Centralized environment supports big data while facing integration challenges
The customization in Securonix Next-Gen SIEM is more difficult compared to other solutions. At the operation level, we are not facing many challenges with automating things using Securonix Next-Gen SIEM, but at the admin level, we have many challenges where log parsing is causing issues and compatibility is not present. The primary technology challenge we have is not at the security tools level. For example, firewall Cisco and others are capable. However, specific to product, for SAP, we are using certain products, and developing custom connectors for each product, especially the internal applications, is difficult, and Securonix Next-Gen SIEM is not up to the mark.

Automated security monitoring increases efficiency, but market visibility needs improvement
I am currently evaluating Stellar Cyber Open XDR in terms of their support. I do not see any major areas for improvement as of now. Their support is good, and the team is small, enabling them to cater to everyone effectively. While I have not encountered significant drawbacks so far, market penetration is challenging due to the product's newness, despite its flexibility and customization features. I find their user interface to be quite good.

Quotes from Members

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

Pros

"We ended up moving our clients over to QRadar as this solution did not end up working for either of them."
"SNYPR is valuable for any organization because it is not only a traditional SIEM, it is also a UEBA tool that does behavior analytics and provides a lot of analytics and visibility in the UI itself."
"Our company very much sees the value in this and, as we move forward, we'll see even more value."
"The detection of threats and reduction of false positive alarms as compared to other solutions are valuable features. It has improved threat detection response and reduced a lot of noise from false positives as compared to our previous SIEM solutions."
"With UEBA being a relatively new space when we looked at it close to two years ago, we were concerned about how well it worked and whether they were truly behavioral-based rules or if that was just marketing terminology for the "latest greatest system," but it exceeds what our initial expectations were for being able to detect different cyber threats."
"The software includes user behavior interactions, dashboards, and training capabilities."
"The most valuable feature is being able to look at users' behavioral profiles to see what they typically access. One of the key events that we monitor is people's downloading of objects... It's very easy to see people's patterns, what they typically do."
"The customizability of the tool is valuable. We are able to customize the use cases and create them easily without a large amount of Securonix assistance. It's very flexible. We do not have to rely on Professional Services to modify or create a new use case."
"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

"Sometimes, it can become a little overwhelming."
"The pricing. I'm not sure how they are proceeding with the identity based pricing compared with DB pricing which most of the vendors are using today."
"The incident response area should be improved."
"Sometimes, there is instability in the data in terms of the customization of the time. They should work on stability on tool."
"The customization in Securonix Next-Gen SIEM is more difficult compared to other solutions. At the admin level, we have many challenges where log parsing is causing issues and compatibility is not present."
"Six months ago, if someone asked me about the support, I would say, "Not good.""
"Support is an area for improvement because it takes a little time for them to attend to tickets."
"The analytics-driven approach for finding sophisticated threats and reducing false positives is positive and good, but the platform requires a more dynamic concept. Everything is a bit static."
"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

"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."
"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."
"We went in on a three-year agreement which has an annual licensing fee, based upon the number of people that we're monitoring. There have not been any additional costs to the standard licensing fees."
"Compared to other known brands in the industry, the overall cost of the licenses is a bit higher than what customers expect."
"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."
"The solution's price is double the competitors."
"We have a license from our 5.0, so that license just continued. We paid them the extra cloud-hosting costs for a year which were about $300,000."
"It’s a single license platform."
