Armor Alternatives & Competitors
Why look for alternatives?
Armor may not be the best fit if:
- •Teams running macOS or mobile-heavy environments with no agent support for either
- •Buyers who need independent validation before committing. Only 12 public G2 reviews exist.
- •Organizations not on Microsoft Sentinel and Defender XDR, since coverage depends on that stack
Armor at a glance
Same Model: Platform vendor
13 providers with the same business model as Armor.
Rapid7
Full SIEM data access with managed MDR, analyst pod model for environment familiarity, and Active Response via Velociraptor. Trade-off: requires 80%+ Insight Agent coverage (platform lock-in), 500-asset minimum, and the company is navigating a challenging period with declining revenue guidance and activist investor pressure.
Rapid7 and Armor are both Platform vendors and both require their own platform.
Rapid7 covers 5 surfaces vs. 3 for Armor — broader coverage.
Sophos
Platform vendor with unusually broad third-party integration support (350+ tools), all-in pricing on MDR Complete with full IR and $1M breach warranty, and #1 G2 MDR ranking for 14 consecutive quarters. Key trade-off: requires Sophos agent for full capabilities, dashboard-only data access (no raw query), and the Secureworks acquisition creates product roadmap uncertainty.
Sophos and Armor are both Platform vendors and both require their own platform.
Sophos covers 5 surfaces vs. 3 for Armor — broader coverage.
Bitdefender MDR
MITRE-validated detection quality on a single-vendor GravityZone platform with 3 global SOCs and competitive per-endpoint pricing. The trade-off is full vendor lock-in to GravityZone, no third-party EDR support, and XDR sensor licenses that add cost if you need coverage beyond endpoints.

SentinelOne offers a breach warranty.
Cynet
Best fit for SMB/mid-market teams wanting an all-in-one security platform with transparent pricing ($7-10/endpoint/month) and MDR included. Trade-off is full platform lock-in (must replace existing EDR), small company scale, and absence from Gartner MQ/Forrester Wave.

ThreatDown and Armor are both Platform vendors and both require their own platform.
ThreatDown covers 1 surfaces vs. 3 for Armor.
Daylight Security
AI-native MDR that deploys in under an hour and works with your existing EDR. Founded late 2024, so zero independent reviews and no compliance certifications yet. Best for buyers comfortable with an early-stage vendor who want fast deployment and AI-driven triage over a proven track record.

Different Approach
25 providers that take a different approach to MDR.
Huntress
The most recommended MDR on r/msp for SMB environments. Human-led SOC with <1% false positive rate and 8-minute MTTR, follow-the-sun coverage, and a multi-product platform that consolidates EDR, identity, SIEM, and training under one vendor.
Huntress and Armor are both require their own platform and both target Mid-market organizations.
Huntress is a MSP-channel while Armor is a Platform vendor.
Ontinue
Microsoft-native MXDR with 99.5% AI-automated incident resolution and Teams-based collaboration. Data stays in your own Sentinel instance, giving full portability if you leave. Microsoft-only, not suitable for multi-vendor stacks.
Ontinue and Armor are both require their own platform and both target Mid-market and Enterprise organizations.
Ontinue is a Microsoft-ecosystem while Armor is a Platform vendor.
Cyderes
Technology-agnostic MDR built on Google Chronicle with deep identity security integrations and three delivery models (client-managed through fully managed). Trade-off: opaque pricing, almost no public reviews, and a complex corporate history from multiple mergers.
Cyderes and Armor are both target Mid-market and Enterprise organizations and both cover 3 of the same surfaces.
Cyderes works with your existing tools (Armor requires its own platform).
GoSecure
Bundles endpoint, network, email, and AD identity detection in a single platform with published per-endpoint pricing. DHS CDM APL listing adds government credibility. Trade-off: almost no public reviews exist, and the platform-native architecture requires the Titan EDR agent despite 'open XDR' positioning.
GoSecure and Armor are both require their own platform and both target Mid-market and Enterprise organizations.
GoSecure is a Pure-play MDR while Armor is a Platform vendor.
Kroll
Kroll Responder's differentiator is depth of real-world IR experience: 3,000+ annual breach investigations feeding detection and response. This is a services firm with MDR, not an MDR vendor with services. Complete Response methodology, included $1M breach warranty, and direct escalation to IR/forensics teams set it apart. December 2025 CrowdStrike migration brings faster response but increases platform dependency.
Kroll and Armor are both target Mid-market and Enterprise organizations and both cover 3 of the same surfaces.
Kroll works with your existing tools (Armor requires its own platform).
Orange Cyberdefense
European regulatory accreditations and geographic SOC coverage that few MDR providers can match. Broad service catalog from a single vendor. Trade-off: no published detection metrics, no MITRE participation, and zero practitioner reviews anywhere online.
Orange Cyberdefense and Armor are both target Mid-market and Enterprise organizations and both cover 3 of the same surfaces.
Orange Cyberdefense works with your existing tools (Armor requires its own platform).
ReliaQuest
Strong fit for enterprises wanting to unify and automate across their existing multi-vendor security stack without ripping and replacing tools. The Agentic AI platform delivers fast detection and orchestration, but you pay premium pricing and lose the unified view if you leave.

