Systems that pass functional testing still fail in production. We stress-test, load-test, and validate every non-functional dimension — before your customers discover the problem.
Start a Performance Assessment →The most costly production incidents are not functional defects — they are performance collapses, security breaches, and accessibility failures that no unit test catches. These are the risks that non-functional testing is designed to surface before they reach customers.
Systems perform perfectly in UAT and collapse on launch day or during a campaign spike. Load testing reveals this — before it becomes front-page news.
A 1-second delay in page response reduces conversions by up to 7%. For financial services, insurance, and healthcare, performance is a commercial metric, not a technical one.
WCAG 2.2 compliance is required by UK public sector and increasingly by regulated industries. Failure creates legal exposure and excludes 1 in 5 users.
DDoS resilience, session management under load, and API rate limiting are security concerns that only manifest under performance test conditions.
We cover the full non-functional testing spectrum — each test type engineered to expose a specific category of production risk.
Simulating realistic concurrent user volumes to validate response times, throughput, and resource utilisation against defined SLAs.
Pushing beyond design limits to find the breaking point, validate failure modes, and confirm graceful degradation rather than catastrophic collapse.
Critical for insurance quote engines, banking portals, healthcare appointment systems, and retail during campaign launches.
Identifying memory leaks, connection pool exhaustion, and resource degradation that only appear after hours of sustained operation.
Automated and manual WCAG 2.2 AA/AAA assessment — screen reader compatibility, keyboard navigation, colour contrast, and assistive technology compliance.
Session management under load, API abuse pattern detection, rate limiting validation, and DDoS resilience assessment.
Defining the test scope, load model, SLAs, and success criteria — aligned to your architecture and business risk profile before a single script is run.
Establishing a current performance baseline against which all future releases are measured — making performance regression visible and actionable.
Full load, stress, and spike testing before major releases, infrastructure migrations, or high-traffic campaigns. Clear go/no-go reporting for release decisions.
Automated and manual accessibility assessment with a prioritised remediation roadmap. Delivered as a formal report suitable for legal and regulatory submission.
Designing the observability stack — APM, alerting thresholds, and dashboards — so performance issues are detected in production before users report them.
Advisory engagement for architecture and development teams — building performance into the design, not bolting it on at the end of the delivery cycle.
Every system has a breaking point. The only question is whether you find it in a controlled test environment or during a live incident.
