Email Security Services: How Attacks Work and How We Stop Them

Over 90% of cyberattacks start with a single email. One click on a fake invoice or spoofed login page can compromise your entire organization. Standard spam filters miss the targeted, sophisticated attacks that are designed to look exactly like messages from your bank, your boss, or your vendor. Our email security services stop phishing, malware, and business email compromise before they reach your inbox – using AI-powered filtering, link scanning, and sender verification.

01 — Mass Threat

Phishing

Mass-sent fake emails mimicking trusted senders — banks, Microsoft, DocuSign — designed to steal credentials or install malware. Even one click can compromise your entire network.

02 — Targeted

Spear Phishing

Targeted attacks using research on your company, employees, vendors, and org chart. These emails look completely legitimate and are engineered to bypass standard spam filters.

03 — Financial Fraud

Business Email Compromise

The attacker impersonates your CEO or vendor to redirect wire transfers or obtain sensitive data. No malware involved — just social engineering. Average loss: $125,000 per incident.

Our Email Security Stack

Six Layers That Stop Threats Cold

We build a defense-in-depth email architecture so no single point of failure can compromise your business.

Advanced Spam Filtering

Multi-layer filtering catches malicious emails before they reach inboxes — with near-zero false positives for legitimate business mail.

Anti-Phishing AI

Machine learning models detect novel phishing tactics in real time — including zero-day attacks that signature-based filters miss entirely.

DMARC / DKIM / SPF Setup

Domain authentication that prevents spoofing of your company email domain — blocking attackers from impersonating your brand.

Link & Attachment Scanning

Every link and attachment is checked before delivery. URLs are rewritten and scanned at click time — catching threats that appear after sending.

Email Encryption

TLS encryption in transit plus optional S/MIME for sensitive communications — ensuring confidential data never travels in plaintext.

Security Awareness Training

Monthly simulated phishing tests and micro-training for your team. Clickers are automatically enrolled in brief modules — building a human firewall.

Highest-Risk Threat

Business Email Compromise Protection

BEC is the #1 financial email threat facing small businesses — and it requires more than a spam filter to stop.

Why BEC Is Different — and How We Stop It

Business Email Compromise uses no malware — just deception. An attacker impersonates your CEO or vendor via a lookalike domain and requests a wire transfer or sensitive data. Standard spam filters miss these attacks entirely because the email often looks legitimate.

We configure domain authentication (DMARC, DKIM, SPF) that blocks spoofed emails from ever reaching inboxes. We set up impersonation alerts so you know immediately when someone tries to pose as your executive team. And we train your staff on the one verification step that stops every BEC attempt: calling back on a known number.
