Assetnote ASM vs DarknetSearch Attack Surface Discovery: 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.

DarknetSearch Attack Surface Discovery

Mid-market and enterprise security teams drowning in unknown cloud storage buckets and exposed credentials will find real value in DarknetSearch Attack Surface Discovery because it actually monitors paste sites and URL shorteners where your data ends up, not just your registered assets. The platform covers five NIST CSF 2.0 functions including continuous monitoring and adverse event analysis, with API integration into Splunk and Jira making it deployable alongside existing SOC workflows. Skip this if you need internal vulnerability scanning or remediation workflows; DarknetSearch is discovery and notification only, which means you're buying a sensor for your blind spots, not a ticketing engine.
