Block Convey vs EVE AI Core (2026)
The decision is whether a complete record of what your AI did is a control or only evidence of one, and these two have taken opposite answers seriously enough to build on them. Block Convey observes and evidences. It captures every language model call, tool invocation and reasoning step in production with tamper proof immutable traces, and exports regulator facing evidence packs in under a minute. Its regulatory mapping runs obligation by obligation across banking model risk guidance, state cybersecurity rules, fair lending, insurance model bulletins and the European regimes. EVE AI Core intercepts and prevents, and argues explicitly against the other category: where validation shows a model may produce non compliant output under certain input conditions, the failure is conditional, so reviewing output afterwards will miss it and the control must stop that output reaching a decision maker at all. That argument lands against sampling and only partly against Block Convey, whose record is complete rather than sampled, which narrows the real question to timing rather than coverage. Neither says what it stands behind when it is wrong, a gap that stands out for two companies selling accountability infrastructure.
- Your obligations span more than model risk. Block Convey maps them individually rather than as a list of logos. Its map covers United States banking model risk guidance, state cybersecurity rules applied to AI use by covered entities, and insurance model bulletins. On fair lending it confirms that ECOA requirements reach AI driven decisions and that adverse action notices need specific reasons. In Europe it covers the EU AI Act, DORA and data protection rules.
- The leak you are worried about is staff pasting into consumer assistants. PRISMX is a managed browser extension enforcing data loss prevention at the endpoint, intercepting paste and prompt traffic so personal data, health data and source code never reach an external model. EVE AI Core governs your own agent estate and does not address this.
- You want the evidence pack rather than the gate. Traces are tamper proof and immutable from creation, and regulator facing evidence packs export in under sixty seconds. Agent trajectories and model audits reconstruct how a decision was reached. Prompts are versioned through a library and treated as controlled model artifacts rather than editable configuration.
- A complete record is not the same as a control, and you agree. EVE AI Core makes this argument directly: where validation shows a model may produce non compliant output under certain input conditions, reviewing a log afterwards cannot be an adequate control because the failure is conditional, so the control must be a mechanism preventing that output reaching a decision maker at all. It intercepts every action in under a millisecond, fail closed, with no language model in the decision path.
- You want evidence that does not depend on the vendor. Every verdict emits a signed certificate bound to the exact policy version in force, appended to hash chained trails aggregated into signed tree structures, verifiable offline by a third party with no vendor service in the loop.
- You want the security critical path inspectable. The veto engine imports only standard library modules with no third party packages at all, plus a deliberate load time module freeze guard, which removes external dependency risk from that path entirely. A trust center is published. Block Convey publishes no attestation, certification or trust center.

The short version of each
Block Convey
Block Convey builds two AI governance layers for banks, asset managers, insurers and fintechs. PRISM captures every language model call, tool invocation and reasoning step in production, scores quality, applies guardrails that strip regulated identifiers at ingestion, and exports regulator facing evidence packs in under a minute from tamper proof immutable traces. PRISMX is a managed browser extension enforcing data loss prevention on consumer assistants at the endpoint. According to the AI FinTech Index, it documents in detail how central AI is to the product, the regulations it maps, accuracy and validation, and the models and providers it is built on. Its regulatory mapping runs obligation by obligation across United States banking model risk guidance, state cybersecurity rules, fair lending, insurance model bulletins, the EU AI Act and DORA. It says little about customer results, pricing, AI safety, security certifications or what happens when it is wrong.

EVE AI Core
EVE AI Core is a deterministic control plane that intercepts every AI action before execution rather than reviewing it afterwards, returning an allow, block or modify verdict against versioned policy packs in under a millisecond, fail closed and with no language model anywhere in the decision path. Every verdict emits a cryptographically signed certificate bound to the exact policy version in force, appended to hash chained trails, replayable on demand and verifiable offline by a third party without the vendor in the loop. According to the AI FinTech Index, it documents in detail how central AI is to the product, what it does on its own and who checks it, and accuracy and validation. Its veto engine imports only standard library modules with no third party packages, removing external dependency risk from the security critical path. It says little about customer results, pricing, privacy terms, AI safety or what happens when it is wrong.

Common questions
Is Block Convey better than EVE AI Core?
They document about the same amount and disagree about method. Block Convey observes and evidences: every language model call, tool invocation and reasoning step captured in production, with regulator facing evidence packs exporting in under a minute. EVE AI Core intercepts and prevents: every action allowed, blocked or modified in under a millisecond against versioned policy before it executes. Block Convey also covers far more regimes and adds endpoint data loss prevention on consumer assistants. If the gap is proving compliance across many obligations, Block Convey. If it is stopping a specific non compliant output from ever reaching a decision maker, EVE AI Core. Graded by AI FinTech Index against the same capability axes from each vendor's own published materials, verified August 23, 2026. No vendor pays for placement.
Is recording everything enough, or do I need something that blocks?
This is the live disagreement between them. EVE AI Core argues no: where validation shows a model can produce non compliant output under certain conditions, the failure is conditional, so reviewing output afterwards will miss it and the control has to prevent the output reaching a decision maker. Block Convey's answer is that its record is not a sample, capturing every call, tool invocation and reasoning step with tamper proof immutable traces and versioned prompts, which is a stronger position than the one EVE AI Core's argument targets. A complete record makes a failure findable and a gate makes it impossible, and those are different guarantees at different costs. Block Convey does not say what happens between the non compliant output and the review that finds it.

Which one accepts responsibility if its evidence fails under examination?
Neither, and for two vendors selling accountability that is the finding. Block Convey describes nothing about what it stands behind if an evidence pack proves incomplete under examination, or if a guardrail fails to strip regulated identifiers before data reaches an external model. EVE AI Core describes nothing about what happens if its gate wrongly blocks a legitimate action. Both improve the affected consumer's position indirectly, since specific adverse action reasons generated from recorded reasoning are exactly what a declined applicant is owed, and neither states whether that person can obtain it. Neither publishes an outcome or a price. Graded by AI FinTech Index against the same capability axes from each vendor's own published materials, verified August 23, 2026. No vendor pays for placement.
Where does each publish the most, and the least?
Block Convey publishes most on its AI, the regulations it maps, accuracy and validation, and the models it is built on. It says little about customer results, pricing, AI safety, security certifications or liability. EVE AI Core publishes most on its AI, what it does on its own and who checks it, and accuracy and validation. It says little about customer results, pricing, privacy terms, AI safety or liability.

The two document about the same amount, and that tie conceals a real argument between them. EVE AI Core's regulatory reasoning contains a direct critique of the observe and evidence category Block Convey occupies: it argues that where validation identifies a model may produce non compliant output under certain input conditions, periodic review of a sampled output log is not an adequate control, because the failure is conditional and sampling will miss it.
That argument lands against sampling and only partly against Block Convey, whose traces capture every language model call, tool invocation and reasoning step rather than a sample, which narrows the question to whether a complete record is a control or only evidence of one. The shared silence is sharper than either vendor's individual gaps. Neither publishes a customer outcome or a price.
Neither says what it stands behind, which is conspicuous for two companies whose entire product is accountability infrastructure. Block Convey states nothing about an evidence pack that proves incomplete under examination or a guardrail that fails to strip regulated data before it reaches an external model. EVE AI Core states nothing about what happens if the gate wrongly blocks a legitimate action.
Block Convey's security position is the more conspicuous of the two, with no public attestation or trust center, for a company that maps its own releases against PCI DSS and operational resilience standards on its customers' behalf.
