Large UK banking group with multi-brand presence
Modernising customer and payment screening for agility and oversight
From vendor-driven black boxes to a configurable, API-first screening platform.
Re-architected screening as a first-class API platform rather than a point solution
Delivered modern observability and non-repudiation audit trails
Enabled efficient onboarding of new screening providers and policies
Supported high-availability requirements under significant transaction volumes
Context
The bank relied on an ageing screening technology stack that limited change velocity. Each rule or provider change triggered time-consuming deployments and regression cycles. Monitoring and auditing were fragmented, making regulatory conversations harder than they needed to be. The bank wanted to retain its choice of vendors, but regain control over how screening was orchestrated, monitored and audited.
The Challenge
- →
Decouple orchestration from vendor products
- →
Retain existing providers while enabling measured migration and dual-running
- →
Provide operational transparency across brands, lines of business and jurisdictions
- →
Reduce time-to-change for policy and workflow updates from months to weeks
Our Approach
API-first platform design
Screening exposed as versioned APIs with explicit SLAs and behaviour. Downstream systems could integrate via stable contracts while the platform evolved underneath.
Modern architecture and progressive engineering practices
Microservices with idempotent APIs and failure-aware design. Containerised workloads deployed on bank-approved cloud platforms. Shift-left testing, including contract testing and automated regression suites.
Business metrics & operational monitoring baked in
Metrics for hit rates, timing, error patterns and manual review loops. Built-in dashboards for risk, operations and technology.
Transition architecture
Side-by-side integration to de-risk migration from legacy screening engines. Pluggable adaption layer for current and future providers.
Outcomes
- →
A governed screening platform capable of supporting multiple vendor engines without locking into any one provider.
- →
Improved clarity for regulators and internal governance functions.
- →
Reduced operational friction and clearer ownership of performance, coverage and exceptions.
- →
A foundation on which AI-driven triage and prioritisation can be safely added.
