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

"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."

"The user interface could be improved."

"The documentation could be improved."

"The user interface needs to be friendlier across the board."

"It's so hard to configure and explore something new on it."

More AlienVault OSSIM cons

"What I'd like to see as an improvement to ManageEngine EventLog Analyzer is for it to be more AI-driven. Having more automation would also make the solution better."

"There isn't good security integration when it comes to cybersecurity. The correlation of logs isn't so simple."

"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."

"I would like to see more detailed reports."

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

Pricing and Cost Advice

"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 licensing fees for the non-community edition are paid on an annual basis, and there are no costs in addition to this."

"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."

"The tool's licensing costs are yearly."

"The solution is open source, so it's free to use."

"AlienVault OSSIM is free."

"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."

More AlienVault OSSIM pricing and cost advice
