Glossary
The vocabulary, defined
The terms that recur across the platform and the documentation, written for everyone on the buying committee, technical or not.
Terms, in plain language
Each entry is anchored, so you can link straight to the one you need.
- Sentinel
- The lightweight component on each device that governs AI traffic and enforces policy at the point of use.
- Agent
- An AI system that can take actions on its own, such as a coding assistant that reads files or calls tools. Verillian governs what an agent can do the moment it acts, the same way it governs a person's AI tool.
- Admin server
- The central component for policy distribution, audit storage, fleet management, and reporting.
- Chain
- An append-only sequence of signed entries where each depends on the one before it, so any change is detectable.
- Chain entry
- A single signed record of one intercepted interaction, with timestamp, decision, and a hash linking it to the prior entry.
- Intercept
- Capturing AI traffic on the device, before it reaches a provider, so policy applies while the data is still inside the boundary.
- Policy
- The institution's rules for what AI tools may do, evaluated at the tool and argument level at the moment of execution.
- Provider
- The downstream model service an AI tool reaches, such as Anthropic, OpenAI, or Google.
- Decision
- The outcome of a policy evaluation: allow, redact, or block. Every decision is signed into the chain.
- Fail-closed
- The rule that AI traffic stops when there is no valid policy or the audit pipeline fails. Unaudited AI is a stop condition.
- Opaque-ciphertext server
- A server that stores encrypted audit content it cannot read. Decryption requires the institution's key.
- Non-repudiation
- The property that an entry's origin cannot be denied, because it is signed by a device key the server cannot forge.
- Redaction
- Removing sensitive content from an outbound request before it reaches the provider.
