Offers strong incident response features but requires more asset visibility and flexibility
Dragos' best features are that they are more focused towards Incident Response, so they have a dedicated playbook in their platform, making it easier for anyone investigating any incidents to investigate the alerts. One of the main features of Dragos is that they have a dedicated Incident Response team, so if clients need any help, they are there to help. Dragos does real-time monitoring as well, collecting mirror traffic from the span port of the switch, and as soon as it gets the traffic, it analyzes it in real time and shows what's going on in the networks, which relates to the real-time visibility feature for ICS networks.

Helps identify vulnerabilities and risks for IT and OT assets
Tenable OT Security is fine, but I find it more language-based rather than structured. It feels like something is on a web page, and the dashboards and data representations are not cool. First of all, I said that the tool view should be improved. It looks pretty old. Second, the details Tenable OT Security provides regarding the metadata they work with should be more in-depth. Its main focus is vulnerability management, which is fine, but what about threat actors? What about attack vectors and OT vulnerabilities? There are major areas, baselines, etc. that need attention.

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Dragos is more expensive than other vendors, probably about fifteen to twenty percent more, but it is generally worth the investment."
"Dragos' best features are that they are more focused towards Incident Response, so they have a dedicated playbook in their platform, making it easier for anyone investigating any incidents to investigate the alerts."
"The biggest advantage is that with good infrastructure, you can utilize asset planning when using Nessus along with Tenable OT Security."
"The product has easy-to-manage features and components."
"The initial setup was very easy, and I would rate it a ten out of ten."
"The product’s price is its most valuable feature."
"The active query inventory is the most valuable feature."
"It's for securing the vulnerability of the OT solutions they are using. We mitigate those through patch management activities and find vulnerabilities easily with this security solution."
"The clear distinction between IT and OT that Tenable OT provides is its most valuable feature."
"I like Tenable OT Security for two main reasons. Firstly, it helps identify vulnerabilities and risks for IT and OT assets, which is crucial for our operations. Secondly, it performs external port scanning, including vulnerability scans for open ports. Compared to the Claroty Platform, the tool offers detailed asset discovery capabilities."
 

Cons

"I think Dragos can offer more flexibility similar to Nozomi and more visibility into the assets, nodes, and links, which would make it more competitive in the future."
"Dragos could improve its asset visibility and discovery tools, as the competitor Claroty has better options in this area."
"As an IT security professional, I would like to see automation improvements in the response part of Tenable OT Security."
"Tenable OT Security is fine, but I find it more language-based rather than structured. It feels like something is on a web page, and the dashboards and data representations are not cool. First of all, I said that the tool view should be improved. It looks pretty old. Second, the details Tenable OT Security provides regarding the metadata they work with should be more in-depth. Its main focus is vulnerability management, which is fine, but what about threat actors? What about attack vectors and OT vulnerabilities? There are major areas, baselines, etc. that need attention."
"The solution should provide more features to prevent attacks."
"Tenable OT product is good, but OT security itself is still maturing."
"As an IT security professional, I would like to see automation improvements in the response part of Tenable OT Security. However, I understand that implementing automation in OT environments can be quite challenging."
"Tenable.ot's integration with one of the products needs improvement."
"During upgrades, the previous configuration may be lost, creating support issues."
"The solution could detect changes in reading variables. The support of IoT devices can be improved."
