Testing services

Independent testing with clear remediation outcomes.

Every engagement is tailored to the application, interfaces, business processes, data sensitivity, users, and regulatory context in scope. You receive agreed rules of engagement, a technical report, an executive summary, a developer debrief, and retesting for agreed remediation items.

Web application testing

Test the applications your customers and staff rely on.

Authenticated and unauthenticated testing of web applications, portals, administrative consoles, customer self-service platforms, and payment journeys.

Authentication, session management, and multi-factor authentication bypass
Authorisation, privilege escalation, and tenant-isolation weaknesses
Injection, deserialisation, file-upload, and server-side request flaws
Business-logic, payment-flow, workflow, and account-abuse scenarios
Client-side, script, and payment-page integrity issues

Scope a web application test

API testing

Secure the interfaces behind digital and payment services.

Testing of REST, GraphQL, SOAP, webhook, partner, open-banking, and digital financial-services APIs, whether consumed by web, mobile, customer, or supplier applications.

Broken object-level and function-level authorisation
Token, key, OAuth, OpenID Connect, and machine-identity handling
Excessive data exposure, mass assignment, and insecure defaults
Rate limiting, abuse, replay, fraud-relevant, and transaction-logic weaknesses
Schema, documentation, versioning, and shadow or undocumented endpoints

Scope an API test

Mobile application testing

Validate mobile apps, wallets, and on-device data.

iOS and Android testing covering the application binary, local storage, transport, authentication, device controls, and the backend services on which the app relies.

Insecure local storage, caching, logging, and credential retention
Transport security, certificate pinning, and interception resistance
Reverse engineering, tampering, root and jailbreak resilience
Device binding, biometric flows, deep links, and session handling
USSD, wallet, payment transaction, and API abuse paths

How testing works

Designed to be thorough, safe, and useful to your teams.

Scope and rules of engagement. Agree systems, accounts, environments, test windows, handling requirements, contacts, and explicit authorisation.
Testing and validation. Assess the attack surface, test controls, validate exploitable weaknesses, and avoid unnecessary disruption.
Reporting and debrief. Provide technical detail, business context, prioritised remediation, and a management-level view of material risk.
Retesting and closure. Verify agreed fixes and provide evidence of remediation status for stakeholders, customers, auditors, and regulators.

What you receive

Evidence that supports remediation and assurance.

Technical findings report

Reproducible detail, affected assets, severity context, evidence, and remediation guidance for technical owners.

Executive summary

A clear explanation of material risk, business impact, priorities, and decisions for leadership and governance stakeholders.

Developer debrief

A practical walkthrough of findings with the people responsible for resolving them.

Retesting evidence

Validation of agreed remediation so you can show progress rather than simply report intentions.
