Cybersecurity is becoming exponentially more complex. Many organizations are stitching together dozens of disparate solutions trying to enforce policies across network, cloud, and endpoint environments. But this patchwork approach built on a traditional, prevention-only mindset struggles to stop today’s adaptive, AI-enhanced cyber threats. At the same time, cybercrime-as-a-service platforms are reducing the technical barrier to entry, empowering less-skilled adversaries with advanced tools.
From emerging technologies and regulatory pressure to third-party risks, multi-cloud complexity, and widening attack surfaces, the imperative is clear: organizations must shift from cybersecurity as prevention to cyber resilience.
However, that shift is far from easy. According to the WEF’s 2025 Cybersecurity Outlook report, just 14% of organizations believe they have the people and skills needed to meet their security requirements. That’s where infrastructure security (IS) services come in to deliver the foundation and expertise needed to enable cyber resilience at scale.
Cyber resilience accepts that while prevention is necessary, complete immunity is impossible. The goal shifts to maintaining critical business functions, even in the face of compromise, through a continuous cycle of planning, response, and adaptation.
Infrastructure and network security establish the first line of defense that makes this possible. These teams and technologies implement, operate, and maintain the core security controls protecting your hardware, software, networks, and cloud environments.
And the need is urgent. Verizon’s 2025 Data Breach Investigations Report found a 34% year-over-year increase in attackers exploiting known vulnerabilities for initial access. Even more concerning: 46% of perimeter-device vulnerabilities remain unpatched.
Infrastructure and network security create a layered defense that filters malicious traffic, monitors continuously for anomalies, and controls access to resources. If one control fails, others provide backup to ensure detection, containment, and mitigation. This defense-in-depth model aligns with the four core principles of cyber resilience outlined by NIST:
The NIST Cybersecurity Framework (CSF) provides a structured approach with six interrelated functions—identify, protect, detect, respond, recover, and govern—that guide cybersecurity efforts toward resilience.
To reinforce your cyber resilience posture, security leaders should focus on the following high-impact infrastructure strategies:
Avoid reliance on single control points. Deploy overlapping security controls across every layer—from perimeter to endpoint—to catch and contain threats early.
Move beyond perimeter-focused thinking. Zero Trust enforces continuous verification of every user and device—regardless of location—to eliminate implicit trust.
NGFWs provide advanced segmentation, app-aware traffic filtering, and identity-based access control. Firewalls improve both perimeter defense and internal visibility.
Timely updates to software, firmware, and hardware are essential. Combine regular vulnerability scans and pen tests to preempt exploitation.
Use segmentation to isolate critical systems and limit lateral movement—containing breaches and minimizing blast radius in case of compromise.
When you align infrastructure and network security with the NIST CSF, you lay the foundation for enterprise-wide cyber resilience. Security is no longer just a compliance checkbox. It becomes a strategic enabler that supports business continuity, customer trust, and competitive advantage.
Cyber resilience is a journey. It requires ongoing alignment of technologies, processes, and teams to the realities of today’s threat landscape and tomorrow’s business needs.
