Founded by top CTF players (perfect blue) and it shows in exploit-oriented depth; strong across EVM plus the harder-to-staff ecosystems (Move/Aptos/Sui, Solana, ZK circuits); reports are concrete and reproduction-focused, and the firm has credible public vuln research beyond paid audits.
GPT Strong offensive-security culture, fast execution, broad EVM plus Move/Sui and ZK capability, extensive public work, and effective use of fuzzing, static analysis, and formal techniques make it a strong merit-to-turnaround choice.
