Armis Expands OT/CPS Security Capabilities with $120 Million Otorio Acquisition

Armis, a company specializing in cyber exposure management and security, has acquired Israeli cybersecurity firm Otorio in a deal estimated at approximately $120 million. While financial details were not officially disclosed, market sources indicate that the acquisition strengthens Armis' presence in the operational technology (OT) and cyber-physical systems (CPS) security sectors. This marks Armis' third acquisition within the past year as it continues to expand its platform and position itself for a potential initial public offering (IPO).

With this acquisition, Armis will integrate Otorio's Titan platform into its Centrix cyber exposure management suite, enhancing its ability to provide comprehensive security for industrial operations. The move also enables Armis to offer on-premises CPS security solutions for industries that require air-gapped environments, including energy, utilities, and manufacturing.

According to Armis CEO and Co-founder Yevgeny Dibrov, industries are experiencing increasing security demands, particularly in sectors that require hybrid environments for complete protection. By acquiring Otorio, Armis aims to deliver a fully air-gapped security solution that ensures critical infrastructure and heavy industry remain secure against cyber threats.

Strengthening OT Security for Industrial Sectors

Founded in 2018 by Daniel Bren and Yair Attar, Otorio specializes in cybersecurity solutions for industrial environments, offering proactive protection against cyber risks in sectors such as oil and gas, manufacturing, and utilities. The company’s expertise in securing air-gapped and converged environments aligns with Armis' broader vision of providing robust security for industrial operations.

This acquisition expands Armis' platform with new capabilities, including secure remote access (SRA) for Zero Trust security and advanced attack path mapping, further reinforcing its position in critical infrastructure protection. With the integration of Otorio's technology, Armis aims to provide industries with enhanced visibility and risk management in increasingly complex operational environments.

The acquisition is part of Armis' ongoing expansion strategy. Prior to Otorio, the company acquired AI security startup CTCI and risk prioritization startup Silk Security, demonstrating a strong commitment to strengthening its security offerings. These acquisitions have been seamlessly integrated into the Centrix platform, contributing to a significant increase in revenue from related security services.

Armis Positions Itself for Public Markets

Industry analysts view Armis' recent acquisitions and financial milestones as key indicators of its preparation for an IPO. In October 2024, the company secured $200 million in funding at a valuation of $4.3 billion, fueling its expansion into new security domains.

Commenting on the acquisition, Otorio CEO and Co-founder Daniel Bren emphasized that Armis has quickly established itself as a leading provider of cyber exposure management solutions, offering unmatched visibility, security, and risk management across multiple industries. He expressed enthusiasm about Otorio joining forces with Armis, highlighting their shared commitment to helping businesses achieve complete cyber resilience.

As Armis continues to scale its operations and enhance its security portfolio, the acquisition of Otorio underscores its strategy of consolidating OT and CPS security solutions, ensuring comprehensive protection for critical infrastructure worldwide.
