Rise in Phishing Since 2022
Your Inbox Is the #1 Attack Vector
Every day, your employees receive hundreds of emails. Mixed in with legitimate messages are sophisticated phishing attempts, malicious attachments, weaponised links, and business email compromise attacks designed to steal credentials, deploy malware, or trick someone into wiring money to a fraudster.
Native email security in Microsoft 365 and Google Workspace catches the obvious spam — but advanced attacks bypass these filters consistently. Spear phishing targeting your CEO, zero-day malware in PDFs, lookalike domains impersonating vendors — these need dedicated email security that goes beyond built-in protection.
Intello deploys, configures, and manages enterprise email security solutions that stop threats before they reach the inbox — and catch anything that slips through.

How Email Security Works
Multi-layered protection at every stage
Gateway Filtering
Incoming email scanned at the gateway — spam, known malware, and blacklisted senders blocked before reaching your server.
Advanced Analysis
AI and ML analyse content, headers, sender reputation, and behaviour patterns detecting sophisticated phishing and BEC attempts.
Sandbox Detonation
Suspicious attachments and URLs detonated in isolated sandboxes — catching zero-day malware and weaponised documents.
Post-Delivery Protection
Emails already in inboxes continuously monitored — malicious URLs retracted and threats remediated even after delivery.
