Defensibility in Action

In 2025, MSPs aren’t just managing endpoints, we’re managing confidence.Our clients expect more than alerts and antivirus, they expect proof that their security stack works, holds up under scrutiny, and aligns with business risk.

At CommArc, we’ve built our layered defence strategy around multiple pillars some of these are:

Microsoft Defender for Endpoint for native protection and telemetry

Huntress for persistent threat detection and rapid response

NinjaOne for endpoint visibility, automation, and documentation discipline

Together, they form a defensible, auditable, and scalable security posture.

Microsoft Defender for Endpoint

Strengths:

Deep integration with Microsoft 365

Real-time threat analytics and behavioural detection

Rich telemetry for SOC and audit teams

MSP Value:

We configure Defender to align with client-specific risk profiles, ensuring alerts are tuned and escalation paths are documented. It’s our foundation for visibility and compliance.

Huntress

Strengths:

Detects footholds and persistence mechanisms missed by traditional AV

Human-led threat hunting and incident response

Lightweight agent, fast deployment

MSP Value:

Huntress is another layer, focused on what Defender might miss.It’s not just reactive, it’s proactive assurance.

NinjaOne

Strengths:

Unified endpoint management and automation

Custom scripting, patching, and alerting

Centralised documentation and reporting

MSP Value:

NinjaOne is part of our operational backbone. We use it to version control our configurations, automate patch hygiene, and generate audit-traceable reports. It’s how we turn technical controls into business clarity.

Clients don’t just want to know they’re protected, they want to know how.As MSPs, our job is to turn layered security into a defensible narrative. That means testing, documenting, and communicating with precision.

Because when the audit comes, or the breach hits, the best answer isn’t“We had tools.”

It’s:“Here’s what we knew. Here’s what we did. And here’s the proof.”
