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.

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

"Palo Alto is the core of the security infrastructure in the environment."
"Their XDR agent and their behavioral indicators of compromise (BIOC) are pretty nice. Their managed threat hunting is also pretty nice. They also have WildFire, which is a service for actively looking for malware. It's quite useful."
"The user interface of the solution is sophisticated and straightforward."
"It can automatically correlate events and logs, which is very helpful for an IT administrator. It can correlate different kinds of malware activities over a network, agent, or host system. You do not need to do it manually. It is a good feature. It is also a user-friendly solution. We have deployed it on the cloud because our space does not provide any flexibility for on-premises deployment, but Palo Alto has added some flexibility to install it on-premises. It must be like the same Cortex XDR agent for all the VPN services, web filtering services, and everything else."
"In one single alert, we are getting the network telemetry, endpoint telemetry, email security telemetry, and proxy telemetry all in one single ticket, making it very easy."
"Cortex XDR is a simple platform that's easy for administrators and users. You have a lot of flexibility to change or customize the features."
"Cortex XDR is stable, offering high quality and reliable performance."
"The behavior-based detection feature is valuable."
"FortiXDR is valuable for its integration capabilities with one hundred percent compatibility with other vendors in cloud environments like Google, Oracle, and Microsoft."
"The most valuable feature of FortiXDR is its ability to block clients, providing comprehensive endpoint protection."
"The most valuable feature of FortiXDR is it integrates well with other Fortinet solutions, such as Fortinet firewall, FortiMail, FortiSandbox, Forti Fabric, switches, and access points. Whatever the flow of the traffic comes in or goes out, the entire traffic can be managed and monitored properly."
"The product is stable enough."
"Our customers are satisfied with FortiXDR."
"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."
"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."
"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."
 

Cons

"It would be good to have a better way to search for a file within the UI."
"If he is using a smaller company, he can depend on some other tools because Cortex XDR by Palo Alto Networks is a bit expensive."
"Based on our experience so far, its implementation is quite complex."
"It is an enterprise-level solution. Its price could be less expensive."
"The solution should force customers to integrate with network traffic to see the full benefits of XDR."
"Cortex XDR by Palo Alto Networks could improve by offering remote management. It would be useful to look at the client's issue to fix it."
"Currently, if you use Palo Alto endpoint protection as the only solution it's very complicated to remove pre-existing threats."
"There are some false positives."
"They could change their licensing costs to make it more affordable for smaller businesses."
"Many of the solutions, such as CrowdStrike have an MDR solution where remediation can be provided by the vendor. For example, if there is any zero data threat found, a new threat that the customer is not able to recognize, fix, or understand what needs to be done this feature has to be added in FortiXDR so that the customer feels comfortable."
"The pricing of FortiXDR should be improved. It's a point of concern for us."
"Improvement is needed in the intuitiveness and integration measures of FortiXDR, especially in terms of compatibility."
"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

"This is an expensive solution."
"The tool's price is moderate."
"Cortex XDR by Palo Alto Networks is an expensive solution."
"I feel it is fairly priced."
"If one wishes to work with another team or large number of users at a future point, he must purchase a license for them."
"Very costly product."
"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."
"It has reasonable pricing for the use cases it provides to the company."
"This is an expensive solution compared to other vendors, such as Check Point."
