HarshBhardiya - PeerSpot reviewer
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.

Daniel_Martins - PeerSpot reviewer
Experiencing frequent disconnections and support challenges but benefits from quick implementation and integration capabilities
The timeout of the tenant is an area that needs improvement. When investigating and gathering information from the Helix tenant for extended periods, disconnections occur. This results in lost work and the need to restart investigations due to disconnected sessions. It is problematic when progress is lost and investigations must be restarted, resulting in lost information and significant time wastage. The capability to integrate with other TIPs or cybersecurity intelligence sources could be improved to determine whether IOCs are malicious, similar to Mandiant's functionality. The capacity to reduce false positives needs improvement as we receive many alerts from Helix that turn out to be false positives upon investigation. Enhanced capability in this area would make the system more efficient and easier to use. The dashboards could be improved as customers frequently request real-time SOC dashboard displays for Helix.

Quotes from Members

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

Pros

"The dashboard is the solution's most valuable aspect. It brings everything into one central point where I can actually look at it and go, "Okay, I understand what's going on.""
"The solution is free to use."
"The most valuable feature is the logging capability."
"The initial setup is straightforward."
"The most valuable features of AlienVault OSSIM are vulnerability assessment, network intrusion detection system, response to critical events, and awareness of the whole network."
"OSSIM is the only solution that includes the large number of modules that we need: a vulnerability scanner, a network IDS system, a host IDS system."
"The solution has a very good open source community, and whenever we have problems, we are always able to resolve it online."
"Network traffic analysis is highly efficient."
More AlienVault OSSIM pros
"We have started working with various customers, one of whom is particularly concerned about adjacency. We have identified several use cases where automation is possible."
"It is kind of simple and very easily deployable. You can start working with it very fast."
"I advise other customers to choose Trellix Helix, as it improves operations significantly with more efficient responses required for various scenarios they face."
"I like that it's easy. It's got the protection set up, and we can see whatever is required. We write our own rules and the rules that we can input. I think it is good."
"As far as its core functionality goes, it’s spot-on."
"Trellix Helix helps prevent email attacks, like phishing and email spoofing attacks."
"FireEye Helix's best features are its speed and use of an easy-to-understand language to send queries to the raw logs."

More Trellix Helix Connect pros
 

Cons

"When comparing AlienVault OSSIM to other solutions it looks a bit outdated. Additionally, they need to improve their integration."
"AlienVault OSSIM failed to provide our company a full insight, while also giving out a lot of false positives."
"Sometimes technical issues take very long to get resolved."
"I would like the solution to be able to integrate with my firewall, my IDS and my Honeypot solutions so that it can provide real-time reporting as things occur and then have alert sent to me on my phone when suspicious activity is happening."
"The solution is not scalable."
"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 should improve the deployment and make it unified like the USM."
"It's under heavy traffic. If you have heavy traffic, the system is slow."
More AlienVault OSSIM cons
"Integrations could be improved, and the dashboard could be a little better."
"Trellix Helix's configuration and learning could be improved to identify normal traffic from abnormal and to identify trusted domains."
"The graphical user interface could be improved. It's not easy to handle and it's not easy for a customer or end-user to learn how to manage the solution."
"We often rely on Martins to create logs and provide professional threat services rather than basic support."
"We have certain challenges with integrating the SOAR platform with multiple vendors."
"Sometimes the rules are disabled by FireEye, and we basically get it after the patch. I think there needs to be a better way of creating the application rules. I would like to see better pricing for our licensing."
"There is room for improvement in the integration capabilities of third-party tools."
"FireEye Helix would be improved with the option of an on-prem version, which they don't currently offer."
More Trellix Helix Connect cons
 

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."
"OSSIM is free."
"The tool's licensing costs are yearly."
"We are using the community version, which can be used for 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."
"AlienVault OSSIM is free."
"The solution is open source, so it's free to use."
More AlienVault OSSIM pricing and cost advice
"It could be cheaper, but that applies to every product."
"I rate Trellix Helix a five out of ten for pricing."
"The price could be better. But I think it's rightly placed when we buy everything in one shot, and we get some discount for that. That's how we basically plan our deployment, and it's holistic. We pay for the license yearly."
"FireEye Helix is a little expensive."
