An open-source solution that provide good detection and more visibility
The solution is not scalable. It impacts so hard. In the initial stages, AlienVault OSSIM can be suitable for small environments. There may be limitations if the customer expresses a desire to expand and add more devices. In such cases, we would need to either explore additional solutions or work within the constraints of the existing setup. We have set up alerts and configured everything in AlienVault OSSIM. It actively monitors for any security incidents. It provides us with regular updates and notifications about any ongoing activities. Only one person is using the solution. It is the perfect solution for small businesses. I rate the solution’s scalability a three out of ten.
Mahmoud Younes - PeerSpot reviewer
Reliable installation and diverse use cases provide strong value
IBM Security QRadar has some areas for improvement. We have missed some DSM components. We need to customize logs where there is no DSM or connector for certain products. We can integrate but we have missed the DSM, which is the connector to pass logs coming from different applications. For example, with a university customer, we tried onboarding Canvas service. IBM Security QRadar does not support Canvas, so we had to create custom scripts and workarounds to pull logs from Canvas.

Quotes from Members

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

Pros

"The tool's security detection is good. It helps us with login tracking and generating reports. We aim to identify potential issues, such as brute-force attacks on user accounts or server-level anomalies. For instance, if I receive a report indicating a server is at an abnormal level, I investigate and address the issue."
"The most valuable feature is the logging capability."
"AlienVault OSSIM's GUI is very user-friendly."
"With AlienVault you get everything in one box."
"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 threat alerts it gives me from time to time on harmful code within the network, or if they are generating any network traffic, are very useful."
"There are a lot of people you will find using OSSIM since they are also offering OTX as a service"
"The solution has a very good open source community, and whenever we have problems, we are always able to resolve it online."
"The detection rate is good and the false positive rate is low."
"IBM Security QRadar has significantly improved our incident response procedures."
"What I like the most about it is that you can very easily install and configure it. As compared to other SIEM solutions, for which you need to know and do a lot more to prepare your SIEM environment, QRadar is much simpler to install and configure. There are various options in the Admin console. In the Admin tab, you can design dashboards and view various graphs. It has a lot of attractive features, and you don't need to configure everything on your own."
"I have used IBM QRadar User Behavior Analytics in a Cloud Pak on Amazon, and there it runs on top of it and is easy to assess. Additionally, I have installed processes and characters."
"The most valuable features are the versatility of this solution and the variety of things you can do with it."
"The solution is flexible and easy to use."
"Technical support is good overall."
"Integration is very easy and the reporting is good."
 

Cons

"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."
"There needs to be more support or some kind of training program so users can self-learn the system more effectively."
"The price of this solution is very high and it could be cheaper."
"The solution needs more integration with cyber intelligence systems."
"AlienVault OSSIM on-premise version is more difficult to implement than the cloud version. Additionally, they should add integration between several different environments at once and improve their online knowledge base."
"The user interface could be improved."
"It's under heavy traffic. If you have heavy traffic, the system is slow."
"AlienVault OSSIM should improve the deployment and make it unified like the USM."
"We sometimes experience downtime, but it depends on the version. There is some variability."
"The Indian tech support is not helpful."
"Maybe there should be more custom rules in the exchange. Basically, we are using a lot of threat rules, so maybe they'll develop something like that."
"I think that the search speed of this solution could be improved."
"The reporting system could use some upgrading."
"I would also like to see more integration with other vendors. IBM doesn't integrate well with products from China, like Huawei. Many Middle Eastern customers are switching to Huawei from American vendors like Cisco because of the price. In most RFPs, Huawei wins because it costs less."
"There is one problem with QRadar in regards to the add-on apps. The apps can be frustrating. For example, when I add a big app like one of the add-ons for resiliency, add-on applications for QRadar, these applications require different hardware to implement and to deploy. The resiliency connector because there's a considerable amount of data scanning, operates for these apps correctly."
"In terms of additional features, a mobile app would be nice. Also, the reporting is definitely okay, but you have to make sure that everybody with different roles can understand it. There is room for improvement in the reporting."
 

Pricing and Cost Advice

"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."
"AlienVault OSSIM is an open-source solution."
"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 free."
"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."
"The solution is open source, so it's free to use."
"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."
"We are using the community version, which can be used for free."
"Pricing is good."
"Pricing and licensing are competitive. Their new licensing options allow logs to bypass the correlation engine for a flat rate, which is also appealing for log data that is compliance-driven for a small amount of money."
"The solution comes with a high price tag, while some of the competitors provide identical functionality in their offerings at no extra cost."
"When it comes to the initial pricing there can be a huge discount from there side and also I think they are open to competing with other products."
"Licensing is very expensive, IBM QRadar is a very expensive solution. If you want to minimize costs then IBM QRadar is not for you."
"It's too expensive. The licensing is also a little bit difficult to understand because you have to license it per event and per number of flows."
"QRadar UBA's price is a little more than street price and could be reduced."
"You have a one-time payment, and you also can purchase it for one year as a subscription. We have it on-premise, and we have a permanent license for it. We have to pay for the support on a yearly basis. If you compare its cost with Sentinel for one year, QRadar would seem more expensive, but if you compare its cost over five or ten years, Azure Sentinel will be more expensive than QRadar. If you compare its cost with Sentinel for one year, QRadar would seem more expensive, but if you compare its cost over five or 10 years, Azure Sentinel can be more expensive than QRadar."

Questions from the Community

What is your experience regarding pricing and costs for AlienVault OSSIM?
It depends. I would need to review their cost models, but generally, they are on a scaled basis based on throughput usage. Because it's a software as a service solution for their core product for U...

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 implement...
What are the biggest differences between Securonix UEBA, Exabeam, and IBM QRadar?
It mostly depends on your use-cases and environment. Exabeam and Securonix have a stronger UEBA feature set, friendlier GUI and are not licensed based on capacity (amount of logs and information in...
What SOC product do you recommend?
