Service
IT Audit
Technical due diligence and audit work for regulated financial institutions — architecture review, database health, cloud readiness, application and integration audits, and pre-procurement vendor due diligence. Led by senior banking specialists with deep platform certifications, including an Oracle Certified Master and an AWS-certified Solution Architect.
"IT audit" means different things in different contexts. The most common search intent is for the regulator-independence variety — FCA Section 166 reviews, PCI DSS QSA assessments, formal internal audit. That is not what we do. We deliver the technical layer underneath: due diligence and audit work by senior banking specialists who have built similar platforms. Architecture reviews using Enterprise Architecture frameworks. Cloud audits across the major hyperscalers, led by an AWS-certified Solution Architect with hands-on experience of multi-cloud and sovereign-cloud architectures. Database health audits led by an Oracle Certified Master.
What You Get
Technical architecture review
End-to-end review of the technology stack underlying a platform, business line, or programme — service boundaries, integration patterns, scalability headroom, and the operational dependencies that determine whether the system survives growth. Where scope justifies it, we model current and target state using TOGAF or ArchiMate so findings sit inside a structured view of the estate.
Database performance, security, and health audit
OCM-led review of Oracle, SQL Server, PostgreSQL, or MySQL estates — execution plans, indexing, statistics, HA and replication configuration, backup and DR posture, and access controls. Includes a prioritised remediation roadmap. Particularly valuable before high-volume periods, after a major incident, or as preparation for a cost rationalisation programme.
Cloud architecture and migration readiness audit
Review of existing or planned cloud architecture — workload placement, service selection, network and security design, identity and access patterns, and integration with on-premise estates. Equally applicable to AWS, Azure, Google Cloud, and sovereign-cloud deployments.
Application and integration architecture audit
Review of the application portfolio and integration fabric — service contracts, event flows, idempotency and retry patterns, settlement reconciliation, latency-budgeted critical paths, and the integration debt that builds up across multi-year programmes. Suitable for institutions whose integration layer has grown organically and now limits change velocity, or for buyers scoping a major migration.
Cost optimisation and licensing audit
Targeted review of high-cost technology line items — Oracle licensing, cloud spend, vendor contracts — to find where capacity, licence terms, or cloud architecture have drifted from optimal cost. OCM-led Oracle right-sizing; cloud workload, instance, and commitment review across the major hyperscalers. Deliverable includes quantified saving estimates, not just findings.
Pre-procurement vendor and technology due diligence
Independent technical evaluation of vendor platforms during selection — core banking, card processing, CRM, BI, or data platform RFPs. We assess each vendor's technical fit against your workload, integration estate, and regulatory geography, drawing on production experience with the platforms rather than analyst-report summaries.
Our Approach
Discovery & Scoping
We define the scope of the audit, gather documentation, and align on objectives with your team.
Assessment
Hands-on review of the target system — architecture, database, cloud, integration, configuration, and operational telemetry. Findings cite specific files, queries, configurations, or behaviours that support them.
Findings Report
Categorised findings with severity ratings and evidence references. Each finding includes root cause where identifiable, so remediation addresses the cause rather than the symptom.
Recommendations
Prioritised, actionable recommendations with clear implementation guidance.
Follow-up Review
Optional follow-up engagement to verify that critical issues have been resolved.
