Buyer’s guide

How to evaluate an accountable AI platform.

Buyers asking for “accountable AI” or “AI governance” platforms are usually comparing two different kinds of software: platforms that govern an organisation’s AI estate, and platforms that build accountability into specific operational workflows. This page sets out neutral criteria, describes nine established vendors from their own official pages, and shows where CloudSeals fits — including the criteria where it does not.

Method

Each vendor was assessed against the same eighteen criteria using only its own product pages, documentation, pricing pages and trust pages as they stood on the access date. Marketing adjectives were not counted as capabilities. “Not confirmed” means the vendor’s public pages did not state the capability on that date — it is not a claim the vendor lacks it. Where a vendor’s pages could not be loaded (ServiceNow’s product and trust pages returned HTTP 403; several trust centres returned no content), the row is marked accordingly and should be re-checked in a browser. CloudSeals is assessed against exactly the same criteria from its own published pages, and is not ranked. Corrections from any vendor are welcome at trustops@cloudseals.com.

Two kinds of platform

Governance of the AI estate

Inventory every model and agent, classify risk, map to frameworks such as the EU AI Act, NIST AI RMF or ISO/IEC 42001, run assessments and approvals, monitor production behaviour, and govern third-party AI. IBM, Credo AI, ServiceNow, Microsoft Purview, OneTrust, Holistic AI and ModelOp sit mainly here; Fiddler and Arthur add deep runtime observability and agent security.

Accountability inside the workflow

Run a specific operational process — a reconciliation, a safety alert, a carbon figure — so that a policy boundary, a human approval and retained evidence are part of every decision. CloudSeals sits here. It is narrower, and it does the work rather than governing software that does the work.

Many regulated organisations need both: an estate-level view for the governance function, and workflow-level accountability where decisions are actually made. The criteria below apply to either; the pattern of answers tells you which kind you are looking at.

Values: Yes = stated on the vendor’s official page; Partial = stated in a limited or indirect form; Not confirmed = not stated on the pages fetched on the access date. Microsoft is assessed across Purview, Foundry Control Plane and the Azure Machine Learning Responsible AI dashboard because no single Microsoft product covers all criteria.

The vendors, in their own framing

IBM watsonx.governance

IBM frames watsonx.governance as governance that transforms AI investments into measurable business value, governing AI use cases, models, prompts and agents across the lifecycle.

Where it is clearly stronger than CloudSeals: Depth of model-level evaluation (fairness, drift, explainability, gen-AI quality) and FedRAMP/on-prem deployment for regulated buyers.

Official sources (accessed 7 September 2026): www.ibm.com · www.ibm.com · www.ibm.com · www.ibm.com

Credo AI

Credo AI calls itself the trusted leader in AI governance, enabling enterprises to discover AI, enforce policy, manage risk and achieve Measurable Trust across every agent, application, model and AI vendor.

Where it is clearly stronger than CloudSeals: Breadth of pre-built regulatory policy packs and a long list of named integrations across cloud, MLOps and GRC tools.

Official sources (accessed 7 September 2026): www.credo.ai · www.credo.ai · www.credo.ai

ServiceNow AI Control Tower

ServiceNow documentation describes AI Control Tower as combining AI assets and controls in a central hub for governance and management on the Now Platform.

Where it is clearly stronger than CloudSeals: Native to a platform that already runs enterprise workflow, GRC and CMDB, so AI governance and operational case handling sit in one system.

Update, 5 May 2026 release (read 5 October 2026): ServiceNow’s newsroom describes AI Control Tower as discovering AI assets across systems, with continuous monitoring, risk assessment aligned to NIST and EU AI Act frameworks, identity access governance for hyperscaler AI environments, and integrations with providers including Anthropic, OpenAI, AWS, Microsoft and NVIDIA. The ratings table above was scored on 7 September 2026 and has not been re-scored from this release.

Official sources (accessed 7 September 2026): www.servicenow.com · www.servicenow.com · www.servicenow.com · www.servicenow.com · newsroom release (accessed 5 October 2026)

Microsoft Purview (Foundry Control Plane, Azure ML Responsible AI dashboard)

Microsoft positions Purview to mitigate and manage the risks associated with AI usage and implement protection and governance controls for Copilots, agents and other generative AI apps.

Where it is clearly stronger than CloudSeals: Data-security enforcement (DLP, labels, audit retention, eDiscovery) across the Microsoft 365 estate and unmatched certification breadth.

