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

"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."
"There are a lot of people you will find using OSSIM since they are also offering OTX as a service"
"AlienVault OSSIM is an enterprise solution that sells easily. It is rated highly by organizations."
"If you compare with other companies, like LogRhythm, etc., the top 8 or 10 CMs, I think AlienVault has the best price-performance ratio."
"The solution is free to use."
"You can customize the dashboards as well as the reporting."
"OSSIM is the only solution that includes the large number of modules that we need: a vulnerability scanner, a network IDS system, a host IDS system."
"The initial setup is straightforward."
"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."
"I would rate the product a ten out of ten. The solution is very user-friendly and straightforward. The tool's report customization is interesting."
"The GUI is very intuitive and the solution has good integration."
"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."
"In terms of alarms and AI intelligence, we see that LogRhythm is giving more accurate and meaningful events compared to the others."
"LogRhythm's correlation capabilities (part of the AIE component) is much better than Splunk's, and the solution as a whole is generally cheaper and easier to implement than ArcSight."
"It's very easy to create the correlation rules with LogRhythm, and there are some advanced features like SIEM and UEBA, which are also very valuable."
"Its ability to work with all different sorts of log sources has been extremely valuable."
 

Cons

"GUI could be improved."
"It's under heavy traffic. If you have heavy traffic, the system is slow."
"The incidence reporting could be better."
"The solution is not scalable."
"AlienVault OSSIM should improve the deployment and make it unified like the USM."
"The log collection is okay, but tracing the logs or tracing the events is a bit difficult."
"The price of this solution is very high and it could be cheaper."
"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."
"For me, room for improvement is the upgrade process."
"I have had a lot of trouble with stability, perfect timing."
"In terms of improvement, their community boards, where to go find things, as a customer. As they're growing and they're moving stuff around, it would be nice if we knew exactly where to find what."
"I would like to see APIs well-documented and public facing, so we can get to them all."
"Only area I can think of to improve on is the proof reading and using the guides before releasing them."
"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."
"Move it to Linux. I would like to see it get off the SQL Server."
"The built-in functionality of the solution for NDR, SOAR, SIEM, and EDS has room for improvement."
 

Pricing and Cost Advice

"AlienVault OSSIM is free."
"AlienVault OSSIM is expensive compared to its competitors."
"The licensing fees for the non-community edition are paid on an annual basis, and there are no costs in addition to this."
"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."
"The tool's licensing costs are yearly."
"We are using the community version, which can be used for free."
"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."
"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."
"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."
"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."
"If you don't have your staff, absolutely look into the co-pilot and factor that into your cost evaluation."
"NextGen SIEM's pricing is moderate."
"We did a five-year agreement. We pay close to a quarter of a million dollars for our solution."
"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."
