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

"You can customize the dashboards as well as the reporting."
"I recommend it due to the experience of the people running it."
"There are a lot of people you will find using OSSIM since they are also offering OTX as a service"
"A very good feature of AlienVault OSSIM is that it has many domains that can be integrated from different solutions."
"Asset discovery is good."
"The most valuable feature is the logging capability."
"The solution is very stable, and compared to QRadar and Splunk, it's very stable."
"The most valuable features of AlienVault OSSIM are vulnerability assessment, network intrusion detection system, response to critical events, and awareness of the whole network."
"It is kind of simple and very easily deployable, and you can start working with it very fast."
"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."
"Trellix Helix helps prevent email attacks, like phishing and email spoofing attacks."
"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."
"I advise other customers to choose Trellix Helix, as it improves operations significantly with more efficient responses required for various scenarios they face."
"The pre-built rules and analytics save us a lot of time and have positively impacted my team's workflow because whenever we migrate to a new tool, we basically have to sit for months to form the rules and alerts."
"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."
"The best feature of Trellix Helix Connect is its quick implementation."
 

Cons

"There needs to be more focus on the NOC and IIS in terms of developing applications for behavior detection."
"The log collection is okay, but tracing the logs or tracing the events is a bit difficult."
"I suggest more in-built rules based on modern threats and environments to make it a more competitive solution."
"The main area where the AlienVault product was lacking around the 2018 timeframe was in its ability to scale."
"The incidence reporting could be better."
"They can add more compliance templates."
"The solution needs more integration with cyber intelligence systems. Our customers want to use a single tool for managing cybersecurity."
"The solution is not scalable."
"We often rely on Martins to create logs and provide professional threat services rather than basic support."
"It should have more cloud connectors. It could also be cheaper."
"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."
"Trellix needs to address the price for the product to be more appealing to customers."
"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."
"I think the usability of hyperautomation is something to improve in the solution because it is expensive regarding the needed improvements."
"The most problematic part was the integration part because in their catalog, they have so many third-party vendors, but some of them were not fully supported, so we requested some development and feature requests."
"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."
 

Pricing and Cost Advice

"AlienVault OSSIM is free."
"The licensing fees for the non-community edition are paid on an annual basis, and there are no costs in addition to this."
"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."
"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."
"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."
"When comparing AlienVault OSSIM to Microsoft Sentinel, AlienVault OSSIM incurs additional costs due to its licensing price structure. If you are using AlienVault for security purposes at a certain level it can have a higher price point than the current pricing of Microsoft Sentinel."
"The solution is open source, so it's free to use."
"It could be cheaper, but that applies to every product."
"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."
"FireEye Helix is a little expensive."
