Armis Acquires Cyber Platform Silk Security for $150M

Armis, a cybersecurity startup, paid $150 million for Silk Security, a platform for prioritizing and remediating cyber risks, marking the company’s second acquisition in two months.

The transaction follows Armis’ February acquisition of Cyber Threat Cognitive Intelligence, a business that tracks real-world exploits of vulnerabilities.

“Silk Security’s technology will immediately be integrated into Armis’ platform to enable organizations to close the legacy gap between security findings and actionable remediation that secures the attack surface, ensures operational resilience and establishes efficient and effective business processes, a spokesperson told Connect Money.

Silk Security was formed in 2022 by Yoav Nathaniel, CEO; Or Priel, CPO; and Bar Katz, CTO. The startup raised $12.5 million from Insight Partners, the Crowdstrike Falcon fund, and Hetz Ventures, revealed in the summer of 2023 when it emerged from stealth mode.

Armis has spent the last eight years designing and developing its AI-powered Armis Centrix platform to address all aspects of cyber threat exposure management, from asset discovery and management to vulnerability discovery, prioritization, and now remediation.

“To ensure the entire attack surface is both defended and managed in real time, organizations need a comprehensive solution that quantifies and reduces risk continually through the ability to prioritize and remediate the most important security findings at any given time, in any environment,” said Yevgeny Dibrov, CEO and co-Founder, Armis.

The acquisitions follow Dibrov’s announcement last fall that Armis is ramping up its efforts for an initial public offering in the second half of 2024.

Armis was valued at $3.4 billion following its $300 million investment round in November 2021, making it one of the most valuable cybersecurity “unicorns.”
