Opal Security Raises $23M in New Funding Led by Greylock

The round also saw participation from Cambium Capital. The raise brought the total amount to $59M.

The company plans to use the funding to expand its operations and accelerate product development.

Since the beginning of 2026, more than 60% of Opal’s workforce has joined the company, with hiring increasing across engineering, product, and go-to-market teams.

This growth reflects a broader industry trend as AI agents become more common in enterprises, often gaining access to systems faster than security teams can properly monitor and manage.

To address this challenge, Opal helps organizations manage AI agents alongside human users and service accounts within a single access control system. In March, the company launched a platform that provides visibility, governance, and policy enforcement for access management. The platform is powered by Paladin, an AI engine that reviews access requests and only sends complex cases to human reviewers.

Companies such as Databricks, Notion, Cloudflare, Scale AI, CoreWeave, SpaceX, and Superhuman use Opal to improve how they manage access and identity security as they adopt AI agents.

For example, Databricks processes about 86,000 just-in-time access requests through Opal, while Mercari manages more than 5,000 Okta permissions using automated reviews. The goal is to grant access only when needed, regularly review permissions for risk, and remove access as soon as it is no longer required. As AI agents become more common, these controls need to work at much greater scale and speed.

"Great operators don't chase markets—they pick the biggest problem and the best team to solve it with," said Howard Ting, CEO of Opal Security. "Sameer, John, Michael, and Christine have each built category-defining products, and they came to Opal for the same reason: governing access across every identity—human, service, and AI agent—is becoming one of the defining problems in security. The new funding gives us the resources to go solve it."

"I've spent my career in identity and security, and it's rare to see a platform this aligned with where the market is heading in the era of AI," said Sameer Mehta, Chief Product Officer at Opal Security. "Access used to be a one-time decision. Today it's a continuous, high-volume problem across humans, services, and AI agents at machine speed. The real problem is control. Where most solutions stop at visibility or governance, what excites me about Opal is that they're defining the control plane for identity, enforcing access decisions in real time across every system."
