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.

Efficient log management enhances activity monitoring despite VPN user issue

Last month, we faced an issue with a Hawaiian VPN user activity. It's like a Fortinet device configured for VPN users. When a VPN user logs in, it doesn't really capture the time before this. If you're testing with existing or new device integration, then the product will be good in the market.

Cons

"The main area where the AlienVault product was lacking around the 2018 timeframe was in its ability to scale."

"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."

"AlienVault OSSIM should improve the deployment and make it unified like the USM."

"AlienVault OSSIM could improve by having better integration with some of the newer tools."

"The correlation engine needs to be improved."

"The scalability is limited."

"The customization of reports could be a lot easier. It is not difficult but it could be made easier."

"The first tier of customer service and support is not great."

"Support could improve to make the solution better."

"Last month, we faced an issue with a Hawaiian VPN user activity."

"The solution is stable. However, there are limits. For example, we can do 2,500 Syslog events per second, but if we want to do more we have to install the distributor structure, and then we can expand how many events we can do. They could improve the stability."
