Email Security & Anti-Phishing Indianapolis | Monon Technology Services

Email Security — Indianapolis

Your Inbox Is the Most Targeted Surface in Your Business.

Over 90% of cyberattacks start with an email. Phishing, impersonation, and business email compromise don't require sophisticated hacking — they just need one employee to click. We configure the technical controls that stop threats before they reach the inbox.

Attack Types

The Email Threats We Protect Against.

🎣

Phishing

Emails designed to trick users into revealing credentials, clicking malicious links, or downloading malware. Volume-based, highly automated.

🎯

Spear Phishing

Targeted phishing using personal or company-specific information — harder to detect, significantly higher success rate.

👔

Business Email Compromise

Attacker impersonates an executive or vendor to request wire transfers or credential changes. No malware — just social engineering.

🏢

Domain Impersonation

Sending emails from domains that look like yours — monontechnologyservices.com vs monon-technologyservices.com. Fools most people.

📎

Malicious Attachments

PDFs, Office docs, and ZIP files carrying malware that executes on open — often evading standard attachment scanning.

🔗

URL Manipulation

Links that appear legitimate but redirect through malicious infrastructure — including links that switch after delivery.

What We Configure

Technical Controls That Actually Stop Email Threats.

DMARC / DKIM / SPF Setup

Properly configured DNS records that prevent anyone from sending email that appears to be from your domain — eliminating spoofing at the source.

Microsoft Defender for Office 365

Safe Links, Safe Attachments, anti-phishing policies, and impersonation protection configured correctly — not left at default.

Spam & Phishing Filter Tuning

Aggressive phishing detection with allowlists calibrated so legitimate mail isn't blocked — balancing protection with deliverability.

External Email Tagging

Visual warning banners on all email originating outside your organization — a simple control that significantly reduces click-through rates.

Mailbox Audit Logging

Audit logging enabled on all mailboxes — essential for detecting compromised accounts and supporting incident investigation.

Compromised Account Response

Procedure for responding to a compromised mailbox — block, review sent items, reset credentials, assess blast radius.

Domain Protection

DMARC, DKIM, and SPF — What They Are and Why All Three Matter.

These three DNS records work together to authenticate your email and prevent impersonation. Most businesses have SPF set up incorrectly and DMARC missing entirely.

SPF

Sender Policy Framework

Declares which servers are authorized to send email on behalf of your domain. Prevents basic spoofing.

DKIM

DomainKeys Identified Mail

Adds a cryptographic signature to every outgoing email — recipients can verify the message wasn't altered in transit.

DMARC

Domain-Based Message Authentication

Ties SPF and DKIM together and tells receiving servers what to do with unauthenticated mail — quarantine or reject. Also provides reporting.

The Human Layer: Security Awareness

Technical controls stop the majority of threats. But some will still reach users — and training determines what happens next. We help clients implement security awareness training alongside technical controls.
