Assetnote ASM vs Clear Infosec 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.

Clear Infosec Attack Surface Management

Mid-market and enterprise security teams drowning in shadow assets and third-party risk will find the most value in Clear Infosec Attack Surface Management because it actually tracks what you don't know you own, then ties exposure back to supply chain connections. The Mandiant threat intelligence integration means you're seeing your gaps through an attacker's lens, not just a compliance checklist. Skip this if your organization has fewer than 50 employees or already has mature internal asset inventory processes; the tool's strength is surfacing unknowns at scale, which doesn't solve the problem if you already have one.
