Acalvio ShadowPlex Advanced Threat Defense
Mid-market and enterprise security teams with hybrid infrastructure will get the most from ShadowPlex Advanced Threat Defense because it catches lateral movement and reconnaissance that perimeter tools miss, using AI-powered deception assets across on-premises, cloud, and OT environments simultaneously. The platform's 350+ prebuilt deception assets and agentless deployment mean you're detecting APT behavior within days, not months of tuning. Skip this if your team lacks the SOC maturity to act on high-fidelity alerts or if you're looking for a tool that also handles incident response and recovery; ShadowPlex prioritizes early detection over post-breach containment.
Security teams running constrained infrastructure or lab environments who need a lightweight honeypot for early warning of reconnaissance will appreciate Portlurker's minimal footprint and protocol-agnostic listening. Written in Rust, it consumes virtually no CPU or memory overhead while still capturing connection attempts and guessing service types; the SQLite logging keeps data local and queryable without external dependencies. Skip this if you need centralized alerting, correlation with other sensors, or anything beyond passive observation of what's touching your ports.
