CST VerdictShort answer
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. MSPs managing Microsoft 365 for dozens of tenants should pick SaaS Alerts Fortify if policy drift across accounts is eating your compliance time; it automates what would otherwise require manual tenant-by-tenant configuration work. The centralized Secure Score dashboard with regression alerts means you catch security backsliding across your customer base before audits do, covering the GV.OV and PR.PS functions that most MSPs leave on autopilot. Skip this if your customers are primarily on Google Workspace or hybrid environments where Microsoft 365 is secondary; the tight Microsoft-only integration is a strength for pure-play M365 shops and a real limitation everywhere else.
