Stop managing risk in silos. VM-Native OT Discovery, now available in Tenable Vulnerability Management and Tenable Security Center provides unified visibility across IT and OT domains. See every asset and manage your total cyber exposure in a unified view.<\/h3>\n

Key takeaways<\/h4>\n
    \n
  1. The air gap is dead. IT security teams are inheriting responsibility for operational technology (OT), but often lack visibility into these systems.<\/li>\n
  2. Security teams face significant barriers with OT security. Fear of disrupting fragile devices and the high cost of specialized hardware have created a dangerous “black box” in the attack surface.<\/li>\n
  3. The perfect \u201con-ramp\u201d to OT security. A new OT Discovery engine embedded in Tenable Vulnerability Management and Tenable Security Center allows security teams to safely profile OT, IoT, and shadow IT assets using the tools they already own.<\/li>\n<\/ol>\n

    For decades, the concept of the “air gap” \u2014 a physical isolation between IT networks and critical operational technology (OT) \u2014 provided security leaders with a sense of comfort. The assumption was simple. Digital threats stay on the corporate network, while physical operations run safely in isolation.<\/p>\n

    In today’s hyper-connected world, that assumption is often wrong and leaves your OT environment exposed to preventable cyber risk.<\/p>\n

    From modern data centers and smart hospitals to commercial real estate and universities, the line between the digital and the physical has blurred. IT security teams are increasingly inheriting responsibility for securing cyber-physical systems (CPS) \u2014 the HVAC controllers keeping servers cool, the badge readers securing facility entrances, and the power distribution units keeping the lights on.<\/p>\n

    Yet, for many organizations, these OT assets are a massive blind spot.<\/p>\n

    The “black box” problem<\/h4>\n

    While vulnerability management programs have matured rapidly for IT assets, covering everything from cloud workloads to laptops, operational environments are often a “black box.”<\/p>\n

    This visibility gap usually stems from two distinct barriers:<\/p>\n
