Automated Undefined Behavior Detection Platform for C/C++
P6/10May 20, 2026
WhatA continuous integration service that deeply analyzes C/C++ codebases for undefined behavior using a combination of static analysis, symbolic execution, and sanitizer-guided fuzzing, delivering actionable fix suggestions.
SignalThe post highlights that undefined behavior in C is pervasive and subtle enough that even experts routinely miss it, yet existing tools only catch the trivial cases — there is no comprehensive, integrated solution that finds the hard UB bugs before they ship.
Why NowModern compiler sanitizers (ASan, UBSan, MSan) and advances in symbolic execution have matured enough to be composed into a much more powerful detection pipeline than any single tool provides, and the security stakes of UB have never been higher with memory-safety mandates from CISA and the White House.
MarketEvery company shipping C/C++ code in safety-critical, embedded, or infrastructure software — defense, automotive, medical devices, OS kernels. TAM in the billions. Competitors include Coverity (Synopsys), Polyspace (MathWorks), and CodeQL, but none offer a unified UB-focused CI pipeline with fix suggestions.
MoatDeep corpus of UB patterns and false-positive tuning data accumulated across customer codebases creates a compounding data advantage that improves detection accuracy over time.
