Operational Technology & Legacy System Security
The manufacturing industry faces unique security challenges as operational technology (OT) and information technology (IT) converge. Production lines, industrial control systems, and intellectual property are under constant attack. Legacy systems and unpatched vulnerabilities create significant risk.
Rezolute specializes in protecting manufacturing operations with OT/IT segmentation, legacy system hardening, and threat defense tailored to industrial environments.
TOP THREATS TO MANUFACTURING
Operational technology networks converging with IT creates new attack vectors. Traditional IT security controls don't work for OT environments controlling physical production.
Older industrial systems and manufacturing software can't be patched easily. Decades-old systems running on outdated operating systems create persistent vulnerabilities.
Attackers encrypt production systems, shutting down manufacturing. A single ransomware attack can cost millions in downtime and lost production.
Competitors and nation-states target manufacturing intellectual property. Theft of proprietary processes and designs destroys competitive advantage.
Third-party vendors and maintenance contractors with access to production systems can intentionally or unintentionally introduce vulnerabilities.
Supervisory Control and Data Acquisition (SCADA) and Industrial Control Systems (ICS) running outdated firmware and software are widely exploited.
COMPLIANCE & REGULATORY LANDSCAPE
HOW WE PROTECT MANUFACTURING
We assess your operational and information technology networks and implement proper segmentation to isolate OT systems from IT threats while maintaining operational efficiency.
Complete inventory of OT assets, including PLCs, HMIs, and industrial controllers, with network topology mapping.
Architectural design to create secure boundaries between corporate IT and production OT networks.
Implementation of industrial-grade firewalls and access controls tailored to OT protocols.
Legacy systems controlling production can't be easily patched. We implement compensating controls, network segmentation, and alternative security measures to protect unpatched systems.
Comprehensive inventory of legacy industrial systems with vulnerability assessment and risk prioritization.
Deployment of monitoring, segmentation, and access controls to protect unpatchable systems.
Network-level protection to shield legacy systems from known exploits.
We design backup and recovery systems for critical production infrastructure, ensuring business continuity even during security incidents.
Backup systems compatible with industrial control systems and real-time production requirements.
Comprehensive DR plans specifically designed for manufacturing environments.
Specialized IR procedures that account for safety and production continuity.
Third-party access to manufacturing systems is a critical risk. We evaluate and manage vendor security, including maintenance contractors and supply chain partners.
Evaluation of third-party security practices and access controls for manufacturing systems.
Development of comprehensive supply chain security policies and procedures.
Secure remote and on-site access management for maintenance personnel.
