-- Success Click Ltd has announced the release of a guide comparing network segmentation and air gapping strategies for critical infrastructure protection. An industry survey from 2021 found that 83% of critical infrastructure organizations reported experiencing operational technology cybersecurity breaches within the previous 36 months. Security professionals responsible for protecting power grids, water treatment facilities, and transportation systems now have access to a resource that evaluates both isolation methods and their application in high-risk environments.

Air-gapped networks—systems physically or logically isolated from unsecured networks including the public internet—have long been deployed in classified government systems and operational technology environments. However, a May 2026 cybersecurity analysis revealed that traditional air gaps alone no longer provide reliable protection. Modern attack vectors such as infected USB devices, compromised vendor access, and insider threats have successfully breached systems once considered invulnerable, prompting organizations to reconsider how physical isolation fits within broader defense architectures that include logical controls and continuous monitoring.
Network segmentation creates strict internal boundaries between systems based on sensitivity and function. This approach, increasingly integrated with Zero Trust principles and continuous monitoring, allows organizations to reduce operational risk while maintaining necessary connectivity for real-time data access. The guide addresses how segmentation works alongside air gapping to establish multi-layered defense postures, particularly in environments where complete physical isolation proves impractical or operationally restrictive.
The guide provides detailed definitions of both air gapping and network segmentation, outlines specific use cases for each approach, and presents a hybrid model that combines physical and logical isolation. A comparison framework evaluates trade-offs including cost, maintenance complexity, flexibility, and protection levels, enabling critical infrastructure security professionals to assess which strategy—or combination of strategies—aligns with their operational requirements and threat profiles. The resource also examines how air-gapped networks, despite offering superior protection from external cyberthreats, carry higher maintenance costs and limited flexibility compared to segmentation or firewall-based approaches.
The guide aligns with established regulatory frameworks including the Cybersecurity Maturity Capability Model developed by the U.S. Department of Energy. The C2M2 framework provides over 300 cybersecurity practices across 10 domains specifically designed for information technology and operational technology cybersecurity in critical infrastructure sectors, allowing organizations working to meet compliance requirements while implementing effective protection strategies to reference the guide's alignment with these standards to support both security and regulatory objectives.
Gartner's prediction that cyberattackers will weaponize operational technology to cause physical harm by 2025 underscores the urgency of implementing robust defensive measures. As threats evolve to target not just data but physical systems and human safety, critical infrastructure organizations require actionable resources that address both current vulnerabilities and emerging attack methods. The guide provides security professionals with the comparative analysis needed to make informed decisions about isolation strategies, whether deploying pure air gaps, implementing network segmentation, or adopting hybrid approaches that balance security requirements with operational realities.
