Cobalt Attack Surface Monitoring
Mid-market and enterprise security teams that struggle to track what's actually exposed on the internet should start here; Cobalt Attack Surface Monitoring finds shadow IT and unmapped assets that traditional vulnerability scans miss through daily domain reconnaissance. The daily scan cadence and first-seen timestamps give you continuous monitoring that actually maps to NIST ID.AM and ID.RA, which most ASM tools only pretend to cover. Skip this if your organization doesn't have verified domain ownership set up or if you need pentest orchestration beyond coverage tracking; Cobalt is asset discovery and exposure evaluation, not a replacement for active vulnerability management.
