Menlo Security Acquires Votiro to Deliver Easy, AI-driven Data Security to Enterprises
Read Blog
Frost & Sullivan published its latest Radar Report for the Zero Trust Browser Security (ZTBS) market, naming Menlo Security as a Global Leader and a ‘Company to Action’ in 2026 and beyond. Already established as a global powerhouse, Menlo Security holds the #2 position in global market share at 18.7%. Menlo was placed in the high-growth, highly innovative quadrant—a testament to the company’s successful strategic pivot from remote browser isolation (RBI) to a comprehensive browser security solution.
The enterprise security perimeter has officially moved to the browser. We are witnessing a massive replacement of "heavy" legacy infrastructure, such as VPNs and VDI, in favor of lightweight, browser-native solutions that offer clientless, user-friendly access. According to the report, “[T]he browser is rapidly becoming the hub of enterprise activity, evolving into the new endpoint for both productivity and threat risk.”
The growth of GenAI and agentic AI –and their subsequent integration into business workflows– are especially concerning, serving as a potential security gap that enterprising threat actors can exploit. Organizations need to evolve their security strategies to better reflect this new way of working by providing context-aware data loss prevention (DLP), AI usage visibility and governance features directly in the browser. This includes AI-driven threat detection and precision controls to counter highly evasive and adaptive threats (HEAT) and AI-powered attacks. At the same time, evolving data privacy laws and regulatory complexity are driving new architectures that differentiate between work and personal activity, enforce granular audit controls and ensure local data custody.
As a result, Frost & Sullivan expects double-digit or even triple-digit year-on-year growth rates in the emerging zero trust browser market. According to the report, the market generated aggregated revenue of $622 million in 2025, and a compound annual growth rate of 18.9% is anticipated from 2025 to 2030.
Menlo Security is uniquely positioned to drive the zero trust browser market. While other vendors offer a mere "wrapper" on a standard browser, Menlo’s high Innovation ranking is tied to its patented Adaptive Clientless Rendering (ACR) technology, HEAT Shield AI, Menlo Browsing Forensics and fine-grained browser controls is central to the company’s leadership and success. According to Frost & Sullivan, this will allow Menlo Security to build the first true AI browser security platform.
Here is the key product strategy decisions that the report highlights:
Menlo Security HEAT Shield AI leverages Google Gemini to provide real-time, in-browser defense against highly evasive web threats like zero-hour phishing, brand impersonation and social engineering. It works by using generative AI tools and deep neural networks to analyze browser activity and block threats before they reach users. It identifies malicious sites by analyzing page elements (JavaScript, DOM, logos) in parallel, dynamically blocks access, sets sites to read-only and integrates with SIEM/SOAR for visibility.
ACR technology enables an agentless approach to browser security where a surrogate browser executes in the cloud rather than on endpoints. This neutralizes threats before they reach users’ devices while maintaining a transparent user experience with unnoticeable latency.
The 2024 acquisition of Votiro significantly expanded Menlo’s data security, adding Content Disarm and Reconstruction (CDR). These tools address the GenAI data leakage concerns that are top-of-mind for CISOs, preventing sensitive data from reaching public large language models.
Menlo Security is aggressively pursuing displacement of legacy VPN and VDI infrastructure by focusing on high-value, compliance-driven use cases. Prioritizing the development of clientless access capabilities for non-web applications (SSH and RDP), privileged remote access scenarios and operational technology environments address critical market gaps. These specialized workloads require the granular, browser-context controls that Menlo’s architecture provides, such as session recording, read-only access and the ability to view and access files in the Menlo Cloud – which are essential for auditability and least-privilege access.
When compared to other market participants, Menlo is recognized as the go-to for threat prevention. While some vendors ask organizations to abandon familiar tools for a proprietary browser, Menlo delivers elite security within the browsers users already know. This heritage in isolation, combined with its shift to a secure enterprise browser solution, has made it the superior choice for large enterprises.
The world is changing, and Menlo Security is highly positioned to help organizations better secure where work overwhelmingly takes place: in the browser. The Frost & Sullivan radar report is validation of this strategy, positioning Menlo Security as a ‘Company to Action’ in 2026 and beyond.
