Microsoft Defender XDR and UnderDefense compete in the cybersecurity enhancement category. Microsoft Defender XDR holds the advantage in cost-effectiveness and support, whereas UnderDefense's premium pricing is justified by its exceptional, tailored features.
Features: Microsoft Defender XDR offers seamless integration with Microsoft products, advanced threat detection, and automated response. UnderDefense provides customized security solutions, emphasizing threat intelligence and proactive monitoring, making it appealing for enterprises seeking robust, tailored security.
Room for Improvement: Microsoft Defender XDR could enhance its compatibility with non-Microsoft ecosystems, improve threat intelligence outside its ecosystem, and expand its customizability for diverse threat landscapes. UnderDefense might improve its deployment speed, reduce complexity in setup, and streamline its cost structure for scalability.
Ease of Deployment and Customer Service: Microsoft Defender XDR benefits from a straightforward deployment process within the Microsoft ecosystem, offering ease and speed. UnderDefense provides comprehensive guidance and responsive support, though it may require more time for initial setup in complex environments.
Pricing and ROI: Microsoft Defender XDR is budget-friendly, offering value through bundled Microsoft services and a lower total cost of ownership. UnderDefense, while requiring higher initial investment, offers significant ROI due to its enhanced, bespoke security options, appealing to organizations prioritizing customized security.
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.
We can quarantine and isolate a device within minutes.
Microsoft Defender XDR has saved me at least 50% of my time.
It helped stop multiple intrusion points where we would have had millions in lost revenue if the attackers got in.
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.
You get stuck in low-level support for way longer than you should, instead of them escalating the issue up the chain.
It's critical to escalate SEV B issues immediately to a domestic engineer.
Once issues are escalated to the second or third layer, the support is much better.
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.
My concern is about the scale of events and alerts being generated, and the product is doing a very good job of only surfacing the important items for us.
It has a very good integration system that integrates with all Azure services, all threat intelligence data models, and integrates very well with other systems such as Palo Alto.
Microsoft Defender XDR shows tremendous scalability, much more so than on-premises solutions.
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.
The service has remained consistently online, with any issues isolated to specific components, suggesting a well-designed and modular architecture.
The services within our ecosystem have been reliable, meeting their SLAs.
It provides high-fidelity signals.
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.
The licensing process needs improvement and clarification.
Improvements are needed in automated response capabilities.
If you have a central location where you perform one isolation method, all other potentially affected systems that have been touched may also be isolated simultaneously.
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.
There are certainly savings when using Microsoft Defender XDR, which can range from 30%, 40%, and even up to 50%.
I would rate the pricing as eight out of ten, indicating it is a reasonable cost for the product.
Microsoft purposefully obfuscates this through marketing ploys to hide costs.
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.
With Microsoft threat intelligence information, it detects various types of threats, including insider attacks, malicious content, and data exfiltration.
This allows us to secure our systems in advance and proactively improve security, rather than waiting for incidents to occur.
Once we have it on the security dashboard, we can see a real-time storyline.
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.
