Strengthening OT Defense, Zero Trust: SSH’s Strategic Vision

OT security plays a critical role in protecting infrastructure and industrial systems from increasingly sophisticated cyberthreats. That’s why SSH Communications Security is investing in OT security solutions, said Rami Raulas, who spoke to Information Security Media Group this week after settling in to his new role as interim CEO of the Finnish cybersecurity company.

“Most of the ransomware today occurs in OT, where systems were not designed with security in mind,” Raulas said. “Operational technology, by definition, was built for efficiency and productivity, not for security, making it the easiest to attack.”

SSH under Raulas also plans to build on existing investments around enhancing key management to prevent unauthorized access and developing quantum-resistant encryption to protect against future threats. The company has also made gains in expanding its zero trust architecture to ensure secure, minimal privilege access across all operations (see: SSH Exec Rami Raulas Named Interim CEO in Finnish Shakeup).

In this video interview with Information Security Media Group, Raulas also discussed:

• The importance of zero trust frameworks that minimize the misuse of access credentials;
• How SSH has fortified the defenses of critical infrastructure to act as a digital gatekeeper;
• How to prepare for when quantum computing could break current encryption methods.

Raulas, who joined SSH Communications Security in 2016, has served on the company’s executive management team as head of EMEA since 2021. He previously held international leadership positions in sales and business management, marketing, and product management in global companies. His previous employers include Ahlstrom, Aspocomp, ICL, Fujitsu, Fujitsu-Siemens and Nokia.
