Hysolate
Last updated: Apr 27, 2026
Israeli endpoint isolation platform enabling secure, isolated workspaces on devices to protect sensitive data from risky activities while maintaining user productivity.
Visit WebsiteCompany Overview
Hysolate was an Israeli cybersecurity company founded in 2016 that developed hardware-assisted endpoint isolation technology designed to address a fundamental challenge in modern enterprise security: enabling knowledge workers to access untrusted resources (websites, applications, files) without compromising protected corporate environments or classified information. The company developed a lightweight isolation architecture allowing organizations to create separate, sandboxed workspaces on employee devices—separating casual browsing, email, and external collaboration from secure corporate and classified compartments.
The core innovation underlying Hysolate's platform was the integration of endpoint isolation with user experience. Rather than forcing organizations to choose between security lockdown and user flexibility, the technology allowed enterprises to permit risky activities within isolated containers. This addressed a persistent organizational challenge: security policies that overly restrict productivity encourage circumvention and shadow IT, while policies that prioritize user access create attack surface. Hysolate's isolation approach enabled both security and productivity by eliminating this trade-off at the technical layer.
The company positioned itself specifically for government, defense, and high-security enterprises. Government organizations handling classified information face regulatory and operational requirements for strict compartmentalization of systems and data. Hysolate's isolation technology offered a mechanism to meet compartmentalization requirements on standard endpoints without the cost, complexity, and user friction of managing separate hardware devices. This positioned the company squarely at the intersection of the government procurement market and the defense-industrial technology ecosystem.
Hysolate achieved mid-stage growth and validation through government customer adoption, securing Series B funding and building a team of 50+ employees. The company's focus on government and defense markets aligned it with strategic buyers in the cybersecurity infrastructure space. The company was ultimately acquired by Fortinet, a major security vendor, which integrated Hysolate's isolation technology into the FortiMail Workspace Security suite, reflecting validation of the isolation approach within broader defense-in-depth endpoint security strategy.
The technical approach combined lightweight hypervisor technology, hardware virtualization, and privileged application sandboxing to achieve isolation with minimal performance overhead—a critical requirement for adoption in knowledge-work environments. Hysolate's architecture prioritized seamless user experience while maintaining strong security boundaries, allowing compartmentalization without requiring substantial device management overhead or user retraining.
Dual-Use Assessment
Hysolate's endpoint isolation technology has direct and substantive dual-use applicability. Commercially, it protects enterprises against data exfiltration, malware, and insider threats by isolating risky user activities. For government and defense, it addresses regulatory compartmentalization requirements for classified information handling, enabling compartmented access to classified networks on shared endpoints without requiring separate hardware. The technology is particularly valuable for contractor personnel, remote government workers, and multi-classification environments where cost and user experience preclude hardware compartmentalization. Defense and intelligence agencies require strong separation of classified and unclassified work, making this technology directly applicable to defense posture. The isolation mechanism is robust enough to support separation of information at different classification levels and eligibility requirements.
Strategic Fit Assessment
Hysolate was acquired by Fortinet and is no longer an independent direct-diligence target. The company achieved successful government and defense adoption, demonstrated technology-market fit in compartmented security, and validated the commercial viability of endpoint isolation. While the technology remains strategically important, the startup itself is no longer available for investment and is integrated into a larger vendor's product suite. For readers evaluating exposure to endpoint isolation technology with government/defense applications, the focus should shift to later-stage independent companies or emerging platforms in the compartmentation and zero-trust architecture space.
Strategic Value to U.S.-Israel Alliance
Hysolate's isolation technology demonstrated strategic value for government and defense procurement, successfully validating an architectural approach to compartmentalization that reduces cost and friction compared to hardware-based solutions. The acquisition by Fortinet underscores the strategic importance of isolation in modern endpoint security. For allied defense organizations, compartmentation of classified and unclassified information on shared endpoints reduces operational friction and cost while maintaining security compliance. The technology's integration into broader security platforms reflects its role as a foundational capability in defense-in-depth endpoint security.
