  • Stay informed of emerging threats, zero-days, and advisories relevant to OT (e.g., CISA ICS alerts, ISA/IEC 62443 standards).

Qualifications:

  • 3+ years of experience configuring/implementing Tenable Nessus for enterprises for IT/OT vulnerability assessments.
  • 5+ years of experience with vulnerability management lifecycle and remediation tracking.
  • Nice to have experience in OT/ICS cybersecurity, particularly in sectors such as energy or critical infrastructure.
  • Experience integrating NessTenable with asset discovery and monitoring tools (e.g., Nozomi, Claroty, Dragos, SCADAfence).
  • Experience with Tenable.sc or Tenable.io in hybrid OT/IT environments.
  • Ability to script in Python, PowerShell, or Bash for automation and data processing.
  • Knowledge of ICS protocols (e.g., Modbus, DNP3, BACnet, OPC, Profinet).
  • Familiarity with network segmentation, zone-based architecture, and secure remote access principles in OT.
  • Strong understanding of CVEs, CVSS scoring, and vulnerability lifecycle management.
  • Working knowledge of industry standards and guidelines: ISA/IEC 62443, NIST 800-82, NERC CIP, or equivalent.
  • Strong interpersonal and communication skills to interface effectively with IT, OT, and executive stakeholders.
  • Ability to work in sensitive, safety-critical environments where system availability is paramount.
  • Strong analytical thinking with a detail-oriented and risk-focused mindset.
