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

"A very good feature of AlienVault OSSIM is that it has many domains that can be integrated from different solutions."
"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," and the solution works well and allows me to have visibility into anomalous events."
"AlienVault OSSIM is an enterprise solution that sells easily. It is rated highly by organizations."
"There are a lot of people you will find using OSSIM since they are also offering OTX as a service"
"Inbuilt IDS, inbuilt integration with threat intelligence platform and with vulnerability assessment modules."
"It is a perfectly nice and free tool for compliance testing, assessment, and some basic vulnerability."
"The most valuable features of AlienVault OSSIM are vulnerability assessment, network intrusion detection system, response to critical events, and awareness of the whole network."
"Technical support is excellent; they are very helpful and responsive."
"LogRhythm really gave us a better understanding of what our overall risk is within our network and has opened our eyes to include other products that helped address different types of issues."
"LogRhythm's GUI is easy to explore, and we also like other features, such as its integration with other security solutions, log correlation, and the deployment of use cases."
"The content in the community is very helpful and useful for new users."
"The web interface is awesome, it's very intuitive and gives a lot of great information."
"We have seen a massive increase in the amount of data that we can collect, the type of things that we can see, the way we can look at logs, the way we can get alerts, and the way can create our own customer roles, which has allowed us to customize the work in our environment."
"You can request support and they respond immediately."
"It is a very good solution; it is very robust and very extensive."
"In terms of managing workflows and cybersecurity exposure, LogRhythm SIEM is very efficient and is a good tool to use for locating and auditing any sort of activity that goes on in the network."
 

Cons

"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."
"Lacking in depth of reporting."
"AlienVault OSSIM failed to provide our company a full insight, while also giving out a lot of false positives."
"The initial setup was not so easy, partly because the documentation was not up to date."
"When comparing AlienVault OSSIM to other solutions it looks a bit outdated. Additionally, they need to improve their integration."
"The user interface needs to be friendlier across the board."
"It's under heavy traffic. If you have heavy traffic, the system is slow."
"I suggest more in-built rules based on modern threats and environments to make it a more competitive solution."
"LogRhythm NextGen SIEM is also not as good as IBM QRadar."
"My main thing I'd like to see is, when you're using canned reports, that they're not blank."
"It should have some more message monitoring features. It can also have some free message monitoring tools."
"The main problem I have with LogRhythm SIEM is its stability; the solution is not stable."
"We need to get better training for things like creating code and playlists. The way it's done now takes a long time."
"LogRhythm SIEM can improve its user interface. The current interface is quite complex and can be challenging to navigate. While it offers many valuable features, understanding how to access and utilize them efficiently takes time. Simplifying the client console's user interface would significantly enhance the user experience and make it more user-friendly."
"LogRhythm SIEM needs improvement in data grouping and manipulation capabilities."
"My biggest issue - I know that they say they're doing it - is that the API-building is extremely important. They keep saying it's coming, it's coming. It's not coming fast enough. I don't care if they need to double their team size to get it out there quicker, the world is already in the cloud and we can't monitor it. That's a big problem for us. My boss keeps coming to me about it. That's an issue."
 

Pricing and Cost Advice

"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."
"OSSIM is free."
"The solution is open source, so it's free to use."
"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."
"AlienVault OSSIM is free."
"We are using the community version, which can be used for 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."
"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."
"Everything is expensive with LogRhythm, and you don't get anything for free."
"I would recommend talking to the rep. That's the biggest thing because they will know what questions to ask."
"We did a five-year agreement. We pay close to a quarter of a million dollars for our solution."
"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."
"I have seen a measurable decrease in the mean time to detect and respond to threats. We went from not detecting them to detecting them. We can actually pick up what is anomalous in our network now."
"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."
"It is a very cost-effective solution."
"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."
