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.

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 initial setup was straightforward. I didn't have any problems."
"The threat alerts it gives me from time to time on harmful code within the network, or if they are generating any network traffic, are very useful."
"The paid version of the solution has reporting and better scalability options."
"The dashboard is the solution's most valuable aspect. It brings everything into one central point where I can actually look at it and go, "Okay, I understand what's going on.""
"AlienVault OSSIM's GUI is very user-friendly."
"The threat policies of the solution are always very advanced and the best in the market. They are very persistent in terms of keeping up with security protocols."
"AlienVault OSSIM is an enterprise solution that sells easily. It is rated highly by organizations."
"The initial setup is straightforward."
"What I like most is that the threat models and risk scoring are very accurate and very helpful to the analysts on my team. They help highlight the most important things for them to look at."
"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 reporting in the Securonix Next-Gen SIEM is very good, and the dashboard is great."
"The AI capabilities enhance threat detection."
"The most valuable feature is that it works on user behavior and event rarities."
"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."
"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."
"There aren't any positive aspects of the solution. It was a complete failure. There are no redeeming features."
 

Cons

"AlienVault OSSIM could improve by having better integration with some of the newer tools."
"The incidence reporting could be better."
"There needs to be more support or some kind of training program so users can self-learn the system more effectively."
"It takes some time. It does not give me a prompt response for any such [malicious] traffic. It takes time to get that alert from the AlienVault system."
"I would like the solution to be able to integrate with my firewall, my IDS and my Honeypot solutions so that it can provide real-time reporting as things occur and then have alert sent to me on my phone when suspicious activity is happening."
"AlienVault OSSIM is costly."
"The correlation engine needs to be improved."
"AlienVault OSSIM failed to provide our company a full insight, while also giving out a lot of false positives."
"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."
"Securonix implements risk scores based on different policies that are triggered. We've seen some challenges with the risk scores and how they trigger. These are things that Securonix has recognized and they've been working with us to help improve things."
"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."
"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."
"When dealing with a large amount of data, such as when firewall logs increase, queries sometimes crash or get stuck."
"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."
"One aspect that could be improved is the pricing of the product in Brazil."
"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."
 

Pricing and Cost Advice

"We are using the community version, which can be used for free."
"The solution is open source, so it's free to use."
"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."
"AlienVault OSSIM is free."
"AlienVault pricing is the best. Whatever cost you are paying, you are getting a return on every penny... It's not like your IBM, your QRadar, or Splunk, where the cost is too high."
"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."
"AlienVault OSSIM is expensive compared to its competitors."
"The tool's licensing costs are yearly."
"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."
"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."
"Compared to other brands it seems more affordable to us."
"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."
"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."
"Compared to other known brands in the industry, the overall cost of the licenses is a bit higher than what customers expect."
"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."
