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.

Real-time monitoring and analytics are very easy and fast and very easy to use
The alerting and real-time analytics helped the security team. They are using a Hadoop database, so real-time monitoring and analytics are very easy and fast. Queries return results quickly and in very small time. It has full automation and automated SIEM responses. We are currently only testing Logsign, but in a few months, we plan to integrate our servers, routers, firewalls, and endpoints into our company's Logsign instance. Then, we can manage everything using Logsign.

Quotes from Members

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

Pros

"With AlienVault you get everything in one box."
"Inbuilt IDS, inbuilt integration with threat intelligence platform and with vulnerability assessment modules."
"The initial setup is straightforward."
"Network traffic analysis is highly efficient."
"A very good feature of AlienVault OSSIM is that it has many domains that can be integrated from different solutions."
"I recommend it due to the experience of the people running it."
"The solution is very stable, and compared to QRadar and Splunk, it's very stable."
"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."
"The most valuable features of Logsign SIEM are its cloud capabilities, alerting functionality, integration with Elastic Search, and configuration options."
"Logsign provides sample logs within the product, allowing users to see how logs will appear before integration, which is a valuable feature for testing and understanding log formats."
"It has full automation and automated SIEM responses."
 

Cons

"The main area where the AlienVault product was lacking around the 2018 timeframe was in its ability to scale."
"There needs to be more support or some kind of training program so users can self-learn the system more effectively."
"I don't like to work on OSSIM because it is unpredictable."
"The user interface could be improved."
"The correlation engine needs to be improved."
"When comparing AlienVault OSSIM to other solutions it looks a bit outdated. Additionally, they need to improve their integration."
"The incidence reporting could be better."
"The price of this solution is very high and it could be cheaper."
"AI and machine learning need to be developed. If they develop those features, I think everything will be fine."
"I hope they address the pricing model for Logsign Next-Gen SIEM, especially regarding regional variations. The pricing should not differ based on the country of operation as it can lead to dissatisfaction among customers. A fixed pricing structure would be more favorable for us. I would also suggest enhancing the GUI interface and adding features similar to xFi Exchange from IBM Pure. This would streamline operations and save time for analysts."
"Improvements needed in Logsign SIEM are providing specific security alerts that can be filtered and configured more effectively."
 

Pricing and Cost Advice

"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 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."
"The tool's licensing costs are yearly."
"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."
"The licensing fees for the non-community edition are paid on an annual basis, and there are no costs in addition to this."
"AlienVault OSSIM is free."
"AlienVault OSSIM is an open-source solution."
"Compared to other SIEMs, it has low pricing."
