PENETRATION
TESTING

Conducted by highly experienced UK-based security professionals. Required by PCI DSS, ISO 27001, NHS DSPT, SOC 2, and most enterprise supply chains — we find real vulnerabilities in your networks, applications, and cloud environments before the attackers do.

🌐

INFRASTRUCTURE TESTING

External and internal network penetration testing covering perimeter defences, lateral movement risks, network segmentation validation, and wireless (802.11) security assessments.

🔗

WEB & API TESTING

Assessment of web applications and APIs against the OWASP Top 10 — including REST and GraphQL endpoints for logic flaws, authorisation bypasses, and data leakage.

☁️

CLOUD SECURITY REVIEW

Security posture assessments of Azure, AWS, and M365 tenants against industry benchmarks and best practices to identify and prevent misconfiguration-led breaches.

📲

MDM REVIEW

Comprehensive reviews of Mobile Device Management platforms, including Android and iOS configuration reviews assessed against industry benchmarks.

💳

PCI DSS PEN TESTING

Specialist testing aligned to PCI DSS Requirement 11.4, bridging the gap between technical findings and regulatory pass/fail criteria for cardholder data environments.

💻

BUILD REVIEWS

Deep-dive reviews of Windows Server, Desktop (Gold Image), and network appliances — including desktop breakout testing to identify and close restricted environment bypasses.

🔎

VULNERABILITY SCAN

Credentialed and non-credentialed vulnerability scanning with prioritisation and risk-based reporting to support your internal remediation workflows.

WHO REQUIRES PENETRATION TESTING?

Penetration testing is no longer optional for most regulated organisations. These frameworks either mandate it explicitly or require evidence of regular technical security testing.

💳

PCI DSS

Requirement 11.4 mandates annual internal and external penetration testing of cardholder data environments. Requirement 11.4.3 and 11.4.4 require segmentation testing and targeted testing after significant changes.

🏅

ISO 27001

Annex A control 8.8 requires management of technical vulnerabilities. ISO 27001 auditors expect evidence of regular penetration testing as part of your information security management system.

🏥

NHS DSPT

The NHS Data Security and Protection Toolkit requires organisations handling NHS patient data to evidence regular penetration testing as part of their mandatory annual submission.

🔏

SOC 2 TYPE II

SOC 2 auditors expect penetration testing evidence to support the Security and Availability trust service criteria. Annual testing is standard practice for organisations seeking Type II reports.

⚖️

UK GDPR — ARTICLE 32

Article 32 requires organisations to implement "a process for regularly testing, assessing and evaluating the effectiveness of technical and organisational measures." Pen testing directly satisfies this obligation.

🏢

ENTERPRISE SUPPLY CHAIN

Most FTSE 250 and enterprise procurement processes now require suppliers to evidence annual penetration testing. A current pen test report is increasingly a condition of contract award and renewal.

// Expert-Led Testing

REAL TESTERS. REAL FINDINGS.

Our penetration testing is delivered by highly experienced UK-based security professionals — not automated tools alone. Every engagement is manually led, covering the attack paths that scanners miss.

We work across infrastructure, web applications, cloud environments, mobile device management, and build configurations — adapting our approach to your specific environment and risk profile.

All findings are reported with CVSS-scored severity, clear evidence, and prioritised remediation guidance. A retest can be included to confirm fixes are effective before you close the engagement.

// Our Methodology

HOW WE TEST

Our penetration testing follows industry-standard methodologies including OWASP and PTES (Penetration Testing Execution Standard), adapted to your specific environment and risk profile.

We take a thorough, manual approach — automated scanning alone misses business-logic vulnerabilities and nuanced attack paths that only experienced testers find.

Every report includes a plain-English executive summary alongside the technical detail, so your IT team and your board both understand exactly what was found and what to do about it.

What You Get

  • Detailed technical report with all findings
  • Executive summary for non-technical stakeholders
  • Risk ratings using CVSS industry-standard scoring
  • Clear, prioritised remediation guidance
  • Evidence and proof-of-concept for each finding
  • Retest available to verify fixes are effective
  • 🔍

    RECONNAISSANCE

    Passive and active intelligence gathering about your attack surface.

  • 🧭

    ENUMERATION

    Mapping services, systems and potential entry points in scope.

  • ⚔️

    EXPLOITATION

    Controlled, safe exploitation of identified vulnerabilities to confirm impact.

  • 📈

    POST-EXPLOITATION

    Assessing the impact of a successful breach — data access, lateral movement.

  • 📄

    REPORTING

    Clear, prioritised report with technical detail and executive summary.

  • RETEST

    Verification retest available after remediation to confirm fixes are effective — ask us about including this when scoping.

// FAQ

PENETRATION TESTING FAQ

// Compliance
Several major frameworks mandate penetration testing explicitly or require evidence of regular technical security testing: PCI DSS (Requirement 11.4 — annual internal and external testing of cardholder data environments); ISO 27001 (Annex A 8.8 — technical vulnerability management, with pen testing expected by auditors); NHS DSPT (annual pen test evidence required for organisations handling NHS patient data); SOC 2 Type II (penetration testing evidence supports Security and Availability trust criteria); UK GDPR Article 32 (regular testing of technical measures is a legal obligation); and most enterprise and FTSE supply chain contracts now require a current pen test report as a condition of engagement.
Yes. PCI DSS Requirement 11.4 mandates annual internal and external penetration testing of systems within your cardholder data environment (CDE). Requirement 11.4.4 also requires penetration testing after any significant infrastructure or application changes. Our PCI DSS-aligned testing is specifically scoped to meet these requirements and produces a report formatted for your QSA.
Yes. Article 32 of UK GDPR requires organisations to implement "a process for regularly testing, assessing and evaluating the effectiveness of technical and organisational measures for ensuring the security of the processing." Penetration testing is the most direct and evidenced way to satisfy this obligation. Our reports provide documentation suitable for demonstrating compliance to your DPO, ICO, or auditors.
// The Engagement
Duration depends on scope. A focused web application test typically takes 3–5 days. A full infrastructure engagement may take 1–2 weeks. We agree scope and timelines upfront with no surprises.
We work carefully to minimise disruption. All testing is agreed in advance with defined scope and rules of engagement. We can also conduct testing outside business hours if required.
A vulnerability scan uses automated tools to identify known weaknesses. A penetration test goes further — a skilled tester manually exploits vulnerabilities, chains issues together, and identifies business-logic flaws that scanners miss. Pen testing gives you real proof of exploitability and impact.
A retest can be included in your engagement. Once you have remediated the findings, we re-test the affected areas to confirm the vulnerabilities have been successfully resolved. Ask us about including a retest when scoping your engagement — it can be added to any engagement type.
