An easy-to-scale open-source solution used for monitoring events on devices
The area for improvement is a lot. When I started using it on our enterprise side, the issue we faced was, for example, if we were running at that time on AlienVault OSSIM v5.7.4. So, for some orders, we had to install some packages, and when we tried installing that package, some dependencies got upgraded to a new version. Now once that dependency got upgraded, the SQL, since you might be aware that OSSIM uses SQL database, now SQL and all the dependency in everything was not on the same version, and that caused the database to crash. The aforementioned area should be eased out by upgrading the patches and upgrading dependencies. This kind of thing is a disadvantage of OSSIM, and I would like them to work on this. But I have also raised service requests many times and gave it a push on the community section too. However, since it is a local source, they don't reply much over there. That is why I don't like to work on OSSIM because it is unpredictable. Once the storage goes above 50 percent, it starts behaving unpredictably. If you get stuck with a situation, then you need to drill a lockdown into that. Sometimes you get no luck. Then you have to just reimage the server with the new fresh OS of AlienVault. As for additional features, not much because if you move to the newer version, it is kind of getting more stable. But, to make my life easier, then I would say try to give more features. I know it's open source, so they also cannot provide me with more features. But still, if they can provide me with more features because right now it's becoming old. Right now, we are even moving from SIEM to Security Data Lake. So when we move to it, this will be literally outdated. No one can even expect anything out of it. The way security is moving, it will be outdated very soon. They have to also provide something new to keep this going for the future also.

User-friendly dashboard and machine learning capabilities improve threat hunting efficiency
LogRhythm SIEM has strong machine-learning capabilities with behavioral rules and analysis. The seamless integration for case management, along with a user-friendly dashboard user interface, makes tasks like threat hunting more efficient. Analytics and behavioral analysis help me save time with rule creation. Its scalability allows me to add components as needed. Overall, LogRhythm SIEM offers end-to-end visibility with a reasonable price.

Quotes from Members

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

Pros

"The solution has a very good open source community, and whenever we have problems, we are always able to resolve it online."
"The most valuable features of AlienVault OSSIM are vulnerability assessment, network intrusion detection system, response to critical events, and awareness of the whole network."
"The most valuable features of AlienVault OSSIM are case management, ease of configuration, and investigation."
"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 most valuable feature is the logging capability."
"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."
"The product is majorly used for threat detection of the agents on servers and endpoints."
"The initial setup is straightforward."
"The daily alerts allow me to quickly find security and operations issues which need to be addressed."
"It seems like it will scale easily with the way our environment is set up."
"The GUI is very intuitive and the solution has good integration."
"It gives us insight into our entire installation, where we are multiple sites, going as far as the East Coast to the Central West Coast."
"I find LogRhythm's log management capabilities to be beneficial."
"Its benefits are broad. The solution isn't necessarily made to do any one thing, but it can do anything you tell it to. It is able to tackle any different type or size of job."
"The AI Engine can take an event and correlate it into something else giving us meaningful context regarding what is going on. We integrated it in with our ticketing system, so if an alarm fires, it raises a ticket in our system."
"LogRhythm has increased productivity because all the tools that we need are in the web UI, allowing us to find threats on our network fast and efficiently."
 

Cons

"The initial setup was a bit complex. You've got to do a lot of reading. It's not an intuitive implementation."
"AlienVault OSSIM could improve by having better integration with some of the newer tools."
"I suggest more in-built rules based on modern threats and environments to make it a more competitive solution."
"The correlation engine needs to be improved."
"The price of this solution is very high and it could be cheaper."
"It's so hard to configure and explore something new on it."
"The user interface needs to be friendlier across the board."
"GUI could be improved."
"The built-in functionality of the solution for NDR, SOAR, SIEM, and EDS has room for improvement."
"We would like to see more things out of the console into the web UI. I guess this is what they are doing in 7.4."
"One thing we have mentioned to them before is that we'd like to be able to do searches, or drill-downs, directly from an alarm. When you click it and the Inspector tab slides out, that might be a good place to be able to click the host to search for the last 24 hours. I know the search is right there but it would be even nicer to just click that and then have an option to search something there."
"Parsing is totally controlled by LogRhythm and they do not allow any partner or any third-party to handle this part and this is a key challenge on my end."
"There used to be the ability to create alarms based on message text that was included in LR Version 6.x that has been removed in LogRhythm 7.x, and on that, I would like to see it added back."
"The product's stability needs improvement."
"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."
"We need to get better training for things like creating code and playlists. The way it's done now takes a long time."
 

Pricing and Cost Advice

"AlienVault OSSIM is expensive compared to its competitors."
"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 solution is open source, so it's free to use."
"OSSIM is free."
"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."
"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."
"AlienVault OSSIM is free."
"We are using the community version, which can be used for free."
"In the context of our country, the price of this solution is too high."
"In comparison to the competition, they are more affordable. This allows us to do more with less."
"LogRhythm's pricing and licensing is extremely competitive and it's one of the top three reasons we continue to invest in the platform."
"I would rate the tool's pricing around eight out of ten."
"We work with French-speaking African countries, and it costs more than the average SIEM solution. Also, the pricing isn't too flexible. AlienVault, Splunk, and IBM QRadar are more suitable for customers on a tight budget."
"On a scale of one to ten, I'd rate the pricing of this solution as a seven - not too expensive but not cheap either. Regarding licensing costs, it varies depending on factors like being a partner or an end user, but there are no additional costs aside from standard licensing fees for the basic SIEM solution."
"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 rate the pricing 4 out of 5. There are no additional costs to the standard licensing fees."
