TopHat Security, Inc., a specialist provider of purpose-built cybersecurity solutions for operational technology, critical infrastructure, government and artificial intelligence environments, has announced a Series A financing round led by Landolt Securities, Inc.
Landolt Securities acted as both lead investor and placement agent for the round, underscoring its confidence in TopHat Security’s approach to protecting the operational systems underpinning national infrastructure.
The fresh capital will be directed towards expanding TopHat Security’s enterprise product suite, scaling customer delivery and hitting a series of growth targets as the firm positions itself against a rising wave of threats aimed at US government bodies and critical infrastructure operators.
At the centre of TopHat Security’s offering sits O-RANGE, an operational technology range and emulation platform built to work alongside existing OT security tools. The platform allows organisations to build high-fidelity digital twins of plants, industrial systems and other OT environments, replicating assets, network relationships, firmware, software, control systems and physical processes in a contained setting.
Working within this virtual environment, asset owners and security teams can map out attack paths, probe vulnerabilities, run through cyber kill chains, trial potential fixes and stress-test facility resilience, all without putting live production systems in harm’s way.
By pulling in data from an organisation’s existing OT security and asset-visibility tools, O-RANGE also helps teams move past static vulnerability lists, weighing up the operational fallout of a given security decision, spotting compensating controls, confirming remediation plans and ranking actions by safety, security, cost and operational impact.
Beyond O-RANGE, TopHat Security’s wider portfolio spans OT and industrial network visibility, asset discovery, cyber supply-chain security and AI infrastructure protection. Combined, these tools are intended to help organisations map their systems, assess risk in operational context, trial security decisions safely and strengthen resilience against an evolving threat landscape.
TopHat Security, Inc. founder and CEO Matt Caldwell said, “Critical infrastructure organizations are receiving more vulnerability information than ever, but they often lack a safe and practical way to understand what those vulnerabilities mean to their actual operations. O-RANGE gives teams a realistic environment in which they can test an investigation, remediation, or attack scenario before making changes to a live facility.
“With this Series A investment and the support of our investors at Landolt Securities, we are confident that TopHat Security can reach the milestones ahead of us, scale our delivery, and help protect the government and critical infrastructure systems on which our country depends.”
