SentriAI vs Witness AI
Witness AI observes and governs how people use AI. SentriAI governs the actions AI agents take. Here is the honest comparison.
TL;DR verdict
Witness AI is an AI security and governance platform that gives visibility into and control over how employees use AI applications. SentriAI is an AI Action Governance platform: it decides, per action and at runtime, whether an actor should be allowed to do a thing to a resource - and records the verdict as tamper-evident evidence. These solve different problems, and for most teams they are complementary rather than either-or.
What Witness AI does well
- Visibility into which AI apps employees use and how
- Controls on data going into third-party AI tools
- Policy enforcement on employee GenAI usage
- A focus on the human-to-AI usage layer
Where SentriAI differs
Witness AI governs the human-to-AI usage layer - which apps people use and what data they paste in. SentriAI governs the AI-to-system action layer - what an agent does once it acts. Usage visibility answers "who is using what AI"; action governance answers "should this action the AI is taking be allowed". They meet in the middle and reinforce each other.
What SentriAI adds that this category does not
- A per-action Policy Decision Point that returns allow, step-up, review, contain, or deny
- An Action Trust Score (0–100) with the explainable factors behind it
- A hash-chained, reproducible trust ledger for every decision
- Governed actions that map themselves to SOC 2 CC6/CC7 and other controls
Side-by-side
| Dimension | SentriAI | Witness AI |
|---|---|---|
| Primary job | Govern AI-to-system actions | Govern human-to-AI usage |
| Layer | The agent’s action on a system | Employee AI app usage |
| Runtime enforcement | Yes - per-action verdicts | Usage controls |
| Agent action gating | Core | Usage-centric |
| Evidence model | Governed-action evidence | Usage and DLP events |
| Best fit | Governing agent actions | Governing employee AI usage |

Frequently asked questions
Is SentriAI a Witness AI alternative?
They govern adjacent but different layers. Witness AI governs how employees use AI apps; SentriAI governs the actions AI agents take on your systems. Together they cover both the human-to-AI and AI-to-system directions.
Does SentriAI monitor employee AI usage?
That is not its focus. It governs the actions agents take, including data-touching actions, but it does not specialize in observing which AI apps employees use the way a usage-governance platform does.
How do they complement each other?
Use a usage-governance platform to control what employees put into AI tools and SentriAI to govern what AI agents then do on your systems - two ends of the same AI risk.
Which governs autonomous agents?
SentriAI. Autonomous agents acting on systems are its core, whereas usage-governance tools center on the human-to-AI interaction.
