Cyera and Oasis: Stronger Together

Danny, Amit, Yotam, Tamar, Yonatan and their teams are joining forces to build a complete security platform for the age of AI.

In 2021, before Oasis Security was even founded, I sat down with co-founder Danny Brickman and came away thinking he had something familiar. He showed the same drive we’d seen in the founders of two other Sequoia companies, Wiz and Cyera, whose founders, like Danny, had come up through Talpiot, the leadership program of the IDF. I wrote about that meeting a couple of years later in my investment memo, when we Oasis Security, at the Series A. I didn’t realize at the time how literally connected that comparison would turn out to be. Today, Oasis is joining Cyera — and it turns out the founders’ stories make the case for this combination almost as well as the technology does.

Three years ago, the pitch for Oasis was simple: enterprises were about to have far more machine identities than human ones, and almost nobody had a real way to manage or secure them. That was true then. It’s far more true now. Every AI agent creates or uses non-human identities — API keys, service accounts, OAuth tokens, agent-to-agent credentials — that act with real permissions and real blast radius, and that don’t behave anything like the human identities the last generation of identity tooling was built around. AI drove non-human identity from a niche IAM subcategory to a board-level CISO conversation. Danny Brickman and his co-founder Amit Zimerman built Oasis, which they call agentic access management, for exactly that world.

Cyera arrived at the same shift from a different direction. Yotam Segev, Tamar Bar-Ilan, and Yonatan Itai built the company to answer a deceptively simple question: where does an organization’s sensitive data actually live, who can reach it, and what’s really at risk? As AI agents started reading, writing and acting on that data, they reached a conclusion that now looks obvious: securing AI means securing the data, the identities acting on it (human and non-human), and the agents themselves.

Put the two products side by side, and they complement each other perfectly. Cyera knows where the sensitive data is. Oasis knows who or what can actually touch it — every service account, API key and agent credential, and whether it’s behaving the way it should. It’s a bit like a bank vault: the best way to protect it is by knowing both what’s inside and who’s approaching. Data security tells you what’s actually at stake. Identity security tells you whether the thing touching your data is legitimate. Together, the two products cover the entire path an AI agent takes through a company’s environment, from the data it touches to the identity it uses to touch it.

There’s a practical case here too. Cyera has built one of the most powerful enterprise GTM teams, with the kind of scale that usually takes a startup a decade to reach. Oasis’s product now gets to run through that engine, into enterprise accounts it would otherwise have taken years to earn on its own. And the market isn’t waiting: Whoever builds the first genuinely complete AI security platform, spanning data, identity and agents, has a real shot at becoming the default layer enterprises standardize on as agentic AI rolls out. Speed and completeness both matter, and the combination of Cyera and Oasis creates both.

The founders’ backgrounds make the fit feel almost inevitable in hindsight. It’s a small world: two teams we’d backed independently, drawn from the same pool of Israeli technical talent, ended up building the two halves of the same answer to AI security. Talpiot and Unit 8200 alumni have produced a disproportionate share of the last decade’s big cybersecurity companies, so the coincidence is smaller than it looks, but it’s still a good sign when it plays out this cleanly.

Danny, Amit and the Oasis team built the category-defining company in non-human identity in under three years, from a standing start to a product enterprises trust with agentic access at scale. That doesn’t happen without genuinely hard technical work, and a founder team that saw the shift to agentic AI before almost anyone else in security did. We at Sequoia have backed both Cyera and Oasis since their Series A rounds, and we’re proud to keep backing this team as they take on the next chapter together — a bigger stage, and an opportunity sized to match.
