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 So when we move to it, this will be literally outdated.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 The way security is moving, it will be outdated very soon.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

Centralized monitoring improves security posture through rapid data processing
The processing part of Elastic Security ( /products/elastic-security-reviews ) is very interesting for us since we handle almost 7,000 to 8,000 alerts per minute. We require rapid processing speed for alerts and event data, and Elastic Security is very efficient at handling this level of data. Additionally, Elastic Security helps improve the security posture of Pakistan through centralized visibility and real-time processing.

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 most valuable features of AlienVault OSSIM are vulnerability assessment, network intrusion detection system, response to critical events, and awareness of the whole network."
"Better than other SIEM solutions because almost everything can be integrated."
"The solution is free to use."
"The paid version of the solution has reporting and better scalability options."
"The solution has a very good open source community, and whenever we have problems, we are always able to resolve it online."
"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."
"AlienVault OSSIM's GUI is very user-friendly."
"Elastic provides the capability to index quickly due to the reverse indexes it offers. This data is crucial as it contains critical information. The reverse index allows fast data indexing because of Elastic's efficient search engine."
"Elastic Security offers advanced features such as machine learning and integration with ChatGPT."
"One of the most valuable features of this solution is that it is more flexible than AlienVault."
"The most valuable feature is the speed, as it responds in a very short time."
"Its flexibility is most valuable. We can have a number of scenarios, and we can get logs from anything. If we know how to use Logstash, we can tweak it in many ways. This makes the logging search on Elastic very easy."
"The most valuable feature for me is Discover."
"Elastic Security helps improve the security posture of Pakistan through centralized visibility and real-time processing."
"The solution has a good community surrounding it for lots of helpful documentation for troubleshooting purposes."
 

Cons

"AlienVault OSSIM could improve by having better integration with some of the newer tools."
"It's so hard to configure and explore something new on it."
"The user interface could be improved."
"When comparing AlienVault OSSIM to other solutions it looks a bit outdated. Additionally, they need to improve their integration."
"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."
"The initial setup was a bit complex. You've got to do a lot of reading. It's not an intuitive implementation."
"We need more dashboards and we need more customization for dashboards."
"I don't like to work on OSSIM because it is unpredictable."
"Sometimes, the solution isn't the easiest to use."
"It would be better if Elastic Security had less storage for data. My customers do not like this. Other vendors have local support in different countries, but Elastic Security doesn't. I would like to have Operational Technology (OT) security in the next release."
"The setup process is complex. You need a solid working knowledge of networking, operating systems, and a little programming."
"If the documentation were improved and made more clear for beginners, or even professionals, then we would be more attracted to this solution."
"The Integration module could be improved. It is a pain to build integration with any product. We have to do parking and so on. It's not like other commercial solutions that use profile integration. I would also see more detection features on the SIEM side."
"We are paying dearly for the guy who is working on the ELK Stack. That knowledge is quite rare and hard to come by. For difficulty and availability of resources, I would rate it a five out of 10."
"They don't provide user authentication and authorisation features (Shield) as a part of their open-source version."
"We'd like better premium support."
 

Pricing and Cost Advice

"AlienVault OSSIM is expensive compared to its competitors."
"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."
"AlienVault OSSIM is an open-source solution."
"AlienVault OSSIM is free."
"We are using the community version, which can be used for free."
"The solution is open source, so it's free to use."
"The tool's licensing costs are yearly."
"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's a monthly cost with Elastic SIEM, but I am not sure of the exact cost."
"Compared to other tools, Elastic Security is a cheaper solution."
"The base product is open-source but if you need advanced security features then you need to pay for the subscription. Elastic Security's price is reasonable in some cases and in other cases it's not."
"Affordable but with additional costs"
"The pricing is in the middle. I think it is not an expensive experience if we compare it with big names, for example, QRadar, and also Oxide. I think Elastic Security is quite cheap. I would rate the pricing of this solution a five out of ten."
"It is easy to deploy, easy to use, and you get everything you need to become operational with it, and have nothing further to pay unless you want the OLED plugin."
"I find it better than Splunk in terms of cost-effectiveness. For cost-effectiveness, I would rate it a nine out of 10."
"The solution is not expensive and costs around ten dollars a month."
