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 mail infrastructure who want to see what attackers are actually probing for will get fast intelligence from SMTP Honeypot's configurable responses and automatic extraction of reconnaissance attempts. The free pricing and minimal setup overhead mean you can spin it up in an afternoon on a non-production network segment to feed your threat intel program. Skip this if you need centralized management across multiple honeypot types or expect vendor support; this is a single-purpose tool best suited to teams comfortable running open-source infrastructure.
