cyber-physical systems technical

"Modern cyber-physical systems (CPS) are deeply interconnected..."

Cyber-physical systems are networks that link software, sensors, and physical equipment so machines can sense their environment and make real-time decisions—think of a smart thermostat that watches temperature, runs algorithms, and adjusts heating automatically. Investors care because these systems can boost efficiency, create new product capabilities and revenue streams, and change cost structures, but they also introduce risks like hacking, maintenance needs and regulatory scrutiny that can affect profitability and valuation.

IoT technical

"environments (such as OT, ICS, IoT and robotics) have become key CPS tools."

The Internet of Things (IoT) describes a network of everyday devices—such as appliances, vehicles, and equipment—that are connected to the internet and can share data automatically. For investors, IoT represents a growing trend that can drive efficiency and innovation across many industries, potentially creating new opportunities for growth and value. Its expansion influences how companies operate and compete in a digitally connected world.

Magic Quadrant technical

"in the 2026 Gartner® Magic Quadrant™ for CPS Protection Platforms."

A magic quadrant is a two-dimensional chart that places companies in a market into four groups based on how well they perform today and how strong their future plans look; think of it like a map that shows who is leading, who is catching up, who specializes in niches, and who has big ideas but unproven delivery. Investors use it to quickly gauge competitive position, credibility, and potential growth or risk when comparing companies in the same industry.

exposure management platform technical

"The AI-powered Tenable One Exposure Management Platform (Tenable One) delivers a proactive..."

A system that gathers and organizes a company's financial risks and positions—like market moves, credit exposures, or operational vulnerabilities—into a single dashboard so managers can see where money is at risk. Think of it as a household budget app combined with an alarm system: it shows which areas could cause big losses and recommends actions to reduce or hedge those risks. Investors use it to judge how well a company detects, limits and reports potential losses, which affects expected volatility, capital needs and regulatory compliance.

operational technology technical

"proactive security protection for OT environments. A cyber-physical threat..."

Operational technology is the physical equipment and specialized software that directly control machines, sensors and processes in factories, energy grids, transportation systems and buildings — think of it as a facility’s control panel and nervous system. Investors care because problems, upgrades or cyberattacks in this area can halt production, raise costs, require large capital spending, or trigger safety and regulatory issues that affect revenue and valuation.

Tenable One delivers unified visibility, insight and action to secure cyber-physical systems vital to critical infrastructure and industrial operations

COLUMBIA, Md., March 09, 2026 (GLOBE NEWSWIRE) -- Tenable® Holdings, Inc. (NASDAQ: TENB), the exposure management company, today announced that it has been named a Challenger in the 2026 Gartner^® Magic Quadrant™ for CPS Protection Platforms.

According to Gartner, “Cyber-physical systems protection platforms that discover assets and how they connect in product or mission-critical environments (such as OT, ICS, IoT and robotics) have become key CPS tools.” Modern cyber-physical systems (CPS) are deeply interconnected, enabling threats to quickly spread across domains if not properly locked down. Visibility and context-enriched exposure data are mission-critical to preemptive cybersecurity.

The AI-powered Tenable One Exposure Management Platform (Tenable One) delivers a proactive, unified view of risk across IT, cloud, identity and cyber-physical systems. Tenable protects core operations, uncovers blind spots that put organizations at risk, prioritizes action based on business impact and helps security teams stop threats faster. By connecting the dots across domains, Tenable One OT Security offers the most complete view of risk necessary to secure the critical infrastructure underpinning building management systems, manufacturing plants, energy grids, water systems and beyond.

“Tenable has a strong history in delivering proactive security protection for OT environments. A cyber-physical threat is rarely an isolated event—it is an exposure problem that spans the entire attack surface,” said Mark Thurmond, Co-Chief Executive Officer, Tenable. “By integrating OT data into our exposure management platform, we’re eliminating the silos that leave organizations exposed and equipping customers with the comprehensive exposure data and context needed to secure priority risk.”

Gartner also recently named Tenable a Leader in the first-ever 2025 Gartner^® Magic Quadrant™ for Exposure Assessment Platforms¹ and recognized Tenable as the current Company to Beat for AI-Powered Exposure Assessment in the Gartner® report for AI Vendor Race.²
