Network Penetration Testing
We simulate external and internal network attacks to identify exposed services, misconfigured devices, weak credentials, and exploitable protocols across your entire network perimeter.
Real-world attack simulations performed by certified security specialists. We expose the weaknesses in your systems, networks, and applications so you can fix them before a threat actor finds them first.
From external network perimeters to internal infrastructure and web applications, our penetration testers assess every layer of your attack surface with precision and rigour.
We simulate external and internal network attacks to identify exposed services, misconfigured devices, weak credentials, and exploitable protocols across your entire network perimeter.
In-depth manual and automated testing of web applications against the OWASP Top 10 and beyond — covering injection flaws, broken authentication, IDOR, business logic vulnerabilities, and more.
Assuming a foothold inside your network, we assess lateral movement possibilities, privilege escalation paths, Active Directory misconfigurations, and internal service vulnerabilities.
We review your AWS, Azure, or GCP configuration for insecure IAM policies, exposed storage buckets, overprivileged roles, and misconfigured services that create exploitable attack paths.
Dedicated testing of REST and GraphQL APIs for broken object-level authorisation, excessive data exposure, rate-limiting gaps, authentication bypasses, and injection vulnerabilities.
We simulate phishing campaigns and pretexting scenarios to measure your organisation's human attack surface — the most frequently exploited entry point in real-world breaches.
A structured, transparent four-step methodology aligned to industry standards — designed to deliver maximum insight with minimum disruption to your operations.
We define the engagement scope, rules of engagement, timelines, and objectives — ensuring full legal authorisation and alignment with your operational requirements.
Passive and active reconnaissance to map your attack surface — identifying hosts, services, technologies, and potential entry points before active exploitation begins.
Manual and tool-assisted exploitation of discovered vulnerabilities within defined scope — demonstrating real business impact with controlled proof-of-concept techniques.
A comprehensive written report with executive summary, technical findings, CVSS severity ratings, proof-of-concept evidence, and prioritised remediation recommendations.
We are offensive security specialists — not generic IT consultants. Every penetration test is conducted with attacker-mindset precision, delivered with professional rigour, and backed by a comprehensive written report.
Our testers think like attackers because they are trained as attackers. We combine automated scanning with deep manual testing to find what automated tools consistently miss.
Every engagement is governed by a signed rules-of-engagement document and NDA. Your findings, systems, and business data remain fully protected throughout the test.
We go beyond CVSS scores — we contextualise every finding against your business environment, so you know exactly which vulnerabilities to fix first and why.
Once you have remediated critical and high severity findings, we offer a retest to verify the fixes hold under the same attack conditions — at no additional cost.
All penetration testing engagements are scoped, managed, and delivered exclusively through our protected client platform — ensuring your systems, findings, and business information remain private, confidential, and professionally handled from day one.
Open Secure Client PortalA representative example of how our web application penetration testing engagement works — from scoping through to critical findings and remediation guidance.
UK-based technology client · Industry: B2B SaaS · Scope: Web application + REST API
A SaaS company required a penetration test ahead of a Series A fundraise. Investors requested evidence of security due diligence. The scope covered the customer-facing web application and all authenticated REST API endpoints.
From your initial request to final report delivery — here is exactly what happens at every stage so you always know where your engagement stands.
You submit your request via our secure portal. We respond within 24 hours to schedule a scoping call, define the target environment, agree on rules of engagement, and issue the NDA and authorisation documentation.
Passive and active recon to enumerate hosts, identify exposed services, map technologies, and build a comprehensive picture of your attack surface before any exploitation activity begins.
Manual and tool-assisted exploitation within the defined scope. All vulnerability findings are documented with proof-of-concept evidence, business impact assessment, and CVSS severity ratings in real time.
A comprehensive written report covering executive summary, full technical findings, prioritised remediation recommendations, and appendices. Delivered to your secure portal with a debrief call if required.
Once you have resolved critical and high severity findings, we retest to confirm the fixes are effective and that no new vulnerabilities were introduced during remediation — included at no additional charge.
Our service commitments & credentials
Many regulatory frameworks and security standards mandate penetration testing as part of ongoing compliance. Our engagements are structured to satisfy these requirements directly.
PCI DSS requires annual penetration testing of cardholder data environments. We structure our engagements to meet the specific requirements of PCI DSS 4.0 Requirement 11.3.
ISO 27001 Annex A includes requirements for technical vulnerability management. Our pen testing reports provide the documented evidence your auditors expect to see.
Cyber Essentials Plus requires hands-on technical verification. We can conduct testing specifically scoped to validate your controls against the Cyber Essentials scheme requirements.
GDPR Article 32 requires appropriate technical security measures. Penetration testing provides documented evidence of your commitment to securing personal data against breaches.
SOC 2 Type II audits require evidence of ongoing security testing. Our structured engagements and detailed reports provide the audit trail your compliance team needs.
Fundraising rounds and M&A due diligence increasingly require recent penetration test reports. We deliver board-ready findings in a format that satisfies investor security questionnaires.
Answers to the most common questions about our penetration testing service, methodology, and what to expect from an engagement.
A vulnerability scan is an automated tool-based process that identifies known weaknesses. A penetration test goes further — a skilled human tester manually attempts to exploit vulnerabilities, chain findings together, and demonstrate real business impact. Pen testing finds what automated tools consistently miss, including logic flaws, authorisation issues, and chained attack paths.
Duration depends entirely on scope and complexity. A focused web application assessment typically requires 3–5 testing days. A full external and internal infrastructure test may require 1–2 weeks. We agree the timeline with you during scoping — before any work or billing begins.
Our testers follow agreed rules of engagement designed to minimise operational risk. For production systems, we typically avoid denial-of-service testing unless explicitly authorised. We can also test against staging environments where disruption is a concern. Any findings that could cause system instability are reported immediately without being exploited further.
You receive a comprehensive written report with an executive summary for non-technical stakeholders, full technical findings with CVSS severity ratings, proof-of-concept evidence for every finding, and prioritised remediation recommendations. A debrief call with our team is available to walk through findings with your development or security team.
Industry best practice and most compliance frameworks recommend at least annual penetration testing. However, you should also test after significant infrastructure changes, major application releases, mergers and acquisitions, or any time you need to satisfy investor or regulatory security requirements. We can help you build a testing cadence that fits your risk profile and budget.
