Side-by-side comparison of AI visibility scores, market position, and capabilities
SaaS security platform managing risks from SaaS-to-SaaS integrations, OAuth grants, and collaboration tool sprawl. Tel Aviv Israel; raised $25M+; Valence discovers and remediates risky third-party app connections across Google Workspace, Microsoft 365, and Slack environments.
About
Valence Security is a SaaS security company founded in 2021 and headquartered in Tel Aviv, Israel. The company identified a growing but underaddressed attack surface: the web of integrations, OAuth grants, and third-party app connections that accumulate as organizations adopt dozens of SaaS applications. Each integration creates a trust relationship that can be exploited if the third-party application is compromised, if a token is leaked, or if permissions are granted far beyond what the use case requires. Valence was built to give security teams full visibility and governance over this SaaS integration mesh.\n\nValence raised $25 million in a Series A round led by Microsoft's M12 venture fund, with participation from YL Ventures and Porsche Ventures. The platform connects to the organization's core SaaS applications — including Microsoft 365, Google Workspace, Salesforce, GitHub, Slack, and Zoom — and discovers all OAuth applications connected to them, the permissions granted, the users who authorized them, and whether the connected applications have known security issues. Security teams can review, revoke, and enforce policies on third-party app access without disrupting end users.\n\nValence's collaboration security capabilities extend beyond OAuth to cover sharing configurations — identifying when sensitive documents, files, or data are shared externally or with overly broad permissions in collaboration tools. The platform also monitors for SaaS misconfigurations and tenant-level security settings that deviate from security baselines. Its remediation workflows allow security teams to alert the responsible users, request justification for sensitive access, or automatically revoke connections that violate policy.
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.
