LayerX announced a $26 million Series A on May 2, 2024, to fund its browser-security platform, which the company describes as an extension that adds security visibility and controls to browsers organizations already use. Glilot+ led the round, with Dell Technologies Capital participating. LayerX said its total investment had reached $34 million at the time.

What LayerX raised—and how its later funding announcement describes it

LayerX’s May 2, 2024 announcement said the company had raised a $26 million Series A led by Glilot+, with participation from Dell Technologies Capital. At that time, LayerX reported $34 million in total investment. LayerX’s 2024 announcement is the source for those figures.

On April 28, 2025, LayerX announced an $11 million extension led by Jump Capital, with continued participation from Glilot and Dell Technologies Capital. The release contains two different funding figures: its headline describes the Series A as $37 million, while its body says total funding reached $45 million. Read together, the figures imply a $37 million Series A—$26 million plus the $11 million extension—and $45 million raised overall. The release does not explicitly reconcile that distinction in its headline. The 2025 release supports both numbers, but $45 million should not be described as the Series A amount.

What the browser-security platform does

LayerX describes its product as a browser extension that works with browsers such as Chrome, Edge, Safari, and Firefox, rather than requiring an organization to replace them with a dedicated enterprise browser. The company says the extension provides real-time visibility into browser sessions and lets security teams apply controls where employees interact with websites, SaaS services, and AI tools.

LayerX lists several intended security uses:

  • Data-loss prevention: monitor or control sensitive information moving through websites and SaaS applications, including AI tools such as ChatGPT and Microsoft Copilot.
  • Browser-extension management: identify and manage extensions that may introduce risk.
  • Shadow SaaS discovery: detect SaaS services employees use without organizational authorization.
  • Safe browsing: block access to malicious or phishing sites.
  • Identity protection: protect identities used to access cloud services.

These are capabilities LayerX describes in its product and funding materials; the cited releases do not provide independent product testing or measured outcome data. LayerX positions its controls as complementary to endpoint, network, or secure service edge (SSE) security, and says organizations may deploy them alongside those tools rather than treating the extension as a replacement for all of them. LayerX’s product description provides the company’s account of its deployment model and use cases.

Who may find the approach relevant

The extension model may interest organizations seeking visibility and policy controls over workforce browser activity without requiring employees to adopt a different browser. The use cases LayerX names are especially relevant to teams concerned about SaaS usage, browser add-ons, sensitive data entered into web services or generative AI tools, and employees working across varied environments.

That description explains the intended role, not proven effectiveness. The available releases do not establish comparative efficacy against a dedicated enterprise browser or network/SSE product, nor do they quantify customer outcomes. Glilot’s account of adoption, traction, and customer satisfaction is investor commentary rather than an independent market assessment. Glilot’s explanation of its investment offers its perspective on the company.

Why LayerX says it raised the money

LayerX presented the financing as support for its browser-security business and its effort to address security risks arising from employee activity in browsers. In the 2025 announcement, CEO and co-founder Or Eshed described the approach as “last-mile user guardrails” intended to avoid the complexity of SSE or the experience changes associated with enterprise browsers. That is the company’s rationale for its product positioning, not an independently verified comparison.
