Industrial digitization is advancing faster than many imagine. What was once a largely isolated environment (production lines, machines, control systems, etc.) is now connected and therefore exposed. <\/span><\/p>\n We’re talking about<\/span> operational technology, or OT<\/b>, an area where security can no longer be treated as an optional add-on, but as a critical part of the daily operation of any company.<\/span><\/p>\n Some tools stand out, such as Kartos, which provides organizations with a clear, up-to-date, and prioritized view of the cybersecurity risks affecting them. It doesn’t just identify vulnerabilities; <\/span>it helps assess the company’s actual exposure, where the risk lies, and how to reduce it before it is exploited.<\/b><\/p>\n <\/p>\n For decades, operational technology networks operated separately from traditional computer systems. This isolation was, in itself, a layer of security. However, the need to improve efficiency, share data, and remotely control processes has led <\/span>OT systems to be interconnected with IT networks and cloud services.<\/b><\/p>\n IT\/OT convergence offers clear advantages: continuous monitoring, predictive maintenance, energy savings, and reduced downtime. But it introduces a new scenario:<\/span><\/p>\n In this scenario, relying on traditional controls or one-off reviews is no longer enough. <\/span>The exposure changes weekly, sometimes daily.<\/b><\/p>\n You might be interested in<\/span>> IoT and cybersecurity: Risks and strategies to protect connected devices<\/span><\/a>.<\/span><\/p>\n <\/p>\n Operational technology (OT) faces very different risks than those typically found in office computer systems. Here are some of the most common: <\/span><\/p>\n Ransomware attacks are no longer solely focused on stealing or encrypting data. They also aim to paralyze entire factories, disrupt supply chains, or compromise critical equipment. <\/span><\/p>\n Remote access is proper, yes, but it’s often enabled hastily, with weak passwords, or without adequate controls. This is one of the vectors that causes the most incidents in OT environments. <\/span><\/p>\n Many industrial machines are decades old. They’re still working, but they no longer receive security patches. When connected to the network, they become easy targets. <\/span><\/p>\n Even a small, unmonitored open port can serve as a gateway for attackers.<\/span><\/p>\n Suppliers are also part of the OT ecosystem. A security breach in their network can ultimately affect the company as a whole. <\/span><\/p>\n All these factors make it clear that a specific protection strategy is needed for operational technology.<\/span><\/p>\n <\/p>\n The philosophy of proactive cybersecurity is based on<\/span> anticipating risks.<\/b>. It is not enough to react when something goes wrong; we must identify threats before they create a real problem.<\/span><\/p>\n In IT, a failure can lead to data loss or work interruptions. Serious, of course, but manageable. In OT, a failure can halt a production line, generate millions in losses, endanger workers, or affect critical services. <\/span><\/p>\n That’s why<\/span> OT security should aim to prevent incidents from their origin.<\/b><\/p>\n The attackers already know the weaknesses in the operational technology. They are looking for <\/span>old faults, careless configurations, or forgotten access. Even if the company does not install new machines, its exposure may vary due to:<\/span><\/p>\n Supervision must be continuous.<\/b><\/p>\n <\/p>\n The<\/span> Continuous Threat Exposure Management (CTEM) is a framework that has gained traction in recent years. It enables organizations to, on an ongoing basis, understand the risks they face, their potential impact, and the actions to prioritize. <\/span><\/p>\n A well-implemented CTEM strategy in OT helps to:<\/span><\/p>\n This is where solutions like Kartos stand out for their<\/span> comprehensive approach and their ability to continuously monitor exposure <\/b>without interrupting industrial operations.<\/span><\/p>\n <\/p>\n Unlike other tools that focus on<\/span> vulnerability detection<\/span><\/a>, Kartos helps visualize the actual exposure of each asset, supplier, and process connected to the network.<\/span><\/p>\nOperational technology: an industrial environment that is no longer isolated<\/b><\/h2>\n
