What does application allowlisting do?

Application allowlisting is a security measure that ensures only approved applications can run on a system or network. This proactive approach significantly reduces the attack surface by preventing unauthorized or potentially harmful software from being executed. By maintaining a list of trusted applications, organizations can mitigate risks associated with malware, zero-day vulnerabilities, and insider threats, as only those applications that have been vetted and deemed safe are permitted to operate. This method is particularly useful in environments where security is paramount, such as in financial institutions or government agencies, as it provides a robust defense against software exploitation and unapproved access to sensitive data.
