TLDRs;
- Cisco is acquiring Astrix Security for roughly $400 million to strengthen its growing AI-focused cybersecurity portfolio.
- The deal targets rising security risks tied to non-human identities, including AI agents, APIs, bots, and service accounts.
- Cisco plans to integrate Astrix technology into major platforms including Duo, Splunk, and Cisco Identity Intelligence.
- Growing enterprise AI adoption is accelerating demand for machine identity protection across cloud and automated systems.
Cisco Systems stock traded steadily after the networking and cybersecurity giant announced the acquisition of Israeli startup Astrix Security for approximately $400 million. The transaction highlights Cisco’s broader strategy to deepen its position in AI-driven cybersecurity as businesses rapidly adopt automated systems and AI agents.
Astrix specializes in securing non-human identities, a category that includes machine accounts, software bots, API credentials, cloud workloads, and autonomous AI agents. As companies deploy more AI-powered systems, these digital identities are becoming critical infrastructure, and increasingly attractive targets for cybercriminals.
Cisco confirmed that Astrix’s capabilities will be incorporated into several of its existing security offerings, including Cisco Identity Intelligence, Duo, Secure Access, and Splunk. The company believes the acquisition will help enterprises gain stronger visibility into machine-to-machine activity across complex cloud environments.
The move arrives during a period when cybersecurity vendors are racing to address emerging vulnerabilities tied to AI deployment and automated enterprise operations.
Machine Identity Market Expands
The market for machine identity management has grown rapidly as enterprises move more workloads into the cloud and automate internal operations. Industry estimates suggest large corporations can manage hundreds of thousands of non-human identities simultaneously, often vastly outnumbering human user accounts.
Analysts tracking the sector expect the global machine identity security market to expand sharply over the next decade as AI adoption accelerates. Businesses are increasingly relying on APIs, cloud services, and autonomous tools that require secure authentication without direct human involvement.
This rapid growth has created new risks. Compromised API keys, service accounts, and machine credentials have become common entry points for cyberattacks targeting enterprise cloud systems.
Security experts warn that AI agents could further complicate identity management because automated systems increasingly interact with each other independently. Without proper oversight, these systems can create hidden vulnerabilities across enterprise networks.
Cisco’s acquisition positions the company to compete more aggressively in this evolving segment as rivals also expand AI security capabilities through acquisitions and in-house development.
Astrix Strengthens Cisco Portfolio
Founded in 2021 by Alon Jackson and Idan Gour, Astrix quickly attracted investor attention for its focus on non-human identity security. The startup raised approximately $85 million in funding from firms including Menlo Ventures, Workday Ventures, Bessemer Venture Partners, CRV, and F2 Venture Capital.

Its latest funding round came in late 2024, when the company secured $45 million to expand product development and enterprise adoption.
Cisco sees Astrix as a strategic fit within its broader cybersecurity ecosystem. By integrating Astrix technology into products already used by major enterprises, Cisco could offer customers a more unified approach to identity security across humans, machines, and AI systems.
The acquisition also aligns with a broader trend across the cybersecurity industry. Large vendors are increasingly combining privileged access management, identity governance, and cloud workload security into integrated platforms.
Meanwhile, companies like Microsoft have also introduced AI-focused identity protection tools as competition intensifies in the sector.
