Akamai Snaps Up AI Browser Security Startup LayerX for $205 Million to Fortify Zero Trust

Akamai Technologies has agreed to acquire LayerX, an AI-powered browser security startup, for $205 million in cash, the company announced today. The deal is expected to close in the second quarter of 2025, pending regulatory approvals.

The acquisition dramatically expands Akamai’s Zero Trust portfolio by adding direct protection inside the browser, a critical attack vector as remote work persists. LayerX’s platform uses machine learning to detect and block malicious activity at the browser level, preventing credential theft, data exfiltration, and phishing attacks.

“This is a game-changer for enterprise security,” said Tom Leighton, CEO of Akamai, in a prepared statement. “By embedding our Zero Trust capabilities into the browser, we can stop threats before they reach the endpoint.”

Background

LayerX, founded in 2021, has raised $30 million in venture capital and counts several Fortune 500 companies among its customers. The startup’s browser isolation and AI threat detection technology complement Akamai’s existing edge security and Zero Trust offerings.

Browser security has become a hot market, with Gartner predicting that 60% of enterprises will adopt some form of browser isolation by 2027. Competitors include Menlo Security, Netskope, and Zscaler, but Akamai’s massive content delivery network gives it a unique distribution advantage.

“LayerX fills a clear gap in Akamai’s security stack,” said Sarah Chen, principal analyst at Forrester Research. “Browser attacks are skyrocketing, and traditional solutions like VPNs and endpoint detection are insufficient. This acquisition positions Akamai as a leader in the emerging browser security category.”

What This Means

For Akamai, the deal signals a strategic pivot toward applying AI at the browser level, shifting security controls closer to user activity. The company can now offer a unified platform that protects users across web, cloud, and private applications without requiring client software.

For customers, the result is simpler deployment and stronger protection. LayerX’s browser extension can be deployed in minutes, and its AI models continuously adapt to new threats. “This is exactly what CISOs have been asking for: a way to protect remote workers without slowing them down,” noted Mike Walters, vice president of product management at Akamai.

The acquisition also intensifies competition in the Zero Trust market, where incumbents like CrowdStrike and Palo Alto Networks are racing to add browser security. Akamai’s existing relationships with thousands of enterprises give it a ready-made distribution channel for LayerX’s technology.

Financial terms beyond the $205 million purchase price were not disclosed. Akamai expects the deal to be neutral to earnings per share in fiscal 2025 and accretive thereafter.

LayerX’s team of about 40 employees, including founder and CEO Or Katese, will join Akamai’s security division. “We built LayerX to stop browser-based attacks at machine speed,” Katese said. “Joining Akamai lets us bring that capability to the global scale it deserves.”
