Cybersecurity startup Armis announced on Wednesday that it is buying Israeli cyber startup Silk Security for $150 million to better protect businesses and organizations from risks as they connect all manner of devices and systems.

Founded in 2022 by CEO Yoav Nathaniel, CPO Or Priel and CTO Bar Katz, Silk Security has built a platform that consolidates, contextualizes and prioritizes security risks and vulnerabilities to help firms and organizations translate the findings into actionable remediation tasks to fix breaches.

To date, Silk Security has raised $12.5 million in funding from Insight Partners, the Crowdstrike Falcon fund, and Hetz Ventures.

Headquartered in Palo Alto, California, Armis was founded in late 2015 to allow companies to adopt new connected devices — without fear of cyberattacks.

“Global enterprises and governments need a platform that can address the entire lifecycle of cybersecurity threats,” said Armis CEO and co-founder Yevgeny Dibrov.

“Given today’s complicated, dynamic threat landscape [and] 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.”

Armis said it plans to integrate Silk’s technology into its own offerings to create an AI-driven cyber threat exposure management platform so that security teams at firms and organizations can monitor and manage all of their security vulnerabilities and findings across connected devices to cloud compute systems in one place and automate remediation of breaches.

“Organizations across the world are struggling to address increasing concerns about security risks to ensure business continuity,” said Nathaniel. “These concerns can be resolved by creating proactive strategies to identify, manage and reduce those risks.”

In 2020, Armis was acquired by US-based Insight Partners, a venture capital and private equity firm, in a cash deal that values the Israeli firm at $1.1 billion. The deal marked the largest ever for a private Israeli cybersecurity firm.
