Use Case Recommendations
Best for: Kakunin
Kakunin is compliance infrastructure that applies KYC-style identity to AI agents. Each agent is registered and certified in under three seconds, at which point AWS KMS issues an X.509 certificate binding the agent's identity, its operator and the actions it is permitted to take — the argument being that API keys carry no provenance and no revocation story, while certificates do. From there every agent action, decision and transaction streams to an ingest endpoint rated at 1,000 events per second with p99 latency around 200ms, building an append-only immutable audit log. Behavioural drift detection runs continuously against that stream, and content-risk scoring grades what the agent said rather than only what it did, producing a rolling 30-day trust score with automatic revocation below a 0.85 threshold. Public verification of an agent passport resolves in under 500ms. The output most buyers care about is the last step: one API call generates a regulator-ready compliance report as signed PDF and JSON, mapped to NIST AI RMF, the EU AI Act, MiCA, ISO 27001 or another of the six frameworks it covers. Pricing is per certified agent rather than per seat, with a 30-day free trial and optional bring-your-own-account alert channels for Slack, PagerDuty and Twilio SMS or WhatsApp.
Ideal use cases:
- •Teams or individuals who need x.509 certificate issuance via aws kms
- •Teams or individuals who need immutable append-only audit log at 1,000 events/sec
- •Teams or individuals who need behavioural drift detection and content-risk scoring
- •Teams or individuals who need rolling 30-day trust score with auto-revoke
- •Anyone focused on compliance workflows
- •Anyone focused on agents workflows
Best for: Tenure
Tenure is an AI proxy that sits between your chat clients, IDEs and agents and the model, doing two jobs at once: supplying institutional memory and enforcing policy on what the agent is allowed to do. Its framing is that asking a model to obey a fragile system prompt is a losing battle, so the enforcement should live outside the model — the model does the thinking, Tenure does the policing. Memory is structured rather than a vector blob: conversations, code and docs are distilled into 'beliefs' that get reinforced, deduplicated or superseded over time, and contradictions are flagged for review instead of being silently overwritten. Knowledge sources include Confluence, AGENTS.md files, architecture decision records, ordinary docs, and manually authored beliefs. Memory modes let a team pick its trust level — observe-only, curated, adaptive or document-driven — and scoped tokens limit what each individual client or agent may read, write, extract and inject. Project Resume lets you pick up where you left off in any repository. GroundEval turns observed agent behaviour into reviewable policy, so what an agent actually did becomes what it is permitted to do. It runs in VS Code and VSCodium natively and works with mobile clients, Open WebUI and self-hosted agent gateways. The company markets it for AI governance and EU AI Act traceability, with audit trails and SCIM deprovisioning, and publishes a benchmark paper.
Ideal use cases:
- •Teams or individuals who need belief extraction, merging and explicit contradiction handling
- •Teams or individuals who need scoped tokens limiting read, write, extract and inject per client
- •Teams or individuals who need four memory modes from observe-only to document-driven
- •Teams or individuals who need groundeval turns observed agent behaviour into reviewable policy
- •Anyone focused on memory workflows
- •Anyone focused on governance workflows
