Stop Attackers in Their Tracks

Block Edge Exploitation Based on Real-Time IP Activity

When a zero-day or novel exploit emerges, time is everything. Traditional tools like CVSS, EPSS, and vendor advisories don’t confirm if a vulnerability is seeing active exploitation — GreyNoise does.

GreyNoise is improving Dynamic Blocklists to make them easily consumable and to give teams real-time visibility into active edge exploitation — so you can block threat actors with certainty.

The Problem with Traditional Approaches

• Static Defenses Fall Behind
  Attack behavior evolves by the hour — your blocklists should too.
  
  
• Critical Delay = Critical Exposure
  Slow detection leaves systems vulnerable before patches are ready.

• Blind Spots in Exploitation Visibility
  Risk scores alone can’t tell you what’s actively being exploited in the wild.

How GreyNoise Blocklists Help

Real-Time Threat Confirmation

• Identify IPs actively scanning or exploiting known vulnerabilities.
• Link attacker behavior to specific CVEs with context-rich telemetry.
• Detect and defend against resurgent vulnerabilities that can remain dormant for extended periods before suddenly reappearing. 

Dynamic, Targeted Blocking

• Block based on known attacker infrastructure, not just static rules.
• Tailor defenses to real-world threats: RCEs, brute force, and more.
• Classify IPs as Malicious, Suspicious, or Benign for faster decision-making.
• Protect critical assets if immediate patching isn’t feasible.
