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 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."
"You can customize the dashboards as well as the reporting."
"The solution is free to use."
"The initial setup is straightforward."
"AlienVault OSSIM's GUI is very user-friendly."
"It has helped us remediate threats in the past by providing significant events that assisted in identifying suspicious activities, such as logins from multiple countries."
"A very good feature of AlienVault OSSIM is that it has many domains that can be integrated from different solutions."
"Most of the SOC or SIEM enterprise class products are very expensive, whereas with OSSIM you can start out with a smaller setup and then expand as you wish."
"We can select the resource group name or functionality directly of which type of security tool logs we want. We don't need to write the query for that; we just have to select."
"In the beginning, we were hesitant to use a new tool, but it soon became our go-to tool for checking and verifying any issues."
"SNYPR is valuable for any organization because it is not only a traditional SIEM, it is also a UEBA tool that does behavior analytics and provides a lot of analytics and visibility in the UI itself."
"The most valuable feature is that it works on user behavior and event rarities."
"The big data security analytics platform, structured and unstructured data analytics, and user and entity behavior analytics provided by the product are probably the best in the industry."
"Once Securonix is operative, it is very powerful."
"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."
"It is an excellent tool that helps us optimize threat-hunting operations, detect intrusive events on the network, and respond to security incidents."
 

Cons

"ArcSight works better than AlienVault right now."
"The main area where the AlienVault product was lacking around the 2018 timeframe was in its ability to scale."
"GUI could be improved."
"The user interface needs to be friendlier across the board."
"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."
"Sometimes it takes very long for your issue to get resolved."
"AlienVault OSSIM failed to provide our company a full insight, while also giving out a lot of false positives."
"When comparing AlienVault OSSIM to other solutions it looks a bit outdated. Additionally, they need to improve their integration."
"There is slight room for improvement in terms of the initial deployment."
"Six months ago, if someone asked me about the support, I would say, "Not good.""
"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 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."
"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 technical support is terrible and completely unhelpful."
"Sometimes, it can become a little overwhelming."
"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 free."
"The tool's licensing costs are yearly."
"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."
"We are using the community version, which can be used for free."
"AlienVault OSSIM is free."
"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 expensive compared to its competitors."
"The solution is open source, so it's free to use."
"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 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."
"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 brands it seems more affordable to us."
"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."
"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."
"The solution's price is double the competitors."
"Compared to other known brands in the industry, the overall cost of the licenses is a bit higher than what customers expect."
