Email & Collaboration
Secure, productive workspaces with Microsoft 365 and Google Workspace. Hardened email, not just hosted email.
Email Is Still Your Most Attacked Surface
91% of cyberattacks start with a phishing email. Yet most organizations run default email configurations with no advanced threat protection, no DMARC enforcement, and no DLP policies. Your email isn't just a communication tool — it's the front door to your organization. And right now, it's probably unlocked.

Managed Email vs. Default Configuration
Most organizations buy Microsoft 365 licenses and run the default configuration. That means no advanced threat protection, no DMARC, no DLP, and no email authentication. It's like buying a car with airbags and never turning them on. CMTG configures email security the way it should have been from the start.

Frequently Asked Questions
We already have Microsoft 365. Why do we need help?
Having M365 licenses doesn't mean they're configured correctly. Most organizations run default settings with no advanced threat protection, no DMARC, and no DLP. Our audit typically finds 15-20 critical security gaps in default M365 deployments.
What is DMARC and why does it matter?
DMARC prevents attackers from sending emails that appear to come from your domain. Without it, anyone can spoof your email addresses to phish your clients, vendors, or employees. We implement DMARC at p=reject — the strongest enforcement level — to fully protect your domain.
Can you migrate us from Google Workspace to Microsoft 365?
Yes, and vice versa. We handle full migrations including email, calendar, contacts, Drive/OneDrive files, and shared resources. Migrations are staged to minimize disruption, with both systems running in parallel during the transition period.
How do you prevent sensitive data from being emailed externally?
Through DLP (Data Loss Prevention) policies that scan outbound email for sensitive content — SSNs, credit card numbers, health information, or custom patterns. Matched content is blocked, quarantined for review, or encrypted automatically based on your policy.
Do you manage Teams and SharePoint too?
Yes. Our email & collaboration management covers the entire M365 suite — Exchange Online, Teams, SharePoint, OneDrive, and associated security features. We configure team structures, sharing policies, guest access controls, and governance for the complete collaboration platform.
