What it does
CrowdSec provides threat-intelligence and blocklist products based on observed malicious IP activity, with integration options for defensive systems.
CrowdSec's current homepage centers on malicious-IP intelligence and blocklists. An administrator can evaluate how those lists fit an existing firewall or application-defense workflow rather than treating a feed as a standalone investigation system. Define where a block is enforced and how a legitimate user can report a mistake. The page's lead-time and coverage comparisons are vendor claims.
