Email Security for Your Business

Email is where most cyberattacks on small and mid-sized businesses begin. Phishing attempts, impersonation scams, and business email compromise can put your finances, your data, and your clients’ trust at risk. MRTECH Computer Support helps businesses secure their email systems so that a single suspicious message doesn’t turn into a costly incident.

Protecting Against Phishing & Impersonation

Cybercriminals often impersonate trusted contacts, vendors, or even coworkers to trick employees into clicking malicious links, sending payments, or sharing sensitive information. MRTECH helps put safeguards in place to catch these attempts before they cause damage.

What Our Email Security Support Includes

• Domain Authentication Setup: Configuring SPF, DKIM, and DMARC records so your domain is harder to spoof — the same protections we check in our free Domain & Email Audit.
• Phishing & Threat Filtering: Reducing the volume of malicious messages that reach your team’s inbox.
• Microsoft 365 & Google Workspace Security: Hardened email security settings for the platforms you already use — see Microsoft 365 and Google Workspace.
• Ongoing Monitoring: Continued oversight as part of our broader cybersecurity and Managed IT Services.

Frequently Asked Questions

What is the difference between Email Security and the Domain & Email Audit tool?

The Domain & Email Audit is a free, one-time check of your current domain and email authentication setup. Email Security is the ongoing service MRTECH provides to configure, monitor, and maintain that protection over time.

How does email security protect against invoice or payment fraud?

Proper domain authentication (SPF, DKIM, DMARC) combined with phishing filtering makes it much harder for criminals to impersonate your business or your vendors in email-based payment scams.

Does email security cover Microsoft 365 and Google Workspace?

Yes. MRTECH configures and manages email security settings for both platforms as part of this service.
