VAPT & Penetration Testing in the United Kingdom

VAPT (Vulnerability Assessment and Penetration Testing) for UK organisations identifies and safely exploits weaknesses across web and mobile applications, APIs, networks and cloud. CyberSigma delivers manual-led testing with audit-ready reports aligned to OWASP, NCSC guidance and ISO 27001 — suitable for Cyber Essentials, PCI DSS, NIS and customer-assurance requirements. We are CERT-In empanelled and PCI QSA (CEMEA) authorised.

Manual-Led Penetration Testing for UK Organisations

Scanners find the obvious; real attackers chain together the subtle. CyberSigma's VAPT combines automated coverage with deep manual testing to surface the exploitable weaknesses that matter — the ones that lead to data breaches, payment compromise and regulatory exposure.

Our testing aligns to OWASP (Top 10, ASVS, MASVS), NCSC guidance and ISO 27001, with reporting that supports Cyber Essentials Plus, PCI DSS v4.0.1, NIS Regulations and enterprise customer due diligence across the UK.

• Web application penetration testing (OWASP Top 10, ASVS).
• Mobile application testing (iOS/Android, OWASP MASVS).
• API and web-services testing (REST, GraphQL, auth flows).
• Internal and external network penetration testing.
• Cloud configuration and security review (AWS, Azure, GCP).
• Retesting to confirm remediation and produce clean evidence.

Why UK Teams Choose CyberSigma for VAPT

Our testers work to recognised methodologies and report findings with clear, reproducible proof-of-concept and prioritised, practical remediation — not scanner noise. Reports are written to satisfy both your engineers and your auditors.

Web and mobile application testing, API testing, internal and external network testing, and cloud security reviews — all manual-led and aligned to OWASP, NCSC and ISO 27001.

Is your VAPT suitable for Cyber Essentials Plus and PCI DSS?

Yes. Our reports are written to support Cyber Essentials Plus, PCI DSS v4.0.1 requirement 11 testing, NIS Regulations and ISO 27001 evidence needs.

How long does a penetration test take?

Typical application or network tests run from a few days to a couple of weeks depending on scope and complexity. We confirm timelines after scoping.

Do you provide a retest after we fix the issues?

Yes. We retest remediated findings and issue a clean attestation suitable for auditors, certification bodies and customers.
