Permiso vs Island Technology
Side-by-side comparison of AI visibility scores, market position, and capabilities
Davis CA universal identity security platform; raised $18M+; detects identity-based threats across cloud control planes and human and machine identities.
About
Permiso is a cloud identity security company founded in 2021 and headquartered in Davis, California. The company was founded by Paul Nguyen and Ian Ahl, former security leaders from FireEye, Mandiant, and Amazon, to address the rapid growth of identity-based attacks in cloud environments. As organizations moved workloads to the cloud, the cloud control plane — the APIs and IAM systems that manage cloud infrastructure — became a primary attack target. Attackers who compromise cloud credentials can provision malicious infrastructure, exfiltrate data, or pivot laterally across cloud accounts without triggering traditional network-based detection.\n\nPermiso raised $18 million in seed and Series A funding from investors including Base10 Partners, Work-Bench, and Okta Ventures. Its platform analyzes activity from cloud identity providers and control planes — AWS CloudTrail, Azure Activity Logs, GCP Audit Logs, Okta, and others — to build behavioral models for every human user and machine identity. When an identity behaves in an anomalous way, such as an IAM role making API calls it has never made or a user accessing services outside their normal patterns, Permiso generates an alert with full context about what happened and what resources were affected.\n\nPermiso's Universal Identity Graph correlates activity across multiple cloud environments and identity providers into a single timeline per identity, enabling analysts to trace attack chains across organizational boundaries. The platform is particularly valuable for detecting techniques used in sophisticated cloud attacks such as credential theft, IAM privilege escalation, persistence via new IAM roles, and lateral movement between cloud accounts. Permiso also provides a free cloud investigation tool called CloudGrappler used by threat intelligence researchers.
Dallas TX enterprise browser platform; raised $490M+; secure Chromium-based browser giving IT full control over web application access and data flows.
About
Island Technology is an enterprise browser company founded in 2020 and headquartered in Dallas, Texas. The company was founded by Michael Fey and Dan Amiga to reimagine how enterprises secure access to web applications by moving security controls into the browser itself rather than relying on network perimeters that have become irrelevant in a cloud and remote-work era. Island built an enterprise browser based on the Chromium engine that is functionally identical to Google Chrome for end users but gives IT and security teams complete control over what data can be accessed, copied, printed, screenshotted, or uploaded within each web application.\n\nIsland raised $490 million across multiple funding rounds including a $250 million Series D, valuing the company above $3 billion. The platform addresses use cases across contractor and third-party access, BYOD environments where employees use personal devices to access corporate applications, and zero-trust access control for web-based SaaS applications. Because the enterprise browser sits directly in the data path between the user and every web application, it can enforce granular policies — for example, preventing a contractor from copying data from Salesforce while still allowing them to read it — without requiring VPNs, virtual desktops, or complex network configurations.\n\nIsland's browser also provides deep telemetry on user activity within web applications, enabling security teams to detect risky behavior, investigate incidents, and conduct phishing-resistant authentication. It integrates with major identity providers for SSO, with DLP platforms for data classification, and with SIEM tools for activity logging. The company has attracted customers in financial services, healthcare, legal, and technology sectors where sensitive data access by third parties and remote workers is a significant security challenge.
