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.

Automated alerting and reporting excel while cost and feature limitations remain
I find automation to be one of the best and most valuable features of the product. Machine learning is incorporated into the solution, though AI is a broader term that I wouldn't apply here. I haven't personally explored AI yet, but I will investigate it. Machine learning functions more as automation in my experience, as there's no training involved yet. I want to conduct R&D on another project with Wazuh to determine how to capture usage, for example, tracking user logins and time spent. This is where I need to implement machine learning. Additionally, the extraction of GeoIP adds complexity. The solution is effectively reducing incident response times in operations.

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 feature is the logging capability."
"The most valuable features of AlienVault OSSIM are vulnerability assessment, network intrusion detection system, response to critical events, and awareness of the whole network."
"This solution is very stable; it runs on a Linux box, you only interface with it through the GUI, it works behind the scenes, and it has never crashed in the time that I have used it."
"I have worked with LogRhythm in the past, since 2015, and I find that AlienVault is a better product."
"With AlienVault you get everything in one box."
"If you compare with other companies, like LogRhythm, etc., the top 8 or 10 CMs, I think AlienVault has the best price-performance ratio."
"The paid version of the solution has reporting and better scalability options."
"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."
"One valuable feature of ConnectWise Fortify is the ability to add other teams and receive notifications when customers make changes or remove multi-factor authentication in Microsoft or SAP environments."
"We have found the solution has great functionality and it is easy to use."
"We have found the solution has great functionality and it is easy to use."
"The integration capabilities of ConnectWise SIEM are off the shelf, making it easy to buy and use; you just unpack it and use it."
 

Cons

"I don't like to work on OSSIM because it is unpredictable."
"They can add more compliance templates."
"I would advise others to not implement it for any enterprise-level organization."
"There needs to be more support or some kind of training program so users can self-learn the system more effectively."
"There needs to be more support or some kind of training program so users can self-learn the system more effectively."
"The user interface needs to be friendlier across the board."
"The initial setup was not so easy, partly because the documentation was not up to date."
"AlienVault OSSIM failed to provide our company a full insight, while also giving out a lot of false positives."
"The manage portion of the solution is complicated and should be simplified by having different versions to meet the needs of different size companies."
"ConnectWise SIEM is primarily focused on notifications and is limited in that aspect, while Wazuh can automate the elimination process."
"The manage portion of the solution is complicated and should be simplified by having different versions to meet the needs of different size companies."
"ConnectWise Fortify could work on covering more areas, like phishing messages, which have become more complicated to detect."
 

Pricing and Cost Advice

"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."
"AlienVault OSSIM is expensive compared to its competitors."
"OSSIM is free."
"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."
"The tool's licensing costs are yearly."
"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."
"The solution is open source, so it's free to use."
"The solution is expensive."
