FAQ

Common questions about network security.

Clear answers to help you understand network protection, penetration testing, and security monitoring.

Network Security protects the integrity, confidentiality, and availability of computer networks and data. It involves multiple layers of defense at the edge and within the network, including firewalls, intrusion detection/prevention systems, network segmentation, access controls, and continuous monitoring. Our approach combines preventive controls (firewalls, segmentation), detective controls (IDS/IPS, monitoring), and responsive controls (incident response, containment) to protect against unauthorized access, attacks, and data breaches while ensuring business continuity.
