winfunc has autonomously found security vulnerabilities in some of the biggest companies
Get started in 3 simple steps.
Connect Codebase
Link your GitHub repositories securely. We map your architecture instantly.
Autonomous Audit
Receive a deep-dive security audit with PoCs for every vulnerability found.
Continuous Protection
Automated patches via PRs. We scan every commit to keep you zero-day safe.
Zero false-positives.
Guaranteed.
We don't just find potential bugs. We prove them with executable exploits using formal verification.
- Formal verification engine
- Auto-generated Proof-of-Concepts
- Deterministic reproducibility
- No noise, pure signal
Logic aware.
Context driven.
Finds bugs that break your business logic, gaming the system in ways scanners miss.
- Accurate sink-to-source analysis
- Financial logic validation
- Authorization bypass detection
- Business flow manipulation
Uncover the unseen.
Detects race conditions, memory safety issues, and TOCTOU bugs that look correct to the human eye.
- Race condition detection (TOCTOU)
- Memory safety analysis
- Complex state interactions
- Deep fuzzing integration
Predicting the future
of your code.
We analyze evolving code history to predict where security loopholes will emerge before they happen.
- Historical pattern analysis
- Commit-level risk scoring
- Architecture drift detection
- Proactive defense suggestions
Frequently
asked questions.
Winfunc adopts a combination of on-the-fly generated tree-sitter queries, plug-and-play language servers (LSP), and LLM-powered analysis for ingesting codebase context with 100% accuracy.
The team has worked on the problem of "codebase comprehension" for more than a year. Winfunc adopts this work and thus supports all major programming languages. So if you have a codebase written in Haskell, Elixir, Clojure, Lua, or you name it - we support it.
We have demonstrated this by finding vulnerabilities in the old HackerNews codebase written in "Arc", a dialect of Lisp with no parsers out in the wild.
