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.

Integration of multiple firewalls enables advanced threat detection
The integration of data from firewalls and Active Directory is most valuable. Cybereason XDR facilitates two-way communication, where the firewall sends data to the Cybereason system, and it can communicate with the firewall to stop unwanted communication. Customers can deal with multiple types of firewalls with ease. The behavioral analytics help detect advanced threats when attackers use existing software. The multilayered protection approach, including NGAV, integrates XDR detection with antivirus to assess and counter threats effectively.

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

"Stability-wise, it is good; I did not hear about any issues in terms of stability, and Cortex XDR by Palo Alto Networks can be trusted completely."
"The tool is designed to scale for large enterprises and handle large volumes of data."
"Traps pays for itself within the first 16 months of a three-year subscription."
"Cortex XDR by Palo Alto Networks should be a stable solution."
"The stability is pretty good except for one or two cases, and based on the performance, it's been okay with pretty high performance, no bugs or glitches, and it doesn't crash or freeze."
"The level of security I get for my endpoints and servers is extremely valuable."
"The solution allows us to gain remote access without the user's knowledge and take the necessary actions on the device."
"Implementing Cortex XDR by Palo Alto Networks has had a significant impact on my security analyst workload because it becomes much easier."
"The integration of data from firewalls and Active Directory is most valuable."
"The solution has an investigation feature, which is useful for building storylines."
"Cybereason XDR's most useful feature is the investigation."
"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."
"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."
"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."
"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."
 

Cons

"A little bit more automation would be nice."
"Cortex XDR could improve its sales support team, including better commission structures and referral programs."
"I would like to see them include NDR (Network Detection Response). Then it would work well with SIEM Response."
"The deployment is pretty hard."
"In general, the price could be more competitive."
"One thing that was missing was the integration part. Currently, they don't have out-of-box integration with IBM QRadar, or if they have the integration, the integration doesn't work well."
"The product's pricing could be better."
"To jump from the partner to Palo Alto directly was challenging."
"There could be more integrations with other data sources like NDR systems."
"The one thing we sometimes have issues with is its integration with other security applications like antiviruses."
"Cybereason's customer support could be better."
"Customer service is rated as a five out of ten. When they work and reach the right level, they are helpful, but getting to the right person can be time-consuming."
"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."
"Cortex XDR by Palo Alto Networks is quite an expensive solution."
"The pricing is a little bit on the expensive side."
"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."
"Cortex XDR's pricing is ok."
"It has reasonable pricing for the use cases it provides to the company."
"The pricing is a little high. It is per user per year."
"Our customers have expressed that the price is high."
"The solution is cheaper than Microsoft Defender. It has a subscription and no standard license."
