IT Services and IT Consulting Irving, Texas 501–1,000 employees Founded 1996 Privately Held

ComTec is a 501–1,000-person IT services firm shifting focus toward operational-technology (OT) security. Their active project list—vulnerability scanning in OT environments, OT network segmentation, asset-vulnerability integration, and OT-specific reporting—combined with hiring in engineering and security roles, reveals a deliberate expansion into industrial cybersecurity. The stack (Nessus, Tenable tools, ServiceNow, AWS) and repeated pain-point focus on minimizing operational impact during scans signals they're solving for a distinct segment: enterprises where downtime costs are measured in production loss, not just dollars.
