GuardsArm Inc doesn’t just identify the problem; they provide solutions. Their reports are the most comprehensive and insightful we’ve ever received—far more detailed than those from a Fortune 50 Pen Test company. They didn’t offer a one-size-fits-all service; instead, they customized their approach to what mattered most to us, delivering valuable, in-depth insights.
GuardsArm Inc performed a web application penetration test on several of our edge applications. They uncovered multiple configuration vulnerabilities, including insecure direct object reference (IDOR). They promptly alerted us and provided guidance on how to resolve the issue. Their expert engineers offered step-by-step support and retested the system to ensure the critical vulnerability was properly addressed.
GuardsArm Inc worked with us to align with our timeline and budget. They customized the Pen Test scope to address our specific needs while staying within our financial constraints.
Wi-Fi security can be tricky to handle. We brought in GuardsArm Inc to test the wireless networks we offer to our employees and customers for accessing store services. The GuardsArm team came onsite with their “toolkit,” complete with antennas sticking out in all directions. They set up a rogue access point to mimic ours, and users unknowingly connected to it. GuardsArm then launched an evil twin attack to intercept and inject packets into the network traffic between user devices and other systems. Afterward, they provided detailed findings, helping us educate our users and adjust their behavior to enhance security.
GuardsArm Inc conducted an external penetration test on our networks and identified critical vulnerabilities. They communicated the potential impact of each vulnerability before attempting to exploit it. We received updates twice a day, which was incredibly helpful for both me and my team. Additionally, they provided excellent remedial guidance, enabling us to quickly address and fix the vulnerabilities.
GuardsArm Inc conducted an internal penetration test on our organization using one of our legacy network protocols. They successfully gained administrative access and were able to deploy malicious code to our network. If this had been a real attack, we could have lost everything.
