The point: Modern network security is no longer optional for CISOs, but rather the operational foundation of any effective cyber defense.
Cyberattacks are increasing in frequency and sophistication, amplified by the use of AI. Network infrastructure forms a critical line of defense — but is often still protected with outdated security concepts.
The extent of cyber threats is growing continuously. Attackers increasingly use automated and AI-based methods to explore vulnerabilities and compromise systems. In doing so, they preferentially target network infrastructure — the central passage between attacker and target.
Many organizations lack a contemporary network security strategy. They rely on established perimeter-defense models and firewall technologies that are insufficient for heterogeneous, cloud-native and mobility-driven infrastructure. In this environment, attackers can move laterally through networks and reach sensitive systems.
For CISOs, this means: Comprehensive network security requires segmented architectures, advanced monitoring and continuous anomaly detection. Zero-Trust principles, micro-segmentation and real-time threat intelligence must be implemented as core pillars. Only in this way can network infrastructure be designed as a reliable line of defense.
