What our clients have said about us

I wouldn’t even look for another supplier. Pricing is consistent and transparent, the team make themselves available for queries at short notice and take a real interest in the work we do to understand our perimeter. Our work with 4ARMED is akin to having a solid friend working in security that you can bounce things off, outside of direct engagements.


Engineering Manager

4ARMED’s knowledge of programming has also helped them identify issues in our code and suggest reasonable remediation steps, which have been gratefully received. The reports delivered at the end of a test are top notch, and have enough technical detail to identify issues and solutions quickly, while still being formatted and worded in such a way as to not confuse the reader.


Developer at SaaS Learning Platform

When we were looking for a penetration testing company most of the companies we dealt with told us the effort required to perform the testing would be very significant and would involve a big learning curve because our testing environment was cloud based and the application lived on top of Kubernetes. 4ARMED were very reasonable and it was clear from the beginning that they were extremely knowledgeable about cloud platforms and Kubernetes.


Systems Engineer at FinTech in Payments, Risk and Compliance

Great communication and overall professionalism. Found several things that previous penetration tests by other companies did not uncover.



We have used many pen-testing companies but have never found one with the deep knowledge of AWS environments. As a company that must maintain security certification 4ARMED are always there to advise.
