Your AI agents trigger payments, query databases, sign contracts, and delegate work to others, often with unchecked permissions.
Xybern intercepts every action and returns a clear authorize or deny verdict before execution.

NVIDIA Inception
Agents trigger payments, query production data, and delegate to other agents, with no permission boundaries and no checks before execution.
Regulator asks "Who authorised this?", no cryptographic proof, no delegation chain, major compliance exposure.
Every action is intercepted and decided before it runs
Delegations are scoped, time-bound, and cryptographically chained
Only permitted actions succeed; everything else is denied
Every decision creates immutable, tamper-evident proof in the Provenance Vault
The Authorisation Layer is the infrastructure. Authorised Agents are the agents we built on top of it. The Provenance Vault holds the signed proof of every decision. Redact strips PII across all of it.
Agents that arrive with their authority declared.
Skills, automations, and connectors, each carrying a permission scope that is enforced before it touches anything.
Every action authorised or denied before it runs.
Intercept, Identify, Authorise, Decide, Record. Any model, any framework, any agent, including the ones you did not build.
Signed, tamper-evident proof of every decision.
SHA-256 hash chains, HMAC signatures, authorisation receipts, and shareable proof packs anyone can verify offline.
Xybern Redact runs across every layer, stripping PII from prompts before they reach a model and restoring it on the way back. Learn more →
5 stages. Every agent action. No bypass.
Intercept
Sits between your agents and your infrastructure. Nothing reaches production without passing through first.
Identify
Every agent carries a cryptographic identity. Xybern verifies exactly who is acting and under what context, no ambiguity, no spoofing.
Authorise
The action is checked against your policy engine. Versioned rules define precisely what each agent can and cannot do.
Decide
A binary authorize or deny verdict. No scoring, no thresholds, deterministic and traceable to the exact policy clause.
Record
Every verdict is written to the Provenance Vault with a cryptographic signature and hash chain. Immutable from the moment it's written.
Framework-agnostic. Model-agnostic. Works with CrewAI, AutoGen, LangGraph, and any custom multi-agent system.
An open, reproducible benchmark of 137 attack and legitimate scenarios, drawn from OWASP, MITRE ATLAS, and CWE. The authorisation layer caught every unsafe action and blocked no legitimate one. A keyword guardrail cannot.
Score is Youden's J (attacks caught minus false alarms). Blocking everything also catches every attack, which is why false alarms matter just as much.
Rephrase the same attacks and a keyword filter collapses from 84% to 44% caught. The authorisation layer stays at 100%, because it judges intent, not keywords.
Every decision is anchored here with tamper-evident records, ready for EU AI Act, SEC, HIPAA, and internal audits.
Each record is cryptographically linked to the previous one. Alter anything and the chain breaks, immediately detectable.
Every record is signed. Authenticity is independently verifiable without trusting the storage layer.
Disclose individual records selectively, proving a specific decision was made without exposing the full audit trail. Exactly what regulatory review and litigation hold demands.
Any model, any agent, any framework. Xybern does not replace your AI systems, it authorises them. Deployable in under one week per workflow.
Model A
Embedded
Integrates directly into your AI platform stack. Each agent receives a cryptographic identity that travels with every action it takes.
Model B
Centralised
Deploys above your existing AI infrastructure without replacing any models or systems. Governs internal LLMs, copilots, workflows, and customer-facing AI from a single layer.
Every other agent platform adds governance after the fact. Authorised Agents are built on the authorisation layer from day one, every action authorised before it executes, by design.
Custom skills define any capability the agent should have. Build once, reuse across agents. Every skill runs under the authorisation layer before it touches anything.
Schedule and trigger agent workflows. Automations pause at high-stakes steps and wait for an authorisation verdict before the next action executes.
Google Drive, Gmail, iManage, SharePoint, and every tool in your stack. Each connector carries a declared permission scope enforced by the authorisation layer, before any data is accessed.
When an AI agent makes an unauthorised decision in your industry, the cost is not a rollback. It's a regulatory event.
