These 16 regularly surface across buyer review hubs and shortlists for MDR programs that want faster containment, cleaner evidence, and minimal stack disruption.

1. CrowdStrike Falcon Complete

CrowdStrike Falcon Complete fits teams that want MDR tightly coupled to one stack: detections, hunting, and host-level actions live natively in Falcon, so containment (and Rollback, where supported) moves fast without glue code.

• Single-stack speed (everything lives natively in Falcon)
• Decisive endpoint control, incl. Rollback on eligible Windows
• OverWatch human hunting on Falcon telemetry
• Operational coherence: cases/evidence/actions inside Falcon
• Global intel feeding detections and response
• Scales into identity, cloud, and NG-SIEM

Verify: lock-in/cost as you add Identity/Cloud/NG-SIEM; fusion depth for non-Falcon IdP/SaaS signals.

CrowdStrike pricing is typically ~$90K–$400K+/year (field benchmark), quote-based. Public per-endpoint list prices apply to EDR/XDR software, not the Falcon Complete MDR service.

CrowdStrike rating: ~4.6/5 across categories on G2.

2. Arctic Wolf: Concierge SOC

Arctic Wolf serves programs that want an assigned team running security as a cadence: a named Concierge Security Team, documented runbooks, posture hardening, and 24×7 case handling across endpoint, identity, cloud, and network.

• Named ownership via a Concierge Security Team that knows your estate
• Cadence as a control (weekly/monthly/QBR) to retire noise and harden posture
• 24×7 monitoring with documented handoffs
• Runbook-first operations (written, versioned, continually updated)
• Integrated hygiene/hardening, not just alert handling

Verify: what’s base vs add-on (cloud/identity/retention) and depth of third-party tool tuning beyond baseline configs. 

Arctic Wolf runs a strong concierge SOC, but certain needs are typically outside core scope or handled via adjacent services: deep fine-tuning of your existing tools for maximum value, full on-your-behalf IR/containment/remediation, bespoke playbooks in your SOAR of choice, and offensive security (penetration testing/ethical hacking).

Arctic Wolf pricing is ~$30K–$320K+/year. The cost range is extensive here, and you can learn what determines it in this article.

Arctic Wolf rating: Gartner — 4.9/5.

3. UnderDefense MDR

UnderDefense is for bring-your-own-stack teams that want their existing tools to operate like one system: we normalize telemetry, tune detections on your data, and execute pre-approved actions with audited rollback through your SOAR/ITSM.

• 360° visibility across endpoint, identity, SaaS, cloud, and network—one fused picture instead of five portals.
• Deep tuning of your EDR/IdP/SaaS/cloud to cut false positives and retire overlapping controls.
• Custom IR plan & playbooks: action ladders (isolate/disable/revoke) defined up front; tickets open/close in your queues with write-backs.
• Proactive hunting focused on your top attack paths; evidence exported as one clean incident narrative for audit/board use.

How our proactive hunt plays out:

During a proactive hunt for a top-10 U.S. government-finance org, we caught successful VPN logins from atypical countries that “baseline” rules missed (low-and-slow brute-force on legacy/default accounts + weak passwords). 

We worked overnight to block risky geos, disable the compromised account set, and tighten MFA, password, and VPN policies. We also shipped new correlation rules and a hygiene cadence (account audits, offboarding checks). Outcome was six abused VPN accounts identified, quiet access cut off, and durable controls in place. Read the full case.

UnderDefense pricing is in the ~$60K–$240K+/year range. For a tighter estimate on your estate, use the MDR Cost Calculator to model endpoints, log volume, retention, and response ladders.

UnderDefense rating: G2 — 5.0/5.

4. Expel MDR

Expel leans into transparency-first MDR: plain-English investigations in Workbench, broad third-party ingest, and a human+automation split that makes ownership and next steps obvious, without forcing a platform transplant.

• Readable timelines in Workbench (“what we saw/did/what to do next”).
• Broad integrations across EDR/IdP/SaaS/cloud; strong Microsoft ecosystem comfort.
• 24×7 SOC with clear escalation paths; actionable guidance, not just alerts.
• Balanced automation + analyst oversight to keep noise low and actions defensible.
• Evidence exports you can hand to leadership and audit.

Verify: case system-of-record (their portal vs your ITSM), bi-directional SOAR/ITSM write-backs, pre-authorized actions + audited rollback, scope of non-Microsoft depth, and retention windows.

