Bank-Grade AI, Built to Hold: The e7n SURE Framework for AI-Native Engineering Risk
How e7n delivers AI-native systems that can be trusted in production, audited without drama, and evolved without fear through the SURE framework.
Financial platforms fail in the details. Not just in lines of code, but in the governance, evidence, and operating discipline that make a system safe to trust. e7n exists to bridge that gap between vision and institutional execution.
We ship AI-driven capabilities fast, without breaking the controls that banks, allocators, and regulators rely on. Our way of working combines Tier-1 engineering standards with startup velocity: prototype quickly, architect for scale, and keep compliance in the loop from day one.
The SURE Framework: Systemic, Unified Risk Engineering
SURE is not a bolt-on checklist. It is a product-engineering operating system that aligns governance, architecture, evaluation, and run-time operations into one evidence-bearing process designed for bank scrutiny and institutional reliability.
It slots cleanly into our blueprint-to-build model, then continues through ongoing operation or hand-off.
What SURE Solves
Fragmented Risk Ownership
Data science, platform, and risk functions often run separate playbooks. SURE replaces ad-hoc control mapping with a single end-to-end assurance thread tied to system architecture and delivery milestones.
Static, Document-Heavy Assurance
Traditional model docs lag reality. SURE turns assurance into a living artifact, automatically collected evidence, traceability, and real-time controls, so your risk posture updates as the system changes.
ML and LLM Ambiguity
GenAI introduces prompt-level failure modes, privacy leakage risks, and evaluation gaps. SURE adds model-agnostic controls that cover classic ML and modern LLM applications under one governable lifecycle.
The SURE Framework: Eight Pillars
1) Governance Baseline, Aligned to External Standards
We anchor every build to a common control language and timeline:
- NIST AI RMF 1.0 for Govern-Map-Measure-Manage across the AI lifecycle, with the Generative AI Profile for GenAI-specific risks and controls
- ISO/IEC 42001 for organizational AI management systems and supplier oversight
- Regulatory overlays including PRA SS1/23 (UK) model risk principles and EU AI Act staged applicability for GPAI and high-risk systems
2) The Assurance-Case Backbone
SURE expresses safety, reliability, and compliance claims as an assurance case (Goal Structuring Notation). Each claim is backed by structured evidence pulled from design reviews, tests, monitors, and audits. This modernizes safety-case practice for AI/ML, where the literature recommends turning assurance into a model-centric, continuously updated artifact rather than a static document.
3) One Supply Chain: DevOps × MLOps × AIOps
We unify software, data, and model assets in a single supply chain:
- SBOM/MBOM/PBOM. Software bill of materials, model bill of materials, and prompt/policy bill of materials tracked in the registry with versioned lineage
- Provenance and policy gates in CI/CD for code, data, features, and models; security scans and bias tests run as first-class checks
- Evidence streams write directly into the assurance case. Industry data shows that treating ML as standard artifacts within the software supply chain improves reliability, governance, and deployment success
4) Model Risk Discipline for Classic ML and GenAI
SURE embeds the banking triad: conceptual soundness, outcome analysis, ongoing monitoring, and extends it for LLM-specific hazards (prompt injection, jailbreaks, tool misuse, data leakage). Guidance for GenAI in finance emphasizes additional testing and controls at validation, plus continuous surveillance in production.
5) Evaluation That Resembles Reality
We run task-level, system-level, and scenario-level evaluations:
- Static evals: unit tests, golden sets, fairness & robustness suites
- Dynamic evals: adversarial prompts, red-team scenarios, counterfactual data, and safety/abuse tests tailored to your domain
- Application-level safety: customized risk taxonomy and evaluation practices validated in production-grade deployments
6) Telemetry, Drift, and Real-Time Risk API
SURE instruments models and LLM apps with run-time risk telemetry: input/output fingerprints, distribution drift, guardrail events, policy violations, and quality signals. Metrics are exported through a Prometheus-style risk API to unify alerting and evidence capture across teams. Research demonstrates practical patterns for real-time model risk aggregation with Prometheus exporters for LLM services.
