Bright Security Introduces STAR Fuzzer, Agentic Fuzzing That Writes Its Own Harnesses and Proves Every Finding

Bright Security has launched STAR Fuzzer, an agentic fuzzing tool that automatically identifies security-critical functions, generates and verifies a fuzzing harness for each one, searches for faults using an evolutionary engine, and delivers confirmed findings with byte-exact reproducible payloads, without needing a running application. Unlike AFL++/libFuzzer, it removes the manual harness-writing and triage burden; unlike DAST, it tests below the HTTP layer; and unlike LLM code review, it finds unknown bug classes through millions of real executions rather than prediction. In pre-release testing, 45% of projects scanned had High/Critical issues, and in its first month it produced ten published findings across eight projects including the Crystal standard library, htop, and RIOT OS. It supports C/C++, Rust, Go, Java/Kotlin, .NET, Node, Python and Crystal, and runs inside a customer's own environment.
