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

"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."
"The machine-learning algorithms are the most valuable feature because they're able to identify the 'needle in the haystack.'"
"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."
"Its console is very easy to use and configure. It is very intuitive for our use cases. App integrations are also pretty nice."
"We ingest billions of logs without worrying about resource allocation."
"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."
"Risk scoring was nice. We could exactly see which user had the highest risk score, and then we could pick it up and work on it."
"The solution has proven to be stable so far...The solution is easy to scale up."
"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

"Sometimes, there is instability in the data in terms of the customization of the time. I have sometimes observed discrepancies in the data, which is something they should work on. They should bring more stability to time customization. If we are seeing a particular data, when we change the time zone, there should be the same data. There should not be any discrepancy."
"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."
"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."
"One aspect that could be improved is the pricing of the product in Brazil."
"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."
"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."
"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."
"The technical support of the solution is an area with shortcomings and needs improvement."
"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

"The solution's price is double the competitors."
"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."
"Compared to other known brands in the industry, the overall cost of the licenses is a bit higher than what customers expect."
"Compared to other brands it seems more affordable to us."
"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."
"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."
"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."
