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.

Advanced threat detection has improved investigations but complexity and resource use need refinement
LogRhythm SIEM could learn from Wazuh, as Wazuh has a built-in mechanism that allows you to write custom scripting and scripts through languages that Wazuh can then trigger, which is somewhat better and more matured in Wazuh compared to LogRhythm SIEM. Additionally, the parsers that I write for LogRhythm SIEM tend to get quite complex for log parsing, while with Wazuh, I can achieve a similar parser with much less complexity. Those are some of the pain points that some of our customers have been expressing. If LogRhythm SIEM could make a lightweight version of their solution, that would be quite competitive because some of my customers have a very large need but refuse to go with LogRhythm SIEM due to its complexity and high resource intensity. Therefore, they have been moved to Wazuh, which I am deploying for them. Even though LogRhythm SIEM has extremely good capabilities, their resource utilization is too heavy for certain customers, so if they could make a separate, lightweight version, that would be quite beneficial.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"With AlienVault you get everything in one box."
"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."
"AlienVault OSSIM is an enterprise solution that sells easily. It is rated highly by organizations."
"I have worked with LogRhythm in the past, since 2015, and I find that AlienVault is a better product."
"This solution is very stable; it runs on a Linux box, you only interface with it through the GUI, it works behind the scenes, and it has never crashed in the time that I have used it."
"You pay monthly for the solution. I think it's one of the best products. If you compare with other companies, like LogRhythm, etc., the top 8 or 10 CMs, I think Alien Vault has the best price-performance ratio."
"Network traffic analysis is highly efficient."
"Better than other SIEM solutions because almost everything can be integrated."
"The most valuable features would be the automation, reporting, and the support."
"For us, LogRhythm has given us the kind of insight we need to understand when those threats either are being recon-ed, found out, or when they're really trying a brute force attack to get at us."
"LogRhythm's dashboard is very good compared to other SIEM solutions since it shows many details."
"It allows us to automate a lot of things with a smaller team."
"It has far exceeded what I thought it was going to do for me in my job role."
"Now, the SOC have custom dashboards, showing them a lot more useful information, puts the information in context, and they are actively using it for proactive investigations, rather than just responding to alarms."
"It's the best solution that I've ever used."
"The most valuable feature is scheduling the KB update, which reduces administrative effort."
 

Cons

"The log collection is okay, but tracing the logs or tracing the events is a bit difficult."
"It's so hard to configure and explore something new on it. It is not easy to find the steps we need to follow in order to use the solution effectively."
"When comparing AlienVault OSSIM to other solutions it looks a bit outdated. Additionally, they need to improve their integration."
"The incidence reporting could be better."
"Sometimes it takes very long for your issue to get resolved."
"The solution needs more integration with cyber intelligence systems. Our customers want to use a single tool for managing cybersecurity."
"AlienVault OSSIM on-premise version is more difficult to implement than the cloud version. Additionally, they should add integration between several different environments at once and improve their online knowledge base."
"The user interface needs to be friendlier across the board."
"I would really like to see some type of group or global management for RIM policies,"
"Move it to Linux. I would like to see it get off the SQL Server."
"The initial setup is not so easy because it is quite a process."
"The installation was a bit complex because we are running a virtual infrastructure."
"The built-in functionality of the solution for NDR, SOAR, SIEM, and EDS has room for improvement."
"When we had version 7.2.6, there were a lot of issues deploying that version and with the indexing. The indexer was unstable. So, we were not able to use the platform when we were on that version until we were able to upgrade to 7.3.4."
"The main challenge with setting up LogRhythm is you cannot just put LogRhythm in and let it run."
"My biggest challenge always come back to log sources."
 

Pricing and Cost Advice

"AlienVault OSSIM is expensive compared to its competitors."
"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."
"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."
"OSSIM is free."
"The price of AlienVault OSSIM is too high sometimes for us to present to our customers. The price should be lower. We are on a three-year license to use the solution. We had to pay extra for the support."
"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 the community version, which can be used for 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."
"It is a very cost-effective solution."
"The license cost is around $10 per MPS."
"On a scale of one to ten, I'd rate the pricing of this solution as a seven - not too expensive but not cheap either. Regarding licensing costs, it varies depending on factors like being a partner or an end user, but there are no additional costs aside from standard licensing fees for the basic SIEM solution."
"NextGen SIEM's pricing is moderate."
"The pricing is very reasonable and accessible compared to other products in the market but I am not very sure about the exact licensing cost per year for our company."
"We did a five-year agreement. We pay close to a quarter of a million dollars for our solution."
"In the context of our country, the price of this solution is too high."
"The solution has provided us with consistency and increased staff productivity through orchestrated automated work flows by at least 20 percent."
