Akamai pays $205 million for LayerX to police enterprise AI usage in the browser

Akamai is buying Israeli browser security startup LayerX for $205 million. The deal, announced Thursday morning, gives Akamai a control layer inside the browser where most enterprise work now happens and where employees interact with generative AI tools, SaaS apps, and agents.

LayerX was founded in 2022 by CEO Or Eshed and CTO David Vaisbrud. The company raised $45 million total, including a $37 million Series A last year at a $62 million valuation. Investors included Jump Capital, Glilot Capital Partners, and Dell Technologies Capital. Akamai is paying more than three times that valuation.

The product sits inside the browser as an extension rather than forcing companies to rip out Chrome or Edge and replace them with some proprietary enterprise browser. That is the key difference. Most competitors in this space want you to migrate your entire workforce to a custom browser. LayerX says no, keep what you have, and we will monitor and control AI usage, file uploads, prompt injections, and SaaS interactions from inside the existing browser.

This matters because 2026 has become the year of unchecked enterprise AI adoption. Employees paste source code into ChatGPT, upload spreadsheets to Claude, and let AI agents browse internal systems. Security teams are flying blind. Mani Sundaram, who runs Akamai’s Security Technology Group, put it plainly: “Their existing controls cannot see how employees are interacting with AI tools and sharing with large language models.”

Akamai is framing this as an AI usage control play layered on top of its Zero Trust portfolio, which already includes ZTNA, runtime protection for AI apps, and workload segmentation for AI inference. The idea is to cover the user, the app, and the infrastructure in one stack.

For LayerX, this is a fast exit. The company is expected to hit only about $10 million in annual recurring revenue by year end. Akamai says the deal will dilute non-GAAP EPS by roughly $0.12 for fiscal 2026. The transaction should close in the third quarter.

This is Akamai’s fourth Tel Aviv-based cybersecurity acquisition in five years. The company has clearly decided that Israel is its primary R&D outpost for security innovation. Eshed and Vaisbrud will join Akamai’s Zero Trust organization along with the rest of the LayerX team.

The broader signal is that the browser is now the main battlefield for enterprise security. Not the endpoint. Not the network perimeter. The browser. If you cannot see what happens inside it, you cannot secure AI adoption. Akamai just paid $205 million to fix that blind spot.
