Silverfort Inc. announced on April 28, 2026 that it has acquired Fabrix Security, a Tel Aviv‑based AI‑native identity‑security startup. The deal merges real‑time AI decision engine with Silverfort’s Runtime Access Protection (RAP) platform, creating what the companies call the first autonomous Identity Security solution capable of protecting human, machine and emerging “agentic” identities at the speed of modern workloads.
What the Deal Entails
The acquisition brings Fabrix’s knowledge‑graph‑driven authorization engine under Silverfort’s umbrella. Fabrix, founded by former Run:AI and Microsoft Entra engineers, raised $8 million from investors such as Norwest and toDay Ventures. Its technology can evaluate millions of access requests per second, scoring each request against contextual signals like intent, device posture, and business relevance. Silverfort contributes a proven RAP layer that enforces decisions at the point of execution across on‑prem, cloud and SaaS environments without requiring agents on every asset.
Financial terms were not disclosed, but the combined entity now serves more than 1,000 enterprise customers, many of whom are already piloting the joint solution. The integration is slated for a phased rollout, with core capabilities expected in the second half of 2026.
How the Combined Technology Works
At the heart of the new platform is an AI‑driven authorization engine that builds a dynamic identity knowledge graph. When a user, service account, or AI‑powered bot attempts to access a resource, the request is streamed to the graph, which enriches it with real‑time data—role assignments, recent activity, risk scores, and even the purpose of the request. A lightweight machine‑learning model then produces a “allow”, “deny” or “challenge” decision in milliseconds.
Silverfort’s RAP layer intercepts the request at the runtime layer—whether it’s a database query, an API call, or a cloud function—and enforces the AI‑generated decision instantly, without waiting for a separate policy engine. The enforcement point is embedded directly in the execution path, ensuring that even short‑lived, serverless functions are covered.
The architecture supports a hybrid “human‑in‑the‑loop” mode: high‑confidence decisions are automated, while borderline cases can trigger alerts for security analysts or be reviewed by an AI‑assistant. This balances speed with governance, a crucial need for regulated industries.
Why It Matters for Enterprises
Speed vs. risk – Gartner predicts that by 2027, 70 % of security breaches will involve compromised service accounts or AI agents. Traditional static policies, which are updated on a weekly or monthly cadence, cannot keep pace with the sub‑second decision cycles required by modern workloads. An autonomous, runtime‑driven approach reduces the window of exposure from minutes to milliseconds.
Scale of agentic identities – IDC estimates that the number of non‑human identities in enterprise environments will triple by 2028, driven by micro‑services, containers and generative‑AI assistants. Fabrix’s graph can ingest and correlate billions of identity events, giving security teams visibility that was previously impossible.
Cost efficiency – Forrester’s “Zero‑Trust Index” (2023) shows that organizations using continuous, context‑aware enforcement reduce average identity‑related incident costs by 45 %. By consolidating policy creation, decisioning, and enforcement into a single platform, Silverfort‑Fabrix promises lower operational overhead and fewer false positives.
Regulatory compliance – Real‑time enforcement helps meet stringent data‑privacy mandates (e.g., GDPR, CCPA) that require “purpose‑limited” access and immediate revocation when risk is detected.
Implications for Marketing Teams
Enterprise marketers increasingly rely on AI‑generated content, personalization engines, and automated campaign bots. These “agentic” identities often need privileged access to CRM systems, data lakes, and analytics platforms. The new autonomous security platform offers:
- Dynamic permissioning – marketing automation tools can request elevated access for a specific campaign and be granted it for the exact duration needed, then automatically revoked.
- Reduced friction – Real‑time approvals eliminate bottlenecks where IT must manually provision service accounts for new tools.
- Auditability – Every AI‑driven action is logged with context, simplifying compliance reporting for campaigns that handle personal data.
By automating identity risk controls, marketing teams can experiment faster while staying within governance boundaries.
Market Landscape
The identity security market is projected by Gartner to reach $23 billion by 2027, driven by the surge in cloud adoption and AI‑enabled workloads. A recent Forrester Wave (2024) placed autonomous, runtime‑based solutions in the “Leader” quadrant, highlighting their ability to address the “attack surface inflation” caused by micro‑services and generative AI.
Key trends shaping the space include:
- Zero‑Trust convergence – Organizations are moving from perimeter‑based models to continuous verification of every request.
- AI‑augmented risk scoring – Machine‑learning models that incorporate behavioral biometrics and threat‑intel feeds are becoming standard.
- Policy‑as‑Code – Security policies are being codified and version‑controlled, enabling rapid iteration and auditability.
Silverfort‑Fabrix’s platform directly aligns with these trends, offering a unified policy‑as‑code framework powered by AI, with enforcement baked into the runtime layer.
Top Insights
- Runtime AI decisions cut breach response time from minutes to milliseconds, slashing potential damage.
- Agentic identities will triple by 2028; only graph‑based, real‑time solutions can keep them in check.
- Silverfort’s agentless enforcement works across on‑prem, cloud and SaaS, giving it a universal edge over siloed competitors.
- Marketing automation can now request, receive, and relinquish privileged access without human ticketing, accelerating campaign rollout.
- The combined platform is set for a phased release in H2 2026, targeting enterprises already using Silverfort’s RAP.
