Assess your cloud app and infrastructure security
Cloud services are an integral part of today’s business landscape, which makes cloud penetration testing fundamental to keeping your business data protected against cyber attacks. The shared responsibility model means security flaws can be introduced silently into your cloud services, putting your business at high risk of a data breach.
Cloud penetration testing uses Bulletproof’s seasoned security testers to rigorously assess the security of cloud infrastructure and applications. Our most common engagements are for GCP, Microsoft 365/Azure, and AWS, where we uncover vulnerabilities, weaknesses and technical misconfigurations that a cyber attacker would target.

Frequently asked questions
Cloud system penetration tests are a comprehensive security review. A qualified tester will attempt to uncover and exploit security vulnerabilities or misconfigurations specific to your cloud network. Cloud penetration testing provides vital information on how to secure your network and, ultimately, helps keep your organisation secure online.
Given that cloud networks are exceptionally attractive to cyber criminals due to the amount of data they hold, regular penetration testing is strongly advised. One or two times a year is usually enough to see how your security perimeters are faring against new attacks and to assess if any new configurations have created security weaknesses within the platform itself. It is also a chance to evaluate if the defences that have previously been put in place, are working effectively.
- Small cloud systems: 1-2 days
- Medium cloud systems: 3-6 days
- Larger cloud systems and multiple cloud accounts:7 days+
All tests are tailored to you so use this as a guide.
We approached Bulletproof as one of several suppliers who offer penetration testing services. Out of all those contacted, Bulletproof were by far the most professional and slick to work with. From start to finish, the whole process was painless and ran like clockwork. The conclusive pen test report was succinct with clear steps of resolution provided. We were genuinely impressed with how easy Bulletproof were to work with, and would definitely recommend.
