Based on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
Mid-market and enterprise security teams drowning in shadow IT and forgotten assets will get the most from Siemba EASM because it discovers external-facing infrastructure without needing credentials or network access. The platform maps to all four relevant NIST CSF 2.0 functions,Asset Management, Risk Assessment, Continuous Monitoring, and Infrastructure Resilience,which reflects real coverage across the attack surface lifecycle rather than point-in-time scanning. Skip this if your organization already has mature asset inventory processes or if you need deep integration with existing ticketing workflows; Siemba prioritizes discovery and monitoring visibility over downstream remediation automation.
Strobes Attack Surface Management
Mid-market and enterprise security teams drowning in shadow IT and forgotten domain sprawl will see immediate ROI from Strobes Attack Surface Management; it finds what your inventory doesn't know exists, then actually tells you which discoveries matter through business-context risk scoring rather than raw vulnerability counts. The platform covers ID.AM and ID.RA deeply across cloud, endpoints, and web properties, with real-time monitoring that catches emerging exposures before they're weaponized. Skip this if you need post-breach forensics or insider threat detection; Strobes is discovery and prevention, not response.
