Rajesh Podishetty - PeerSpot reviewer
Manager at a tech vendor with 51-200 employees
Risk monitoring has improved and real-time fraud detection provides transparent banking control
Dragos should be improved in deployment complexity as it requires OT engineering coordination. One needs to have proper engineering coordination to understand the system, deploy it, integrate it, and make all the complex things into one system. This is very challenging, and one should be really skillful and have experience to accomplish this. Cost is another area for improvement. The cost is higher due to site-based licensing and expert services. The licensing is very heavy, and expert services are required for deployment. Cost-wise is also challenging and needs to be improved. Integration needs alignment with IT security systems and compliance frameworks. Controlling cybersecurity where any fraudulent person or third party should not access the system is controlled, and managing that level of complexity is quite challenging. Since there is continuous monitoring, it can reduce operational risk losses by 20% to 30% annually. Controlling that huge amount of data and transactions, especially regarding storage, requires a lot of database space. The space-wise storage should be reduced.

Enables cost-effective asset and threat management while requiring improvements in support and training
The time it takes to train itself is a concern. Initially, it will not identify many assets, as it needs time to read the information before finding the assets. Some detections can go wrong, and it may not understand certain industrial protocols. While installation and deployment are easy, upgrading from one version to another can be challenging. When you assure clients they will receive minus two upgrades, sometimes upgrading through the cloud becomes difficult, requiring on-site upgrades. During upgrades, the previous configuration may be lost, creating support issues.

Quotes from Members

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 especially ensures systems recover quickly, providing resilience, and it handles all the operational resilience in banking with metrics of 99.9% uptime, 30 minutes recovery time, and 99% transaction accuracy."
"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 clear distinction between IT and OT that Tenable OT provides is its most valuable feature."
"The active query inventory is the most valuable feature."
"The biggest advantage is that with good infrastructure, you can utilize asset planning when using Nessus along with Tenable OT Security."
"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 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."
"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

"Dragos could improve its asset visibility and discovery tools, as the competitor Claroty has better options in this area."
"Dragos should be improved in deployment complexity as it requires OT engineering coordination."
"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."
"The solution could detect changes in reading variables. The support of IoT devices can be improved."
"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 product is good, but OT security itself is still maturing."
"The solution should provide more features to prevent attacks."
"During upgrades, the previous configuration may be lost, creating support issues."
"Tenable.ot's integration with one of the products needs improvement."
"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."
