Effective OT Security with Strong Asset and Vulnerability Visibility **Rating:** 5.0/5.0 stars **Reviewed by:** Metehan E. | Presales Engineer, Small-Business (50 or fewer emp.) **Current User:** The reviewer uploaded a screenshot or submitted the review in-app verifying them as current user. **Validated Reviewer:** Validated through LinkedIn **Incentivized:** This reviewer was offered a nominal incentive as thanks for completing this review. **Source: G2 invite on behalf of seller:** Invitation from G2 on behalf of a seller or affiliate. This reviewer was offered a nominal incentive as thanks for completing this review. **Reviewed Date:** September 16, 2026 **What do you like best about Tenable OT Security?** The combination of passive monitoring and safe, purpose-built active queries enables effective discovery of OT, IT, and IoT assets without disrupting system operations. Compared with traditional OT IDS solutions, the vulnerability detection capabilities are much stronger and provide more actionable information. One of the features I find especially useful is the network map. It provides very good visibility into the environment and makes it easier to understand assets, connections, and communication paths. From a UI/UX perspective, the platform is well organized and relatively easy to navigate. Asset, vulnerability, and network information can be accessed without making the interface feel overly complicated. Performance has also been reliable, even when working with larger amounts of asset and network data. Integration options are another advantage, as they make it easier to connect OT Security with the existing security infrastructure. The initial deployment and onboarding process are also straightforward, and the overall product experience is quite smooth once the environment is configured. **What do you dislike about Tenable OT Security?** There is not much I dislike about the product. I would mainly like to see more customization options for dashboards and reports, especially for different teams and use cases. **What problems is Tenable OT Security solving and how is that benefiting you?** Tenable OT Security helps us continuously identify vulnerabilities across the network without interrupting industrial operations. It also provides valuable capabilities such as Code Revision monitoring, which helps us track changes in OT systems and better understand when configurations or logic are modified. With sensors, we can also collect visibility from isolated or network-segmented ICS environments that are not directly accessible from the main network. In addition, the ability to use agents where appropriate gives us another way to extend visibility. Overall, these capabilities help us reduce blind spots, detect changes and vulnerabilities earlier, and maintain better security visibility across complex OT environments. ### 2. If you cant afford professional service don't buy any Tenable, it just doesn't worth it **Rating:** 0.0/5.0 stars **Reviewed by:** Verified User in Government Administration | Enterprise (> 1000 emp.)

They have asked not to show their name, job title, or picture. **Current User:** The reviewer uploaded a screenshot or submitted the review in-app verifying them as current user. **Validated Reviewer:** Validated through LinkedIn **Incentivized:** This reviewer was offered a nominal incentive as thanks for completing this review. **Source: G2 invite on behalf of seller:** Invitation from G2 on behalf of a seller or affiliate.

They may not have updated their review text, but have updated their review. **What do you like best about Tenable OT Security?** It detects so many things; that's the best part. However, you will have zero support unless you know how to do it yourself by endlessly digging through the entire web and their knowledge base. You're on your own to reinvent the wheel. Without professional service, it is absolutely zero value for your money. **What do you dislike about Tenable OT Security?** It has to be a multi-instance product, and you have an IoT core, a sensor, and a security center. Learning to get a simple report is a nightmare, and their support is nonexistent. They make money from their vendor by selling professional services. Without all this, buying these licenses is an absolute pain. You just waste your few servers, which would sit with tons of data, making no sense. And you get grilled by your superior: why do you even buy it? If you don't have a Tenable superstar on your team, don't buy it; you will regret it and be guaranteed to have to give some acceptable reasons for spending like 100 K $$$ on licenses. I am totally screwed and searching for my value for money. **What problems is Tenable OT Security solving and how is that benefiting you?** It doesn't solve any issue; it's a dumb product that just causes huge pcap storage and traffic on your network. Sensor to ot core to the security center, and as you are air-gapped being OT , it's a pain altogether. And support, and your customer success manager will keep pressuring you to buy professional services, and you would realize you would have been better off buying a managed service rather than paying for licenses. ### 3.

Tenable OT Security does a great job of making complex OT environments visible, understandable, and actionable—which is exactly what most security teams struggle with in industrial settings. **What do you dislike about Tenable OT Security?** While competitive, pricing can feel high for smaller plants what is usual.. Except this none. **What problems is Tenable OT Security solving and how is that benefiting you?** Tenable OT Security is solving a set of very real, day-to-day OT security problems that most organizations struggle with—and the benefits are both operational and strategic. Very good at IT and OT blindspots. I provides Security visibility without risking safety or uptime and passive mpnitoring. ### 5. Unmatched OT Visibility and Fast, Accurate Alerts **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Accounting | Enterprise (> 1000 emp.)

It prioritizes risks with operational context and flags anomalous or unauthorized changes to support segmentation and compliance. The result is fewer blind spots, faster remediation and incident response, reduced downtime risk, and clearer reporting for operations, security, and auditors. ### 6.
