SentriAI vs Cranium
Cranium works on AI/ML security and supply-chain visibility. SentriAI governs the AI action at runtime. Here is the honest comparison.
TL;DR verdict
Cranium is an AI/ML security platform focused on visibility into AI systems, their supply chain, and their exposure. 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 Cranium does well
- Visibility into the AI/ML systems and pipelines an organization runs
- AI supply-chain and exposure mapping for model risk
- Helps security teams inventory and understand AI attack surface
- A focus on the specific risks of machine-learning systems
Where SentriAI differs
Cranium maps and secures the AI attack surface - what models and pipelines exist and how they are exposed. SentriAI governs what those AI systems do when they act. The AI-BOM in SentriAI overlaps on inventory, but the core difference is enforcement: SentriAI decides and gates the live action, not just the exposure of the system behind it.
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 | Cranium |
|---|---|---|
| Primary job | Decide + govern AI actions | AI/ML security visibility and supply chain |
| Unit of control | The individual action | The AI system and its exposure |
| Runtime enforcement | Yes - per-action verdicts | Visibility and posture |
| AI inventory | AI-BOM, reconciled at runtime | Core strength |
| Evidence model | Governed-action evidence | Exposure and risk findings |
| Best fit | Governing AI actions at runtime | Mapping AI attack surface |
Who should pick which
Frequently asked questions
Is SentriAI a Cranium alternative?
They overlap on AI inventory but diverge on enforcement. Cranium emphasizes AI/ML security visibility and supply chain; SentriAI emphasizes governing the AI action at runtime. The AI-BOM gives SentriAI an inventory too, but its core is the per-action decision.
Does SentriAI map my AI supply chain?
It inventories the models, agents, tools, and dependencies your agents rely on in the AI-BOM and reconciles them against what is actually acting to surface shadow AI. A dedicated AI security platform may go deeper on exposure mapping; SentriAI’s emphasis is governing the resulting actions.
How do they complement each other?
Use AI security visibility to understand exposure and use SentriAI to govern and record what the AI systems do, so a mapped risk is backed by runtime enforcement.
Which stops an unsafe AI action?
SentriAI. Governing and gating the live action is its purpose, whereas an AI security posture platform focuses on visibility and exposure.
