CrowdStrike buys SGNL to strengthen next-gen identity security

CrowdStrike

CrowdStrike and SGNL have entered into a definitive agreement that will see CrowdStrike acquire SGNL as part of a push to reshape identity security for the AI era.

The acquisition is intended to accelerate CrowdStrike’s leadership in next-generation identity security by enabling access for human, non-human and AI identities to be continuously granted and revoked based on real-time risk. The value of the deal was not disclosed.

By bringing SGNL into its portfolio, CrowdStrike aims to extend dynamic authorisation across SaaS environments and hyperscaler cloud access layers. The company said the combination of dynamic privilege and access management with Falcon platform intelligence will establish a new standard for what it describes as agentic identity security, as AI agents increasingly operate with elevated access across enterprise systems.

CrowdStrike provides cloud-native cybersecurity solutions designed to stop breaches by correlating threat intelligence across endpoints, cloud workloads, identities and SaaS applications. Its Falcon® platform already supports a broad identity security stack, covering initial access prevention, privileged access management, identity threat detection and response, SaaS identity security and agentic identity protection across hybrid environments.

SGNL operates as a runtime access enforcement layer between modern identity providers and the SaaS and cloud resources accessed by people, non-human identities and AI agents. Its technology evaluates identity, device and behavioural signals in real time, allowing access to be dynamically granted, denied or revoked as risk conditions change. This approach is designed to eliminate standing privileges and address the limitations of static access models that cannot adapt to evolving threats.

The acquisition comes as identity security rapidly becomes one of cybersecurity’s fastest-growing segments. According to IDC, the identity security market is expected to grow from approximately $29bn in 2025 to $56bn by 2029, driven by the expansion of AI agents and other high-privilege non-human identities operating across distributed cloud environments.

CrowdStrike said integrating SGNL will allow Falcon Next-Gen Identity Security to extend just-in-time access controls beyond traditional directories to cloud identity and SaaS systems such as AWS IAM and Okta. The combined capabilities are also expected to strengthen identity governance and downstream protection by revoking access beyond the identity provider and reducing the risk of misconfiguration-driven breaches.

CrowdStrike CEO and founder George Kurtz said, “AI agents operate with superhuman speed and access, making every agent a privileged identity that must be protected. With SGNL, CrowdStrike will deliver continuous, real-time access control that eliminates the known and unknown gaps from legacy standing privileges. We’re disrupting the premise of modern privilege and access – for every identity, human or machine. This is identity security built for the AI era.”

SGNL CEO and co-founder Scott Kriz said, “SGNL was founded to connect access decisions with business reality. The world needs our technology to eradicate the significant risk that legacy standing privileges expose in today and tomorrow’s environments. Joining CrowdStrike provides us with global scale natively through cybersecurity’s leading platform to transform enterprise security with Continuous Identity, furthering CrowdStrike’s mission of stopping breaches.”
