GreyNoise Intelligence focuses on cybersecurity by collecting and analyzing data from Internet-wide scans and attacks. It helps organizations identify which threats can be ignored, allowing security analysts and network administrators to filter out non-threatening traffic. Unlike other cybersecurity firms, GreyNoise offers a subscription service that provides access to its extensive database and analytical tools, enabling clients to concentrate on real risks. The company's goal is to enhance the efficiency of security teams by reducing the number of false positives they need to investigate.
