Enables cost-effective security management for small businesses
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.

Tool consistently aids in effective threat detection and monitoring but could benefit from improved log source management and resource optimization
One major area for improvement in LogRhythm SIEM is the lack of volume measurement capability in terms of storage. There is currently no way to determine how much data is being consumed in terms of gigabytes, terabytes, or petabytes from particular devices or environments. This information is crucial for planning future storage needs and scalability. The system monitor (collector) agent has issues with resource consumption. Even when not actively collecting data, the agent continues to consume significant CPU and memory resources, which can be particularly problematic for small business environments with limited resources. LogRhythm SIEM could improve by adding more default device support. While they have good default settings for devices such as Palo Alto firewalls, custom log sources often require extensive work. Increasing the number of supported devices with built-in policies and functionality would reduce the need for custom work. Competitive SIEM tools often provide more comprehensive coverage for various devices and vendors.

Quotes from Members

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

Pros

"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."
"There are a lot of people you will find using OSSIM since they are also offering OTX as a service"
"A very good feature of AlienVault OSSIM is that it has many domains that can be integrated from different solutions."
"Its user-friendliness is the most valuable. It is very easy to use and explore. The dashboard is very well packaged and integrated. You don't have to spend a lot of time in configuring it and checking out the RPM etc. It is also free and very powerful."
"The solution is very stable, and compared to QRadar and Splunk, it's very stable."
"Network traffic analysis is highly efficient."
"The most valuable feature is the logging capability."
"Better than other SIEM solutions because almost everything can be integrated."
"I like LogRhythm's ease of use. The solution has improved compared to previous versions. It had many issues before, like integration, the console, creating reports, false positives, etc. The AI engine has made it stronger in the latest version."
"LogRhythm SIEM's automated response capabilities help organizations mitigate threats through alerts based on specific use cases and monitoring requirements."
"It is a big project, but very worthwhile, and LogRhythm has plenty of documentation, support people, professional services, and classes that can help get a business implemented and push them all the way to completion."
"Overall, versus competitors, it is a lot easier to use, a lot more user friendly, but it still gives you a lot of flexibility to do whatever you want."
"Technical support is very helpful and responsive."
"This solution has been almost like a transformative change in how we detect and then respond to incidence."
"So far we're pretty happy with the overall functionality of the system."
"The product was easy to deploy and easy to learn how to use, and the web console is the best I have seen when compared to other SIEMs."
 

Cons

"The user interface could be improved."
"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."
"It's under heavy traffic. If you have heavy traffic, the system is slow."
"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."
"Lacking in depth of reporting."
"The solution needs more integration with cyber intelligence systems. Our customers want to use a single tool for managing cybersecurity."
"From a management console perspective and the maturity of the dashboards, I would probably put it slightly behind some of the other players that have been in the market for ages."
"There needs to be more focus on the NOC and IIS in terms of developing applications for behavior detection."
"It’s very easy to overwhelm the system. I have some of the beefiest data that they provide, and I can still overrun the system."
"Scalability-wise, it's not that great."
"There are a lot of pieces of it that are very complex and time consuming."
"It seems with all of the advanced features that we haven't quite figured them out. It is very complex."
"The security playbook could be pre-defined and available to other analysts with similar security issues."
"I would like it to do a lot of the automation (which I still need to learn more about), because I am essentially a one man shop doing all the jobs. I'd like for it to be able to do more for me."
"Move it to Linux. I would like to see it get off the SQL Server."
"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."
 

Pricing and Cost Advice

"AlienVault OSSIM is expensive compared to its competitors."
"AlienVault OSSIM is an open-source solution."
"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 tool's licensing costs are yearly."
"The licensing fees for the non-community edition are paid on an annual basis, and there are no costs in addition to this."
"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 the community version, which can be used for free."
"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."
"If you don't have your staff, absolutely look into the co-pilot and factor that into your cost evaluation."
"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 have seen a measurable decrease in the mean time to detect and respond to threats. As it comes out new features and new releases, the window is becoming a lot narrower because you can pivot a lot more with the data. Therefore, the new features and enhancements are reducing that."
"The product is inexpensive than other tools."
"The nice thing about LogRhythm is you can either use the agents, getting a certain number of agents with your license depending on how you want to go, and those agents do a lot of cool things, or you can use CIS Log host, then you have like an unlimited number of them."
"I would recommend that whatever sales quotes to them upfront, they will probably go up. Because they are probably going to outgrow that very quickly or once they start getting everything into it, they are going to have to move up anyway."
"The solution has provided us with consistency and increased staff productivity through orchestrated automated work flows by at least 20 percent."
