VAPT: can weaknesses be found and exploited?
A vulnerability assessment identifies candidate weaknesses across a defined technical scope. Penetration testing adds human validation and controlled exploitation. The result is a point-in-time view of technical exposure, not a conclusion about the entire security programme.
Security audit: are controls designed and operating?
A security audit evaluates selected governance, process and technical controls against defined criteria. It may review documents, configurations, records, samples and interviews. The conclusion depends on scope, criteria, period and evidence.
Compliance assessment: is there evidence against an obligation?
A compliance assessment compares the organisation's arrangements and evidence with a law, regulation, contract, standard or framework. Compliance does not prove that no vulnerability exists, and a clean penetration test does not prove compliance.
When to use each
- Use VAPT before release, after material change, for periodic technical validation and when exposure needs investigation.
- Use a security audit to evaluate control design and operation across a programme, system or supplier.
- Use a compliance assessment to prepare for or demonstrate alignment with defined obligations.
How they work together
A compliance requirement may call for vulnerability management and testing. The audit can evaluate whether that process is governed and operating. VAPT provides technical findings and remediation evidence within the wider control system. Each strengthens the others without replacing them.
Questions before commissioning work
- What decision will the assessment support?
- What systems, locations, period and entities are in scope?
- Which criteria or test method will be used?
- What evidence and access will be available?
- Who owns remediation and risk acceptance?
- Will corrected findings be retested or otherwise verified?
