User-friendly interface has improved threat detection through real-time analytics and AI advancements
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. This is very helpful because there are many false positives which keep cropping up, and one of the things that Securonix Next-Gen SIEM does very well is ensuring they don't give attention to false positives. They don't take attention away from the real problems and reduce a lot of noise. We look forward to more developments from Securonix Next-Gen SIEM in terms of their service turnaround times and staying connected with customers.

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 solution has proven to be stable so far...The solution is easy to scale up."
"The most valuable feature is that it works on user behavior and event rarities."
"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."
"Most of our clients are very happy with the solution."
"The solution is stable and scalable."
"The solution is time-saving, particularly in the long run after it is deployed, enabling us to get value promptly."
"One of the most valuable features it has is the thread chaining. One of the common issues that we always had was the number of anomalies that we used to get and the number of alerts that we used to get. But with this approach of thread chaining, we've found the false-positive rate has decreased very significantly. That was something that we never could have achieved before."
"The AI capabilities enhance threat detection."
"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

"Securonix Next-Gen SIEM's deployment is complex and you need a team to do it."
"One of the things they can improve on a little bit is the usability side, to make some things simpler... The tool does have a lot of knobs, you can turn a lot of things on and off and you can change things. Sometimes, it can become a little overwhelming. They should remove some confirmation options and make it simpler for the less mature customers and people who are still trying to grasp it."
"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."
"SIEM could have better integration with other technologies."
"When they did upgrades or applied patches, sometimes, there was downtime, which required the backfill of data. There were times when we had to reach out and get a lot of things validated."
"The incident response area should be improved."
"Six months ago, if someone asked me about the support, I would say, "Not good.""
"Parsing needs to be improved. Every time we integrate a new, specific data source, we face a lot of problems in parsing, even for the old data source."
"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 known brands in the industry, the overall cost of the licenses is a bit higher than what customers expect."
"Licensing is based on events per second (EPS), costing between $50 to $60 per EPS."
"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."
"The pricing is fine compared to the market but I think that at some point the competitors will catch up on price."
"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."
"Its price is fine. We found it to be cheaper than LogRhythm, Exabeam, Splunk, as well as Elastic Security. A few months ago, when we were comparing Securonix with Elastic Security, we found Securonix to be cheaper than Elasticsearch. We were pretty surprised that Elastic Security is more expensive than Securonix because Elasticsearch is just starting, and it cannot compete with Securonix at this time. So, the pricing of Securonix is pretty good for now."
"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."