7) Security-by-Design for AI
Threat modeling extends to model artifacts and inference pathways. We integrate adversarial hardening, anomaly detection, and standard security controls throughout the lifecycle, consistent with enterprise frameworks for autonomous AI systems.
8) Privacy and Memorization Controls
We mitigate training-data leakage and memorization via data governance, differential privacy where appropriate, output filtering, and red-team evals. Recent studies highlight multi-layer defenses during fine-tuning and inference to reduce privacy risk in LLMs.
The SURE Process: From Blueprint to Bank-Ready
SURE is integrated into e7n's delivery model: discovery, blueprint sprint, build & iterate, operate or hand-off. Control is built in, not stapled on.
Stage 0 — Feasibility & Impact
Map use-case to criticality tiers, stakeholders, and regulatory exposure. If LLMs are not necessary, do not use them; when they are, decide open vs. proprietary vs. vendor with ROI and compliance in view. Output: decision memo with control implications.
Stage 1 — Blueprint Sprint (≈2 weeks)
Define the target architecture, data contracts, and control plan. Build the first assurance case skeleton and evaluation plan. Create SBOM/MBOM/PBOM and the initial evidence registry. Output: blueprint, pilot backlog, and acceptance criteria tied to risk objectives.
Stage 2 — Control-Informed Build
Implement features and controls together: model registry, policy gates, eval harnesses, secrets/hardening, run-time telemetry. Automated tests feed the assurance case.
Stage 3 — System Proving
Execute adversarial testing, failover drills, operational runbooks, and human-in-the-loop reviews. Validate conceptual soundness and outcome analysis; finalize monitoring for go-live. Output: go/no-go packet with assurance evidence aligned to PRA/NIST/ISO anchors.
Stage 4 — Operate
Risk metrics flow into dashboards and alerts. Deviations trigger pre-agreed responses: fallback models, circuit breakers, or human takeover, with incident post-mortems writing back into the assurance case.
Stage 5 — Audit & Renewal
Periodic reviews update the case, re-baseline evals, and refresh the risk taxonomy as regulations phase in, including the EU AI Act obligations for GPAI and high-risk systems.
How SURE Looks in Practice
Example A — Trade Surveillance Triage with LLM Assist
Goal: reduce analyst triage time while preserving evidentiary integrity.
Controls:
- Retrieval-grounded generation with immutable citations; prompt policies as code with PBOM
- Red-team prompts for manipulation; hallucination budget with auto-fallback to deterministic rules
- Run-time logging of inputs/outputs, confidence, and overrides; drift alerts if case types change
Assurance:
- Claims: "Summaries are faithful to source," "No PII leakage," "Analyst remains final authority"
- Evidence: RAG faithfulness scores, PII filters, override statistics, audit sampling with inter-rater agreement
- Regulatory mapping: model risk policy under SS1/23; operational safeguards aligned with NIST RMF; EU AI Act transparency where applicable
Example B — Client Reporting Q&A for Private Banking
Goal: natural-language answers grounded in approved facts.
Controls:
- Content provenance pinned to document hashes; financial-term evals and abuse filters; user-scope RBAC enforcement at retrieval
Assurance:
- Leakage tests and value-at-risk of misinformation via scenario evals; weekly recalibration gates

KPIs That Matter
Why This Works
Standards-first, Product-native
SURE fuses NIST/ISO/PRA guidance with actual software and data delivery. You get bank-grade controls that keep pace with shipping.
Assurance as Code
Evidence is automatic, repeatable, and stays in lock-step with the system. Literature on AI assurance argues for exactly this shift.
Unified Supply Chain
One pipeline for code, data, and models reduces failure modes and improves traceability and compliance.
GenAI-specific Rigor
Banking research and practice now call for expanded model validation and monitoring tailored to LLMs; SURE bakes it in.
Conclusion
Regulators will keep raising the floor, and markets will keep raising the bar. You need both speed and assurance.
SURE is how e7n delivers AI-native systems that can be trusted in production, audited without drama, and evolved without fear across wealth, brokerage, execution, crypto infrastructure, and deep-tech SaaS.
It is how we turn ambitious ideas into resilient platforms that stand up to real-world demands.
