Mohammed Nadeem Rais - PeerSpot reviewer
The visibility and analytics from Securonix SIEM have become indispensable in identifying and stopping potential threats before they escalate.
The most valuable feature of Securonix Next-Gen SIEM is its advance analytics, flexibility and scalability. We ingest billions of logs without worrying about resource allocation. This makes it a robust and cost-effective solution for our needs. Its user entity and behavior analytics (UEBA) are also integral for detecting insider threats and lateral movements within the organization. These features help organizations strengthen their security posture, protect sensitive data, and maintain compliance with strict regulatory requirements.

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.

Quotes from Members

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

Pros

"One of the valuable features of Securonix is the auto-incident creation, which was not available two or three years ago."
"The UEBA functionality indicates a lot about behaviors that are not found through a traditional SIEM. We have exploited that more than anything since we started using it."
"I was looking for software as a service rather than having issues with managing hardware, upgrades, updates. I was trying to step away from that. Those were the key factors when looking at Securonix as a full-feature SIEM with next-generation capabilities available."
"They are very updated. Their customer responses are great, and they keep using the new AI tools to keep themselves at the edge of the game."
"The second feature is that within the SNYPR product there is a functionality called Spotter. We use that for link analysis diagrams and to run the stats command. That's extremely useful because it replaces a tedious, manual process we used to use, using Microsoft Excel and a couple of other methods, to bring data together."
"SNYPR has a bundle of features. It has the UEBA feature that tells you about the behavior of a person or entity. In the tool itself, there is an incident management feature, which is definitely valuable."
"The solution has proven to be stable so far...The solution is easy to scale up."
"I find customer service to be very good."
"Stellar Cyber Open XDR offers these functionalities at a more affordable price, making it easier for me to position it with price-sensitive customers."
"It can integrate with almost any cybersecurity tool available in the market."
 

Cons

"It seems to me that within Securonix there is no option for completely visualizing the types of sources or if there is any loss of logs. I've heard that they have an additional module to validate those types of cases, but in terms of the platform itself only, I can only see how often it sends data but not any specific detail."
"Sometimes, the injectors lag and are not loading. It would be nice if that could be improved."
"We have compliance needs. We have investigation needs. And we have situations where an analyst needs to look at threats. These three things require a different view of how they look at the threats. What would be good is to have Securonix create three different views of their Security Command Center so that, depending on the persona of the person logging in, they'd get the relevant data they need and not see everything."
"The incident response area should be improved."
"It takes too long to generate Spotter reports. For example, a 90-day report is around 100 megabytes. That takes a while, but a one-day report can be generated in a few seconds. We would be happy if they sped up the process."
"We look forward to more developments from Securonix Next-Gen SIEM in terms of their service turnaround times and staying connected with customers."
"One aspect that could be improved is the pricing of the product in Brazil."
"Other than issues with the training, there have been issues with the encryption. There have also been issues with some of the reporting, minor glitches that they have fixed as they've gone along."
"Support is an issue because they have a limited number of resources."
"I would rate the stability at about five to six. The platform requires some fine-tuning, especially when integrating data sources and creating connectors."
 

Pricing and Cost Advice

"Its pricing is quite similar to others and is very competitive. The other solutions have different types of licensing, but when you do the math, it is competitive."
"Compared to other brands it seems more affordable to us."
"The solution's price is double the competitors."
"The pricing is good, but by adding more things, the licensing becomes more complex because an EPS license fluctuates a lot. This licensing concept is going to be problematic in the long run."
"Licensing is based on events per second (EPS), costing between $50 to $60 per EPS."
"I had heard that it was much cheaper than Splunk and some of the other tools, and they gave us a nice package with support. They accommodated the number of users and support very well."
"A good thing about Securonix is that they don't charge by volume of data or number of devices... They charge by the number of employees, which is a much more predictable number for me, versus data. Our costs are in the $100,000 range over a three-year subscription."
"I rate the pricing an eight on a scale of one to ten, where one is cheap, and ten is very expensive. It is a pretty expensive tool."
"It’s a single license platform."
