Compare features, ratings, integrations, and community reviews side by side to find the best external attack surface management fit for your security stack.
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 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.
CloudSEK Attack Surface Management
Mid-market and enterprise security teams drowning in shadow IT and undocumented digital assets need CloudSEK Attack Surface Management because it finds what you don't know you're exposing, not just monitors what you already cataloged. The platform maps NIST ID.AM asset management by discovering external-facing infrastructure across cloud, DNS, and third-party integrations that traditional vulnerability scanners miss. Skip this if your attack surface is already fully inventoried or you're looking for a replacement for your existing ASM tool; CloudSEK excels at the discovery phase and is less differentiated once baseline assets are known.
