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.

Centralized threat triage has improved endpoint control but still needs better cloud insights
Trellix Helix Connect can definitely be improved, especially regarding cloud and SaaS telemetry gaps. It could enhance its native cloud and SaaS telemetry integration. Additionally, sometimes when we open the details of a file, it lacks meta fields altogether, and we must manually ask the user for the meta fields, such as when the file was created, last opened, last updated, and its hash value. Helix does not perform as expected in this regard. There are also many false positives flagged that should not be, and there is no on-premises option for FireEye Helix. Lastly, the GUI and dashboard feel very old-school and legacy, needing improvement, as all competitors have far superior GUIs and UI/UX interfaces. I would add that we have experienced specific problems with session timeouts where we randomly log out from the system after some time and face issues in logging back in. This required us to contact customer service frequently, which is also not very reliable or prompt.

Quotes from Members

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

Pros

"The threat alerts it gives me from time to time on harmful code within the network, or if they are generating any network traffic, are very useful."
"The solution is very stable, and compared to QRadar and Splunk, it's very stable."
"Asset discovery is good."
"Technical support is excellent; they are very helpful and responsive."
"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," and the solution works well and allows me to have visibility into anomalous events."
"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."
"I recommend it due to the experience of the people running it."
"The solution has a very good open source community, and whenever we have problems, we are always able to resolve it online."
"The features that I find most valuable in Trellix Helix Connect are the incident response capabilities, which include EDR and XDR, along with the SoC capabilities added in the new advanced Trellix AI intelligence."
"Trellix Helix helps prevent email attacks, like phishing and email spoofing attacks."
"We are able to block some advanced malware and other things."
"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."
"FireEye Helix's best features are its speed and use of an easy-to-understand language to send queries to the raw logs."
"As far as its core functionality goes, it’s spot-on."
"Trellix Helix Connect has positively impacted our organization by improving our security, as we now have fewer attacks and more peace of mind when working, improved efficiency within the office staff, and increased security for our applications, and we were able to integrate internal applications already developed through API and other Trellix tools that we already used."
"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."
 

Cons

"It's under heavy traffic. If you have heavy traffic, the system is slow."
"The solution is not scalable."
"The initial setup was a bit complex. You've got to do a lot of reading. It's not an intuitive implementation."
"There needs to be more support or some kind of training program so users can self-learn the system more effectively."
"I suggest more in-built rules based on modern threats and environments to make it a more competitive solution."
"Sometimes it takes very long for your issue to get resolved."
"When comparing AlienVault OSSIM to other solutions it looks a bit outdated. Additionally, they need to improve their integration."
"The biggest thing I always complain about is that the user intake is a very old version."
"It should have more cloud connectors. It could also be cheaper."
"The support would rate a three out of ten. It can take one to four weeks to connect with someone who truly understands Helix and can provide solutions."
"We have certain challenges with integrating the SOAR platform with multiple vendors."
"We often rely on Martins to create logs and provide professional threat services rather than basic support."
"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."
"The weak point of Trellix Helix Connect is the data storage capacity; more storage must be purchased as the data grows, which is a disadvantage because the cost increases when more space is needed on the cloud."
"Regarding areas for improvement with Trellix Helix, I believe that if the integration with AWS and GCP environments could be improved, that would be beneficial."
"Trellix Helix's configuration and learning could be improved to identify normal traffic from abnormal and to identify trusted domains."
 

Pricing and Cost Advice

"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."
"AlienVault OSSIM is an open-source solution."
"OSSIM is free."
"AlienVault OSSIM is expensive compared to its competitors."
"OSSIM is open source, and USM is the paid license. So, if you want, you can switch to USM. There you will have to buy a license, and they have a support team that helps you out on issues you face."
"AlienVault OSSIM is free."
"The solution is open source, so it's free to use."
"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."
"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."
"It could be cheaper, but that applies to every product."
"FireEye Helix is a little expensive."
