Operators of industrial control systems (ICS) and supervisory control and data acquisition (SCADA) networks are implementing micro-segmentation architectures. Increasing convergence between enterprise IT and operational technology (OT) has expanded surface vectors for targeted ransomware attacks.
Legacy System Constraints
Retrofitting legacy OT devices with zero-trust access protocols requires non-intrusive network proxies, as legacy programmable logic controllers (PLCs) lack local processing headroom for modern encryption overhead.
Regulatory Compliance
Government directives targeting critical infrastructure protection are mandating multi-factor authentication (MFA) and continuous session validation for remote vendor access. Compliance deadlines are driving enterprise spending toward network visibility solutions.
