Gained full visibility and streamlined threat detection through behavior-based insights and AI integration

Initially, we got to have a lot of false positives when we onboarded, but nowadays it's quite smooth. We have fine-tuned our security policies and allowed different levels of policies to get rid of those false positives. Currently, we are getting a fairly good amount of incidents that are not false positives or benign, but actionable items. The process is streamlined. In the initial days, the operations used to get involved in a lot of benign and other activities, but now the process is streamlined. We are leveraging the auto-detection and remediation plans. The operations teams are now more involved in other business roles as well, not just looking into the logs and fetching out what's happening there. They have fixed a lot of things. Initially, they didn't have IAC code drift detection, cloud posture management, or security posture management, but they have those now. They purchased different vendors and did a merger with that. They have now Prisma Cloud that gets integrated and now they are working with Cortex Cloud. Everything that was negative has now been addressed, and the product altogether looks to be in a very better and mature shape now. Currently, it's more or less detecting the workloads with AI-based best practices. Since most organizations are consuming AI agents and other things, we are looking forward to seeing what other feature enhancements Palo Alto can support in that.

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.

AI-driven SOC triage has transformed threat monitoring and keeps our security work focused

The best features UnderDefense offers include mostly triage in-context signals read together across my stack, where one finding replaces many separate checks. A good thing too is its false positive suppression, as I do not get false notifications. Normal activity such as traffic spikes during customer events is recognized and documented, and only the unusual cases reach me. It has full-time support 24/7 with proactive reports, and monitoring runs around the clock. Reports and alerts come to me without even noticing or asking, so it is very useful. My team sees what happened without having to chase it. I find the proactive reporting and 24/7 support to have definitely made a real difference. Proactive reports mean I hear about what happened without having to ask, so I know the state of things at the start of the day, and 24/7 support matters most for traffic spikes and other events outside busy working hours, as I get an answer when I need one without keeping someone on call just in case, saving me a lot of time. Together, they let my team stay on infrastructure work and step in only when a decision is needed. Regarding UnderDefense's AI capabilities, I think the governance and security is the best there is, as the decisions that matter stay with my team and each finding is documented, allowing me to review afterwards how a conclusion was reached. That control and traceability is what I need from AI in a security role. The accuracy and reliability of UnderDefense's AI output is accurate and steady, as findings have matched what I saw when I checked them, and the pattern assessments are consistent, especially during large traffic events or spikes, which is when I depend on them most. When a case needs judgment, the reasoning is there so I can confirm it myself.

Quotes from Members

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

Pros

"If any application performs suspicious activities, such as changing registries or modifying other applications, Cortex XDR detects and blocks the entire application."

"Based on my experience with Cortex XDR by Palo Alto Networks, I highly recommend it due to its quick response to zero-day attacks and low utilization from end-user devices."

"I have found the solution to be very easy in respect of the integration and configurable."

"The interface is easy to use and it is more up to date than our previous solution."

"Cortex XDR by Palo Alto Networks is easy to use and does not consume a lot of hardware resources."

"The user interface of the solution is sophisticated and straightforward."

"The ability to kind of stitch everything together and see the actual complete picture is very useful. I guess you'd call it a playbook. Some people call it the forensics analysis of what was happening on particular endpoints when they detected some malicious behavior, and what transpired before that to cause that. It is also very user friendly. The way they have done everything and integrated all the solutions that they've purchased over the years to make it a very seamless, effective product is very good. One thing about Palo Alto is that they take the products or services that they purchase and make them seamless for the end user as compared to some companies that purchase other companies and then just kind of have their products off to the side or keep different interfaces. Palo Alto doesn't do that."

"It is a simple platform to use."

More Cortex XDR by Palo Alto Networks pros

"The threat detection rates are exceptionally good, better than most of the competition."

"The best features in the product, as a reseller, are the integrated SOC; integration with a SOC is one of the advantages."

"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 quarantine computer functionality is very good for me."

"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."

"Bitdefender GravityZone Ultra Plus is highly stable."

"The product is easy to use."

"The solution has best-in-breed technology and scores very highly on efficacy rates."

More Bitdefender GravityZone Extended Detection and Response (XDR) pros

"UnderDefense groups it into one alert with the caller, the endpoint, and the usual pattern, which allows us to contact the customer the same day with facts in hand."

"Routine signals are handled and documented, and only cases that need a human decision reach my team, allowing engineers to spend their time on infrastructure hardening instead of log digging."

"UnderDefense Gen AI SOC flags behavior that breaks from an account's own baseline, lays out which signals triggered the alert and why it reads as different from normal activity, and helps our team decide within the same day whether we are seeing a legitimate big campaign push or a compromised login."

"Every morning we look at a short list of cases that matter instead of a long list of raw alerts, and each case comes with the full picture, so we can decide in a few minutes whether it needs action."

"The linking, the filtering, and the readable reasoning each help on their own, but together, they allow a small security team to handle the volume our platform produces without losing sight of the cases that matter."

Cons

"Cortex XDR could improve its sales support team, including better commission structures and referral programs."

"Being able to filter the events to see those that are related to the actual alert would save time spent by the engineer."

"Cortex XDR by Palo Alto Networks is a very good product, but financially, it is very expensive, so the company should look into that area."

"In the next release, I would like to see more UI improvements. Their UI is a bit basic. When we are speaking about Palo Alto Networks they are the big company, so they can improve the UI a little bit. The UI, the reports, the log system can all be improved."

"The GUI could be improved."

"Cortex XDR by Palo Alto Networks is a strong tool, but it is true that digesting information sometimes makes the tool go a little bit slower."

"It would be good to have a better way to search for a file within the UI."

"The solution lags to the real-time scenarios here and there."

More Cortex XDR by Palo Alto Networks cons

"The solution must improve its management features."

"Adding a feature like Data Loss Prevention would be beneficial."

"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."

"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."

"Reporting in Bitdefender GravityZone Extended Detection and Response (XDR) could be improved."

"Detection and response is a disadvantage that could be improved."

"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."

"UnderDefense could improve in onboarding, which takes some dedicated time because the baseline for our high volume upload events needs to be set up first."

Pricing and Cost Advice

"Traps pays for itself within the first 16 months of a three-year subscription. This is attributed to OPEX savings, as security teams spent less time trying to identify and isolate malware for analysis as a result of a reduction in malware incidents, false positives, and breach avoidance."

"The pricing is a little high. It is per user per year."

"The price of the solution could be reduced. I have customers that have voiced that the solution is good for the value but if I want to sell more of the solution the price reduction would help."

"The pricing is okay, although direct support can be expensive."

"It's the most expensive solution, but features-wise, it's quite strong. It's very good for protection, so the results are very good in the case of protection. I would rate it a two out of ten in terms of pricing."

"It's way too expensive, but security is expensive. You pay for your licensing, and then you pay for someone to monitor the stuff."

"It has a higher cost than other solutions, like CrowdStrike or Microsoft’s EDR tools, but it reduces the cost of our operations because it’s a new generation antivirus tool."

"It has reasonable pricing for the use cases it provides to the company."

More Cortex XDR by Palo Alto Networks pricing and cost advice

"We have purchased licenses for the use of Bitdefender GravityZone Ultra Plus. The price of the solution is reasonable but could be better."

"Bitdefender GravityZone Ultra Plus is pretty average, meaning it's not cheaper, but it's pretty good. It has average pricing."
