CrowdStrike vs Expel: MDR Detection Speed Comparison

CrowdStrike Falcon and Expel are two of the only MDR providers that publicly disclose both detection and response time benchmarks. This makes them uniquely comparable in a market where most vendors rely on qualitative claims rather than quantitative data.

The headline finding: Expel publishes a faster MTTR than CrowdStrike. But response time is not the only metric that matters, and the numbers require context to interpret fairly. This comparison examines what the data actually tells us—and where each vendor has genuine advantages.

The Published Metrics: Head-to-Head

Detection is nearly identical. Both vendors detect threats in single-digit minutes—4 minutes for CrowdStrike, 5 minutes for Expel. This gap is negligible in practice.

Response is where they diverge. Expel's published MTTR of ~13 minutes for high-severity incidents is significantly faster than CrowdStrike's ~36 minutes. This is a real difference worth understanding.

Why the Response Time Gap Exists

The ~24-minute gap between Expel's MTTR and CrowdStrike's MTTR reflects genuine architectural differences, not just measurement methodology:

CrowdStrike: Unified Platform, Full Remediation

CrowdStrike's ~37-minute MTTR represents end-to-end response on a unified platform. CrowdStrike analysts operate the same Falcon agent that generated the detection. They can kill processes, quarantine hosts, remove persistence mechanisms, and restore systems—all through a single console they fully control.

The 37-minute figure includes the complete response lifecycle: triage, investigation, containment, and remediation. CrowdStrike's 1-10-60 framework targets 1-minute detection, 10-minute investigation, and 60-minute containment as an outer bound.

Expel: Platform-Agnostic, Workflow-Optimized

Expel operates as a platform-agnostic MDR service. They don't own the endpoint agent—they integrate with whatever platform the customer uses (CrowdStrike, Microsoft Defender, SentinelOne, Palo Alto, etc.). Expel's speed advantage comes from highly optimized investigation workflows and their Workbench platform, which automates much of the triage and enrichment process.

Expel publishes rolling averages with defined reporting windows, providing unusual transparency. Their ~13-minute MTTR for high-severity incidents is measured from when Expel's system detects the threat to when containment actions are taken.

What This Means in Practice

Expel's faster MTTR is a genuine advantage if your priority is speed to containment. However, because Expel operates on top of your existing platform rather than controlling the endpoint agent directly, the scope and depth of their response actions depend on what the underlying platform allows. On a CrowdStrike endpoint, Expel can do everything CrowdStrike Complete can do. On a less capable platform, response options may be more limited.

CrowdStrike's unified model means there is no gap between detection and response capability—the same agent that sees the threat can execute any containment or remediation action. This eliminates integration-layer delays and ensures the MDR team has full authority to act.

Independent Validation: MITRE ATT&CK

This is CrowdStrike's strongest differentiator against Expel.

CrowdStrike participates in MITRE Engenuity ATT&CK evaluations at both the Enterprise level (testing the Falcon platform's detection coverage) and the Managed Services level (testing Falcon Complete's end-to-end managed response). No other MDR vendor in this comparison has been evaluated at the Managed Services level.

Expel has not participated in MITRE evaluations because their model is platform-agnostic—they operate on whatever endpoint platform the customer uses. The detection coverage in an Expel deployment depends on the underlying platform (which may itself have MITRE results). Expel's value proposition is their analyst team, workflows, and response speed—not the detection technology, which comes from the customer's existing stack.

What this means for buyers: If you need documented, independently validated proof that your MDR service can detect specific ATT&CK techniques, CrowdStrike provides this through MITRE. Expel provides it indirectly—by operating on platforms that have MITRE validation—but the MDR service itself has not been independently tested.

Architectural Difference: Platform vs. Service Layer

This is the fundamental strategic choice between these vendors.

