Correlates incidents, allows for quicker identification and helps prioritize investigations
The only challenge is, and that’s where we come into play, it’s a pretty high-tech platform. So, it’s difficult for small and medium-sized organizations to manage it on their own. It’s a very complex system. It requires a lot of expertise. All my guys who work on it have gone through certification from Stellar itself. There are three different certifications that you need to complete. Only then are you certified by Stellar to work on it. It’s a very complex platform. Not everyone can use it. A simple IT engineer or system admin won’t be able to handle it because it’s quite complex. You need to have an understanding of the industry, the subject, and the tool. So, just purchasing this tool or license and then using it on your own would be very difficult to configure and manage on a day-to-day basis. The pricing model is not suitable for small and medium companies, particularly small companies. The minimum pricing model they have is suitable for companies with more than one thousand users. So, if someone has 50 to 100 users, like typical small companies, it’s difficult for them because the cost involved is high. Stellar would charge you for those thousand users, but you do not need all those users. So what are they going to do? I guess Stellar does not want to target small companies directly and maybe relies on resellers and MSPs like us to sell it. So, that is something I would recommend changing. Otherwise, it’s a great tool, but because of the pricing model, small companies are unable to leverage the advantage of this beautiful tool. So, the pricing model should be suitable for small and medium businesses. The product currently has vulnerability monitoring and everything. But if they could also do something about vulnerability management and maybe patch management, that would be nice.

Helps to monitor and detect cyberattacks
The tool's effectiveness depends on how you define your log sources. To build visibility of incoming and outgoing traffic, you need logs from perimeter defense, firewalls, web application firewalls, and endpoint protection. With good traffic visibility, incident response time is really quick. Trellix ESM provides situation awareness. On the dashboard, I can see outbound and inbound communications to known threat hosts, IPS/IDS activity, and threat intelligence of the perimeter defense in the firewall. This information helps preempt attacks.

Quotes from Members

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

Pros

"It can integrate with almost any cybersecurity tool available in the market."
"Stellar Cyber Open XDR offers these functionalities at a more affordable price, making it easier for me to position it with price-sensitive customers."
"The most valuable feature is that if the scanning does find something, it quarantines it. Then you can decide what you are going to do with it."
"Trellix ESM is very user-friendly."
"Scalability is quite easier with Trellix ESM, because all we need to do is add more receivers to it, so it can go to any point."
"The most valuable feature for us is that it comes with many correlations, reports, and dashboards already available. It's also very easy to use."
"The most valuable feature is for the security operation center because it provides visibility of all traffic within the company infrastructure."
"I like the ease of deployment."
"It is easy to use and deploy. It comes with user-friendly manuals."
"It is a good central viewpoint for issues. These can then be investigated in more detail on the subnet server(s)/endpoints."
 

Cons

"Support is an issue because they have a limited number of resources."
"I would rate the stability at about five to six. The platform requires some fine-tuning, especially when integrating data sources and creating connectors."
"Update to user interface from version 9 is cosmetic in some aspects, and after a few clicks you are back on the old interface."
"The product is mature and needs little improvement, but we could enhance the customized dashboarding based on use cases."
"There should be support for multitenancy in the product."
"It cannot integrate with our Next-Generation Firewall and few applications such as Cisco ACI."
"The only drawback is that they don't have any packet capturing or network behavior analysis."
"Product-wise, adding accounts on a single data source by batch would be a really great help."
"I would like to see improvements to the user interface."
"We need to improve Trellix ESM by making sure that most of the logging devices available in the global market should be covered, and if there is any device which is not covered, there should not be any additional charges for writing the custom parsers on that."
 

Pricing and Cost Advice

"It’s a single license platform."
"The pricing is good, and they are competitive compared to providers such as RSA and IBM QRadar."
"The licensing cost is based on EPS."
"McAfee is the right choice for a low-budget solution."
"The cost is all included. The finance department handles the financial part, and we mostly don't get involved in it."
"You should buy the distributed option instead of the all-in-one for environments with more than 1000 end points."
"The cost is dependent on the customer's environment and requirements."
"We pay for our licensing fees on a yearly basis, and there are no costs in addition to the standard licensing fees."
"When compared to IBM Security QRadar and other similar platforms, the pricing of McAfee ESM is reasonable and comparatively less expensive."
