code and runtime
2
Security work compressed from weeks into hours
3
Proven exploits only — no noise, no false positives
4
Auto-fix PRs with retest evidence shipped to devs
Mythos
The code lens
AI-enabled offensive code researcher
Code scanningStatic analysis of source & dependencies
Injection & bad practicesSQLi, XSS, SSRF, secrets, IaC misconfigs
Code modelSingle LLM — Claude, GPT-4o, or Ollama
Code agentAI agent runs pre-merge — blocks vulnerable code before it hits main
Fix guidanceRemediation at code level, PoC exploit generation
Perfai Security
The runtime lens
AI-powered runtime & access-control tester
Runtime testingUI, API, roles & data in live behavior
Access-control issuesPermissions, multi-tenant isolation, privilege abuse, shadow functionality
Multi-model approachVision, code & LLM models combined
Pre-release & contract testingCatches what ships before it ships
Fix & retest loopShips auto-fix PRs, validates the patch not just the finding
Point-by-point
| Mythos | Perfai Security | |
|---|---|---|
| Target | Source code & binaries | Running app: UI, API, roles, sessions |
| Finds | Zero-days, injection, logic flaws in code | Broken access control, privilege abuse, business-logic abuse |
| Requires | Code audit — no app needs to run | Live app with real roles & data |
| Blind spot | Runtime auth behavior | Deep code taint & CVE variant chains |
| Analogy | Red team / offensive researcher | Bug bounty / pre-release pentest |
| Output | PoC exploit + fix hint at code level | Proven exploit + auto-fix PR + retest |
Together they close the full security loop
Mythos finds zero-days, chains exploits, and gates merges before flaws reach production. Perfai Security finds access-control and business-logic bugs that only appear with real roles, real sessions, and real data. Together they compress weeks of security work into hours.
Neither tool replaces the other. Mythos secures the code. Perfai Security secures the running app.
