With Cortex XDR by Palo Alto Networks' incident correlation, behavioral detection, and process tree visibility, similar initial triage can often be completed in roughly 10 to 20 minutes, depending on the incident.
They appreciate the rich telemetry data from the solution, as it provides in-depth threat identification.
Cortex XDR by Palo Alto Networks helps to reduce my total cost of ownership significantly.
The workload has been reduced and the ROI has improved by around 20 percent.
I have seen a return on investment because, in terms of employees, 15 were cut down to eight, and it was also saving us time from the whole dashboard automation.
Trellix helped us save our information, which is the most critical, and also save money.
Log triage no longer takes up our security team's calendar, allowing those hours to go into platform architecture, our DRM protections, and proactive hardening.
Each alert comes with the caller, the endpoint, and the queries, so we do not dig through logs.
I have seen a return on investment, mainly in time and not having to build a team, as we did not need to hire a security team to get around-the-clock cloud coverage.
The technical support from Palo Alto deserves a mark of ten because they reach out within an hour whenever assistance is needed.
There is no back and forth, and they know what we are asking for and come up with the best resolution for a solution.
If any of these services are missed, it becomes a problem in terms of support tickets, follow-up, or special configuration that needs to be done in the system.
If I require remote support, they will send a link to join a session and help me resolve any issues I have faced.
Technical support is crucial, especially when facing critical issues.
The most basic thing that you need from the vendor is support, and by the time they resolve it, you probably would have figured it out by yourself because the resolution came after weeks or months.
When we needed a baseline adjusted or a finding explained, we got a clear answer quickly.
I would rate the customer support on a scale of 1 to 10 as 10.
The customer support has been responsive and helpful.
You can onboard 10,000 endpoints in just hours, which demonstrates the excellent scalability of this product.
Activating the newly purchased licenses is instantaneous, allowing installations without adjustments since it's cloud-based.
Cortex XDR by Palo Alto Networks can be expanded anytime by purchasing another license without any issues related to scalability.
Trellix XDR has good scalability because it can handle multiple security sources and multiple logs.
in our environment, we have fed a lot of data logs into the tool, and it has been reliable and scalable with no issues.
You can scale from ten licenses to several thousand.
Our platform sees sharp spikes from bulk uploads and fast-spreading assets, and UnderDefense Agentic AI SOC handles them without needing us to resize or retune anything.
UnderDefense's scalability is good, as the same coverage applies as our cloud environment grows without us changing anything on our side.
Our traffic is high, and UnderDefense handles it without us changing anything.
Cortex remains fast and responsive, even with increasing data and alerts.
The thresholds we've seen on our firewall boxes at some instances reached 80% to 85%, but even at that level of utilization, we don't observe any latency or any issues reported with respect to accessing the application.
Cortex XDR by Palo Alto Networks can be trusted completely.
Support and stability are good. They are continuously improving.
The system would go down for half an hour, an hour, or two hours in the off-hours which would then impact the business, impact the alerts, and the flow of alert.
There is no downtime, or if there is, prior notification is sent to us so we can prepare accordingly.
We use it every day and it has run steadily, including when our traffic is high.
Improving reporting and dashboard customization, along with the addition of real-time and exportable reports, would help SOC teams greatly.
When a Cortex XDR by Palo Alto Networks incident is confirmed, it would be useful to automatically create a ServiceNow or Jira ticket with the incident summary, including affected endpoints, user indicators, process tree, severity, and recommended response actions.
The inclusion of this feature would allow the application of DLP policies alongside antivirus policies via a single agent and console, making it more competitive as other OEMs often offer DLP solutions as part of their antivirus products.
Trellix support team is not highly regarded because they follow a whole hierarchical process to escalate the complaints and the feedback requests, and the resolution can take very long, from two to three weeks to a month, which is not really viable in a cybersecurity landscape which is moving this fast.
Continuous enhancement to automation and AI-driven threat prioritization would further reduce analysts' workflow and improve response effectiveness.
The trend these days is moving toward AI security, and Trellix XDR should align with this direction.
It is worth it for accurate triage later, but a template for common upload patterns will shorten that time.
The setup and daily use have both been smooth.
Showing the customer name in the alert would help.
The pricing on SentinelOne is far more reasonable and cheaper than Cortex XDR by Palo Alto Networks.
I would say it is definitely not a cheap product, considering how mature it is and how scalable all Palo Alto products are together.
Compared to CrowdStrike, which is very costly, and SentinelOne, which is also very costly, Cortex XDR by Palo Alto Networks is a medium cost-efficient solution.
But currently, they have bumped up the prices and that is why we have now moved to a different solution totally. We have left Trellix XDR.
My experience with pricing, setup cost, and licensing shows that the pricing is very competitive and not overly expensive.
licensing was clear from the start, giving me good value for the price
Compared with building the same coverage in-house, it is a much lower cost and did not require us to hire.
Pricing was fair for what we get, setup was easy and took very little of our time, and the licensing was clear from the start, enabling us to see good value for the price.
It incorporates AI for normal behavior detection, distinguishing unusual operations.
The product provides automation responses in case of a threat attack, severity assessments, centralized manageability, and comprehensive compliance features, resulting in reduced costs.
It includes machine learning to easily analyze data and detect complex threats across endpoints, networks, or clouds.
The core functionality includes EDR and NDR, and Trellix XDR gets threat detection on both the network and endpoint levels.
The second feature is its ability for cross-platform threat correlation, meaning the platform helps to correlate all events across endpoints, network activity, security controls, and threat intelligence sources, providing us with a more in-depth view in terms of threat detection and threat research.
You can start as a small company and when you own Trellix XDR, as your company grows, you can grow your Trellix XDR subscription from on-premise, for example, to the cloud.
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.
It has full-time support 24/7 with proactive reports, and monitoring runs around the clock.
The sorting signals and clear reports help my team day-to-day because 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.
