About Us

Welcome to Red Citadel

Your CREST-accredited partner for penetration testing, cloud security audits and IASME assessments.

Red Citadel is a CREST-accredited penetration testing company providing practical, high-quality cyber security services to companies of all sizes.

Our experienced consultants specialise in penetration testing, cloud security auditing, vulnerability assessments and IASME certification services. We combine technical expertise with clear communication, helping clients understand their risks and make meaningful security improvements.

Throughout every engagement, we work closely with your team, share findings early and provide practical guidance to support remediation. Our focus is not simply on identifying weaknesses, but on helping you strengthen your systems and maintain effective, lasting defences.

Whether you are a small start-up or a large enterprise, we provide thorough, proportionate security services shaped around your systems, objectives and risk profile.

Our Experience​

We are focused on delivering high-quality work and clear value to every client.

Our consultants bring more than twenty years of combined IT and cyber security experience, supported by professional accreditations, qualifications and certifications from CREST, OffSec, Microsoft, Cisco, ISC2, and CompTIA.

Every consultant is employed directly by Red Citadel on a full-time basis, is fully vetted, DBS checked, and a member of the UK Cyber Security Council.

Red Citadel is a CREST member and holds CREST Penetration Testing Accreditation, alongside Cyber Essentials Plus, IASME Cyber Assurance Level Two and IASME Quality Principles certification, demonstrating our commitment to strong information security, effective governance and consistent service quality.

You gain proven expertise, practical insight and the professionalism to support you throughout the engagement, through remediation and beyond the delivery of the final report.

Your Security Treated as Seriously as Our Own

Client information is stored securely within the EEA and is encrypted both in transit and at rest.

Access is tightly controlled through strong role-based access controls and limited to authorised staff who need the information for the engagement. All staff are contractually bound by confidentiality and information security responsibilities.

We do not use artificial intelligence during client engagements or to process client data, whether through external SaaS platforms or locally hosted systems.

Client information is retained only for the short period set out in our Master Service Agreement and is securely deleted at the end of that period.

We maintain a documented incident response process, which is regularly tested and includes client notification and regulatory escalation where required.

Our Mission​

Our mission is to provide high-quality penetration testing, cloud security audits and assurance services that are affordable, practical and straightforward.

By keeping our services clear and client-focused, we make professional cyber security support more accessible without compromising quality, integrity or technical rigour.

We remove the unnecessary complexity that often surrounds cyber security so you can strengthen your defences with greater confidence.

Our penetration testing services start from £750 per day plus VAT, with clear scoping and pricing agreed before work begins.

We provide support throughout the engagement and beyond, helping clients make effective improvements that deliver lasting value.
