Security appliances

Security appliances are specialized hardware devices designed to protect computer networks from threats and unauthorized access. They function as gatekeepers, monitoring and controlling data traffic to prevent cyberattacks, viruses, and intrusions. Examples include firewalls, which filter incoming and outgoing traffic, and intrusion prevention systems that detect suspicious activity. These appliances are essential for maintaining the integrity, confidentiality, and availability of network resources, ensuring that sensitive information remains secure while allowing legitimate users to access necessary services efficiently.
