Pentest's biggest challenge these days is that businesses cannot measure the effectiveness of Pentester's work, nor can they measure the success of a Pentest campaign. From there, it is not possible to determine whether the return on investment (ROI) is worth it. Understanding those difficulties, CyStack has researched and launched a new Pen-test solution, which can help businesses get the best results with optimal costs.
With the goal of increasing pen-test efficiency, CyStack cooperates with a community of 3000+ security experts, selecting the best pen-testers to implement pen-test projects for customers. We apply a community security model, helping businesses optimize security costs through a bug bounty program.

Pen-testers conduct penetration testing of customers' applications with little or no knowledge of the target (security policy, network infrastructure, software, existing security measures). Blackbox Pentest helps businesses detect risks in the real world that hackers can attack. This is the most common form of Penetration Testing trusted by CyStack's customers.
Gray Box Pen-testing occurs when pen-testers are exposed to partial information about the target (user login information, system architecture, or network overview). Unlike the blackbox pen-test that simulates a normal hacker's perspective, the Graybox pen-test provides the perspective of a hacker who has partially infiltrated the system and knows some sensitive information that is not public.
Pen-testers look for risks in the system under administrator privileges, with access to databases, source code, disclosures of encryption methods, or product structure description documents. Whitebox pen-test helps detect the risk when hackers have the deepest access to the system.
*Report includes detailed descriptions on how vulnerabilities affect business.
