365 Security Assessment
Microsoft 365 + Azure security audit platform. 24,000+ rules across Entra, Exchange, SharePoint, Teams, Defender, and Azure. 14-minute first finding. Built by a 4× Microsoft Solutions Partner.
Strengths
- Deepest M365/Entra/Exchange/SharePoint/Teams coverage in the category
- 14-day free trial — no credit card, no agents, read-only by design
- 10 compliance frameworks mapped (HIPAA, CMMC, PCI-DSS, SOC 2, ISO 27001, FedRAMP, GDPR, HITRUST, NIST 800-53, CIS M365)
Weaknesses
- Cloud workload protection (containers, K8s, IaaS VMs) is limited compared to pure CNAPP tools
- Not built for non-Microsoft SaaS coverage at depth
Who it's for: CISOs, IT directors, and MSPs at M365/Azure-heavy organizations who need audit depth, not breadth.
Pricing tier: Free tier · paid mid-market
Huntress
Huntress is a human-led managed EDR and Microsoft 365 ITDR platform built for MSPs serving SMBs. Its 24/7 SOC triages alerts so lean IT teams don't have to. Strong on persistence/foothold detection but light on config-drift audit.
Strengths
- 24/7 human SOC included in price
- Strong M365 ITDR for account takeover
- MSP-friendly multi-tenant console
Weaknesses
- No tenant-wide config audit or CIS/NIST scoring
- Reactive detection, not proactive posture
Who it's for: MSPs and SMBs who want managed detection, not a DIY audit platform.
Pricing tier: Per-seat MSP/SMB
Check Point Harmony Email & Collaboration
Formerly Avanan, now Check Point Harmony Email. API-integrated phishing, BEC, and malware protection that sits behind native M365 defenses. Excellent at email threat detection but does not audit tenant configuration or identity posture.
Strengths
- Best-in-class phishing/BEC catch rate
- Deploys in minutes via Graph API
- Covers Teams, OneDrive, SharePoint
Weaknesses
- Email-only - no endpoint, no config audit
- Overlaps with Defender for O365 P1/P2
Who it's for: Orgs whose biggest pain is phishing slipping past EOP.
Pricing tier: Per-seat SMB/Mid-market
Microsoft Defender for Business
Microsoft's SMB-tier endpoint protection, included with M365 Business Premium. Solid EDR with native Defender XDR integration, but exposes raw telemetry rather than audit-ready reports or compliance mappings.
Strengths
- Included in M365 BP - no extra cost
- Native Intune + Conditional Access integration
- Auto-investigation and remediation
Weaknesses
- Requires expertise to configure correctly
- No M365 tenant audit or compliance reporting
Who it's for: SMBs already on M365 BP who want endpoint coverage without a new vendor.
Pricing tier: Bundled (in M365 BP)
SentinelOne Singularity
Enterprise-grade autonomous endpoint and XDR platform with strong ransomware rollback. Built for security teams that want deep telemetry and customization - heavier and pricier than typical SMB EDR.
Strengths
- Industry-leading ransomware rollback
- Strong MITRE ATT&CK evaluation results
- Extensible XDR across cloud and identity
Weaknesses
- Cost and complexity exceed most SMBs
- No M365 configuration audit module
Who it's for: Mid-market with a SOC or MDR partner needing deep EDR.
Pricing tier: Sales-led
CrowdStrike Falcon Go
CrowdStrike's stripped-down SMB SKU bringing Falcon's threat intel and EDR to small businesses. Excellent endpoint protection, but no identity posture, no M365 config audit, and you outgrow Falcon Go at ~100 seats.
Strengths
- Same detection engine as enterprise Falcon
- Lightweight cloud-native agent
- Strong threat intel feed
Weaknesses
- Endpoint-only - no M365 or identity audit
- Forced upgrade path as you scale
Who it's for: Under-100-seat SMBs wanting brand-name EDR.
Pricing tier: Per-seat SMB
ESET Protect
Long-standing AV/EPP vendor with modular cloud console covering endpoint, mail, and full-disk encryption. Reliable and low-overhead, but lacks modern XDR depth and provides no M365 tenant audit.
Strengths
- Very low system impact
- Modular pricing - pay for what you need
- Mature multi-tenant MSP console
Weaknesses
- EDR/XDR less mature than peers
- No M365 config or identity assessment
Who it's for: Cost-conscious SMBs wanting solid AV plus optional add-ons.
Pricing tier: Per-seat SMB/Mid-market
Sophos Central
Sophos Central bundles endpoint, server, email, and firewall under one console, with optional 24/7 MDR. Strong for shops running Sophos hardware, but M365 coverage is shallow and there's no tenant audit.
Strengths
- Synchronized Security across endpoint+firewall
- Mature MDR offering
- Single pane for hybrid stacks
Weaknesses
- Best value only if you use Sophos firewalls
- Limited M365 posture visibility
Who it's for: SMBs already standardized on Sophos networking gear.
Pricing tier: Per-seat SMB/Mid-market
Trend Micro Worry-Free
Trend Micro's SMB suite covering endpoint, email, and basic cloud app security in one console. Easy to deploy and manage, but detection depth and M365 audit coverage trail modern XDR platforms.
Strengths
- Simple deployment, low admin overhead
- Bundled email + endpoint
- Strong global threat intel
Weaknesses
- Dated UX and reporting
- No M365 configuration audit
Who it's for: Very small businesses wanting one vendor for endpoint and email.
Pricing tier: Per-seat SMB
Microsoft 365 Business Premium (native)
Not a third-party product - the security stack already included with M365 Business Premium: Defender for Business, Conditional Access, Intune, and Defender for Office 365 P1. Powerful if configured correctly, but Microsoft ships defaults that leave most tenants exposed.
Strengths
- Already paid for in M365 BP licensing
- Native integration across identity, email, endpoint
- Conditional Access + Intune included
Weaknesses
- Configuration depth requires real expertise
- No audit reports, no compliance mapping, no posture scoring
Who it's for: SMBs on M365 BP who need help configuring what they already own - which is exactly where we fit.
Pricing tier: Bundled in M365 BP
