It continuously scans the global internet, analyzing DNS data, SSL certificates, response headers, and code repositories to answer one critical question: “What internet-facing assets belong to your organization that you don’t already know about?” The name is deliberate. In land surveying, a groma was a Roman instrument used to lay out straight lines and right angles—to map the unknown. Bitsight Groma does the same for cybersecurity. It maps the chaotic, sprawling expanse of your digital footprint and turns it into a precise, actionable grid. The 3 Problems Groma Solves Most security teams are flying blind.

When you acquire a company, you inherit their security debt. Traditional questionnaires miss 30%+ of an acquired company’s external assets. Groma provides an instant, unbiased inventory of the target’s attack surface before the deal closes, preventing nasty post-merger surprises.
Without Groma, that database would have been discovered by a ransomware group, not a security team. You can have the best EDR, the best firewall, and the best SOC in the world. But if you don’t know that an abandoned WordPress site or a misconfigured cloud storage bucket is sitting on your perimeter, those controls are irrelevant.
It gives you the complete, real-time map of your digital territory. And in cybersecurity, you cannot defend what you cannot see. Ready to discover what’s hiding in your digital shadow?
