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.

Centralized monitoring has improved threat visibility and reduced incident response time
In terms of valuable features in ESET EDR/XDR, we focus on endpoint device management as well as for the firewall team, including our log analysis and monitoring the firewall, which are three significant functions for us. ESET EDR/XDR has automated threat detection that gives us real-time incident alerts, and it helps us proactively receive and work on incidents that could have an impact. Regarding the usefulness of ESET EDR/XDR's behavior-based analysis in detecting potential breaches, we have identified some files or configuration files that should remain static, and if any changes occur without proper change management, we are able to identify those changes, including detecting zero-day attacks. The integration of threat intelligence feeds has helped our response strategies, as we are using Oracle OCA-based data analysis, and we have integrated it so that logs are forwarded to our SIEM, allowing us to analyze the data effectively. I evaluate the impact of centralized management on our security operations as very useful because it eliminates the need to log into individual systems to find sources, allowing us to identify all types of risks and vulnerabilities from a single desk.

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

"The solution's most valuable feature is the user interface."
"The user interface of the solution is sophisticated and straightforward."
"The most valuable features are the fact that it was running in the background and it would intercept any weird stuff, and the fact that it would send things directly to the cloud for sandboxing. It's quite practical."
"The positive impacts I see from Cortex XDR by Palo Alto Networks include a complete 360-degree view of our security posture altogether, being a uniform platform where we are ingesting logs from multiple resources."
"We think that this product will help us grow, as it meets our needs currently and we can grow with it over time."
"The anti-exploit is impenetrable."
"Traps has drastically reduced our endpoint attack surface via advanced detection capabilities, sandboxing of never before seen programs, and by drastically limiting where executables can launch in the first place."
"The solution allows us to gain remote access without the user's knowledge and take the necessary actions on the device."
"It is pretty easy to install without any hassles, and ESET EDR_XDR has its own cloud portal where everything is available."
"ESET EDR/XDR has automated threat detection that gives us real-time incident alerts, and it helps us proactively receive and work on incidents that could have an impact."
"The solution is easy to use."
"The initial setup of ESET EDR_XDR is very simple, easy to deploy, and manage."
"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 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."
"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."
 

Cons

"It is not very strong in terms of endpoint management. It should have additional features like DLP, encryption, or advanced device control. Currently, Cortex is good in terms of the security of the endpoints, but it is not as good as other vendors in terms of the management of the endpoint."
"It is not easy to sell Cortex XDR, not because it isn't a good tool. Its marketing needs to be improved."
"I would rate it an 8 rather than a 10 mainly because there is still room to improve the user experience around complex investigations, including alert tuning and third-party integration."
"It should support more mobile operating systems. That is one of the cons of their infrastructure right now."
"The downsides of Cortex XDR by Palo Alto Networks are that in many incidents, when I enter the causality chain, there are numerous logs."
"Additionally, I think the price is very high, and if it can be adjusted, I believe it will be a very good solution."
"There are some false positives. What our guys would have liked is that it would have been easier to manipulate as soon as they found a false positive that they knew was a false positive. How to do so was not obvious. Some people complained about it. The interface, the ESM, is not user-friendly."
"The installation should be easier and the Palo Alto pre-sales and sales teams should have more information on the product because they don't know what they are selling."
"ESET EDR_XDR needs to conduct more research and development and innovations in early detection of attacks."
"The memory and CPU footprint can affect performance. It sometimes slows down the CPU performance."
"The solution could improve how it scours each website."
"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

"It has reasonable pricing for the use cases it provides to the company."
"This is an expensive solution."
"I don't recall what the cost was, but it wasn't really that expensive."
"The pricing is a little bit on the expensive side."
"The price is on the higher side, but it's okay."
"The return on investment is from the user side because we have seen the performance of it increase the delivery time of the product if we are using too many web-based and on-premise applications. In indirect ways, we saw the return of investment in terms of performance and user satisfaction increase."
"We pay about $50,000 USD per year for a bundle that includes Cortex XDR."
"Cortex XDR’s pricing is very reasonable."
"I rate the solution’s pricing a six or seven out of ten.."
