Senior Process Expert at A.P. Moller - Maersk
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.

Setup is smooth and management is seamless, while improvements in email filtering transparency enhance efficiency
For data correlation, we just haven't worked long enough with it to assess its impact on our overall threat response strategy. We prefer a system that simply informs us when there is a problem; we don't want to engage too much in threat hunting. Therefore, we're not looking to create a SOC from this, which is also why we moved from XDR to MDR. There are areas for improvement, including the difficulty in getting the right handles on the applied email filters. It's sometimes unclear why one email is treated as spam and another is not, even if they contain similar content. Making the process of how emails are treated a bit more transparent would be beneficial.

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

"Once you become familiar with it, Cortex XDR by Palo Alto Networks is a more powerful tool and I would say that I prefer it over MDE because it is a stronger tool for me."
"The level of security I get for my endpoints and servers is extremely valuable."
"Since they've done their most recent update, the ease to isolate endpoints is valuable. If we find one where there is a virus on it, we can easily isolate it. We don't even have to contact the user. We don't have to manually take them off the network. We can easily isolate them."
"Previously, we had to install endpoint protection per machine and then scan and update, but Cortex XDR basically does that centrally and predictably, so we have more time to do day-to-day work rather than spend time chasing those endpoints."
"It detected stuff that other things wouldn't detect."
"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."
"If the user leaves our premises or network, Palo Alto Traps will still be on that endpoint and will still apply our policies."
"One of the main benefits of the solution is its intelligence to correlate the events into an incident."
"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."
"Since then, we are working with it, and so far, we have no problems; it's working smoothly with email security."
"I would rate GravityZone XDR more than nine out of ten."
"It provides an in-depth analysis and gives recommendations, along with a historical search capability."
"I appreciate the overall utilization of AI to enhance security posture."
"The solution has an automatic patch management capability."
"The HyperDetect feature in GravityZone XDR is effective."
"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."
"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 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."
"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."
"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."
 

Cons

"There are some limitations on the Traps agents."
"It should support more mobile operating systems. That is one of the cons of their infrastructure right now."
"I have run into some detection issues with Cortex XDR. It needs to be better at detection of internal attacks."
"The tool needs to be improved in terms of integration and interface."
"The playbooks could be improved to include more functionalities or actions."
"Cortex XDR could improve its sales support team, including better commission structures and referral programs."
"There's an overall lack of features."
"Cortex XDR by Palo Alto Networks can improve mobile integration to allow access to the console."
"Another area of improvement is CPU utilization. CPU utilization could be improved."
"The resource consumption is high for Bitdefender GravityZone XDR, nearly using one gigabyte of RAM, especially on Windows 10 and 11."
"The solution’s pricing could be improved."
"It's not very mature, and additional costs are involved."
"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."
"There are areas for improvement, including the difficulty in getting the right handles on the applied email filters."
"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

"Cortex XDR’s pricing is very reasonable."
"Licensing for Palo Alto Networks Cortex XDR can be costly, especially when it comes to a hundred users. A license is required for each user, and the subscription must be renewed on a yearly basis."
"Our license will require renewal in August, after which the maintenance will continue as usual."
"I don't like that they have different types of licenses."
"I am using the Community edition."
"I don't have any issues with the pricing. We are satisfied with the price."
"If one wishes to work with another team or large number of users at a future point, he must purchase a license for them."
"In terms of the cost Cortex XDR by Palo Alto Networks is very expensive because we are a Mexican company and when you translate dollars to pesos the cost is very high. The solution is very expensive for Mexican companies. I understand that they have international prices, but I do not think it offsets the price enough for many companies in countries, such as Mexico. The amount it is reduced is not a massive percentage."
"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."
"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."
