Perisai Web Scanner is a free security scanning tool by Peris.ai. ThreatDown Patch Management is a commercial security scanning tool by ThreatDown by Malwarebytes. Compare features, ratings, integrations, and community reviews side by side to find the best security scanning fit for your security stack.
Based on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
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.
SMB and mid-market teams drowning in patch backlogs will benefit most from ThreatDown Patch Management's CVE prioritization engine, which surfaces the vulnerabilities actually exploited in the wild rather than forcing you to remediate everything equally. The platform covers both PR.PS (platform hardening through systematic patching) and ID.RA (risk-informed remediation), meaning you patch based on what matters to your environment, not vendor severity ratings. Skip this if you need agent-free patching across air-gapped networks or demand extensive third-party OS support beyond Windows and macOS; ThreatDown's strength is velocity over breadth.
