Good quality ransomware antivirus that provides automatic patch management
Bitdefender GravityZone XDR is a good quality ransomware antivirus product. We like it because it's an industry-quality antivirus as opposed to some of the better-known ones like Symantec or Norton. Bitdefender has a better reputation for being up-to-date and picking up more threats. Patch management is important to keeping companies secure. The solution has an automatic patch management capability. Customers never find their software or operating systems vulnerable because Bitdefender would have automatically patched them. Bitdefender sells XDR and EDR products, but we tend to stop at the EDR level. BitDefender has lots of modules if people want to pay for them. We primarily push encryption patching and antivirus and integrate that into the security operations center.

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.

Quotes from Members

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

Pros

"The HyperDetect feature in GravityZone XDR is effective."
"I appreciate the overall utilization of AI to enhance security posture."
"The solution has an automatic patch management capability."
"Scalability is pretty easy. It's easy to increase the capacity. You can just add on licenses to the existing license, and the duration of the license can be adjusted. For example, you've already bought a license for a year, and you want to add some more users. We can just add on licenses for the remaining period so that the entire organization can have the same expiry date. That makes renewal easier."
"I find that the auto-response capability is most valuable."
"It provides an in-depth analysis and gives recommendations, along with a historical search capability."
"I would rate GravityZone XDR more than nine out of ten."
"Stellar Cyber Open XDR offers these functionalities at a more affordable price, making it easier for me to position it with price-sensitive customers."
"It can integrate with almost any cybersecurity tool available in the market."
 

Cons

"The resource consumption is high for Bitdefender GravityZone XDR, nearly using one gigabyte of RAM, especially on Windows 10 and 11."
"The product could be improved by offering a single panel for the management of all Bitdefender products."
"It's not very mature, and additional costs are involved."
"The solution’s pricing could be improved."
"The product could be improved by offering a single panel for the management of all Bitdefender products. Additionally, there might be a need to simplify the interface in the future."
"The resource consumption is high for Bitdefender GravityZone XDR, nearly using one gigabyte of RAM, especially on Windows 10 and 11."
"Another area of improvement is CPU utilization. CPU utilization could be improved."
"I would rate the stability at about five to six. The platform requires some fine-tuning, especially when integrating data sources and creating connectors."
"Support is an issue because they have a limited number of resources."
 

Pricing and Cost Advice

"On a scale from one to ten, where one is cheap and ten is expensive, I rate the solution's pricing a six out of ten."
"It's not the price of the software itself that makes it expensive. It's because you have to buy a VM; you have to buy additional hardware. All those things make it slightly costlier."
"It’s a single license platform."
