About us

A team working in the field of Offensive Security. At bi0s, we actively research on how to detect and exploit flaws in various networks, cloud appliances and web-based systems. With the main focus on penetration testing and boot2root type CTFs, we actively participate in bug-bounty programs for a real-time bug-hunting experience.

We currently hold ranked fifth in HackTheBox and 80 worldwide and have the main goal of developing industry level pentesting skills to provide the security sector with liable solutions.


Network Pentesting

We analyze networks, systems, hosts and devices like routers to find exploitable vulnerabilities and fix it before it falls to the wrong hands. With priceless experience from bug-bounty programs, we provide suggestions to protect the sensitive data flowing through the network systems.

Cloud Pentesting

As the tech world shifts and more organizations are going serverless and online, most software is moving completely to the cloud. This also makes it difficult to make systems that go hand in hand with security and the required environment. We try to keep up with the ever-changing world of cloud computing while trying to improve them and find flaws.

Web-Based Pentesting

Web application penetration testing is the process of using a methodological series of steps aimed at gathering information about the target system, finding vulnerabilities or faults in them, researching for exploits that will succeed against those faults or vulnerabilities and compromise the web application.
