An open-source solution that provide good detection and more visibility
The solution is not scalable. It impacts so hard. In the initial stages, AlienVault OSSIM can be suitable for small environments. There may be limitations if the customer expresses a desire to expand and add more devices. In such cases, we would need to either explore additional solutions or work within the constraints of the existing setup. We have set up alerts and configured everything in AlienVault OSSIM. It actively monitors for any security incidents. It provides us with regular updates and notifications about any ongoing activities. Only one person is using the solution. It is the perfect solution for small businesses. I rate the solution’s scalability a three out of ten.
Giulio Valeri - PeerSpot reviewer
Efficiently monitoring and detecting suspicious activities
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. For instance, once we were connecting different parts in China, and we had to reserve resources for the blue source of the login of task no v. ConnectWise Fortify successfully mitigated the issue and monitored any suspicious activity in the Microsoft environment. Despite the inconvenience, the Microsoft environment is still active and susceptible to cyber threats. We do a lot of research and utilize ConnectWise Fortify to restart and restore the system. It's essential to have a solution like ConnectWise Fortify to protect against cyber threats.

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 features of AlienVault OSSIM are vulnerability assessment, network intrusion detection system, response to critical events, and awareness of the whole network."
"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."
"Inbuilt IDS, inbuilt integration with threat intelligence platform and with vulnerability assessment modules."
"The most valuable features of AlienVault OSSIM are case management, ease of configuration, and investigation."
"I recommend it due to the experience of the people running it."
"The solution is very stable. Compared to Qradar and Splunk, it's very stable."
"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 open vault component and the checking of vulnerabilities are the most valuable features. The page management helps with this. If you know how your device is vulnerable at least you can do something about 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 correlation engine needs to be improved."
"We need more dashboards and we need more customization for dashboards."
"The main area where the AlienVault product was lacking around the 2018 timeframe was in its ability to scale."
"The user interface needs to be friendlier across the board."
"AlienVault OSSIM failed to provide our company a full insight, while also giving out a lot of false positives."
"AlienVault OSSIM on-premise version is more difficult to implement than the cloud version. Additionally, they should add integration between several different environments at once and improve their online knowledge base."
"AlienVault OSSIM’s configuration and integration could be a little easier."
"When comparing AlienVault OSSIM to other solutions it looks a bit outdated. Additionally, they need to improve their integration."
"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

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