TopHat Security said Aug. 19 that it completed a Series A financing led by Landolt Securities to expand its OT security platform and cybersecurity portfolio.

TopHat Security, Inc. said Tuesday it completed a Series A financing led by Landolt Securities, Inc., to expand its O-RANGE operational technology security platform and broader cybersecurity portfolio.

The company said the investment will support product development, customer delivery and growth milestones tied to threats facing U.S. government agencies and critical infrastructure operators. TopHat Security describes itself as a provider of cybersecurity solutions for operational technology, critical infrastructure, government and artificial intelligence environments.

Why it matters

TopHat Security said the financing will give it more capital to develop a product line for industrial and government environments where teams test cyber defenses without risking live systems. The company is pitching the platform to operators that manage plants, industrial systems and other OT environments.

Context and background

TopHat Security identified O-RANGE as its flagship OT security product. The company said the platform is designed as an operational technology range and emulation tool that complements existing OT security systems.

According to the release, O-RANGE can build high-fidelity digital twins of plants, industrial systems and other OT environments. The company said those digital twins can include assets, network relationships, firmware, software, control systems and physical processes.

TopHat Security said the platform can help teams model attack paths, investigate vulnerabilities, rehearse cyber kill chains, evaluate remediations and test resilience without putting production systems at risk.

The release also said the company’s broader portfolio includes OT and industrial network visibility, asset discovery, cyber supply-chain security and AI infrastructure protection.

What officials said

Matt Caldwell, founder and chief executive of TopHat Security, said critical infrastructure organizations are getting more vulnerability information than ever but often lack a safe, practical way to understand what it means operationally. He said O-RANGE lets teams test investigations, remediation or attack scenarios before changing a live facility.

Don McKiernan, principal at Landolt Securities, said protecting government systems, critical infrastructure and AI infrastructure is paramount to national security. He said Landolt was impressed by TopHat Security’s technology, intellectual property and speed of execution.

What happens next

TopHat Security said the financing will help it pursue growth milestones and expand customer delivery. The company also pointed to its recent participation in the ICS Village at DEF CON 34 in Las Vegas, where Caldwell presented a talk on Aug. 9.

The release did not disclose the size of the Series A round.
