The AI Decision Control Plane for regulated lending

Stop AI agents before they make the wrong call.

Sentinel is a decision gate that sits between your AI agents and real financial workflows. It evaluates every proposed action against policy, security, fair lending, explainability, and audit controls, then returns APPROVE, BLOCK, FLAG, or ESCALATE before execution.

Not observability. Not a registry. Enforcement — before execution.

Why Sentinel

The AI Decision Control Plane for regulated lending

A decision gate in the path of execution — built so every AI decision is examiner-defensible.

Enforcement in the path of execution

Inline decision gate, <1ms verdict, BLOCK before execute, deterministic verdict precedence.

Built for examination

Proof-of-Agent (SHA-256), examiner-readable reasons, Know Your Agent dossiers; mapped to NIST AI RMF, EU AI Act, SR 11-7, ECOA/FCRA/TILA, CFPB/OCC/Fed/FDIC.

Fair lending by construction

Disparate-impact and prohibited-factor detection, ECOA reason codes, QM 43% DTI checks, drift monitoring.

Your data stays yours

Self-hosted, zero data egress by default; SOC 2 / ISO 27001 in progress; SSO/SAML/OIDC, RBAC.

Decision Pipeline

Every agent action is treated as evidence.

Eleven stages of control, in the path of every lending decision — not a dashboard you read after the loss.

It is an inline decision gate with a complete, examiner-readable trace for every stage of control.

Select any stage to see what it does and where it lives in the docs.

Control Surfaces

Governance that runs in the path of execution.

Behavioral rules

Threshold, range, expression, list, regex, required-field, prohibited-field, conditional, and composite rules are evaluated before the agent can act.

Know Your Agent

A standing identity file for every AI agent — so you always know what each agent is allowed to do, on what data, under which rules.

Each agent gets an operational dossier: intended use, inferred data categories, template lineage, active rules, compliance tags, and explainability narrative.

Proof of Agent

A tamper-evident receipt on every decision — cryptographic proof of exactly which agent, rules, and config produced the verdict.

Each verdict carries SHA-256 bindings that tie the decision to registry state, rule state, and replayable audit strings.

Human escalation

High-risk decisions can move to an approval queue instead of being forced into a false binary approve/block flow.

Security

Prompt injection defense

Seven attack families, including role manipulation, delimiter injection, data exfiltration, social engineering, homoglyph obfuscation, and multi-turn attacks.

Privacy

PII and PHI redaction

24 sensitive data types, including SSN, card numbers, IBAN, Aadhaar, PAN, passport, medical record numbers, API keys, and contact data.

Fair Lending

Bias and adverse action

Disparate impact checks, prohibited factor detection, ECOA reason codes, and drift monitoring for production credit workflows.

Observability

Agent traces

Sessions, traces, spans, token cost, p50/p95/p99 latency, throughput, error rates, and anomaly scores across the decision lifecycle.

Explainability

Examiner-readable reasons

Plain-English summaries, per-rule explanations, counterfactual suggestions, feature contributions, and complete decision paths.

Deployment

Self-hosted by default

FastAPI, SDK, LangChain integration, Docker, Helm, PostgreSQL persistence, API key auth, RBAC, and SSO/SAML/OIDC support.

Regulatory Coverage

Built for financial institutions that expect examination.

The product maps AI-agent behavior to the controls banks, lenders, insurers, and credit unions already have to defend.

FrameworkWhat it requiresHow Sentinel addresses itReference

NIST AI RMF

GOVERN, MAP, MEASURE, and MANAGE functions with documented controls and evidence.

All four functions mapped to concrete Sentinel controls — policy versioning and RBAC, agent classification, bias and drift measurement, and enforced guardrails — each producing reportable evidence.

Brief →

EU AI Act

Risk classification, transparency, human oversight, data quality, and logging for high-risk systems.

Four-tier risk classification, plain-English explainability for transparency, the ESCALATE verdict for human oversight, and full data-quality scoring and decision logging on every call.

Brief →

SR 11-7

Model inventory, periodic validation, and auditable model risk governance.

Model inventory with metadata, periodic review tracking that flags overdue validations, and a replayable audit trail tying every decision to the model and rules that produced it.

Brief →

ECOA / FCRA / TILA

Fair lending, specific adverse-action reasons, lawful credit-report use, and QM debt-to-income limits.

Disparate-impact and prohibited-factor detection, ECOA reason codes generated by the explainability module, FCRA-tagged rules, and QM 43% DTI checks enforced before the agent acts.

Brief →

CFPB / OCC / Fed / FDIC

Examiner-ready governance for AI-assisted lending, scoring, pricing, and line management.

Guidance-aware agent templates per use case, with examiner-readable decision traces and exportable compliance evidence aligned to each supervisor’s expectations.

Architecture

A narrow gate between agents and consequences.

Sentinel integrates as an API, SDK, or LangChain guardrail. A proposed action enters on the left and only leaves as a verdict.

The agent proposes a decision with parameters, context, and optional RAG evidence. Guardrails screen it first, the rule engine evaluates compliance-tagged business rules, and monitoring records every signal — then one of four verdicts returns before the agent executes. Decisions can be stored in memory for development or persisted to PostgreSQL for production audit trails.

The control layer he wished existed.

Sentinel is built by Abdul Mallick, founder of Integrity Stack. He has run model governance for consumer credit at Capital One, built bank stress-testing products and served as interim Chief Data Officer for a regulated bank’s wind-down, and currently advises the U.S. SEC on risk analytics. PhD in Engineering. Sentinel is the control layer he wished existed every time AI met an examiner.
