Unlike superficial scans, our Network VAPT simulates real-world threats — identifying technical vulnerabilities and translating them into business risk.
White Box testing examines a software's underlying structure, coding, and architecture in order to validate the input-output flow and improve the application's design, security, and utility. Testing of this kind is sometimes referred to as internal testing, clear box testing, open box testing, or glass box testing because testers can see the code.
Black Box, often referred to as behavioral testing or external testing, is a form of software testing technique wherein no prior knowledge of the internal code structure, implementation specifics, or internal routes of an application is necessary. It focuses on the application's input and output and is entirely dependent on the specifications and requirements for the software.
Grey box testing, which combines black box and white box testing, is a software testing approach used to test an application while only having a general understanding of its core code. It searches for and identifies context-specific errors that the application's poor code structure has produced.

Why Leading Businesses Choose Us
"Working with Rex Cyber Solutions changed the way we look at security. They helped us understand how vulnerabilities could directly affect our product roadmap, customer trust, and even our revenue streams. With their clear reporting and hands-on guidance, we were able to fix critical issues and confidently present our security posture to investors during our Series A round. Their support made a real difference."
"Rex was more than just a vendor for us — they acted like an extension of our internal team. What stood out was their ability to simplify complex cybersecurity concepts so even our non-technical leadership could appreciate the risks and fixes. Thanks to their timely support, we cleared both audits and landed a major enterprise client within weeks."
"Before Rex, we had a basic sense that security was important — but we didn’t fully grasp how it tied into customer experience, compliance, and funding. Their team uncovered issues that weren’t just technical flaws but potential blockers to partnerships and regulatory approvals. After working with Rex, we walked into investor meetings with confidence, knowing our security story was strong."
