Penetration testing that shows how an attacker would really get in
Our certified ethical hackers attack your applications, infrastructure and AI systems the way a real adversary would — and give you a clear, prioritised plan to fix what they find.

Why pentest
Scanners find issues. Pentesters find the ones that matter.
Automated scanners flag known weaknesses but miss business-logic flaws, chained exploits and authorisation errors — the issues behind most real breaches. A penetration test is a controlled, authorised attack performed by experts to show what an attacker could actually achieve, and how to stop it.
- Identify exploitable vulnerabilities before attackers do
- Provide evidence for ISO 27001, NIS2, DORA, SOC 2 and client security questionnaires
- Validate new releases, migrations and third-party integrations
- Give management a clear, business-level view of technical risk
What we test
Penetration testing services
WEB
Web application testing
Authentication, session management, access control, injection, business logic and data exposure, following the OWASP Web Security Testing Guide.
API
API testing
REST and GraphQL APIs: broken object-level authorisation, mass assignment, rate limiting and token handling (OWASP API Top 10).
MOBILE
Mobile app testing
iOS and Android apps, local storage, transport security and the back-end services they rely on.
NETWORK
External & internal network
Internet-facing perimeter, VPNs and exposed services; internal networks and Active Directory attack paths.
CLOUD
Cloud configuration review
AWS, Azure and Google Cloud: identity, storage, network exposure and misconfigurations.
AI / LLM
AI & LLM penetration testing
Chatbots, assistants and AI agents: prompt injection, data leakage, insecure tool use and jailbreaks (OWASP Top 10 for LLM Applications).
Methodology
How a penetration test works
Scoping
We agree objectives, targets, test type (black, grey or white box), rules of engagement and timing.
Reconnaissance
We map the attack surface: assets, technologies, entry points and exposed information.
Exploitation
Manual testing to identify and safely exploit vulnerabilities and chain them into realistic attack paths.
Reporting
Executive summary plus technical findings with evidence, CVSS severity and remediation guidance.
Retest
Once you have fixed the issues, we retest to confirm they are closed.
Deliverables
What you get
- Executive summary for management: overall risk, key findings and priorities
- Technical report with each vulnerability, evidence, CVSS score and step-by-step fix
- Remediation plan ranked by risk and effort
- Debrief session with your technical team
- Retest and an updated report confirming closed findings
Need proof for a client or auditor? We can provide an attestation letter summarising scope, dates and results.
FAQ
Frequently asked questions
How much does a penetration test cost?
It depends on scope: the number of applications, user roles, endpoints or IP addresses, and the depth of testing. Most web application tests take between 4 and 15 days of work. After a short scoping call we send a fixed-price proposal.
What is the difference between a vulnerability scan and a penetration test?
A scan is automated and lists potential weaknesses. A penetration test is performed manually by experts who verify, exploit and chain vulnerabilities to show real impact — and eliminate false positives.
Will testing disrupt our systems?
Tests are planned with you, follow agreed rules of engagement and avoid destructive actions. Sensitive tests can be run in staging environments or outside business hours.
How often should we test?
At least annually and after significant changes such as new releases, migrations or integrations. NIS2, ISO 27001 and DORA all expect regular testing of security measures.
Can you test AI chatbots and agents?
Yes. We test LLM-based applications for prompt injection, system prompt and data leakage, insecure output handling and abuse of the tools an agent can use, following the OWASP Top 10 for LLM Applications.
