Assetnote ASM vs CybelAngel Attack Surface Management: Side-by-Side Comparison (2026)

Assetnote ASM

Mid-market and enterprise security teams managing sprawling external infrastructure will get the most from Assetnote ASM because its hourly asset discovery actually catches exposures before your business units spin up new services, not weeks after. The platform covers ID.AM and DE.CM across NIST CSF 2.0, meaning you're building a real asset inventory while monitoring it continuously, and the exploit-based verification eliminates the noise that buries actionable findings in traditional scanners. Skip this if your organization lacks the headcount to operationalize a workflow-driven program; Assetnote's strength is enabling lean teams to prioritize, not giving you a dashboard to ignore.

CybelAngel Attack Surface Management

Mid-market and enterprise teams drowning in exposed credentials and forgotten cloud assets will find real value in CybelAngel's daily monitoring of 6 billion data points paired with dedicated analyst support; the dark web credential intelligence catches breaches before attackers weaponize them at scale. The vendor's inclusion of M&A due diligence and third-party risk assessment means you're not bolting on separate tools for those critical workflows. Skip this if your organization needs continuous endpoint detection or internal network visibility; CybelAngel is exclusively external-facing and won't replace your internal monitoring stack.
