Security Is Too Expensive — When It’s Done the Old Way

We use the Microsoft tools you already own, operate with US-based Tier 1–3 SOC analysts, and give you options: we can integrate with your existing workflows or fully manage your security stack.

 

Too Many Tools, Too Little ROI

Defender, Intune, Sentinel — but they’re not operationalized, leaving gaps.

Hiring Isn't the Answer

SOC staffing is expensive, hard to retain, and nearly impossible for lean teams.

ThreatDefender is the Shortcut

Get faster outcomes, deeper insights, and 24×7 coverage — for less.

In over 90% of ransomware incidents, unmanaged devices were the entry point. ThreatDefender extends your visibility to reduce risk before it spreads.

FAQ

Do you have questions regarding how ThreatDefender MXDR works, on what you need to get started, or how it compares to traditional MDR? You're not alone.

Do I need to buy new Microsoft licenses to use ThreatDefender?

No. ThreatDefender is built to work with what you already own– especially Microsoft 365 E3 or E5. We help you activate the full value of your security tools like Sentinel, Defender, Intune, and Entra ID.

Most MDR providers use third-party tools and require additional licensing. ThreatDefender is Microsoft-native, meaning it uses your existing environment and focuses on configuration, integration, and 24/7 response, with no tool sprawl or duplication.

We triage and investigate every alert using Microsoft Sentinel and SOAR automations — but we don’t just pass alerts along. Our SOC analysts resolve low-risk issues independently and only escalate when necessary.

Over time, we develop a deep understanding of your environment so we can recognize normal vs. abnormal behavior, reduce noise, and respond more efficiently. When escalation is needed, we deliver clear, contextual guidance — acting as a true extension of your team.

Can ThreatDefender detect BEC or lateral movement?

Yes. We monitor indicators across email, identity, and endpoint activity using Microsoft Defender and Entra ID. That includes inbox rule abuse, suspicious logins, and privilege escalations — common in BEC and lateral movement scenarios.

We start with a technical discovery session, connect your Microsoft tenant via Lighthouse, configure Sentinel and Defender, and begin 24/7 monitoring — typically in under 30 days.

ThreatDefender is designed to be cost-effective for lean teams. You don’t need to hire more staff or pay for duplicate software, and many clients spend less than the cost of one full-time SOC analyst.
