A Proof of Concept (PoC) is a demonstration that shows a proposed idea, technology, or method can work in practice. In cybersecurity, a PoC often refers to a prototype or test that proves a security vulnerability exists or that a security solution is effective. PoCs are used to validate concepts before investing significant time and resources into full development. They help organizations assess feasibility, identify potential challenges, and make informed decisions about moving forward with a project or addressing a security risk.
