"We recently engaged Closed Door Security to conduct external penetration tests on our infrastructure, web applications, and websites across all our group companies at PD&MS. From the outset, the professionalism displayed by the Closed Door Security team was outstanding. Equally important, their team members were incredibly personable, fostering a strong and valuable relationship right from the beginning.

Throughout the entire engagement, Closed Door Security demonstrated a high level of expertise and professionalism. We had two initial meetings where they comprehensively explained the scope of the testing and the expected outcomes. They provided detailed insights into the testing methodologies, the individuals involved in the process, and the timeline for each phase.

Innovative Cyber Security

Our strengths lie in our ability to know how real-world adversaries think and act. We understand how they think, how they might move through a system, and we can counter it as a result.

Our consultants are able to identify potential weaknesses not previously discovered by other teams. We are able to identify certain exploits that may only occur when certain vulnerabilities are chained together.

Our team has years of experience across various avenues in cybersecurity, contributing to the wider community and bringing previously unknown exploits to the collective knowledge base.

Every Step Of The Way

We know our clients may come to us with information that could be damaging or even system-breaking to their day-to-day operations.

We take every step to maintain confidentiality and information sharing is never seen beyond those involved with the assessment.

We use only vetted and approved lines of communication and testing to ensure nothing goes beyond the business, and that no one even knows it’s happening.
