GreyNoise

GreyNoise helps security operations center (SOC) teams concentrate on real threats by cutting out false positives and noise from their security monitoring tools. By gathering and analyzing data on internet-wide scanning and exploitation, GreyNoise offers a new perspective that helps analysts triage threats and work more efficiently.

GreyNoise uses a network of sensors to spot and categorize IP addresses that are responsible for noisy traffic. That information lets customers distinguish between real threats and benign or ordinary business activity.

GreyNoise has a few tricks to make security operations easier:

• Accelerate Alert Triage: Classify IP intent to speed up triage.
• Defend Against Mass Exploitation: Spot and block exploit activity that's relevant to a customer's attack surface.
• Automate Alert Reduction: Cut out noisy alerts from security tools.
• Maximize SOC Efficiency: Downgrade events from benign IPs and common business services.

Customers can integrate GreyNoise with their own security tools like SIEM, SOAR and TIP, and use its APIs to automate their own workflows. Visualizer and GNQL (GreyNoise Query Language) abilities let customers drill down into the context of individual IPs for deeper research and ask more sophisticated questions to find other indicators.

GreyNoise offers several tiers of service:

• Free Intelligence: A limited amount of publicly available data useful for research and understanding what's going on on the internet.
• Core Intelligence: A basic package for SOC, CTI and threat hunting teams.
• Edge Intelligence: A custom installation of sensors that produces first-hand scanning intelligence.
• Sovereign Intelligence: Customized services for nation-states and very large organizations.

GreyNoise hopes to make security operations more efficient by cutting the volume of alerts and the time spent on unproductive activity. That means teams can concentrate on real threats and respond more quickly.
