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.

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

"The feature that is most valuable is the fact that it's an open platform, so it allows us to modify policies and tune policies as needed. There's also a feature called Data Insights which allows us to create different dashboards on specific things of interest for us."
"The machine-learning algorithms are the most valuable feature because they're able to identify the 'needle in the haystack.'"
"The user interface is easy to learn and navigate."
"Our company very much sees the value in this and, as we move forward, we'll see even more value."
"We can now process more data in 20 minutes, it has improved analyst efficiency by 30%, and we haven't experienced any data loss, which is good."
"One of the most valuable features is the integration of all types of data sources to extract relevant information regarding events. It is a good solution when it comes to the correlations that it makes within all the data handled in our company."
"The solution's AI features reduce the need for manual analysis and help in decision-making. It displays the report in seconds. It saves my resources three to four hours of work."
"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."
"It can integrate with almost any cybersecurity tool available in the market."
"Stellar Cyber Open XDR offers these functionalities at a more affordable price, making it easier for me to position it with price-sensitive customers."
 

Cons

"We would like a little more face-to-face training."
"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."
"We would like a little more face-to-face training. Securonix has several tutorials on its website, but we want there to be a person in Colombia who does training or workshops to give us a better understanding of the platform."
"Sometimes, the injectors lag and are not loading. It would be nice if that could 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."
"The incident response area should be improved."
"Sometimes, it can become a little overwhelming."
"The passing and setup are quite complex at the beginning, making onboarding not smooth, which is an area that needs improvement."
"I would rate the stability at about five to six. The platform requires some fine-tuning, especially when integrating data sources and creating connectors."
"Support is an issue because they have a limited number of resources."
 

Pricing and Cost Advice

"The pricing is fine compared to the market but I think that at some point the competitors will catch up on price."
"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."
"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 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 have an annual license. We pay $200,000 for the base licensing and we pay another $50,000 for the software as a service."
"Licensing is based on events per second (EPS), costing between $50 to $60 per EPS."
"The solution's price is double the competitors."
"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."
"It’s a single license platform."
