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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Network traffic analysis is highly efficient."
"AlienVault OSSIM is an enterprise solution that sells easily. It is rated highly by organizations."
"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."
"There are a lot of people you will find using OSSIM since they are also offering OTX as a service"
"The initial setup was straightforward. I didn't have any problems."
"The most valuable feature is the logging capability."
"With AlienVault you get everything in one box."
"The solution is free to use."
"The tool's most valuable feature is the encryption feature. From a security perspective, the solution hasn't significantly strengthened our security posture. However, it has greatly improved performance by streamlining encryption processes and avoiding encryption at multiple layers. This has also simplified troubleshooting, as we can whitelist certain processes."
"The most valuable feature for improving network visibility with Gigamon is the packet filtering capability."
"The most valuable feature is NetFlow."
"The Pipeline's Comprehensive Insights into data flows have helped improve operational efficiency and security."
"It has high stability."
"It is a good product. It provides network visibility, which is important. Gigamon can bring some optimizations to my network. It is helpful for security inspection, and it makes my firewall work fast because my firewall doesn't have to do the inspection of the SSL connections, for example."
"The solution is straightforward to set up."
"It offers straightforward integration."
 

Cons

"AlienVault OSSIM could improve by having better integration with some of the newer tools."
"There needs to be more support or some kind of training program so users can self-learn the system more effectively."
"The documentation could be improved."
"The price of this solution is very high and it could be cheaper."
"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."
"It's so hard to configure and explore something new on it."
"AlienVault OSSIM failed to provide our company a full insight, while also giving out a lot of false positives."
"Lacking in depth of reporting."
"The graphical user interface could be improved."
"It only inspects a specific kind of traffic. There should be different kinds of use cases."
"The security should be improved."
"In terms of improvement, while the initial setup is not overly complicated, we did encounter a few issues."
"The Gigamon Deep Observability Pipeline should have a feature showing the traffic flow within its platform. Currently, customers have to use separate tools for monitoring, which is inconvenient. If it had its visibility feature, it would make monitoring easier and more complete without needing extra tools."
"They should increase the solution's cluster capacity."
"Gigamon Deep Observability Pipeline needs to improve its performance. I face issues with performance because we use SPAN, and the SPAN traffic is not good."
"Its filtering feature needs improvement."
 

Pricing and Cost Advice

"We are using the community version, which can be used for free."
"AlienVault OSSIM is expensive compared to its competitors."
"The licensing fees for the non-community edition are paid on an annual basis, and there are no costs in addition to this."
"The tool's licensing costs are yearly."
"AlienVault OSSIM is an open-source solution."
"The solution is open source, so it's free to use."
"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."
"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."
"I would rate the solution as expensive, around an eight or nine out of ten. There are other competitive solutions available."
"The solution is highly-priced."
"The solution's price is reasonable."
