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.

Provides strong detection capabilities but requires improvements in parsing and stability
I cannot think of any specific features that LogRhythm SIEM can improve upon since it supports a wide variety of major vendors. However, they need to improve their parsing techniques; the tool should understand various devices and present data in a human-readable format. For example, if a personal Android mobile needs to be integrated, LogRhythm SIEM should be able to parse that data effectively. They also need to improve their database of supported devices to cover smaller vendors alongside the major players, allowing for better global reach and usability. I have noticed some problems with parsing errors, event mismatches, and data mismatching, so ensuring accurate parsing and continuous improvement according to device updates are my basic expectations as a detection engineer.

Quotes from Members

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

Pros

"The solution is free to use."
"I recommend it due to the experience of the people running it."
"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."
"Technical support is excellent; they are very helpful and responsive."
"The open vault component and the checking of vulnerabilities are the most valuable features, and the page management helps with this, because if you know how your device is vulnerable at least you can do something about it."
"AlienVault OSSIM's GUI is very user-friendly."
"Network traffic analysis is highly efficient."
"The most valuable features of this solution are the data correlation and vulnerability assessment."
"SOAR is integrated with the dashboard that we use for threat management, and because it's all integrated, it is useful for us when we deploy something on-prem."
"I see LogRhythm SIEM as value for money; I would rate it eight out of ten."
"Being able to see when one of our assets is down and being able to restart it really quickly has been a definite benefit."
"The most valuable feature to me is certainly the CloudAI, which I have been a beta tester of, and also the SIEM capabilities and automation."
"This solution has been almost like a transformative change in how we detect and then respond to incidence."
"A lot of customers recommended it, because of the built-in rules, and the out-of-the-box configuration is much better than Splunk, and given our team size and our internal resources, we made the decision to go with LogRhythm."
"We have NetFlow information going into it, so we can examine a lot of traffic patterns and anomalies, especially if something stands out and is not the baseline. This helps a lot."
"In general, the visibility of events and advanced analysis of events are good."
 

Cons

"The solution needs more integration with cyber intelligence systems."
"It does not give me a prompt response for any such malicious traffic; it takes time to get that alert from the AlienVault system."
"The user interface needs to be friendlier across the board."
"There needs to be more support or some kind of training program so users can self-learn the system more effectively."
"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."
"It's under heavy traffic. If you have heavy traffic, the system is slow."
"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."
"I suggest more in-built rules based on modern threats and environments to make it a more competitive solution."
"Stability has probably been one area where Health Checks have not been great with the product. We have been told that they are going to improve Health Checks on product, though we do struggle with them on a daily basis."
"I would like to see more integration with more products that are out there within the same security field."
"The log source support is good, there's always room for improvement. One of the areas that LogRhythm's kind of pushing really hard right now is to integrate more cloud solutions, so your Office 365, your Azure, your AWS, making sure that those SaaS and other cloud platforms are getting the data you need into that platform."
"The reporting on the dashboard should be improved from a management perspective. It would be helpful if they adjusted the colors and the presentation to make things clearer and easier to read."
"They're hard to get a hold of. We've tried to work with a couple of engineering department guys there; we've called them and called them but we never hear anything back."
"There is, of course, always, improved automation. Because, as we are continually needing more and more people from an analyst perspective, the more we can automate, the fewer people we need."
"When we originally got LogRhythm, their tech support was fantastic, and I loved them. Now, we don't quite get as quick of a response."
"Only area I can think of to improve on is the proof reading and using the guides before releasing them. Out the the 20+ guides I used one had issues with wrong information in it."
 

Pricing and Cost Advice

"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 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."
"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."
"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 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."
"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."
"OSSIM is free."
"The tool's licensing costs are yearly."
"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."
"In comparison to the competition, they are more affordable. This allows us to do more with less."
"In the context of our country, the price of this solution is too high."
"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."
"Look for whatever will give you the most value. That's the main point. It is not one size fits all."
"It costs a great amount, but its pricing is competitive with some of the other vendors. For licensing and support, we pay about 20,000. There are no additional costs or anything like that."
"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."
"It is a very cost-effective solution."
