Understand the difference

Vulnerability assessment vs penetration testing

Vulnerability Assessment

Identify and assess weaknesses in systems, applications and infrastructure.

  • Asset and service discovery
  • Vulnerability scanning
  • Manual validation
  • Risk assessment and prioritisation
  • Remediation recommendations

Penetration Testing

Actively test whether identified weaknesses can be exploited and determine their practical business and security impact.

  • Engagement planning
  • Attack-surface analysis
  • Controlled exploitation
  • Privilege and access testing
  • Impact validation, reporting and remediation guidance
  • Retesting where applicable

Automated scanning supports discovery, but a full penetration test also requires controlled manual analysis, validation and professional judgement.