Expel is an investigations-first MDR. Commonly out of scope are compliance evidence implementation, vulnerability scanning, deep fine-tuning of your existing tools, full on-your-behalf IR/containment/remediation, and offensive security.

Expel pricing typically lands around ~$90K–$350K+/year (field benchmark), quote-based.

Expel rating: G2 — 4.7/5.

5. Fortra Alert Logic MDR

Built for hybrid and cloud estates, Alert Logic emphasizes pragmatic time-to-value: managed sensors/logs, 24×7 SOC, and packaging that reduces heavy SIEM plumbing, especially attractive for AWS-centric programs.

• Fast activation for cloud/hybrid without a big SIEM build-out.
• Managed detection across logs/sensors/cloud; pragmatic coverage.
• AWS-native comfort and marketplace-friendly buying paths.
• Playbooks for common cloud/web app threats and noisy controls.
• Ongoing posture reviews to convert findings into changes.

Verify: identity/EDR fusion depth (not just logs), ITSM/SOAR write-backs, pre-auth action ladders + rollback, what’s base vs add-on for cloud accounts/data sources, and retention tiers.

Fortra Alert Logic MDR focuses on detection/monitoring around its own stack. Typically not included: deep fine-tuning of your third-party tools and hands-on IR/containment/remediation.

Alert Logic pricing typically falls around ~$25K–$150K+/year (field benchmark), quote-based. 

Alert Logic MDR rating: G2 — 4.5/5.

6. eSentire: Open XDR MDR

eSentire is an investigations-led MDR with an Open XDR posture: strong Microsoft alignment (Sentinel/Defender/O365), 300+ integrations, and exportable narratives that braid endpoint + identity + SaaS into one case you can actually reuse.

• Broad ingest with Microsoft-stack depth (Sentinel + Defender suite).
• Human-led investigations producing concise, exportable incident stories.
• 24×7 SOC and proactive hunting; aggressive time-to-contain targets.
• Enterprise-grade integration catalog to meet heterogeneous estates.

Verify: ITSM/SOAR wiring and where cases “live,” pre-authorized actions + rollback authority, parity across non-Microsoft sources, evidence format/retention, and any pro-serv for custom use-cases.

eSentire pricing is around ~$80K–$300K+/year (field benchmark), quote-based.

eSentire rating: G2 lists eSentire at 4.7/5

7. Sophos MDR

Sophos treats MDR like a fresh deployment with a deliberate two-path setup: Essentials (they assist/contain, you remediate) or Complete (they fully remediate 24×7). If you want fast activation, plain ownership lines, and a Defender-friendly path without ripping out controls, Sophos is built for that.

• Two response modes by contract (Essentials vs Complete)
• Quick time-to-green; sensible day-1 containment defaults
• Microsoft-heavy estates supported without rip-and-replace
• Straightforward per-user/per-server packaging; simple comms for IT/helpdesk

Verify: parity on Microsoft Defender signals vs native Sophos telemetry, where cases “live” (vendor portal vs your ITSM), and how third-party IdP/SaaS gets correlated into a single incident record.

Sophos pricing is usually ~$40K–$120K+/year (field benchmark) or ~$28–$48 per user/year for software tiers with a managed uplift.

Sophos rating: G2 — 4.6/5.

8. Secureworks Taegis MDR

Taegis MDR gives you open integrations plus tiered ownership (MDR → Plus → Enhanced) so you can dial how much Secureworks runs: from core investigations to phishing queue coverage and advisory/governance. A fit when you want to open MDR that can push cases into your ITSM and write back to your SOAR.

• Tiered control: add custom workflows/use-cases (Plus) and higher-touch ops/governance (Enhanced)
• Broad SIEM/EDR/IdP integrations; portal with options to operate in your pipelines
• 24×7 investigations (endpoint/identity/SaaS) with phishing queue absorption at higher tiers

Verify: single-pane ownership (case created in Taegis → assigned/closed in your ITSM with rollback notes), and pre-authorized action ladders.

Taegis MDR pricing is typically ~$50K–$250K+/year (field benchmark), quote-based.

Taegis MDR rating: G2 — 4.6/5 (≈47 reviews).

9. Red Canary: Overlay MDR

Red Canary overlays MDR on the stack you already run and tells a clean, exportable story: readable investigations that braid endpoint + identity + SaaS into a single narrative your execs will actually use, now with growing ties to Zscaler’s Zero Trust Exchange post-acquisition.