CrowdStrike: Buy the Platform + MDR Together

CrowdStrike Falcon Complete is a vertically integrated solution. You deploy the Falcon agent, and CrowdStrike's MDR team operates it. There is one vendor, one agent, one console, and one escalation path.

Advantages:

• No integration complexity—detection and response are native
• Full agent authority for containment and remediation
• Consistent detection quality across all endpoints
• Single vendor accountability for the entire security stack
• FedRAMP authorized, HIPAA-ready, PCI DSS compliant

Trade-offs:

• You are committed to the CrowdStrike ecosystem
• Replacing CrowdStrike means replacing both platform and MDR
• Less flexibility to mix best-of-breed components

Expel: Bring Your Own Platform + Add MDR

Expel integrates with your existing security stack. If you already use CrowdStrike, Microsoft Defender, SentinelOne, or another endpoint platform, Expel adds a managed SOC layer on top without requiring you to change your underlying tools.

Advantages:

• Platform-agnostic—works with whatever you already have
• Faster published response times for high-severity incidents
• Transparent operations through the Workbench portal
• Can be added or removed without changing your endpoint platform
• Unusually detailed published performance metrics

Trade-offs:

• Response capability limited by what the underlying platform supports
• Additional vendor relationship to manage
• No built-in compliance certifications (depends on underlying platform)
• Detection quality varies based on which platform you use

Pricing Approach

CrowdStrike Falcon Complete

CrowdStrike bundles the endpoint platform and MDR service:

• Small organizations (50-250 endpoints): ~$15-30/endpoint/month
• Mid-market (250-2,500 endpoints): Volume discounts available
• Enterprise (2,500+): Custom pricing

This includes the Falcon agent, 24/7 SOC, threat hunting, and incident response.

Expel MDR

Expel prices based on integrations and data sources rather than per-endpoint, since they don't provide the endpoint agent. You pay separately for your endpoint platform (CrowdStrike, Defender, SentinelOne, etc.) and then add Expel's MDR service on top.

This means Expel's total cost = your existing platform cost + Expel's MDR fee. For organizations already running a major endpoint platform, adding Expel may be comparable to upgrading to CrowdStrike Falcon Complete. For organizations starting fresh, CrowdStrike's bundled approach may be more cost-effective.

Decision Framework

Choose CrowdStrike Falcon Complete If:

• You want a single vendor for both platform and managed service
• Independent MITRE validation at the MDR level is important for compliance or due diligence
• You need built-in compliance certifications (FedRAMP, HIPAA, PCI DSS)
• You prefer unified platform authority—one agent, one console, full remediation capability
• You're starting fresh without an existing endpoint platform

Choose Expel MDR If:

• You already have an endpoint platform you want to keep
• Published response speed is your top priority (~13 min vs. ~36 min)
• You value operational transparency and detailed performance reporting
• You want the flexibility to change your underlying endpoint platform without changing MDR providers
• Your compliance needs are met by your existing platform

Consider Both Together

Some organizations use CrowdStrike Falcon as their endpoint platform and layer Expel's MDR service on top. This gives you CrowdStrike's detection technology with Expel's analyst workflows and response speed. It's a premium approach—you're paying for both—but it combines the strengths of each vendor.

The Bottom Line

Expel and CrowdStrike both represent the top tier of MDR transparency. In a market where most vendors won't publish a single response time metric, both publish detection, response, and remediation benchmarks. That alone separates them from the majority of the market.

Expel wins on speed: ~13-minute MTTR vs. CrowdStrike's ~36 minutes for high-severity incidents.

CrowdStrike wins on validation: The only MDR vendor with MITRE Managed Services evaluation results, plus unified platform control and built-in compliance certifications.

Both win on transparency: Publishing concrete benchmarks when most competitors don't.

The right choice depends on whether you prioritize verified detection coverage with unified platform control (CrowdStrike) or the fastest published response times with platform flexibility (Expel). Neither is the wrong answer—both are in the top tier of a market where most vendors won't show you their numbers at all.
