CST VerdictShort answer
Mid-market and enterprise teams managing OT and IoT device security will find aDolus FACT uniquely useful because it analyzes compiled binaries without needing source code, solving the core problem of tracking vulnerabilities in embedded systems you don't control. The vendor maps CVEs to actual products through AI-driven correlation rather than guesswork, and supports Windows, QNX, Linux, and real-time operating systems across a single platform. Skip this if your priority is IT-only asset management or you need pre-built integrations beyond AWS; the small vendor footprint means integration roadmap moves slower than market leaders. Startup development teams shipping fast need Perisai Web Scanner because it catches vulnerable dependencies and misconfigured headers in minutes without requiring infrastructure changes. The free tier covers automated scanning across JavaScript libraries and HTTP security posture, removing the cost barrier that usually delays security scanning adoption. Skip this if you're managing legacy monoliths with hundreds of interconnected services or need continuous runtime monitoring post-deployment; Perisai maps application risk at scan time, not in production.
