Ravi Shekharan - PeerSpot reviewer
Helped reduce our operational costs and increase our efficiency, but it can be more user-friendly
Regarding the prioritization of threats, Gurucul UEBA needs to enhance its alert severity assignment process within the system. This is one area where Gurucul UEBA could improve. Additionally, it would be beneficial if the tool itself could provide or assign user-based or asset-based CI ratings to allow for a more accurate assessment of alert severity. In our environment, we forward these logs, events, and alerts to SIM, where the CI rating is already present. Therefore, if we need to closely investigate a UEBA case directly, it becomes problematic. Gurucul UEBA should proactively incorporate asset-based or user-based CI severity into its design. Gurucul UEBA needs to be more user-friendly. I would like Gurucul UEBA to be able to integrate with legacy-based identity systems and systems that are performing network-based access control. This would require additional integration and playbook models.

Correlates incidents, allows for quicker identification and helps prioritize investigations
The only challenge is, and that’s where we come into play, it’s a pretty high-tech platform. So, it’s difficult for small and medium-sized organizations to manage it on their own. It’s a very complex system. It requires a lot of expertise. All my guys who work on it have gone through certification from Stellar itself. There are three different certifications that you need to complete. Only then are you certified by Stellar to work on it. It’s a very complex platform. Not everyone can use it. A simple IT engineer or system admin won’t be able to handle it because it’s quite complex. You need to have an understanding of the industry, the subject, and the tool. So, just purchasing this tool or license and then using it on your own would be very difficult to configure and manage on a day-to-day basis. The pricing model is not suitable for small and medium companies, particularly small companies. The minimum pricing model they have is suitable for companies with more than one thousand users. So, if someone has 50 to 100 users, like typical small companies, it’s difficult for them because the cost involved is high. Stellar would charge you for those thousand users, but you do not need all those users. So what are they going to do? I guess Stellar does not want to target small companies directly and maybe relies on resellers and MSPs like us to sell it. So, that is something I would recommend changing. Otherwise, it’s a great tool, but because of the pricing model, small companies are unable to leverage the advantage of this beautiful tool. So, the pricing model should be suitable for small and medium businesses. The product currently has vulnerability monitoring and everything. But if they could also do something about vulnerability management and maybe patch management, that would be nice.
