There are moments in the evolution of any technology category when the rules change fast enough that standing still means falling behind. The rise of agentic AI is one of those moments for Identity Security, and it’s one we’ve been preparing for.
It has driven some of the milestones I’m most proud of from the past year alone. We deepened our relationships with some of the world’s biggest enterprises, who trust us to protect their most critical infrastructure in the agentic era. We launched multiple new products, including our AI Agent Security product, making Silverfort the broadest Identity Security platform in the market, and one of the first to bring real visibility and runtime controls to the identities powering AI agents. And we were recognized as a sample vendor in the Gartner® Market Guide for Guardian Agents, an acknowledgement that reflects how far ahead of the curve our team has been thinking.
Each of these moments reflects the trust our 1,000+ customers place in us, and the role we’ve taken as leaders in the Identity Security market. We’ll never take either lightly.
Today, I’m proud to announce our next chapter which will soon reshape the Identity Security space: Silverfort is acquiring Fabrix Security.
Why Fabrix Security and why now
The agentic era is here, and it has exposed a fundamental gap in how identity and access works.
For decades, Identity Security and access control have operated on a simple but increasingly inadequate model: define rules at “admin time”, grant access in advance, and review what went wrong after the fact. That approach was already showing its limits with human users, but with non-human identities and AI agents, it breaks entirely.
There’s a harder truth here, too. An Identity Security posture built on rules written at admin time simply will not work against AI-driven threats. Every day, new AI models such as Anthropic’s Mythos prove that this has gone from a theoretical to an actual, evolving risk. AI agents are becoming more difficult to control. Adversaries can now use AI to run complex attacks and exploit stolen identities and over-privileged access, often in a matter of seconds.
The only way to meet this challenge is to fight AI with AI by deploying precise, runtime decisioning and enforcement when and where it matters. We need to make Identity Security and access control autonomous, continuous and dynamic enough to handle the scale and speed of agentic AI.
That’s exactly what Fabrix Security and Silverfort will make possible together.
Fabrix Security: The AI decisioning engine for Identity Security
The Fabrix team built an AI-native decisioning engine that leverages a rich knowledge graph with data about identities, permissions, intent and business context. It enables them to make intelligent, real-time authorization decisions, including Just-In-Time access, without slowing the business.
What impressed me most was not just the technology, but the team behind it. CEO Raz Rotenberg was a founding engineer at Run:ai, acquired by Nvidia. CTO Ofir Yakovian was a tech lead at Orca Security and Microsoft Entra, and holds an M.Sc. in quantum computing. VP of R&D Roee Oz was chief architect for Microsoft Defender for Cloud and led Microsoft’s AI security incubation.
They and their exceptional team bring rare depth across AI, security and identity, and I couldn’t be more excited to welcome them to Silverfort.
What we’re building together
Silverfort pioneered Runtime Access Protection, which enforces access decisions inline to control what any human, machine, or AI agent can access across on-prem and cloud environments. What we’re adding with Fabrix Security is an AI-driven decisioning engine that can determine access controls at the moment they are needed, using real-time context.
Raz puts it best: “By joining Silverfort, we can combine our technology with Silverfort’s platform to create something no one has achieved before: autonomous runtime Identity Security. Together, we’ll be the first to bring to the market this next generation of Identity Security—one that can truly stand up to AI-driven adversaries without slowing the business.”
What comes next
We’re moving quickly to bring these capabilities together into a unified offering. Our teams are already aligned on the vision, and we are aiming for our customers to be able to benefit from these capabilities in the second half of 2026.
To our customers, partners, investors, and the extraordinary Silverfort team: thank you for continuing to push our mission forward. The pace of change in our industry is only accelerating, and we are more ready than ever to meet it.
To the Fabrix Security team: welcome! We are so glad you’re here. Let’s build the future of autonomous Identity Security together.
