Shodan vs CloudSEK Attack Surface Management: 2026 Comparison
Shodan is a free external attack surface management tool. CloudSEK Attack Surface Management is a commercial external attack surface management tool by CloudSEK. Compare features, ratings, integrations, and community reviews side by side to find the best external attack surface management fit for your security stack.
CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
Security teams responsible for internet-facing infrastructure need Shodan to find what attackers see before attackers do. The free tier gives you real-time visibility into your own exposed devices, services, and default credentials across millions of internet scans without licensing friction. Skip this if your organization lacks the operational discipline to act on what you find; Shodan surfaces problems faster than most teams can remediate them, which creates noise without a triage process in place.
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.
