Why Investors Backed Arms Cyber
Arms Cyber Defense sells endpoint security software that defends against ransomware. Its Raven Platform hides critical files, plants decoys for intruders, and keeps concealed backups for recovery. The company pitches the product to banks, credit unions and fintechs. It is based in Los Gatos, California.
The problem it targets
Brad Potteiger worked on offensive cyber techniques at the state level for the U.S. Intelligence Community. He saw ransomware reach organizations of all sizes, including small businesses, Fortune 500 companies and government agencies. In Arms Cyber's account, defenders fell behind and spent time arguing over the problem rather than fixing it. The company's finance page cites the Ponemon Institute for a 59.7% yearly chance that a financial institution suffers a data breach.
What the product does
Arms Cyber uses a three-part strategy: Conceal, Adapt, Restore. Conceal hides critical files in stealth directories, aimed at blocking both encryption and theft. Adapt plants fake files and assets as decoys. When an intruder touches one, the software raises an alert. Behavioral and entropy-based detection also looks for early signs of encryption. Restore keeps targeted files in concealed enclaves. Arms Cyber's case is that attackers cannot locate or corrupt these enclaves, so hidden backups survive a foothold.
Progress so far
The team page lists leaders beyond the founders: a chief revenue officer, a chief marketing officer, a chief product officer and a vice president of engineering. The Los Gatan reported on November 5, 2025 that the company opened a headquarters in Los Gatos. Arms Cyber's case to financial institutions is that recovery cuts downtime from days or weeks to minutes and average incident cost from $4.1 million to about $84,000.
