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

"AlienVault OSSIM's GUI is very user-friendly."
"The paid version of the solution has reporting and better scalability options."
"Network traffic analysis is highly efficient."
"You pay monthly for the solution. I think it's one of the best products. If you compare with other companies, like LogRhythm, etc., the top 8 or 10 CMs, I think Alien Vault has the best price-performance ratio."
"I recommend it due to the experience of the people running it."
"The initial setup was straightforward. I didn't have any problems."
"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 most valuable features of this solution are the data correlation and vulnerability assessment."
More AlienVault OSSIM pros
"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 helps prevent email attacks, like phishing and email spoofing attacks."
"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."
"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."
"The most valuable features include predefined use cases and threatening states."
"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 my organization as it is the most important tool to provide MDR service to our clients, which has resulted in specific outcomes and improvements."

Cons

"I suggest more in-built rules based on modern threats and environments to make it a more competitive solution."
"There needs to be more support or some kind of training program so users can self-learn the system more effectively."
"AlienVault OSSIM’s configuration and integration could be a little easier."
"Sometimes technical issues take very long to get resolved."
"The incidence reporting could be better."
"The user interface needs to be friendlier across the board."
"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."
"The user interface could be improved."
More AlienVault OSSIM cons
"Trellix needs to address the price for the product to be more appealing to customers."
"There is room for improvement in the integration capabilities of third-party tools."
"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."
"Integrations could be improved, and the dashboard could be a little better."
"FireEye Helix would be improved with the option of an on-prem version, which they don't currently offer."
"Trellix Helix's configuration and learning could be improved to identify normal traffic from abnormal and to identify trusted domains."
"We have certain challenges with integrating the SOAR platform with multiple vendors."
"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."
More Trellix Helix Connect cons
 

Pricing and Cost Advice

"AlienVault OSSIM is expensive compared to its competitors."
"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 OSSIM is free."
"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."
"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."
"The solution is open source, so it's free to use."
"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."
More AlienVault OSSIM pricing and cost advice
"I rate Trellix Helix a five out of ten for pricing."
"FireEye Helix is a little expensive."
"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."
