Sort the market before you shortlist
Most shortlists in this category are assembled from a search result and end up comparing products that answer different questions. The sorting question is short: does this product describe what your AI systems are, or decide what they may do?
- AI inventory and registry tools catalogue what exists: discovery, ownership, risk classification and a record of what was assessed when.
- GRC and policy suites assess AI systems, document the controls and produce attestations, mapping what you run to a framework and generating evidence for review.
- Runtime enforcement platforms govern what agents do while they run, deciding whether a proposed action executes and holding the credential away from the agent.
- An enterprise may need two when it needs both an inventory and action-time control. The waste to avoid is buying two products from the same group.
AI inventory and registry tools
This is Credo AI's own starting point, and if the registry is what you need, staying is often the right answer. Its product page, fetched on 2 September 2026, describes an AI registry with discovery, risk intelligence, a compliance and policy engine carrying framework packs, a governance assistant called GAIA, a runtime governance module built on trace ingestion, and a module named Agent Governance. The category earns its keep when nobody can currently answer how many AI systems the organisation runs, or who owns them.
One detail that blurs the line
Credo AI describes enforcement integration with CI/CD pipelines, cloud access security brokers and API gateways as planned. If that ships, this group stops being cleanly separable from runtime enforcement platforms, at least for Credo AI. Check its status yourself rather than relying on this page in six months, because it is the fastest-moving fact in the comparison.
GRC and policy suites
This group assesses AI systems, documents the controls and produces the attestations, and it is where an AI programme usually meets an existing enterprise risk function. Two examples are IBM watsonx.governance and Holistic AI.
- IBM watsonx.governance: model inventory, monitoring for bias and explainability, and coverage that reaches across IBM technologies and third-party platforms. Its Q1 2026 update added Agent Monitoring and Insights, which tracks agent decisions and behaviour in production with threshold alerts.
- Holistic AI: the same assessment job approached through automated testing. More than 100 automated tests for bias, hallucinations, red teaming and adversarial probes, compliance mapping to the EU AI Act, NIST AI RMF and ISO/IEC 42001, plus continuous monitoring for drift and shadow AI discovery.
- What neither publishes: a claim to refuse an agent's action before the target system changes.
A caveat on the IBM detail
IBM's product page would not load for us on 2 September 2026, returning 404 and then 403, so the Q1 2026 capability comes from search results rather than from IBM. Verify it with IBM before it goes in a business case. What survives either way is the distinction between monitoring with alerting, which describes behaviour after the fact, and refusing an action before it commits.
Runtime enforcement platforms
This group exists because agents changed the problem. An agent chains steps, picks tools and calls systems without a person confirming each move, so the question stops being which AI systems exist and becomes what this one is allowed to do right now. Products here hold the credential away from the agent, evaluate a proposed action against a policy, refuse or escalate it, and record what happened. Identity vendors also appear around this group, though they solve a narrower slice: identity and access for agents rather than the whole governed run.
The question that sorts any vendor in five minutes
Whatever the category label on the website, ask this set and the group becomes obvious.
- Where does your product sit when an agent calls a tool: in the path of the call, or reading a trace afterwards?
- Who holds the credential for the target system during that call?
- Can the product refuse an action, and can you show me a record of a refusal?
- What is generally available today, and what is roadmap?
- Which of the OWASP agentic risk categories, ASI01 to ASI10, does the product address, and how?
- If we already run a registry, what does your product add that duplicates nothing we own?
Where Difinity.ai sits
Difinity is a runtime enforcement platform, not a fourth registry, and it is built around a different unit of work: the governed run. An organisation configures its use cases in Hub, along with its agents and the authority each version carries. Chat replies and tool calls run through the same enforcement pipeline. Anything that changes something elsewhere is read by a judge before it runs, against the per-tool policy the agent's author wrote in their own words: a first model tier on AWS Bedrock, a second tier for the calls the first will not commit on, and a person when neither tier can settle it.
What that changes in practice
The action itself leaves through a tool gateway that holds the credential and decides, and an agent cannot hold a credential or reach a system directly. What happened is written to an append-only run trail as it happens, rather than reconstructed from logs afterwards. Only the person the agent is acting for may approve one of its actions, and a run nobody answers expires. Nothing is reviewed on a cycle, and nothing runs before a control that can refuse it has seen it. Governed run records can contribute operational evidence to wider EU AI Act, ISO/IEC 42001, risk and audit processes. Difinity does not determine that an organisation or AI system is compliant, and it does not provide ISO/IEC 42001 certification.
Where this map is soft
Category maps age badly, and this one has two known weak spots. Credo AI's planned enforcement integrations would blur the line between the first group and the third. IBM's agent monitoring capability is reported through search results rather than confirmed on IBM's own site, because the page would not load for us. Every capability statement here comes from vendor marketing rather than a console we logged into, so use the five-minute question set on each vendor rather than trusting anyone's category diagram, including this one.
Frequently asked questions
Is there a direct replacement for Credo AI?
For the registry job, the closest substitutes are other AI inventory and registry tools, and IBM watsonx.governance if you want AI folded into a wider GRC suite. There is no like-for-like replacement that also decides whether a running agent may act, because that is a different product category.
Do we need both a registry and a runtime enforcement platform?
Often, yes. A registry answers which AI systems exist, who owns each one and how it was assessed. A runtime enforcement platform decides whether a specific action executes. Buying two products from the same group is the waste worth avoiding.
How do we compare vendors that all claim runtime governance?
Ask who holds the credential during a tool call and ask to see a refusal. Trace ingestion, continuous evaluation and monitoring all describe reading what happened. Only a product in the path of the action can refuse it.
Where do identity vendors fit?
They cover agent identity and access, which is one requirement inside agent governance rather than the whole of it. Treat them as a component alongside a runtime enforcement platform, not as an alternative to a governance platform.