• Narrative as a deliverable: concise “cause → scope → actions → owner” timelines
• Strong identity/SaaS emphasis (M365/Google/Okta), where many MDRs stay endpoint-centric
• Overlay mindset: keep your EDR; they integrate and operate on top
• Consistent investigation notes you can paste into audits/board packs

Scope note: Red Canary investigations-first MDR, typically not a home for compliance evidence implementation, vuln scanning, deep tool fine-tuning, full on-your-behalf remediation, or offensive security.

Red Canary pricing is around ~$60K–$250K+/year (field benchmark), quote-based.

Red Canary rating: G2 — 4.7/5.

10. SentinelOne Vigilance Respond Pro

SentinelOne Vigilance layers 24×7 analysts on top of SentinelOne Singularity EDR/XDR so host-level actions happen inside one stack — detected, hunted, and contained in Singularity — with Rollback available on eligible Windows scenarios. If you want decisive endpoint control without glue code, this is the “EDR-native” lane.

• One stack from alert→action: detections, context, and response live natively in Singularity
• Rollback (Windows, supported cases) for restore after containment
• Managed hunting tied directly to Singularity response actions
• Opinionated defaults that keep the helpdesk impact low during containment

Scope note: prove seams off-endpoint: bring an IdP/SaaS signal into the storyline (not just an attachment), validate SOAR/ITSM write-backs, and confirm pre-authorized actions + audited rollback in practice.

SentinelOne pricing is ~$17–$50 per endpoint/year on top of your SentinelOne EDR license (often totals ~$30K–$110K+/year for the EDR software, then Vigilance uplift), quote-based.

SentinelOne rating: G2 — Singularity XDR listed at 4.9/5.

11. Huntress: Managed EDR / MDR for Lean IT

Huntress Managed EDR is the straight-shooting option for SMB and lean IT teams: opinionated endpoint playbooks, 24×7 SOC, and plain language reports. It coexists cleanly with Microsoft Defender and keeps pricing simple per endpoint.

• Endpoint-first decisiveness (isolate/kill/remediate fast)
• Works alongside Microsoft Defender to add managed response discipline
• Clear, plain-English timelines leaders can reuse

Scope note: pair with SIEM/XDR if you need deep identity/SaaS fusion, compliance evidence packs, or broad third-party telemetry.

Huntress pricing is often ~$8K–$50K+/year, depending on fleet size/modules (field benchmark), quote-based.

Huntress Maganed EDR rating: G2 — 4.9/5.

12. Tenable

Tenable centers security on exposure management (Tenable One / Tenable VM / Tenable.sc / Nessus) and is often paired with an MDR provider for hands-on response. Choose it when the priority is shrinking attack surface, risk-based vuln prioritization, and cloud/OT visibility rather than a “do-it-for-you” MDR.

• Risk-based vulnerability management and exposure insights that drive practical remediation and MDR playbooks
• Broad asset and attack-surface coverage across cloud, on-prem, and OT/IoT environments
• Commonly used as a telemetry/exposure backbone that partners layer managed detection/response onto

Tenable isn’t a classic MDR. If you want on-your-behalf containment/remediation, deep fine-tuning, or offensive security, you’ll typically add Tenable Managed Services or a partner MDR around the exposure stack.

Tenable pricing commonly lands ~$40K–$200K+/year (field benchmark).Tenable rating: G2 — Tenable Vulnerability Management 4.6/5.

13. Bitdefender MDR

Bitdefender MDR wraps the GravityZone stack with 24×7 SOC and global labs intel, giving you decisive host-level actions, pragmatic hunting, and one vendor for EDR + managed response. It’s a match when you want MDR tightly aligned to Bitdefender controls without stitching multiple platforms.

• GravityZone-native detections and response with SOC oversight
• Global threat labs/intel feeding investigations and tuning
• Program reviews to convert findings into configuration changes

Validate: third-party ingest/write-backs (IdP/SaaS/ITSM/SOAR), pre-auth authority + rollback, and evidence exports your audit/board will accept.

Bitdefender MDR pricing is commonly ~$50K–$220K+/year (field benchmark), quote-based. 

