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

"The initial setup was straightforward. I didn't have any problems."
"You pay monthly for the solution. I think it's one of the best products. If you compare with other companies, like LogRhythm, etc., the top 8 or 10 CMs, I think Alien Vault has the best price-performance ratio."
"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."
"The most valuable features of AlienVault OSSIM are case management, ease of configuration, and investigation."
"Technical support is excellent; they are very helpful and responsive."
"The most valuable features of AlienVault OSSIM are vulnerability assessment, network intrusion detection system, response to critical events, and awareness of the whole network."
"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 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."
"It has full automation and automated SIEM responses."
"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."
 

Cons

"The price of this solution is very high and it could be cheaper."
"AlienVault OSSIM gives unwanted notifications."
"The correlation engine needs to be improved."
"The biggest thing I always complain about is that the user intake is a very old version."
"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 log collection is okay, but tracing the logs or tracing the events is a bit difficult."
"There needs to be more focus on the NOC and IIS in terms of developing applications for behavior detection."
"They can add more compliance templates."
"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."
"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."
 

Pricing and Cost Advice

"OSSIM is free."
"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 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 an open-source solution."
"The tool's licensing costs are yearly."
"The solution is open source, so it's free to use."
"We are using the community version, which can be used for free."
"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."
"Compared to other SIEMs, it has low pricing."
