Varonis is pulling the plug on on-prem. ProLion isn’t.

Your copilot does not break in. It is invited.

An AI agent answers with the permissions of whoever asks it. Every broken ACL and every share that quietly resolves to Everyone becomes a correct, well-formatted answer — no attack required.

NetApp

Syslog CEF and REST, into the tool you already run

Why this is new

The permissions were always wrong. Search just made it matter.

EMPLOYEE PROMPT“What are we payingthe new hires?”AGENTWHAT IT MAY READ BACK, AS THAT PERSONfinance/salaries/shared with EveryoneEVERYONEprojects/alpha/your teammarketing/assets/your teamarchive/2019/read-onlyhr/payroll/inherited from the folder aboveINHERITEDlegal/m&a/permissions never appliedBROKEN ACL3 of 6 are reachable only by accident

No attack took place. The agent answered with the rights the asking user already had.

Obscurity was the control

Finding a misfiled salary spreadsheet required knowing it existed. Semantic search removed that protection in one quarter.

The model is not the problem

Guardrails do not change what the agent is allowed to read. Fix the data layer, not the prompt.

Agents are a new identity

An agent acts continuously, at machine speed, with delegated rights. An annual access review does not describe it.

This is the part a cloud platform cannot do for on-premises data without first copying it somewhere else — which is the problem you were trying to solve.

Sovereign by construction

AI-safe and sovereign are the same project.

For a hospital, a utility or a public authority, the fastest route to trusted AI is not a bigger model. It is knowing what the model can see — proven on infrastructure that never leaves the jurisdiction it answers to.

Three questions before an AI rollout
  • Which sensitive files can the agent reach today?
  • Which of those permissions are accidents?
  • Can you show an auditor what it read last month?
