Access control is a security measure implemented to regulate and manage who has permission to enter or use specific areas, systems, or resources within a physical or digital environment. It serves as a fundamental component of security systems, ensuring that only authorized individuals or entities are granted access, while unauthorized individuals are denied.

Access control can take various forms, including physical access control for buildings, rooms, and facilities, as well as digital access control for computer systems, networks, and data. The primary goals of access control platform are to seamlessly enhance security, protect sensitive information, prevent unauthorized entry or use, and maintain privacy and confidentiality.

In physical access control, methods like key cards, biometric scans, PIN codes, or security personnel may be employed to verify and authorize entry. In digital access control, user authentication, encryption, and permissions management are key elements in determining who can access specific data or systems.
