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 paid version of the solution has reporting and better scalability options."
"AlienVault OSSIM's GUI is very user-friendly."
"AlienVault OSSIM is an enterprise solution that sells easily. It is rated highly by organizations."
"The solution is very stable. Compared to Qradar and Splunk, it's very stable."
"Better than other SIEM solutions because almost everything can be integrated."
"The threat policies of the solution are always very advanced and the best in the market. They are very persistent in terms of keeping up with security protocols."
"The solution has a very good open source community, and whenever we have problems, we are always able to resolve it online."
"The dashboard is the solution's most valuable aspect. It brings everything into one central point where I can actually look at it and go, "Okay, I understand what's going on.""
"The integration capabilities of ConnectWise SIEM are off the shelf, making it easy to buy and use; you just unpack it and use it."
"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."
 

Cons

"The main area where the AlienVault product was lacking around the 2018 timeframe was in its ability to scale."
"When comparing AlienVault OSSIM to other solutions it looks a bit outdated. Additionally, they need to improve their integration."
"AlienVault OSSIM should improve the deployment and make it unified like the USM."
"The user interface needs to be friendlier across the board."
"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."
"I suggest more in-built rules based on modern threats and environments to make it a more competitive solution."
"AlienVault OSSIM is costly."
"The documentation could be improved."
"ConnectWise Fortify could work on covering more areas, like phishing messages, which have become more complicated to detect."
"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."
 

Pricing and Cost Advice

"We are using the community version, which can be used for free."
"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."
"The price of AlienVault OSSIM is too high sometimes for us to present to our customers. The price should be lower. We are on a three-year license to use the solution. We had to pay extra for the support."
"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."
"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."
"AlienVault OSSIM is free."
"The solution is expensive."
