TopHat Security, Inc. announced its Series A financing on August 19, 2026. Landolt Securities, Inc. led the round and also served as placement agent on the transaction. The amount was not disclosed.

TopHat builds cybersecurity products made specifically for operational technology, critical infrastructure, government and artificial intelligence environments. Its platform, O-RANGE, is aimed at securing industrial and AI driven systems, a corner of the market that has historically been served by tools designed for ordinary corporate networks.

The company operates from Atlanta. That places the business in Georgia.

Proceeds will go toward advancing the enterprise product portfolio, expanding customer delivery and hitting growth milestones tied to threats aimed at United States government agencies and critical infrastructure operators.