Bitdefender MDR Rating: G2 — 4.5/5

14. Critical Start MDR

Critical Start is a Microsoft-friendly MDR with opinionated noise reduction (Trusted Behavior Registry), a Zero-Trust Analytics Platform (ZTAP), and a MOBILESOC app for on-the-go approvals and actions. It’s a fit when you want fast triage discipline, strong Defender/XDR alignment, and human SOC backed by prescriptive playbooks.

• Trusted Behavior Registry + ZTAP to drive alert resolution and reduce false positives
• Defender-centric depth; broad integrations (endpoint, SIEM/XDR, identity)
• MOBILESOC app for real-time case handling and approvals

Verify: confirm bespoke fine-tuning depth across your non-Microsoft tools, pre-authorized action ladders with audited rollback, and where cases live (their portal vs your ITSM) for clean ownership.

Critical Start MDR pricing is around ~$70K–$250K+/year (field benchmark), quote-based.

Critical Start MDR rating: Gartner — 4.5/5

15. Kroll Responder MDR

Kroll’s Responder MDR pairs 24×7 monitoring with Kroll’s DFIR muscle: seasoned incident handlers, threat hunting, and rapid containment backed by the same team that runs high-stakes breach response and forensics globally. If you want investigations that can escalate straight into expert-led IR without a vendor shuffle, this is that lane.

• DFIR-backed investigations with direct surge to Kroll incident responders
• Multi-signal coverage (endpoint/identity/SaaS/cloud) with human-led triage
• Playbooks oriented to fast isolation/disable/revoke and clean evidence packages
• Threat hunting informed by active case intel across Kroll engagements

Scope note: buyers typically add clarity on deep fine-tuning of your existing tools, bespoke SOAR playbooks in your system of record, and whether offensive security (pentest/adversary emulation) is bundled vs. separate.

Kroll’s Responder MDR pricing is commonly ~$30K–$200K+/year (field benchmark), quote-based.

Kroll’s Responder MDR Rating: Gartner — 4.6/5

16. BlueVoyant MDR

BlueVoyant runs MDR with a strong Microsoft/Splunk/Cisco delivery focus and a “operate on what you already own” posture: 24×7 investigations, hunting, and response wired into the tools you’ve standardized on (especially Microsoft Sentinel/Defender), so you get clear case ownership and repeatable handoffs without a platform transplant.

• 24×7 SOC with human investigations and pragmatic runbooks
• Deep Microsoft track record (Sentinel/Defender) and services depth; strong Splunk/Cisco XDR options
• Broad coverage across endpoint/identity/SaaS/cloud with exportable incident narratives
• Program reviews that turn findings into tuned rules and posture changes
• Threat intel + automation to reduce noise and accelerate containment

Scope note: BlueVoyant emphasizes operating your chosen stack and managing investigations/response. If you need extensive bespoke fine-tuning or bundled offensive testing, confirm how those are delivered.

BlueVoyant MDR pricing is typically ~$70K–$280K+/year (field benchmark), quote-based.

BlueVoyant MDR rating: Gartner — 4.5/5.

Choose an MDR That Feels Like Part of Your Team

Security shouldn’t feel complex.

At UnderDefense, we shape defenses to your world, 24/7, until the job is done.

• We accelerate detection and give you 360° visibility across endpoint, identity, SaaS, cloud, and network.
• We protect every attack surface, without forcing a platform swap.
• We move in minutes: pre-approved actions with audited rollback, not promises.
• We can augment your SOC or operate as your external SOC.
• We run the tools you already use and love, and tune them to perform.

This is how we run MDR. If you have a SOC, we augment it; if you don’t, we are it. You keep ownership; we add velocity and judgment.

The result is felt more than announced: 

• 2-minute alert-to-triage, 
• ~15-minute minutes-to-contain, 
• false positives collapsing by 99%.
• Customers notice: 98% satisfaction over six years, and no one has left.

Our defense is about actions.

One night, a global firm that serves government clients saw “background noise” on its servers. It was Cobalt Strike, already moving laterally, 11 systems in. We tuned their SIEM, cut four hours of triage to one minute, hunted, confirmed beaconing, contained the threat, cleaned every affected system, and tightened IdP and VPN policies. We also shipped lasting correlation rules. Within 24 hours, they were back online and quieter than before.

“You feel like part of our team,” their head of IT told us. That’s the point.

If this is how you want security to run — owned by you, accelerated by us — bring us into your proof. Let the story above play out on your data, in your tools, at your speed.
