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.

Tool consistently aids in effective threat detection and monitoring but could benefit from improved log source management and resource optimization
One major area for improvement in LogRhythm SIEM is the lack of volume measurement capability in terms of storage. There is currently no way to determine how much data is being consumed in terms of gigabytes, terabytes, or petabytes from particular devices or environments. This information is crucial for planning future storage needs and scalability. The system monitor (collector) agent has issues with resource consumption. Even when not actively collecting data, the agent continues to consume significant CPU and memory resources, which can be particularly problematic for small business environments with limited resources. LogRhythm SIEM could improve by adding more default device support. While they have good default settings for devices such as Palo Alto firewalls, custom log sources often require extensive work. Increasing the number of supported devices with built-in policies and functionality would reduce the need for custom work. Competitive SIEM tools often provide more comprehensive coverage for various devices and vendors.

Quotes from Members

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

Pros

"The product is majorly used for threat detection of the agents on servers and endpoints."
"The threat policies of the solution are always very advanced and the best in the market, and they are very persistent in terms of keeping up with security protocols."
"Technical support is excellent; they are very helpful and responsive."
"Most of the SOC or SIEM enterprise class products are very expensive, whereas with OSSIM you can start out with a smaller setup and then expand as you wish."
"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."
"Inbuilt IDS, inbuilt integration with threat intelligence platform and with vulnerability assessment modules."
"I have deployed it widely because I find that it gives value for money."
"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."
"Our impression is the solution will be excellent toward meeting our existing security challenges."
"The most useful feature that I've found so far is the search function. I like all the different ways you're able to search through metadata and the different ways you're able to correlate or search through logs to find out what's going on."
"The log analysis feature is valuable."
"Provides visibility into the network."
"Even other products we have that feed into it, instead of having to watch all of them we only have to watch one. For example, we have CrowdStrike, so instead of having to pay attention that solution - because their dashboard doesn't really pop when an alarm comes up - we can see issues with the red on the LogRhythm alarm. That is very nice."
"It supports most standard log sources."
"The fact we're able to create customized monitoring reports that extract info from event logs helps us a lot."
"The visibility that it gives us into all of our data at once."
 

Cons

"When comparing AlienVault OSSIM to other solutions it looks a bit outdated. Additionally, they need to improve their integration."
"GUI could be improved."
"The solution needs more integration with cyber intelligence systems. Our customers want to use a single tool for managing cybersecurity."
"They can add more compliance templates."
"From a management console perspective and the maturity of the dashboards, I would probably put it slightly behind some of the other players that have been in the market for ages."
"I would like the solution to be able to integrate with my firewall, my IDS and my Honeypot solutions so that it can provide real-time reporting as things occur and then have alert sent to me on my phone when suspicious activity is happening."
"The log collection is okay, but tracing the logs or tracing the events is a bit difficult."
"AlienVault OSSIM is costly."
"My big thing is the easability. I don't like to go to two different systems. The fat client that you have to install to configure it, then the web console which is just for reporting and analysis. These features need to collapse, and it needs to be in a single solution. Going through the web solution in the future is the way to do it, because right now, it is a bit cumbersome."
"I wouldn't give them a 10 out of 10 because there is definitely some room for improvement as far as in the GUI."
"What still needs improvement is automation. The SmartResponse obviously does not use open APIs at the moment, so we're having a lot of problems connecting it with things like Palo Alto Traps and some other systems, things like Cisco."
"Functionality, ease of use. There are a few gotchas in the applications."
"I have Windows administrators who will remove the agent when they think that that's what's fouling up their upgrade or their install or their reconfiguration, etc. The first thing they do is to turn off the antivirus, turn down the firewall, and take off anything else. They don't realize that the LogRhythm agent is just sitting there monitoring. Most antivirus products have application protection features built-in where, if I'm an admin on a box, I can't uninstall antivirus. I need to have to the antivirus admin password to do that."
"There are a lot of pieces of it that are very complex and time consuming."
"We're still struggling to get a real return on it and finding something that isn't false noise."
"This product is in general for medium-sized companies. For bigger companies with millions of logs coming in, it just cannot support them."
 

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."
"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."
"AlienVault OSSIM is an open-source solution."
"The tool's licensing costs are yearly."
"AlienVault OSSIM is expensive compared to its competitors."
"The solution is open source, so it's free to use."
"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."
"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."
"It is a very cost-effective solution."
"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."
"LogRhythm's licensing is based on MPS. There are some add-on features like advanced UEBA, the cloud component for advanced UEBA, and SIEM."
"I give the price a six out of ten."
"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."
"When it comes time to renew, they say, "This is what you are using. This is what we can do for you." So, they work with you on pricing."
"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 pricing and licensing is extremely competitive and it's one of the top three reasons we continue to invest in the platform."
