New York – September 28, 2026 -- Noma Security has expanded its AI and agent security platform to cover autonomous agents, MCP servers, and skills running directly on employee laptops, closing what the company calls one of the largest blind spots in enterprise AI security.
Agents on employee machines inherit full user credentials without oversight
Coding agents such as Claude Code, Cursor, Codex, and Windsurf, along with productivity agents like Claude Cowork, already operate on employee devices with the same permissions and credentials as the humans who installed them. MCP servers and skills extend that access into databases, repositories, and internal systems, often chaining actions across a session without requiring approval at each step.
Grok Build case shows agents can exfiltrate data even when explicitly told not to
A security researcher found that xAI's Grok Build coding assistant uploaded entire tracked repositories and their full Git history to the provider's cloud, despite being explicitly instructed not to open any files. Noma cites the incident as evidence that approving an agent is not sufficient protection; enforcement must operate while the agent is actively working.
Platform adds governed registry, identity-aware policy, and tool-level control
Noma's new Access Control capability connects through existing EDR or MDM infrastructure to build a live inventory of agents, MCP servers, skills, and connected accounts across managed devices. Every discovered asset receives a status of approved, needs review, or blocked, and is attributed to the individual user and linked to IdP groups. Policies can be set at the level of the agent, tool, or specific action, allowing read access to remain broad while create, update, or delete operations stay restricted to smaller groups.
AI-DR layer monitors sessions in real time to detect drift and data leakage
Noma's AI Detection and Response (AI-DR) layer establishes behavioral baselines for each agent and flags prompt injection, sensitive data leakage, tool poisoning, scope violations, and behavioral drift. Contextual Policies correlate prompts, tool calls, responses, and identity data across full sessions to catch threats built from sequences of individually permitted actions. Each detector can be tuned to monitor, alert, block, mask data inline, or escalate to a human reviewer.
CEO says privileged endpoint identities have gone largely unmonitored
"Agents on the endpoint carry some of the most privileged identities in the company, often unnoticed by security until something goes wrong," said Niv Braun, CEO and Co-Founder of Noma Security.
Deployment spans agent hooks, gateways, SDKs, and hundreds of tuned policies
Noma Open Enforcement applies across agent hooks, AI and MCP gateways, SDKs, and EDR/MDM systems, covering agents including Claude Code, Claude Cowork, Cursor, Codex, Windsurf, Kiro, Antigravity, and OpenClaw. Organizations start with hundreds of AI-DR policies and protection profiles tuned by industry and agent type, drawn from work with dozens of Fortune 500 security teams. Noma also plans to extend its Agent Boundaries feature, which enforces business-defined action limits, to endpoint devices.
