How GreyNoise Block Helps:

  • Keep Pace with Emerging Threats: Blocklists update in real time as new attacker infrastructure appears, staying effective against fast-moving campaigns.
  • Lower Risk of Overblocking: Real-time lists built from observed attack traffic, not stale third-party feeds. Tune aggressiveness by how recently malicious activity was seen.
  • Buy Time for Remediation: Cut off hostile IPs and CVE exploits before they spread, giving you critical time for longer-term fixes.
  • Reduce Alert Noise: Block mass scanning and exploitation attempts to shrink SIEM logs, cut storage costs, and ease analyst workload.
