What Keystile does
Section titled “What Keystile does”Checked before it happens
Each action is allowed, held for a person, or stopped, against your own rules in plain English — whatever app, field or wording the agent uses.
Quality control on what comes back
What apps return to the AI tool is screened too: hidden instructions are caught, client identifiers masked.
Restricted access
Each agent gets only the tools and the task it needs, for as long as it needs them.
Limits and budgets
Payment caps, call limits, and monthly or yearly budgets per group of tools that never go over.
A record you can hand over
Every decision goes into a signed record. Any change to it afterwards is detectable.
Three levels of protection
Section titled “Three levels of protection”Keystile Core
The fixed checks: exact limits, permissions, approvals, budgets, sensitive data, task actions. The same answer every time.
Keystile Insight
Keystile Intelligence: what each action means against your rules, unusual behaviour, hidden instructions, whether it serves the task.
Keystile Fortress
Both together — the highest protection, and the default.
