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 initial setup was straightforward. I didn't have any problems."
"I have deployed it widely because I find that it gives value for money."
"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."
"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."
"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."
"The open vault component and the checking of vulnerabilities are the most valuable features, and the page management helps with this, because if you know how your device is vulnerable at least you can do something about it."
"The product is easy to use."
"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."
"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."
"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

"The price of this solution is very high and it could be cheaper."
"AlienVault OSSIM gives unwanted notifications."
"AlienVault OSSIM failed to provide our company a full insight, while also giving out a lot of false positives."
"Sometimes it takes very long for your issue to get resolved."
"It's so hard to configure and explore something new on it. It is not easy to find the steps we need to follow in order to use the solution effectively."
"Lacking in depth of reporting."
"ArcSight works better than AlienVault right now."
"The biggest thing I always complain about is that the user intake is a very old version."
"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

"The solution is open source, so it's free to use."
"AlienVault OSSIM is an open-source solution."
"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."
"OSSIM is free."
"We are using the community version, which can be used for free."
"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."
"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 expensive compared to its competitors."
"The solution is expensive."
