From invisible shadow AI to real-time protection and audit-ready evidence.
The problem
AI is already working with your business data. Are you still in control?
Shadow AI is spreading. Agents access data, call tools and trigger spend. Policies written for humans can’t govern machine decisions. Qastel turns your business rules into controls enforced at runtime, even on AI tools IT never approved.

How Qastel works
Define your AI policies once. Enforce them everywhere.
Qastel turns regulatory requirements and the business rules unique to your organization into controls enforced wherever AI operates.
- 01
Business & regulatory requirements
Bring together external obligations, such as the EU AI Act and DORA, with the internal rules that define how your business wants AI to operate.
- 02
Policies
Translate those requirements into clear policies: which data may reach which AI tools, and which tools are approved.
- 03
Runtime enforcement
Enforce policies wherever AI is used: across browsers, desktops, agents and MCP gateways, including AI tools IT never approved.
- 04
Continuous evidence
Track policy decisions, exceptions and changes, with evidence you can use for internal governance and regulatory compliance.
For every team
Built for domain experts, not just IT.
The people who know where the risk sits write the rule. HR, Finance, Legal, Compliance, Sales and Engineering describe it in their own words, and Qastel turns it into a policy.
- Policies written in your own words
- Reviewed before anything goes live
- Enforced in the browser, on the desktop and at the MCP gateway
From HR: “Block employee personal data from any AI tool we have not approved.”
- When
- Employee personal data is sent to an AI tool
- Unless
- The tool is sanctioned
- Then
- Block, and notify the HR lead
- Applies to
- All AI tools · all employees
