Scaling for USM is always challenging for any product unless it is purpose-built or overbuilt at the front end. They will use Palo Alto and its competitors, and LevelBlue will manage that implementation. The main area where the AlienVault product was lacking around the 2018 timeframe was in its ability to scale. By pushing it to a cloud-based system, they've largely alleviated scale issues. It's native in Amazon but will also run in Azure. They have worked with cloud service providers to offer enough throughput at a cost reasonable for a corporation. Scaling was their biggest problem, and they've largely conquered those issues.

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.

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 a very good open source community, and whenever we have problems, we are always able to resolve it online."
"The product is majorly used for threat detection of the agents on servers and endpoints."
"The solution is very stable. Compared to Qradar and Splunk, it's very stable."
"Inbuilt IDS, inbuilt integration with threat intelligence platform and with vulnerability assessment modules."
"Better than other SIEM solutions because almost everything can be integrated."
"The most valuable features of AlienVault OSSIM are case management, ease of configuration, and investigation."
"The most valuable features of this solution are the data correlation and vulnerability assessment."
"AlienVault OSSIM's GUI is very user-friendly."
"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."
"The user interface is easy to learn and navigate."
"There aren't any positive aspects of the solution. It was a complete failure. There are no redeeming features."
"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."
"When we were looking for products for our security monitoring needs, our biggest requirement was that we wanted something based on machine-learning and analytics. If you go with rules, it can raise a lot of noise. Securonix, with its UEBA capability, had the best analytics use-cases."
"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.'"
 

Cons

"There are somewhat more false positives with the user behavior analytics, which could benefit from an additional machine learning model to detect user patterns more rapidly."
"The incidence reporting could be better."
"GUI could be improved."
"It's under heavy traffic. If you have heavy traffic, the system is slow."
"AlienVault OSSIM gives unwanted notifications."
"I don't like to work on OSSIM because it is unpredictable."
"There needs to be more support or some kind of training program so users can self-learn the system more effectively."
"AlienVault OSSIM failed to provide our company a full insight, while also giving out a lot of false positives."
"Regarding the analysis of security events on the SOC side, Securonix Next-Gen SIEM needs to improve its automation capabilities."
"We have a lot of users who, because they're engineers and they're bringing down product data - where, at times, a top-level product could be 10,000 or 15,000 objects - it's difficult for us to determine what should be a concern and what shouldn't be a concern. We work with the Securonix folks to try to come up with better ways to identify that."
"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."
"I face slowness issues sometimes."
"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."
"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."
"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."
"It could be improved a little bit more for admin users. There should be more administrative options related to security for admin users. For example, for forensic purposes, the admin should be able to stop a specific user from erasing some information. I would be helpful in certain situations, such as during an internal fraud."
 

Pricing and Cost Advice

"OSSIM is open source, and USM is the paid license. So, if you want, you can switch to USM. There you will have to buy a license, and they have a support team that helps you out on issues you face."
"When comparing AlienVault OSSIM to Microsoft Sentinel, AlienVault OSSIM incurs additional costs due to its licensing price structure. If you are using AlienVault for security purposes at a certain level it can have a higher price point than the current pricing of Microsoft Sentinel."
"We are using a free version of the solution. If you purchase a license there are more features available but the price is a little high. The solution should be cheaper to allow more customers to be able to afford it."
"AlienVault OSSIM is free."
"AlienVault OSSIM is expensive compared to its competitors."
"AlienVault OSSIM is an open-source solution."
"The solution is open source, so it's free to use."
"I used the paid version of the tool and found it to be expensive. It has been a while since I changed to Securonix. I will have to check whether AlienVault charges per device, user, or log."
"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."
"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."
"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."
"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."
"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."
"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."
