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

"AlienVault OSSIM's GUI is very user-friendly."
"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."
"The most valuable features of this solution are the data correlation and vulnerability assessment."
"With AlienVault you get everything in one box."
"Most of the SOC or SIEM enterprise class products are very expensive, whereas with OSSIM you can start out with a smaller setup and then expand as you wish."
"The solution has a very good open source community, and whenever we have problems, we are always able to resolve it online."
"The most valuable features of AlienVault OSSIM are vulnerability assessment, network intrusion detection system, response to critical events, and awareness of the whole network."
"I have worked with LogRhythm in the past, since 2015, and I find that AlienVault is a better product."
"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."
"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."
"As far as its core functionality goes, it’s spot-on."
"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."
"The product offers very strong automation. Our cyber security analysts don't have to correlate the information to detect problems. They only need to analyze problems that have been identified by the platform."
"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 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."
 

Cons

"The price of this solution is very high and it could be cheaper."
"AlienVault OSSIM should improve the deployment and make it unified like the USM."
"It's so hard to configure and explore something new on it. It is not easy to find the steps we need to follow in order to use the solution effectively."
"The log collection is okay, but tracing the logs or tracing the events is a bit difficult."
"The correlation engine needs to be improved."
"They can add more compliance templates."
"It's under heavy traffic. If you have heavy traffic, the system is slow."
"Sometimes it takes very long for your issue to get resolved."
"It should have more cloud connectors. It could also be cheaper."
"I think the usability of hyperautomation is something to improve in the solution because it is expensive regarding the needed improvements."
"There is little training available for technology teams to master the key features of Trellix Helix Connect, and that could be improved."
"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."
"FireEye Helix would be improved with the option of an on-prem version, which they don't currently offer."
"There are some issues such as high CPU utilization that we have experienced in the past whenever we were using Trellix Endpoint Security in the cloud system, which prevented anyone from working properly."
"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 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."
 

Pricing and Cost Advice

"We are using the community version, which can be used for free."
"AlienVault OSSIM is free."
"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."
"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 tool's licensing costs are yearly."
"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."
"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."
"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."
"FireEye Helix is a little expensive."
"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."
