OT Cybersecurity Services: Security Without Disruption from Evolvedge Technology Solutions



In today's highly interconnected industrial landscape, the convergence of Operational Technology (OT) and standard information technology is accelerating. While this digital transformation drives unparalleled efficiency, it also exposes critical infrastructure, control systems, and manufacturing environments to new and serious cyber threats.

Evolvedge Technology Solutions specializes in specialized OT cybersecurity services designed to address these risks. The company’s core philosophy, "Security Without Disruption," ensures that necessary security controls are implemented while maintaining the safety, availability, and continuous operation of crucial industrial systems. Evolvedge aligns its services with leading industry standards, including the IEC 62443 framework and NIST SP 800-82.

The Evolvedge portfolio is built upon three main pillars of OT security, supported by robust governance and training programs.

Pillar 1: Secure Remote Access (SRA) for OT Environments

Remote access has become an operational necessity, allowing manufacturers and plant managers to engage external vendors for maintenance, updates, and rapid troubleshooting. However, unmanaged or poorly managed remote access is one of the highest risks to OT networks.

Evolvedge provides comprehensive SRA services to establish vendor-approved remote access architectures that protect networks without impacting production.

Our SRA Services Include:

  • OT Remote Access Architecture Design: Tailored designs for both brownfield and greenfield plants, focusing on IT/OT network segregation using DMZ-based access, jump-host/broker models, and the implementation of Zero Trust principles.

  • Deployment & Configuration: Expert setup of secure gateways and access brokers, implementing robust Multi-Factor Authentication (MFA) enforcement, setting up session recording, and implementing command auditing.

  • Vendor & Third-Party Access Control: Establishing granular, controlled access for Original Equipment Manufacturers (OEMs) and integrators through time-bound, approval-based sessions and the enforcement of least-privilege principles.

  • Secure Remote Access Audit & Hardening: Critical reviews of existing setups, identifying misconfigurations and exposures, policy hardening, and compliance gap mapping.

Supported Technologies:

Evolvedge supports leading SRA solutions, including Secomea, Cyolo Privileged Access for OT, and Zscaler Privileged Remote Access (PRA), as well as integration with PAM (Privileged Access Management) and MFA platforms.

Business Outcomes: Reduced cyber risk, faster troubleshooting capabilities, full visibility and auditability of third-party actions, and compliance-ready access.

Pillar 2: OT Intrusion Detection & Network Visibility (IDS)

Standard IT security tools are often ineffective or dangerous in OT networks, potentially causing critical equipment malfunctions. Evolvedge deploys passive, non-intrusive OT IDS solutions to provide detailed, real-time network visibility and threat detection without disrupting operations.

Our OT IDS Services Include:

  • OT Asset Discovery & Visibility: Passive identification of PLCs, RTUs, HMIs, and DCS units, including their firmware versions, communication protocols, and the identification of any "shadow assets" on the network.

  • Threat Detection & Anomaly Monitoring: Continuous scanning for unauthorized devices, malicious traffic, lateral movement, protocol misuse, and indicators of known ICS-specific malware.

  • OT Network Baseline Creation: Establishing baselines of normal traffic behavior to enable process-aware anomaly detection and subsequent alert tuning to reduce false positives.

  • SOC & SIEM Integration: Integration with established enterprise security operations centers (SOC) for OT-aware alert correlation and incident response workflows.

Supported Platforms:

Evolvedge is expert in deploying leading OT IDS platforms, including Nozomi Networks, Claroty, and Armis, alongside full integration into SIEM/SOC platforms.

Business Outcomes: Full OT network visibility, early detection of cyber threats, significantly improved incident response times, and safe monitoring with zero operational downtime.

Pillar 3: OT Cybersecurity Risk Assessment (IEC 62443)

You cannot protect what you have not quantified. Evolvedge performs structured OT cybersecurity risk assessments aligned specifically with the IEC 62443 standard, ensuring compliance and a clear understanding of practical plant risks.

A Phased Assessment Approach:

Evolvedge utilizes a clear, defined methodology through five phases:

  1. Scope Definition & Asset Identification: Identifying Zones & Conduits, classifying critical assets, analyzing potential impacts on process safety, and establishing a detailed OT system inventory.

  2. Vulnerability Assessment: A thorough scan to identify known and potential security weaknesses.

  3. Risk Analysis & Evaluation: Quantifying the actual risk based on the likelihood and potential consequence of identified vulnerabilities.

  4. Report Generation: compiling technical findings into a cohesive analysis.

  5. Recommendations & Roadmap: The development of a practical, action-oriented plan for mitigating identified risks.

Critical Deliverables:

Clients receive an OT Risk Assessment Report, a detailed IEC 62443 Compliance Gap Matrix, Zone & Conduit Diagrams, a high-level Executive & Technical Summary, and an Actionable Improvement Roadmap.

Supporting Programs: Governance, Training, and Architecture

Evolvedge recognizes that security is about people and processes as much as it is about technology. These supporting services create a cohesive, enduring security program.

Foundational OT Network Segmentation & Zero Trust

Evolvedge designs OT-specific segmentation strategies based on Purdue model alignment. Solutions include VLAN, firewall, and conduit-based isolation to prevent lateral movement and limit the "blast radius" of a potential breach.

OT Governance, Program & Training Development

A robust security posture requires structure and skills. Services include:

  • Governance: OT cybersecurity policy development and incident response planning.

  • Vendor Requirements: Creating and enforcing cybersecurity standards for vendors.

  • Training: Providing tiered training programs, including:

    • OT Security Awareness: For all personnel to recognize common threats.

    • Technical ICS/OT Cybersecurity: Deep-dive technical training for engineers.

    • IEC 62443 & Compliance: Strategic training for security leadership.

Core Competencies & Conclusion

Evolvedge Technology Solutions differentiates itself through:

  • An OT-first cybersecurity approach.

  • Hands-on experience with real, operational plants.

  • Vendor-neutral recommendations.

  • Compliance-driven and risk-based delivery.

  • Capability for remote and onsite global delivery.

Evolvedge serves key industries, including Oil & Gas, Power & Utilities, Mining & Metals, Manufacturing, and Water & Wastewater.
