Cybersecurity service
Application & API Security
Assurance for the layer where most citizen and enterprise data is actually processed — application logic, authentication, authorisation and the APIs that connect departments, platforms and partners.
The problem
Why organisations engage this service
- Digital services expose more API surface than user interface, and API defects are frequently missed by interface-only testing.
- Authorisation logic errors allow access to records belonging to other citizens, entities or departments.
- Security is often assessed after build, when design-level defects are expensive to correct.
Scope
What is covered
- Secure code review (manual and tool-assisted)
- API inventory, contract and authorisation review
- Authentication, session and token security review
- Role and entitlement model review
- Input validation, output encoding and injection defences
- Secrets handling and configuration security
- Secure SDLC and pipeline security advisory
- Third-party and dependency risk review
Methodology
How the work is performed
- 01
Design and threat review
Data flows, trust boundaries and abuse cases for the application and its APIs.
- 02
Code and configuration review
Targeted manual review of security-relevant modules supported by tooling.
- 03
Dynamic verification
Authenticated testing of business logic, authorisation and API behaviour.
- 04
Developer walkthrough
Findings explained to the build team with concrete remediation patterns.
- 05
Validation
Re-review of corrected code paths and closure reporting.
Deliverables
What you receive
- Threat model and trust-boundary documentation
- Prioritised code and API findings with remediation patterns
- Authorisation matrix observations
- Secure SDLC recommendations for the programme
- Validation and closure report
