An open-source solution that provide good detection and more visibility
The solution is not scalable. It impacts so hard. In the initial stages, AlienVault OSSIM can be suitable for small environments. There may be limitations if the customer expresses a desire to expand and add more devices. In such cases, we would need to either explore additional solutions or work within the constraints of the existing setup. We have set up alerts and configured everything in AlienVault OSSIM. It actively monitors for any security incidents. It provides us with regular updates and notifications about any ongoing activities. Only one person is using the solution. It is the perfect solution for small businesses. I rate the solution’s scalability a three out of ten.

User-friendly dashboard and machine learning capabilities improve threat hunting efficiency
LogRhythm SIEM has strong machine-learning capabilities with behavioral rules and analysis. The seamless integration for case management, along with a user-friendly dashboard user interface, makes tasks like threat hunting more efficient. Analytics and behavioral analysis help me save time with rule creation. Its scalability allows me to add components as needed. Overall, LogRhythm SIEM offers end-to-end visibility with a reasonable price.

Quotes from Members

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

Pros

"Inbuilt IDS, inbuilt integration with threat intelligence platform and with vulnerability assessment modules."
"The product is majorly used for threat detection of the agents on servers and endpoints."
"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."
"Better than other SIEM solutions because almost everything can be integrated."
"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."
"The initial setup is straightforward."
"The initial setup was straightforward. I didn't have any problems."
"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.""
"The daily alerts allow me to quickly find security and operations issues which need to be addressed."
"This solution has improved our organization in many different ways. The biggest benefit is being able to view all information in one dashboard instead of having to look at several different applications and dashboards. I can see information across our entire environment and every aspect of our network."
"It supports most standard log sources."
"The most valuable feature of LogRhythm for me is the ability to correlate logs throughout many different log sources."
"Its ability to work with all different sorts of log sources has been extremely valuable."
"What I found most valuable in LogRhythm NextGen SIEM is that it's user-friendly. I also like its dashboard, which shows all the logs and information I want to see."
"It gives us insight into our entire installation, where we are multiple sites, going as far as the East Coast to the Central West Coast."
"The most useful feature that I've found so far is the search function. I like all the different ways you're able to search through metadata and the different ways you're able to correlate or search through logs to find out what's going on."
 

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 main area where the AlienVault product was lacking around the 2018 timeframe was in its ability to scale."
"AlienVault OSSIM’s configuration and integration could be a little easier."
"I suggest more in-built rules based on modern threats and environments to make it a more competitive solution."
"I don't like to work on OSSIM because it is unpredictable."
"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."
"AlienVault OSSIM is costly."
"AlienVault OSSIM should improve the deployment and make it unified like the USM."
"We use Windows Event Forwarding to collect the logs from our Windows clients, and the logs get aggregated as one data source on that collector. Therefore, finding logs specific to one particular Windows system requires some creativity in how we search the SIEM."
"More help and assistance with some of the open source products, everything seems to be focused on Windows versus giving some guidance and some documentation on how to use it."
"One area for improvement in LogRhythm NextGen SIEM is that it's a Windows-based tool, and I feel it should be on the Linux operating system instead. Another area for improvement in the tool is the UI. There should be minor changes in the UI to make it better, though I like the dashboards in LogRhythm NextGen SIEM."
"It should be improved for automated setup and auto-configuration. There should be ease of integration and ease of setup."
"The built-in functionality of the solution for NDR, SOAR, SIEM, and EDS has room for improvement."
"NextGen SIEM's integration with other software is good but could be improved."
"Better integration with different services is needed, as there are quite a few platforms that we use that don't integrate very smoothly with LogRhythm."
"I face stability issues every quarter that necessitate corrective maintenance."
 

Pricing and Cost Advice

"We are using the community version, which can be used for free."
"The licensing fees for the non-community edition are paid on an annual basis, and there are no costs in addition to this."
"OSSIM is free."
"AlienVault OSSIM is expensive compared to its competitors."
"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."
"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."
"The solution is open source, so it's free to use."
"In comparison to the competition, they are more affordable. This allows us to do more with less."
"Look closely at the cost of licensing of other products. This should include setups and the need for support services. I did a RFQ to 2 other vendors before choosing this product."
"It is a very cost-effective solution."
"When it comes time to renew, they say, "This is what you are using. This is what we can do for you." So, they work with you on pricing."
"I would rate the tool's pricing around eight out of ten."
"LogRhythm's pricing and licensing is extremely competitive and it's one of the top three reasons we continue to invest in the platform."
"We work with French-speaking African countries, and it costs more than the average SIEM solution. Also, the pricing isn't too flexible. AlienVault, Splunk, and IBM QRadar are more suitable for customers on a tight budget."
"I would recommend talking to the rep. That's the biggest thing because they will know what questions to ask."
