About
Security analysis for teams shipping C and C++.
Vartia is a security engineering consultancy that finds recurring vulnerability patterns in C/C++ codebases and builds automated detectors to stop them from coming back.
The Problem
Most security tooling generates alerts. Hundreds of them, with no evidence that any represent a real, exploitable bug. Teams burn cycles triaging false positives while the same structural defects (buffer overflows in the same parsing path, integer overflows in the same arithmetic pattern) ship again in the next release.
The industry treats each CVE as an isolated incident. We treat them as symptoms of recurring structural patterns. Find the pattern, build the detector, and the entire family stops coming back.
Our Approach
A Vartia engagement starts with your codebase's vulnerability history. We build each historical vulnerability against its original commit, reproduce the failure conditions, and classify bugs into structural families. Then we develop static analysis detectors for each family and validate them by testing against the historical vulnerable and fixed code.
The deliverable is a prioritized report organized by bug family, with detection coverage for each, linked proof artifacts (static analysis queries, sanitizer traces, crash reproductions), and a clear map of what is covered, what is partially covered, and what still requires manual review. Every finding is backed by a concrete witness. If we can't produce one, we don't report it.

What an Engagement Looks Like
Scoping Call
We identify the target codebase or dependencies, known pain points, and existing security tooling. Free, 30 minutes.
Historical Analysis & Classification
We build historical vulnerable and fixed versions, reproduce failures with sanitizers, and classify findings into bug families. Typical duration: 2–4 weeks.
Detector Development & Report
We deliver a prioritized report with bug families, detection coverage, linked proof artifacts, and (where applicable) ready-to-deploy detectors for CI integration.
