Automated protection has reduced our management time and keeps all client environments consistently secure
Reporting in Bitdefender GravityZone Extended Detection and Response (XDR) could be improved. It has some reporting in it, but it's a little cumbersome to work with, so the reporting that is there could be improved. The analytics dashboards of Bitdefender GravityZone Extended Detection and Response (XDR) are quite useful, and they are nice in that we can see an overview very quickly and drill down into specific issues or specific clients. The dashboards are quite good, though it would be nice if we had the same with automated reports. It would be much more useful for us to have that via email or having a report. The only downside that we find is that the product is a little bit slow.

Before Corelight recently started pushing some of the agentic features, querying at times could be a little difficult, depending on your mastery of log scale. However, I think with a lot of the artificial intelligence that they are building in, it is getting a lot easier to query in the platform. I would definitely encourage them to continue down that path where anybody can hop into the platform and start running queries, whether it is a simple instruction like I want this, and an artificial intelligence process can actually build the query and do it. I think that would be super powerful. Cyber skill sets are in high demand, and there is a huge backlog in cyber talent. We cannot fill all the positions we need. The easier we can make these cyber systems for people to pick up and be effective on, I think is really key. Explainability of data is hyper important. In the past few artificial intelligence related updates we have gotten from Corelight, that has been one of the first questions our team has asked every time or that I have asked: show me what the model is doing, show me how it came to this analysis. Within Investigator platform, they are able to walk through and see exactly what data the artificial intelligence pulled from where and why it did what it did as far as making its suggestions. They have definitely built their system with artificial intelligence in mind up front, and having that openness as one of the key features of any of their artificial intelligence and machine learning processes in the platform is important. The issue with black boxes is obviously hallucinations from artificial intelligence and just not being able to trace to ground truth. When we are talking about these cyber incidents and being able to do forensics, you need to be able to pinpoint and tie everything together, and black boxes really obscure that and prevent you from doing so. Corelight has done a really good job of making sure that everything is explainable and everything is mapped when it comes to leveraging any of their artificial intelligence features.

Quotes from Members

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

Pros

"Bitdefender GravityZone Ultra Plus is highly stable."
"We moved from Sophos antivirus to Bitdefender GravityZone Extended Detection and Response (XDR), and ever since then, we've been very happy with the product."
"I find Bitdefender GravityZone Ultra Plus to be a pretty good solution for the mid-level market, specifically for organizations with up to two hundred fifty users. I like that it is an averagely priced solution. It also has a straightforward installation that can be completed within three to five minutes. Its technical support is also good enough."
"The best features in the product, as a reseller, are the integrated SOC; integration with a SOC is one of the advantages."
"The threat detection rates are exceptionally good, better than most of the competition."
"The best thing about Bitdefender is that it has got top-notch features and it is not tied to specific countries like some other antivirus tools."
"We are using Bitdefender GravityZone Ultra Plus for the threat protection and security of our network."
"The product is easy to use."
"Technical support seems to be good."
"It's easy to create additional dashboards specific to supporting specific tasks."
"It's an easy way for us to get visibility in a client's environment."
"It is easy to deploy and easy to handle."
"Corelight Open NDR has had a positive impact on my company, providing visibility as the Suricata engine can scan huge volumes of traffic, including north-south and east-west, revealing signatures and exposures I was not expecting and enabling me to catch them with Suricata alerts."
"Corelight makes much easier the remediation of cyber attacks; instead of facing a chaotic amount of logs, Corelight provides correlated metrics that allow pivoting to find, in seconds, all the data related to an alert, detection, or asset."
"The most valuable feature is the embedded IDS from Suricata."
"Corelight is easy to use."
 

Cons

"The solution seems to be pretty amateur for an EDR solution, and it should be more in sync in terms of features, with solutions such as FireEye and SentinelOne."
"The solution must improve its management features."
"Detection and response is a disadvantage that could be improved."
"Some customers would like additional features that aren't available through the current GravityZone platform. Some feedback has been about the deletion of other software not going smoothly during the installation of Bitdefender, particularly the removal of previous software like Sophos."
"Reporting in Bitdefender GravityZone Extended Detection and Response (XDR) could be improved."
"I would like automatic issue fixing for users without needing to physically open the PC. I'd prefer updates and fixes from the cloud to avoid headaches and save time."
"Adding a feature like Data Loss Prevention would be beneficial."
"The solution’s architecture is complex and difficult to understand. There are multiple machines and VMs."
"They can enhance the interface of the product. They can make it more interactive and also easier to use for feature access."
"Corelight hasn’t added features in a long time."
"It's an expensive solution and the price could be reduced."
"Machine learning could be a good improvement, but it's very costly."
"In the next release, building a graphical user interface would be helpful."
"Before Corelight recently started pushing some of the agentic features, querying at times could be a little difficult, depending on your mastery of log scale."
 

Pricing and Cost Advice

"Bitdefender GravityZone Ultra Plus is pretty average, meaning it's not cheaper, but it's pretty good. It has average pricing."
"We have purchased licenses for the use of Bitdefender GravityZone Ultra Plus. The price of the solution is reasonable but could be better."
"It's a yearly fee and depends on what you are looking for."
