About Us

Welcome to Red Citadel.

Your trusted partner for Penetration Testing, Cloud Security Audits, and Cyber Essentials Assessments.

Here at Red Citadel, we are a collection of experienced ethical hackers that specialise in identifying and reporting security vulnerabilities before malicious actors can exploit them.

Our team of certified ethical hackers brings years of real-world experience to help companies strengthen their cybersecurity posture and be more secure.

By partnering with us, your team gains expert guidance from certified ethical hackers who work alongside you to enhance resilience and maintain strong defences against cyber threats.

Whether you are a small start up or a large enterprise, we deliver thorough penetration testing and auditing services that give you confidence in your security infrastructure.

Our Experience

We are an expert penetration testing company focused on delivering clear value to every client.

Our team brings over twenty years of combined IT and cyber security experience, supported by industry recognised certification bodies including OSCP, CREST, Microsoft, Cisco, ISC2 and CompTIA.

Every consultant holds at least SC level clearance, which is required for roles that involve regular access to secret information.

All staff are members of the UK Cyber Security Council and CREST, both of which set professional standards, promotes ethics and supports the growth of the UK cyber security workforce.

You get a team with proven expertise, real-world insight and the professionalism to support you throughout the engagement and long after the report is delivered to help you stay secure.

Our Mission

We will provide high quality penetration testing, cloud security audits that are affordable and straightforward.

By keeping things simple and client focused, we make security accessible without compromising professionalism, trust or security. We cut the complexity that often surrounds cyber security so you can strengthen your defences with greater confidence.

Our aim is to give you the clarity, confidence and long term support needed to build and maintain a strong security posture.

We offer clear, upfront pricing (£1000 + VAT per day ) and provide support throughout the engagement and beyond.

By combining expertise, accessibility and ongoing guidance, we help companies strengthen their security quickly and effectively, with lasting peace of mind.

Why Choose Us?

Testing built around your needs, not ours.

Mapped to Real-World Threats

Our findings aren’t just CVSS scores.

Where possible, we map each vulnerability to real-world threats, showing how they could be exploited.

By aligning this with your company’s risk appetite and existing knowledge, we help you understand the true impact of vulnerabilities.

This enables your team to prioritise remediation, make informed decisions, and strengthen defences against active attacks.

Agile Delivery of Findings

We don’t wait until testing is complete to deliver results.

We give short daily round-up meetings to share findings of any level of criticality, enabling you to act quickly and efficiently before the final report is produced.

These sessions also help eliminate false positives or misunderstandings that could otherwise unnecessarily bloat the report.

Hands-On Collaboration

We work closely with your team throughout the engagement.

From the initial quote, pre-testing checks, through the testing process, supporting remediation and knowledge transfer every step of the journey.

You’re not just buying a penetration test, you’re buying collaboration and support too

Clear and Actionable Insights

More than just a PDF.

In addition to pre- and post-test support and detailed reports, we provide video proof-of-concepts to demonstrate exactly how vulnerabilities can be exploited in the real world.

This allows you to quickly understand the impact and makes it easier to share findings with internal teams, helping to accelerate development and resolution times.
