Zerothcode delivers integrated security expertise across the four domains: people, assets, locations, and data. Leading organizations around the world from banks, to government agencies, to airports and enterprises, protect their mission-critical operations. The less they are consumed by the fear of attack, the more they can focus on important things like serving customers and citizens, manufacturing products, and innovating. COMPUTER SECURITY Computer security, also known as cyber security or IT security, is the protection of computer systems from the theft or damage to their hardware, software or information, as well as from disruption or misdirection of the services they provide VULNERABILITY ASSESSMENT Vulnerability analysis, also known as vulnerability assessment, is a process that defines, identifies, and classifies the security holes (vulnerabilities) in a computer, network, or communications infrastructure. PENETRATION TESTING Penetration testing (also called pen testing) is the practice of testing a computer system, network or Web application to find vulnerabilities that an attacker could exploit. SYSTEM HARDENING In computing, hardening is usually the process of securing a system by reducing its surface of vulnerability, which is larger when a system performs more functions; in principle a single-function system is more secure than a multipurpose one.
