Cyber defence in depth consists of placing several lines of defence consecutively, rather than placing a single line. In recent years, the number of cyber-attacks has exploded. This has jeopardised cyber security efforts, investments and strategies; therefore, adopting a comprehensive cyber defence in depth strategy is becoming increasingly necessary.

This strategy consists of implementing a defensive one in each layer of our critical architecture; where the layer of: Data, Application, Host, Network, Perimeter and Cloud must make use of multiple cybersecurity tools, best practices, processes and regulatory frameworks that support each layer of an architecture to defend itself and, in an integral way, become a secure and robust architecture, which prevents an attacker from affecting the operations of an organisation and reaching its most critical asset; thus damaging its image, reputation or finances.
