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, capturing every language model call, tool invocation and reasoning step in production with tamper proof immutable traces, exporting regulator facing evidence packs in under a minute, and carrying the most complete regulatory mapping in this index, 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. Both document seven of the nine regulatory axes, and both grade C on liability and recourse, which for two companies selling accountability infrastructure is the thing to put in writing before signing either.
- Your obligations span more than model risk. Block Convey maps them individually rather than as a list of logos, covering United States banking model risk guidance, state cybersecurity rules applied to AI use by covered entities, fair lending including the confirmation that equal credit opportunity requirements reach AI driven decisions and that adverse action notices need specific reasons, insurance model bulletins, and European AI, operational resilience and data protection regimes. It holds A on regulatory status and licensure, the most complete regulatory mapping in this index.
- 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, regulator facing evidence packs export in under sixty seconds, agent trajectories and model audits reconstruct how a decision was reached, and prompts are versioned through a library, treating them as controlled model artefacts 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 the security critical path entirely, and a trust centre is published. Block Convey grades C on security certifications with no attestation, certification or trust centre located.

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. The AI FinTech Index grades it A on AI centrality, regulatory status and licensure, model risk management and transparency and model supply chain disclosure, with B on institution coverage, GLBA posture, autonomy and oversight, AI governance and bias disclosure, deployment residency and integration depth, documenting seven of the nine regulatory axes the index tracks against an index average of 2.93 across 489 vendors. Its regulatory mapping is the most complete in the index, running obligation by obligation across United States banking model risk guidance, state cybersecurity rules, fair lending, insurance model bulletins and European AI and operational resilience regimes. Operational evidence, commercial transparency, AI safety, security certifications and liability and recourse are graded C.

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. The AI FinTech Index grades it A on AI centrality, autonomy and oversight and model risk management and transparency, with B on institution coverage, regulatory status, AI governance and bias disclosure, integration depth, deployment residency, security certifications and model supply chain disclosure, documenting seven of the nine regulatory axes the index tracks against an index average of 2.93 across 489 vendors. Its veto engine imports only standard library modules with no third party packages, removing external dependency risk from the security critical path. Operational evidence, commercial transparency, GLBA posture, AI safety and liability and recourse are graded C.

Common questions
Is Block Convey better than EVE AI Core?
They document the same amount, seven of the nine regulatory axes each, and they 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, holding the most complete regulatory mapping in this index, 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.

Is recording everything enough, or do I need something that blocks?
This is the live disagreement between them and it is worth putting to both. 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. The honest framing is that a complete record makes a failure findable and a gate makes it impossible, and those are different guarantees at different costs. Ask Block Convey 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. Both grade C on liability and recourse. 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 and genuinely, 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 the record. Both also grade C on operational evidence and commercial transparency, so neither publishes an outcome or a price.

How does the AI FinTech Index grade Block Convey and EVE AI Core?
Both are graded on the same fifteen capability axes, with every grade traceable to the public artifact it was read from and the date it was verified, and the index publishes no composite score. Each documents seven of the nine regulatory axes at A or B, against an index average of 2.93 across 489 vendors. Block Convey holds A on AI centrality, regulatory status, model risk management and model supply chain disclosure, with B on institution coverage, GLBA posture, autonomy, governance and bias, deployment residency and integration depth, and C on operational evidence, commercial transparency, AI safety, security certifications and liability. EVE AI Core holds A on AI centrality, autonomy and oversight and model risk management, with B on institution coverage, regulatory status, governance and bias, integration depth, deployment residency, security certifications and supply chain, and C on operational evidence, commercial transparency, GLBA posture, AI safety and liability.

Both document seven of the nine regulatory axes and the tie conceals a real argument between them that a buyer should hear rather than average out. 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. Both should be asked it. The shared silence is sharper than either vendor's individual gaps.
Both grade C on operational and outcome evidence, so neither publishes a customer outcome, and both grade C on commercial transparency, so neither publishes a price. Both grade C on liability and recourse, and that is conspicuous for two companies whose entire product is accountability infrastructure: Block Convey states nothing about what it stands behind if an evidence pack proves incomplete under examination or a guardrail fails to strip regulated data before it reaches an external model, and 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, grading C with no attestation or trust centre located, for a company that maps its own releases against payment card and operational resilience standards on its customers' behalf.
