Cisco ASA

Cisco ASA (Adaptive Security Appliance) is a security device used in computer networks to protect against unauthorized access and cyber threats. It acts as a firewall, controlling the flow of data between trusted and untrusted networks, like the internet and an organization's internal systems. In addition to firewall capabilities, ASA also offers features like virtual private network (VPN) support for secure remote access and intrusion prevention to detect and respond to potential attacks. Essentially, it helps ensure that only legitimate traffic enters and leaves a network, safeguarding sensitive information and maintaining operational integrity.
