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.

Cyber Security Software Engineer at a tech services company with 11-50 employees
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 is straightforward."
"I have worked with LogRhythm in the past, since 2015, and I find that AlienVault is a better product."
"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 most valuable features of AlienVault OSSIM are case management, ease of configuration, and investigation."
"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 threat alerts it gives me from time to time on harmful code within the network, or if they are generating any network traffic, are very useful."
"The paid version of the solution has reporting and better scalability options."
"The most valuable features of this solution are the data correlation and vulnerability assessment."
"We have found the solution has great functionality and it is easy to use."
"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."
"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 incidence reporting could be better."
"The solution needs more integration with cyber intelligence systems. Our customers want to use a single tool for managing cybersecurity."
"Lacking in depth of reporting."
"AlienVault OSSIM is costly."
"The initial setup was a bit complex. You've got to do a lot of reading. It's not an intuitive implementation."
"The documentation could be improved."
"There needs to be more focus on the NOC and IIS in terms of developing applications for behavior detection."
"The solution is not scalable."
"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."
"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 tool's licensing costs are yearly."
"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."
"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."
"AlienVault OSSIM is an open-source solution."
"OSSIM is free."
"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."
"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 solution is expensive."
