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.

A mature and affordable solution that is easy to install and easy to update
The product takes time to learn, it's not that easy. In the beginning we had a lot of questions. If you want to use such a tool in an real (industrial) environment, you have to ask how to get the network data. Can we do a full packet capture? Can we provide agents to our end systems? There are no simple solutions to these questions. It's a general problem when running such systems in an industrial environment.

Quotes from Members

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

Pros

"SOAR is integrated with the dashboard that we use for threat management. Because it's all integrated, it is useful for us when we deploy something on-prem."
"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."
"Currently, we are in the implementation phase. LogRhythm is better than QRadar from the point of view of collecting Windows events. It has a much higher view. You can enable monitoring by default."
"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."
"The PCI compliance pieces that help us produce reports for our external auditor, and their support."
"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."
"LogRhythm has been really a good partner, they've reached out, they're always wanting information, "How we can improve? How can we do this or that?""
"Technical support has always been helpful."
"Security Onion is the most mature solution in the market."
"We use Security Onion for internal vulnerability assessment."
"The most valuable feature of Security Onion for security monitoring is its ability to find infected ports."
 

Cons

"I work in a highly regulated industry. I know the product has compliance mechanisms, but being able to get more governance surrounding some of the compliance would be helpful."
"I would really love to be able to take some of the data and not have to export it to a CSV file, so I can pull it into Excel to turn it into some other kind of graph."
"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."
"LogRhythm NextGen SIEM is currently based only on the Windows platform. This means that some of our customers have to purchase a Windows license elsewhere. If LogRhythm can move to a Linux platform or a proprietary platform, it would be very helpful."
"We had a little bit of difficulty implementing a disaster recovery situation because it was leveraging only Microsoft native DNS and it wouldn't work with our Infoblox DNS deployment that we use in our environment. They've been working on that behind the scenes."
"Move it to Linux. I would like to see it get off the SQL Server."
"LogRhythm's SOAR and NDR features don't stack up well against competitors. maybe integrating theme functionality as the other do. But in general, it's okay."
"The biggest thing that I think needs improvement is reporting in the Web Console."
"The initial setup of the solution is a little bit difficult."
"The product is not easy to learn."
"Security Onion's user interface could be improved."
 

Pricing and Cost Advice

"In comparison to the competition, they are more affordable. This allows us to do more with less."
"The support which allows more customized to the environment when we are deploying new systems is called Professional Service and is very expensive. The technical annual support and there is an annual fee."
"LogRhythm's licensing is based on MPS. There are some add-on features like advanced UEBA, the cloud component for advanced UEBA, and SIEM."
"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."
"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."
"In the context of our country, the price of this solution is too high."
"I would rate the pricing 4 out of 5. There are no additional costs to the standard licensing fees."
"I think the tool is reasonably priced. There is a need to pay per year towards the licensing costs of the tool."
"It is an open-source solution."
"Security Onion is a free solution."
"Security Onion is an open-source solution."
