Akamai Set to Enhance Security with LayerX Acquisition for $205 Million
In a strategic move to bolster its cybersecurity framework, Akamai Technologies has announced its intention to acquire LayerX, a rising startup specializing in browser security. This acquisition, valued at $205 million, aims to strengthen access decisions by enhancing visibility and control during user interactions, particularly in contexts involving artificial intelligence tools and cloud applications.
The Boston-based cybersecurity leader pointed out that this acquisition aligns perfectly with Akamai’s commitment to its zero trust network architecture and segmentation products. According to Mani Sundaram, the Executive Vice President of the Security Technology Group at Akamai, the browser serves as a critical interface where employees actively engage with AI tools. He stated, "The secure browser perspective is essential, as it observes user interactions right from the source level. This pre-decryption approach ensures that applications remain intact while providing enhanced security."
Founded in 2021, LayerX has quickly positioned itself as a promising player in the cybersecurity realm. The startup, headquartered in Tel Aviv and led by CEO Or Eshed—who has an extensive background in cybersecurity from his time as a threat intelligence analyst at Check Point and his service in the Israeli Defense Forces—has raised $45 million over two funding rounds. The recent $11 million Series A extension was spearheaded by Jump Capital in April 2025, underscoring LayerX’s growing potential and market relevance.
The Growing Importance of Browsers in AI Interaction
As organizations grapple with the complexities surrounding AI, the role of web browsers has become increasingly pivotal. Many firms are unclear about the data being uploaded to AI systems and how employees interact with these tools. This uncertainty can lead to potential risks regarding the exposure of sensitive enterprise information through AI-related activities. Sundaram highlighted a growing concern among Chief Information Security Officers (CISOs) regarding the risks associated with employee engagement in AI environments. He noted, "Conversations with many CISOs reveal their worries about data exfiltration and how employees are interacting with AI technologies."
Eshed also noted that web browsers are now the primary operating environment through which users access AI systems, copilots, and Software as a Service (SaaS) applications. Presently, 80% to 90% of user activity related to AI occurs within these browser settings. This shift positions browsers as key strategic areas for applying visibility, policy enforcement, and monitoring user behavior.
With the rise of intelligent agents capable of performing tasks autonomously—such as file creation and data transfer—organizations face entirely new security challenges. These agents operate outside the behavioral norms associated with human users, necessitating a rethinking of traditional security controls. As Eshed observed, "The behavior of agents deviates from predictable human actions, creating unexpected security challenges." Understanding what these agents do in user spaces is, therefore, becoming a critical facet of enterprise security.
Enhancing Security Cooperation Between Layers
The integration of browser security features complements other security mechanisms, such as Zero Trust Network Access (ZTNA) and micro-segmentation. Sundaram explained that browser security supplies additional behavioral signals about user actions and session activities, which can inform Akamai’s access control engines. This context enables more nuanced decisions regarding access permissions—whether to allow, restrict, or terminate access—based on real-time behavior assessments.
Eshed suggested that even with unlimited budgets, companies must rationalize their investments in security tools. He emphasized that AI solutions are increasingly becoming essential for every platform, making the need for validated investments even more acute.
The layered security approach positions browser security as the initial interaction layer at endpoints. In contrast, ZTNA manages north-south traffic between users and applications, while micro-segmentation safeguards east-west traffic among servers, workloads, and databases. Akamai’s integrated framework aims to ensure comprehensive security throughout the communication chain, from the endpoint to the backend infrastructure.
"A web browser serves multiple functions," Sundaram explained, "like confirming if a user is authenticated within an app, monitoring user activity, and assessing the nature of the content accessed. This multifaceted approach feeds into the ZTNA framework, which allows for granular control over user actions."
Akamai is committed to maintaining LayerX as a standalone offering while integrating key functionalities into its broader enterprise security suite. As the company moves forward, it anticipates merging browser security with ZTNA, segmentation, and AI governance into a cohesive security solution. Success metrics will reflect account penetration performance, annual recurring revenue growth, and enhanced adoption rates of bundled solutions.
In closing, Sundaram noted the transformative influence of AI on the security landscape. "AI is fundamentally altering the field, and we aspire to lead the way in providing robust security in a post-AI environment," he asserted. The growing complexity and potential threats associated with AI implementations continue to be a primary concern for CISOs globally, emphasizing the need for innovative security measures moving forward.
