Attack surface management software helps teams find exposed assets and keep track of them. The ranking starts with Detectify Surface Monitoring, CrowdStrike Falcon Surface and SOCRadar Extended Threat Intelligence Platform. Compare external asset discovery and cloud asset discovery to assess which sources each entry covers, and consider attack-path analysis when you need to examine relationships among exposures. Monitoring frequency indicates how often changes are revisited; asset limits and API access are additional operational fit checks. Free-plan availability and paid-from pricing provide cost context. Weigh these listed capabilities against the assets you need to discover and monitor.
28 attack surface management software ranked on what their makers publish — plans and prices, free tiers, platforms and the facts on their own pages.
