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 So when we move to it, this will be literally outdated.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 The way security is moving, it will be outdated very soon.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.

An automated solution that helped me detect threats in less than half the time it used to take
Sentinel gave us logs to tell us what's going right and wrong in your environment so we could secure the network. We also got multiple kinds of logs. By running some queries from the logs, we could find and fix the anomalies in the environment. Sentinel's threat visibility was great at telling us if we had something going on in our environment. We had to set up alerts in our environment based on the logs. If we had the right alerts set up, we got notified about threats and where security was lacking, so we could also take care of that. Sentinel's threat intelligence helped us prepare and take proactive steps for potential threats before they hit. Having preparation before a threat has helped our security operations. When I was using it, I used to keep going into my dashboards and looking for any threats on a weekly basis, or maybe two or three times a week. Based on that, we would recommend certain changes to the server and infrastructure teams to block or allow some ports. Sentinel's threat intelligence helped plan security against risks.

Quotes from Members

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

Pros

"Inbuilt IDS, inbuilt integration with threat intelligence platform and with vulnerability assessment modules."
"With AlienVault you get everything in one box."
"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.""
"There are a lot of people you will find using OSSIM since they are also offering OTX as a service"
"The initial setup was straightforward. I didn't have any problems."
"The paid version of the solution has reporting and better scalability options."
"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 most valuable feature is the logging capability."
"It makes everything easier by automating some tasks and growing with our needs."
"The most valuable feature is the flexible log for identifying security threats inside an application. Sentinel is very good at this."
"The most valuable feature of this solution is that it provides a central locking system for many event sources."
"The native integration with out-of-the box format is hassle free and allows data to be used advantageously."
"One of the most valuable features is the business intelligence engine. It's very important because it keeps track of everything that's happening and alerts us if something is different than expected. The first time I used it, I was shocked at how well it performed. Another valuable feature that I think makes this product worth the price you pay for it is that it connects to basically every system that provides some form of logging, and it's very easy to set up what triggers this."
"Sentinel gave us logs to tell us what's going right and wrong in your environment so we could secure the network."
"We can do advanced hunting queries and modify SQL queries to get desired results based on the rules triggering over the console."
"The solution lets us get all the logs properly and regularly monitor customer infrastructure."
 

Cons

"There are somewhat more false positives with the user behavior analytics, which could benefit from an additional machine learning model to detect user patterns more rapidly."
"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."
"There are somewhat more false positives with the user behavior analytics, which could benefit from an additional machine learning model to detect user patterns more rapidly."
"I suggest more in-built rules based on modern threats and environments to make it a more competitive solution."
"AlienVault OSSIM should improve the deployment and make it unified like the USM."
"It's under heavy traffic. If you have heavy traffic, the system is slow."
"The solution is not scalable."
"AlienVault OSSIM is costly."
"This product's connection to certain types of cloud systems could be improved. We can do Microsoft, Google, and Amazon, but there are a lot of other things happening in the cloud that we do not connect well enough to. This product could be improved with better connection to cloud-based solutions."
"I would like to see a better reporting work structure on the dashboard."
"Creating a drag-and-drop dashboard or workbook in Sentinel is a little more complex compared to other tools like LogRhythm and IBM QRadar."
"There is no integration in the web-side of the tool."
"There is a need for more flexibility in customization, especially when working with different vendors and platforms."
"The dashboard and customer view should be improved"
"There are still a few vendor-specific devices for which Sentinel needs to work on integration, such as Netskope devices."
"The solution does not allow outsourced authorizations."
 

Pricing and Cost Advice

"AlienVault pricing is the best. Whatever cost you are paying, you are getting a return on every penny... It's not like your IBM, your QRadar, or Splunk, where the cost is too high."
"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."
"We are using the community version, which can be used for free."
"OSSIM is free."
"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."
"The tool's licensing costs are yearly."
"AlienVault OSSIM is free."
"Sentinel is a subscription-based solution."
"We inquired about getting support from the vendor, Micro Focus, but the cost was very high."
"The solution’s pricing is aligned with its competitors."
"Sentinel is moderately priced."
"We receive a pricing discount because of our ongoing partnership with Micro Focus."
"Sentinel's slightly on the expensive side."
