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.

Works well for threat detection and security

Improvements needed in Logsign SIEM are providing specific security alerts that can be filtered and configured more effectively. There should be a focus on delivering alerts tailored to specific needs rather than overwhelming users with numerous alerts. Additionally, incorporating more mature data about threats is necessary for better threat detection.

Quotes from Members

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

Pros

"The initial setup is straightforward."

"The solution has a very good open source community, and whenever we have problems, we are always able to resolve it online."

"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 threat policies of the solution are always very advanced and the best in the market, and they are very persistent in terms of keeping up with security protocols."

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

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

"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."

"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."

More AlienVault OSSIM pros

"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."

"The most valuable features of Logsign SIEM are its cloud capabilities, alerting functionality, integration with Elastic Search, and configuration options."

"It has full automation and automated SIEM responses."

Cons

"Sometimes it takes very long for your issue to get resolved."

"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."

"When comparing AlienVault OSSIM to other solutions it looks a bit outdated. Additionally, they need to improve their integration."

"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."

"The log collection is okay, but tracing the logs or tracing the events is a bit difficult."

"I don't like to work on OSSIM because it is unpredictable."

"The main area where the AlienVault product was lacking around the 2018 timeframe was in its ability to scale."

More AlienVault OSSIM cons

"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."

"AI and machine learning need to be developed. If they develop those features, I think everything will be fine."

"Improvements needed in Logsign SIEM are providing specific security alerts that can be filtered and configured more effectively."

Pricing and Cost Advice

"OSSIM is free."

"The licensing fees for the non-community edition are paid on an annual basis, and there are no costs in addition to this."

"The tool's licensing costs are yearly."

"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."

"The solution is open source, so it's free to use."

"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 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."

More AlienVault OSSIM pricing and cost advice

"Compared to other SIEMs, it has low pricing."
