Endpoint security is a method of protecting individual devices that connect to a network, such as laptops, smartphones, tablets, and desktop computers. It involves implementing security measures like antivirus software, firewalls, encryption, and intrusion detection systems to safeguard these endpoints against threats such as malware, unauthorized access, and data breaches. Endpoint security ensures that devices are secure and compliant with organizational security policies, reducing the risk of vulnerabilities being exploited by cybercriminals. Effective endpoint security is critical for maintaining the overall security posture of an organization, as endpoints often serve as entry points for malicious attacks.
