sshd-honeypot is a free honeypots & deception tool. Acalvio ShadowPlex is a commercial honeypots & deception tool by Acalvio Technologies. Compare features, ratings, integrations, and community reviews side by side to find the best honeypots & deception 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 running Linux infrastructure who want to observe actual attacker behavior on exposed SSH ports should deploy sshd-honeypot; it intercepts brute force attempts and shell commands in real time without the overhead of full Cowrie instances. The setup is straightforward,a modified OpenSSH daemon that logs to Cowrie,and costs nothing, making it practical for teams that need threat intelligence on SSH reconnaissance patterns. Skip this if you need centralized log aggregation, alerting, or forensics across multiple honeypots; sshd-honeypot is a thin instrumentation layer, not a management platform.
Mid-market and enterprise security teams with exposed APIs, web applications, or IoT infrastructure should use ShadowPlex to catch reconnaissance and credential attacks before they reach production systems. The platform's external-facing decoys generate high-fidelity threat intelligence in STIX format while monitoring for password spraying and brute-force attempts, directly addressing ID.RA and DE.CM in NIST CSF 2.0. Skip this if your attack surface is entirely internal or if you need deep visibility into post-breach lateral movement; ShadowPlex is optimized for early detection at the perimeter, not incident response.
