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.

Effective with good log analytics but needs better rule correlation

The correlation rules and log mapping are not as mature compared to other SIM tools like Splunk. Sometimes logs will not fetch, and there are issues if the log volume exceeds a threshold. Not every tool is integrated with Sumo Logic. The response time for their support could be better, and it is not very user-friendly.

Quotes from Members

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

Pros

"The most valuable features of AlienVault OSSIM are case management, ease of configuration, and investigation."

"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 product is majorly used for threat detection of the agents on servers and endpoints."

"The paid version of the solution has reporting and better scalability options."

"The product is easy to use."

"It has helped us remediate threats in the past by providing significant events that assisted in identifying suspicious activities, such as logins from multiple countries."

"The initial setup was straightforward. I didn't have any problems."

"I recommend it due to the experience of the people running it."

More AlienVault OSSIM pros

"The Log Analytics platform is the most effective. If we cannot find the data in other tools, like email security or NDR, we can fetch those logs in the Log Analytics platform of Sumo Logic."

"For many of our services, we use Sumo Logic to track errors and send notifications to our Slack channel, if there are issues. Then, we have our support people monitoring this, and they can react quickly."

"It provides easy visibility. I also like the shareable queries because we share a lot across groups."

"It gives us a bird's eye view of what's happening from our connection's point of view."

"Scalability has been good for our needs. We haven't run into any scaling issues in regards to size so far."

"We have used it many times to find a root cause of a live issue, then fix the problem in the applications."

"We are able to diagnose problems before our customers."

"It helps a lot because we can troubleshoot issues pretty easily."

More Sumo Logic Security pros

Cons

"There needs to be more support or some kind of training program so users can self-learn the system more effectively."

"We need more dashboards and we need more customization for dashboards."

"It's under heavy traffic. If you have heavy traffic, the system is slow."

"The user interface could be improved."

"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 correlation engine needs to be improved."

"The solution needs more integration with cyber intelligence systems."

"The solution is not scalable."

More AlienVault OSSIM cons

"Sumo Logic needs to make sure integrating solutions are seamless."

"The integration with multiple sources could be better."

"I would like better UI-driven functionality to create alerts and reports. Now, we have to understand the syntax, so it is a little difficult for someone to pick it up without using the manuals. If there was more of a graphical user interface, it would be beneficial."

"It would be nice to have an improved ability to scroll through logs within a time frame. Right now, we can search for specific errors. However, if we want to look for "before and after" within a specific time frame, it's not easy using the tool. This would be an improvement."

"If you want to up your subscription through the AWS Marketplace, it can be difficult. You can't just go back to the AWS Marketplace, and say, "I want a bigger one now." You have to contact the sales team, then they do it on the back-end. This could definitely be improved."

"It took a bit of trial and error to get it set up correctly based on everything we had to do. In the end, we had to send everything over HTTP, which was sort of a stop-gap."

"The dashboard has room for improvement, because sometimes it is a difficult to create a specific dashboard or query. This would be a nice place to correct problems."

"I would like to see improvement in the user experience when configuring things, ingesting logs, and creating ports."

Pricing and Cost Advice

"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."

"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."

"AlienVault OSSIM is expensive compared to its competitors."

"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."

"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."

"OSSIM is free."

More AlienVault OSSIM pricing and cost advice

"The pricing is a little high, but for the features that we receive from Sumo Logic, it suits the price. For some small organizations, the price might be a little high."

"The license pricing model is based on the events that are processed through the solution."

"Pricing has been cheaper than some of the competing tools, like Splunk."

"I don't pay the bill. I've heard the AWS Marketplace pricing is high, but I like the value."

"Purchasing the solution through the AWS Marketplace is very easy."

"The AWS Marketplace pricing is fairly reasonable for what it does. I wouldn't call it expensive, but I wouldn't call it cheap. It is pretty good."

"The product is costly."

"Purchasing Sumo Logic through the AWS Marketplace was a simple step."

Overview

AlienVault OSSIM, Open Source Security Information and Event Management (SIEM), provides you with a feature-rich open source SIEM complete with event collection, normalization and correlation. Launched by security engineers because of the lack of available open source products, AlienVault OSSIM was created specifically to address the reality many security professionals face: A SIEM, whether it is open source or commercial, is virtually useless without the basic security controls necessary for security visibility.