Official sources (accessed 7 September 2026): azure.microsoft.com · learn.microsoft.com · learn.microsoft.com · learn.microsoft.com

OneTrust AI Governance

OneTrust frames AI Governance as shipping AI faster with risk control where AI runs, covering homegrown and third-party AI with shadow-AI detection.

Update, 29 September 2026: OneTrust announced CORIE, a shared intelligence layer in its platform for governing AI agents. Its announcement says CORIE “enforces those rules at the tool call—allowing an action, stopping it, or flagging it for human review” and “creates a record as the work happens, capturing the agent, request, purpose, outcome, and governing policy.” This shows estate-level governance platforms moving into runtime policy enforcement and evidence.

Where it is clearly stronger than CloudSeals: Enterprise GRC/privacy/vendor-risk suite integration and a broad certification portfolio.

Official sources (accessed 7 September 2026): www.onetrust.com · www.onetrust.com · CORIE announcement (accessed 5 October 2026)

Holistic AI

Holistic AI describes itself as the end-to-end AI governance platform trusted by global enterprises running AI at scale.

Where it is clearly stronger than CloudSeals: Automated technical testing (bias, robustness, adversarial, red-teaming) built into the governance workflow.

Official sources (accessed 7 September 2026): www.holisticai.com · www.holisticai.com

ModelOp Enterprise AI Command Center

ModelOp frames its platform as industrialized AI delivery for enterprise leaders, a system of record for ML, GenAI, agentic and vendor AI with governance enforced at delivery time.

Where it is clearly stronger than CloudSeals: Fully self-hosted, no-data-movement deployment aligned to model-risk-management practices in banks and pharma.

Official sources (accessed 7 September 2026): www.modelop.com · www.modelop.com · www.modelop.com · www.modelop.com

Fiddler AI

Fiddler calls itself the AI Control Plane for the Enterprise Agent Workforce, unifying monitoring, evals, enforcement and governance across the lifecycle.

Where it is clearly stronger than CloudSeals: Runtime observability, low-latency guardrails, and mature ML explainability/fairness metrics.

Official sources (accessed 7 September 2026): www.fiddler.ai · www.fiddler.ai · www.fiddler.ai · www.fiddler.ai

Arthur

Arthur positions itself as enterprise-grade agent security & governance that finds every agent running across environments and enforces policies.

Where it is clearly stronger than CloudSeals: Agent discovery and security telemetry with SIEM/EDR integrations (CrowdStrike, Splunk, Elastic, Datadog).

Official sources (accessed 7 September 2026): www.arthur.ai · www.arthur.ai · www.arthur.ai · www.arthur.ai

Adjacent: runtime agent control and security

Two recent announcements sit next to, rather than inside, the platforms compared above. They are not scored against the eighteen criteria because they address a different layer: controlling and securing agents as they run.

NVIDIA Open Agent Safety Platform

Announced 28 September 2026 as “an open software platform and reference system design to strengthen AI security from agent testing to deployment.” NVIDIA describes OpenShell as a secure runtime boundary for controlling how agents execute tasks, and Sentry as an out-of-band watchdog that verifies agent identity, enforces zero-trust access policies and can quarantine an agent. It is infrastructure-level agent safety, not a business-workflow approval and evidence layer.

Official source (accessed 5 October 2026): investor.nvidia.com

Reco

Reco describes itself as securing “agents and their operating environments where applications, identities, permissions and workflows converge.” On 29 September 2026 it announced $55 million in additional funding led by AT&T Ventures, bringing reported total funding to $140 million. It addresses agent, SaaS and identity security, which is complementary to workflow-level approval and evidence.

Official source (accessed 5 October 2026): GlobeNewswire press release

Where CloudSeals stands, criterion by criterion

Assessed from cloudseals.com pages only, with the same rules.

Genuine differentiation: CloudSeals executes the operational workflow itself with the policy boundary, human approval and evidence record built into each decision, and it applies that in three named domains — finance operations, industrial site safety and carbon MRV. Genuine gaps: no AI inventory, no model testing or monitoring, no third-party AI governance, no published deployment options, integrations, pricing, certifications or customer references. Buyers who need estate-level governance should shortlist the vendors above; buyers who need accountable decisions inside those three workflows should talk to CloudSeals and ask for a security review.

Questions to put to any vendor

Where is the approval?

Show the screen where a person approves, and the record that proves they did. Ask what happens if nobody approves.

What does the evidence record contain?

Ask for the field list and an export. If it cannot be shown, it is not evidence yet.

What is enforced, and where?

Policy in a document is not the same as policy applied before an action. Ask which one you are buying.

What is not confirmed?

Deployment model, integrations, certifications, pricing and references. If a page does not say, ask in writing.
