Cortex XDR vs. Microsoft Defender XDR

Microsoft Defender XDR might succeed at protecting Microsoft’s own systems, but this solution stumbles when preventing, detecting and responding to threat actors operating outside of their product’s closed ecosystem.

Cortex XDR is the better choice to stop modern threats

Microsoft Defender XDR’s fragmented XDR capabilities, reflected in its low threat detection rate, siloed data integration and intricate licensing system, leave organizations vulnerable to medium and advanced threats. Cortex XDR integrates Microsoft’s XDR features into one intuitive product. It delivers:

ML-powered behavioral analytics across multiple data sources
An industry-leading malware analysis sandbox to support your threat hunting
Network visibility that’s integrated into one unified, cloud-based console.

Consistent MITRE Leadership

In the 2024 MITRE Engenuity ATT&CK Evaluations (Round 6), Cortex XDR again excelled, preventing 8 out of 10 attack steps with zero false positives and achieving 80 technique-level detections – the highest among tested vendors. By contrast, Microsoft Defender XDR managed to block only 3 out of 10 attack steps and delivered just 57 technique detections.

Cortex XDR also recently outperformed Microsoft — and all other XDR vendors — in the 2023 MITRE Engenuity ATT&CK Evaluations (Turla).

Where does Microsoft fall behind Cortex XDR in tests?

Microsoft Defender XDR doesn’t meet the high visibility and detection requirements needed to effectively defend against today’s nation-state-backed threat actors.

2024 MITRE ATT&CK Evaluations (Round 6)

Cortex XDR demonstrated industry-best performance once again, blocking 8 of 10 attack steps with zero false positives, while Microsoft only blocked 3 of 10.
Cortex XDR achieved 80 technique detections – the highest coverage among the top 10 market share vendors – whereas Microsoft’s coverage was 57.

2023 MITRE ATT&CK Evaluations (Turla)

Microsoft posted a 78.3% analytic detection rate, compared to Cortex XDR’s 100.0% analytic detection rate.
Microsoft’s detection rate means that 21.7% of substeps taken by these cyber tools failed to result in an endpoint detection, while Cortex XDR detected all substeps.
Microsoft needed 39 detections via configuration changes, whereas Cortex XDR’s 100% rate came with zero configuration changes.

Cortex XDR achieves these results by:

Integrating with the WildFire® malware prevention service to detect unknown threats in a cloud analysis environment.
Leveraging behavioral analytics to profile behavior by tracking more than 1,000 behavior attributes.
Having behavior analytics, forensics and network visibility natively integrated into Cortex XDR.

Cortex XDR stitches together multiple data sources into one UI console for fast investigation and response.

Not Enterprise Ready: Microsoft Defender XDR Makes Third-Party Integration Hard

Microsoft Defender XDR excels when an organization needs to integrate, correlate and stitch data, incidents and alerts from Microsoft products. However, to fully integrate data on Microsoft XDR Defender from firewalls, web server logs, cloud logs or IAM products, customers are encouraged to purchase Microsoft Sentinel. Microsoft Sentinel isn’t included in any of their licenses, including 365, E5, E5 Security or E5 Mobility + Security.

Additionally, Microsoft Defender XDR is only partially able to ingest all identity data sources or network fabric data from common identity platforms like Duo or Okta. These limitations create the need for additional product purchases and reconfigurations.

In contrast, the Cortex XDR agent provides full XDR features out of the box. It comes with complete coverage for endpoints across Windows, macOS, Linux, Chrome OS and Android systems and across private, public, hybrid and multi-cloud environments, while Microsoft has more limited functionality on macOS, Linux and legacy Windows. This makes our third-party integration more open and flexible to the needs of growing organizations by:

Ingesting, mapping and using data from any number of sources that are delivered in standard formats like syslog or HTTP.
Automatically stitching together data from any source to reveal the root cause and timeline of alerts to identify and quickly stop threats.
Having Cortex XDR use that data to generate XDR alerts within incidents to quickly scale visibility across an organization.

Cortex XDR is a single solution that provides a unified view into threats while Microsoft Defender XDR has many products to purchase and deploy with multiple user consoles to manage.

A Single, Unified View into Threats

Microsoft Defender XDR requires the use of several different products and management consoles in order to achieve the full functionality that Cortex XDR provides. On its own, Microsoft Defender XDR has limited coverage across operating systems. Therefore, it relies on multiple siloed products, each with their own consoles and dashboards to navigate. Investigation time is increased and management is a burden.

Cortex XDR streamlines SecOps by offering a unified platform for detection and response, consolidating alerts and incidents into a single view. SOC analysts can efficiently prevent threats, identify and detect incidents and expedite investigations using a single, automated web-based console. Cortex XDR also includes vulnerability management and identity analytics, which don’t necessitate a partnership or specific connection module. In summary, Cortex XDR:

Provides one web-based console for detection and response that correlates alerts and incidents into a single view.
Uses Host Insights to combine vulnerability assessment, application and system visibility, machine learning and Search and Destroy to help analyze threats across all endpoints.

	Switching between several different consoles makes management overly complex and reduces SOC efficiency.	Automatic correlation of events lets analysts see the entire incident, reducing manual work.
	Lack of integration between threat prevention and detection consoles increases alert triage and investigation times and several detection queues to view makes management a burden.	Detection rules and dashboards are easily customizable to support each organization’s unique needs.
Enterprise Fit	Complex and costly with limited scope Heavy reliance on Microsoft systems, services and solutions with integration across non-Microsoft technology an afterthought.	Tailored to your organization Data can be ingested from virtually any syslog, event log, filebeat or source — enterprise-wide, across clouds and operating systems.

Cortex XDR consistently outperforms Microsoft Defender XDR in MITRE ATT&CK Evaluations

In the 2023 MITRE ATT&CK Evaluations, only 67.8% of the possible detections by Microsoft resulted in the highest level of detail (technique level detections), with the rest either missed entirely or providing an inferior level of detail about attack actions.

Cortex XDR delivered 100% threat protection and 100% detection of all attack steps for the second year in a row, with 99.3% of technique detections providing the highest level of detail into attack steps to enable analysts to more quickly and accurately respond to events.
