CREST Accredited Penetration Testing Company
Introduction:
Working with a CREST Accredited Company helps ensure your security testing is carried out to recognised industry standards by experienced professionals. At CodeShield, we make penetration testing simple. You work directly with a CREST accredited UK pen tester, receiving practical guidance, clear reporting, and real world security insights without unnecessary complexity.
Our goal is straightforward. We help organisations uncover vulnerabilities, strengthen their security posture, and gain confidence in their defences through expert led penetration testing services.
Why Choose a CREST Accredited Security Partner
Not all penetration testing providers operate to the same standards. Choosing a CREST Accredited Company gives your organisation confidence that testing is delivered using recognised methodologies, qualified professionals, and proven processes.
At CodeShield, we focus on identifying genuine risks rather than generating lengthy reports filled with technical jargon. Our testing helps organisations understand where vulnerabilities exist, how they could be exploited, and what actions should be taken to reduce risk.
Working with a CREST accredited security partner provides several benefits:
- Independent security assessments
- Trusted testing methodologies
- Clear and actionable reporting
- Support for compliance requirements
- Assurance for clients, auditors, and stakeholders
- Access to experienced penetration testers
Whether your goal is improving security, meeting regulatory obligations, or preparing for an audit, professional penetration testing provides valuable insight into your organisation’s security posture.
Our CREST Certified Penetration Testing Services
Every organisation has different systems, technologies, and security challenges. That is why CodeShield delivers tailored penetration testing services built around your specific environment.
Web Application Testing
Web applications remain one of the most targeted areas for cyber attacks. Our Web Application Testing service identifies vulnerabilities that could allow attackers to gain unauthorised access, expose sensitive information, or disrupt business operations.
Testing includes:
- OWASP Top 10 vulnerabilities
- Authentication weaknesses
- Authorisation issues
- Business logic flaws
- API security testing
- Session management vulnerabilities
Our assessments provide assurance to clients, stakeholders, and auditors while helping organisations improve application security.
Network Penetration Testing
Our Network Penetration Testing services follow the PTES methodology to assess both internal and external environments.
Testing focuses on:
- Exposed services
- Network configurations
- Patch management
- Security controls
- Internal infrastructure
- External attack surfaces
By simulating realistic attack scenarios, we help organisations understand how attackers may target critical systems and services.
Cloud Security Testing
Cloud environments introduce new security challenges that require specialist expertise. Our Cloud Security Testing service assesses cloud infrastructure and configurations across major platforms.
We test:
- AWS environments
- Microsoft Azure environments
- Google Cloud Platform environments
- Microsoft 365 configurations
- IaaS environments
- PaaS environments
Our testing identifies misconfigurations and security weaknesses across multiple cloud security layers, helping organisations maintain secure and compliant cloud environments.
Adversary Red Teaming
Traditional penetration testing identifies vulnerabilities. Adversary Red Teaming goes further by simulating realistic attack scenarios designed to test people, processes, and technology together.
Our Red Team exercises:
- Simulate real world attacks
- Replicate modern threat actor behaviour
- Test detection capabilities
- Assess response procedures
- Identify security gaps across the organisation
These engagements provide valuable insight into how effectively your organisation can detect and respond to genuine cyber threats.
Social Engineering
Technology is only one part of cybersecurity. People remain a common target for attackers.
Our Social Engineering assessments help organisations evaluate employee awareness and resilience through realistic attack simulations, including:
- Phishing campaigns
- Vishing exercises
- User awareness testing
- Security behaviour assessments
Results can be used to improve security awareness programmes and reduce human related security risks.
Mobile Application Testing
Mobile applications often handle sensitive user data and connect directly to critical backend systems. Our Mobile Application Testing service helps organisations identify weaknesses before they can be exploited.
Testing includes:
- OWASP Mobile Top 10 vulnerabilities
- Android application security
- iOS application security
- API security testing
- Insecure code analysis
- Application logic vulnerabilities
This provides assurance that mobile applications meet modern security expectations.
How CREST Accredited Testing Supports Modern Organisations
Security testing is no longer reserved for large enterprises. Organisations across many sectors rely on penetration testing to strengthen security and support compliance objectives.
CodeShield works with businesses that need to:
- Meet ISO 27001 requirements
- Support PCI DSS compliance
- Prepare for SOC 2 audits
- Meet DSPT obligations
- Demonstrate security assurance to customers

By identifying vulnerabilities before attackers do, organisations can make informed decisions about where to focus security improvements.

"We have used a couple of companies for pen tests in the past, but never had such an outstanding experience. The team really got to grips with our application and took a much more targeted and methodical approach to the testing. Couldn't be happier with the service received."
“We've used a number of CREST assured pen testing companies over the last 10 years, however CodeShield have been the first to exceed my expectations. The team listened to what we wanted, added their own expertise and recommendations and then performed a bespoke test with meaningful, well set out results. The follow-up meetings between our dev team and the testers was well run and respectful. I highly recommend CodeShield and will be engaging them again for our future testing.”
“We had a great experience working with CodeShield. Their team was professional and responsive, and the process was clear, fair, and well-communicated throughout. They also took the time to adjust their solution to better suit our needs. We’re pleased with our decision to work with them and would recommend their services.”
