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 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.
Mid-market and enterprise security teams managing sprawling attack surfaces across cloud, SaaS, and third-party integrations should prioritize ImmuniWeb® Discovery for its dark web monitoring and supplier risk visibility, capabilities most competitors either skip or bolt on as afterthoughts. The platform covers five NIST CSF 2.0 functions including asset discovery, continuous monitoring, and supply chain risk, which means it actually closes gaps in how you map external exposure rather than just flagging what you already know exists. Skip this if your organization needs deep cloud-native workload scanning or has zero tolerance for monitoring capabilities that lean detection over remediation; ImmuniWeb® Discovery is built for visibility-first teams, not for shops that demand integrated response automation.