ReliaQuest works with your existing tools (Armor requires its own platform).
Trustwave
Strongest compliance credentials in MDR (FedRAMP, PCI DSS QSA, StateRAMP) backed by SpiderLabs, a 1,000+ person offensive security team. The go-to for government buyers and heavily regulated industries. Ownership instability and a confusing product portfolio (MDR vs. MXDR vs. Co-Managed SOC) mean you need to be precise about what you are buying.
Trustwave and Armor are both target Mid-market and Enterprise organizations and both cover 3 of the same surfaces.
Trustwave works with your existing tools (Armor requires its own platform).
Expel
API-first, vendor-agnostic MDR with 160+ integrations and full transparency into every SOC action via Workbench. Ideal for tech-forward organizations that want to keep their existing security tools and add a managed detection layer. Trade-off: threat hunting and incident response are add-ons, not included in base pricing, and no breach warranty.
Expel and Armor are both target Mid-market and Enterprise organizations and both cover 3 of the same surfaces.
Expel works with your existing tools (Armor requires its own platform).
Red Canary
Vendor-agnostic MDR with 9 EDR platform integrations and detection-as-code methodology, the broadest EDR support in the MDR market with strong analyst validation (Forrester Leader, G2 #1 satisfaction). Post-Zscaler acquisition: integrations maintained and product quality intact, but elevated customer churn and declining mindshare (4.2% to 2.9%) suggest some buyers are reconsidering.
Red Canary and Armor are both target Mid-market and Enterprise organizations and both cover 3 of the same surfaces.
Red Canary works with your existing tools (Armor requires its own platform).
Arctic Wolf
The Concierge Security Team model is Arctic Wolf's core differentiator: a named team that knows your environment and provides proactive security reviews. Technology-agnostic design avoids vendor lock-in, and the $3M warranty is the industry's largest. The trade-off is limited data transparency, guided (not hands-on) remediation, no published detection benchmarks, and a 71% false alarm rate by their own reporting.
Like Armor, Arctic Wolf — both target Mid-market and Enterprise organizations.

