Email Security
Advanced filtering for phishing, malware, and BEC attacks.
Email is still the number one entry point for cyberattacks. Phishing, malware, business email compromise (BEC), credential theft, and ransomware delivery all start with an email that someone clicks. Default email security from Microsoft 365 and Google Workspace catches the obvious stuff. Advanced threat protection layers catch what the defaults miss (and that is where most of the actual damage happens).
MCR Business Tech Solutions deploys advanced email security for businesses across Pennsylvania, Ohio, West Virginia, and New York. Microsoft 365 ATP for Microsoft tenants. Proofpoint, Mimecast, or Avanan for Google Workspace and complex environments. The result is roughly 95% reduction in dangerous email volume reaching the inbox, plus the audit documentation needed for compliance.
BEC defense is where modern email security earns its keep. The CEO-asking-for-gift-cards scam. The wire-transfer-redirect scam. The vendor-bank-account-change scam. These attacks do not contain malware (they bypass antivirus entirely) and the attacker often impersonates someone the recipient trusts. Header analysis, display-name lookup, lookalike-domain detection, and behavioral analysis catch them. Without these layers, BEC attacks succeed at painful rates.
DMARC, SPF, and DKIM are the outbound side. Your legitimate email reaches inboxes (not spam folders), and impersonators cannot send mail as your domain. Most small businesses have these configured wrong (or not at all), which means inbox providers do not trust them, and attackers can impersonate them with nothing stopping it. We configure these properly and review the quarterly DMARC reports for ongoing tuning.
User training is the last layer. Quarterly phishing simulation campaigns plus just-in-time training when users click. Makes the team part of the defense rather than just the attack surface. Click rates typically drop 60-80% within 12 months of consistent training.
What's included
Advanced Threat Protection
Inbound mail filtered through multiple layers: reputation analysis, attachment sandboxing, URL rewriting, and AI-based phishing detection. Catches what the default filters miss.
Business Email Compromise Defense
Specific protection for impersonation attacks (the CEO-asking-for-gift-cards scam, the wire-transfer-redirect scam). Header analysis, display-name lookup, and lookalike-domain detection.
DMARC, SPF, DKIM Configuration
Outbound authentication so your legitimate email reaches inboxes (not spam folders) and impersonators cannot send mail as your domain. Quarterly DMARC reports reviewed for ongoing tuning.
URL Rewriting
Links inside emails are rewritten through the security platform. Even if a user clicks, the destination is checked at click-time (not just at delivery-time), catching delayed-payload attacks.
Attachment Sandboxing
Attachments are detonated in an isolated sandbox before delivery. Malicious behavior is detected and the email is blocked before it reaches the user.
User Training
Quarterly phishing simulation campaigns plus targeted training when users click. Makes the team part of the defense rather than just the attack surface.
Why businesses choose MCR
Advanced Threat Protection
Catches what default Microsoft and Google filters miss. URL rewriting, attachment sandboxing, AI-based phishing detection, BEC defense.
DMARC Done Right
Most small businesses have DMARC misconfigured or absent. We configure it properly and review the reports quarterly for ongoing tuning.
BEC Defense
Specific protection against impersonation attacks. The kind of email that does not contain malware but causes the most damage.
User Training
Quarterly phishing simulations plus just-in-time training when users click. The team becomes part of the defense, not just the attack surface.
Getting started
Audit Current Posture
Review existing email security (Microsoft 365 default, Google Workspace, third-party gateways), DMARC/SPF/DKIM configuration, and recent threat history.
Deploy ATP & Authentication
Advanced threat protection layered on top of existing tenant security. DMARC/SPF/DKIM configured and tested. Outbound mail flow validated.
Train & Tune
Phishing simulation program launched, quarterly campaigns scheduled. DMARC reports reviewed monthly for tuning. Threat patterns surfaced and shared with the team.
Frequently asked questions
Microsoft 365 already has email security. Do I need more?
Microsoft's default protection catches common threats. Advanced ATP layers catch what the default misses (especially BEC and zero-day phishing). For small businesses, ATP plus user training is usually the right balance of protection and cost.
What is DMARC and why does it matter?
DMARC tells inbox providers what to do with email that claims to be from your domain but fails authentication. Without DMARC, attackers can spoof your domain to send phishing to your customers. With DMARC enforced, inbox providers reject spoofed mail outright.
How effective is phishing simulation training?
Quarterly simulation campaigns typically reduce click rates by 60-80% within 12 months. Users who click simulations get just-in-time training; the team learns by doing rather than by watching a generic video once a year.
Does this work with Google Workspace too?
Yes. We deploy Microsoft 365 ATP for Microsoft tenants and equivalent third-party platforms (Proofpoint, Mimecast, Avanan) for Google Workspace tenants.
