Independent Contractor at a comms service provider with 5,001-10,000 employees

Enables cost-effective security management for small businesses

Scaling for USM is always challenging for any product unless it is purpose-built or overbuilt at the front end. They will use Palo Alto and its competitors, and LevelBlue will manage that implementation. The main area where the AlienVault product was lacking around the 2018 timeframe was in its ability to scale. By pushing it to a cloud-based system, they've largely alleviated scale issues. It's native in Amazon but will also run in Azure. They have worked with cloud service providers to offer enough throughput at a cost reasonable for a corporation. Scaling was their biggest problem, and they've largely conquered those issues.

Presales Lead at a outsourcing company with 11-50 employees

Reduces detection and response times through automation and alert correlation

The best features that Trellix Helix Connect offers are SOAR, automation, hyperautomation, and the correlation of alerts and threat intelligence, for example, when the alerts cross through MITRE ATT&CK, which stand out most to me. Out of those features, automation, alert correlation, and threat intelligence have made my work easier and more effective as we integrate many cybersecurity solutions into the XDR and set up the use cases to reduce MTTD and MTTR from days to minutes. I would add that the level of integration with other brands is something that surprises me about the features of Trellix Helix Connect. Trellix Helix Connect has positively impacted my organization as it is the most important tool to provide MDR service to our clients, which has resulted in specific outcomes and improvements.

Quotes from Members

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

Pros

"It is a perfectly nice and free tool for compliance testing, assessment, and some basic vulnerability."

"The solution is free to use."

"The open vault component and the checking of vulnerabilities are the most valuable features, and the page management helps with this, because if you know how your device is vulnerable at least you can do something about it."

"The most valuable features of this solution are the data correlation and vulnerability assessment."

"The solution is free to use."

"The tool's security detection is good. It helps us with login tracking and generating reports. We aim to identify potential issues, such as brute-force attacks on user accounts or server-level anomalies. For instance, if I receive a report indicating a server is at an abnormal level, I investigate and address the issue."

"The solution is very stable, and compared to QRadar and Splunk, it's very stable."

"Technical support is excellent; they are very helpful and responsive."

More AlienVault OSSIM pros

"The solution is very high-quality and offers a very small number of false positives, so we don't have to get distracted by checking up on false data and making sure nothing is wrong."

"It is kind of simple and very easily deployable. You can start working with it very fast."

"With FireEye Helix, if a customer already uses any of the FireEye endpoint solutions, the response part is very fast and the investigation is also very fast."

"I like that it's easy, it's got the protection set up, and we can see whatever is required."

"Trellix Helix helps prevent email attacks, like phishing and email spoofing attacks."

"The integration is very useful and very easy. You can have an API connection with any cloud and I'll be able to do both ways of communication with the help of APA."

"We are able to block some advanced malware and other things."

"The most valuable features include predefined use cases and threatening states."

More Trellix Helix Connect pros

Cons

"Lacking in depth of reporting."

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

"AlienVault OSSIM’s configuration and integration could be a little easier."

"The correlation engine needs to be improved."

"ArcSight works better than AlienVault right now."

"The correlation engine needs to be improved."

"It's under heavy traffic. If you have heavy traffic, the system is slow."

"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."

More AlienVault OSSIM cons

"I think the usability of hyperautomation is something to improve in the solution because it is expensive regarding the needed improvements."

"Integrations could be improved, and the dashboard could be a little better."

"While we have top customer support and this solution is highly beneficial, there is room for improvement due to the fusion of McAfee and FireEye, which has caused some lapses in support."

"It should have more cloud connectors. It could also be cheaper."

"There is room for improvement in the integration capabilities of third-party tools."

"Integrations could be improved, and the dashboard could be a little better."

"Sometimes the rules are disabled by FireEye, and we basically get it after the patch."

"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

"AlienVault OSSIM is an open-source solution."

"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."

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

"We are using the community version, which can be used for free."

"AlienVault OSSIM is expensive compared to its competitors."

"OSSIM is free."

More AlienVault OSSIM pricing and cost advice

"It could be cheaper, but that applies to every product."

"FireEye Helix is a little expensive."

"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."

"I rate Trellix Helix a five out of ten for pricing."