Blackpoint Cyber
MSP-channel MDR with autonomous SOC response (self-reported 7-16 min MTTR) and patented network visualization. Trade-offs: MSP-only sales model, limited portal transparency, no approval controls, no MITRE validation.
Blackpoint Cyber and Armor are both require their own platform and both target Mid-market organizations.
Blackpoint Cyber is a MSP-channel while Armor is a Platform vendor.
Mandiant
Threat intelligence-driven MDR backed by 500+ intel analysts, frontline IR experience, and Google Cloud infrastructure. Best for enterprises facing sophisticated threats who need detection backed by the organization that publishes the industry's most-cited threat intelligence report (M-Trends). Premium pricing and separate IR retainer are the main trade-offs.
Mandiant and Armor are both target Mid-market and Enterprise organizations and both cover 3 of the same surfaces.
Mandiant works with your existing tools (Armor requires its own platform).
Proficio
The core differentiator is SIEM flexibility: Proficio works with your existing SIEM or hosts one for you, which avoids the rip-and-replace problem. They publish detection metrics, which is more transparent than most providers this size. Trade-off: automated response costs extra, peer reviews are scarce, and the small team may not suit large enterprises.
Like Armor, Proficio — both target Mid-market and Enterprise organizations.
Proficio works with your existing tools (Armor requires its own platform).
Secureworks
Open XDR MDR with broad integration, CTU threat intelligence (now Sophos X-Ops), strong MITRE results, and included unlimited remote IR. Post-Sophos acquisition: Taegis continues with active investment. Main risk is whether Sophos sustains enterprise Taegis investment long-term.
Secureworks and Armor are both target Mid-market and Enterprise organizations and both cover 3 of the same surfaces.
Secureworks works with your existing tools (Armor requires its own platform).
Todyl
SASE, EDR, SIEM, MXDR, SOAR, and GRC in a single agent with a dedicated DRAM per customer. Built for MSPs willing to commit to one vendor in exchange for eliminating tool sprawl. Trade-off: total platform lock-in and limited independent validation.
Todyl and Armor are both require their own platform and both target Mid-market organizations.
Todyl is a MSP-channel while Armor is a Platform vendor.
Binary Defense
Binary Defense's core differentiator is proactive threat hunting with an attacker's mindset, consistently earning the highest Forrester scores in that category. The open XDR approach works with your existing tools and emphasizes data portability. The trade-off is US-only SOC operations, no published detection metrics, and some reports of declining service quality as the company scales.
Binary Defense and Armor are both target Mid-market and Enterprise organizations and both cover 3 of the same surfaces.
Binary Defense works with your existing tools (Armor requires its own platform).
Critical Start
Technology-agnostic MDR with TBR deterministic alert auto-resolution, 100+ integrations, OT/ICS support, two-person response validation, and MITRE Engenuity participation (2022). Trade-off is fully opaque pricing, enterprise focus, no breach warranty, and no Slack integration.

Critical Start works with your existing tools (Armor requires its own platform).
Lumifi
Vendor-agnostic co-managed MDR that works with your existing EDR and keeps data in your environment. Three acquisitions since 2022 expanded the platform into SIEM and healthcare/government, but independent validation is minimal and public peer feedback is nearly nonexistent.
Lumifi and Armor are both target Mid-market organizations and both cover 3 of the same surfaces.
Lumifi works with your existing tools (Armor requires its own platform).
Deepwatch
SIEM-centric, vendor-agnostic MDR with patented DRS engine (98% FP reduction claim), dedicated Squad team per customer, and deep Splunk/Chronicle/Sentinel/Securonix expertise. Organizational instability (CEO change, 42% headcount cut, negative employee reviews) warrants explicit due diligence on service continuity.
Like Armor, Deepwatch — both target Mid-market and Enterprise organizations.
Deepwatch works with your existing tools (Armor requires its own platform).
eSentire
eSentire excels at active, hands-on response with contractual 15-minute containment guarantees.

eSentire works with your existing tools (Armor requires its own platform).
Truesec
Premier Nordic MDR with the largest Scandinavian SOC and deep IR background (120,000+ hours, vendor-stated). Unique MDR Black tier covers IR costs for breaches on monitored devices. Strong fit for Nordic enterprises wanting local expertise. Limited US presence and zero independent reviews make it hard to evaluate for North American buyers.
Truesec and Armor are both target Mid-market and Enterprise organizations and both cover 3 of the same surfaces.
Truesec works with your existing tools (Armor requires its own platform).
Ackcent Cybersecurity
Gartner-recognized European boutique MDR with native Spanish support and bring-your-own-EDR flexibility. Good fit if you want a smaller, relationship-driven provider in the Iberian or LATAM markets. Trade-off: almost nothing is publicly documented, so due diligence relies heavily on direct engagement.
Ackcent Cybersecurity and Armor are both target Mid-market and Enterprise organizations and both cover 3 of the same surfaces.
Ackcent Cybersecurity works with your existing tools (Armor requires its own platform).
Barracuda Networks
Purpose-built for the MSP channel with multi-tenant management, SentinelOne-powered endpoint security, and a 24/7 global SOC. Natural fit for MSPs serving SMB clients who need turnkey XDR. Less proven for direct enterprise buyers. Detection claims lack independent validation and security logs are not downloadable.
