CyberCheck360 Email Guard
by CyberCheck360
Real-time link protection and sandboxing, built into your Outlook inbox.
CyberCheck360 Email Guard for Outlook adds a powerful, post-delivery security layer directly inside your inbox, helping users safely engage with emails that bypass traditional email security gateways.
Designed to work independently or alongside your existing email security setup, Email Guard gives users real-time threat intelligence, clear security verdicts, and advanced link isolation so every email interaction is informed and safe.
Key Capabilities
Email Header Intelligence: Get deep visibility into the true source of every email. Email Guard analyses message headers to detect spoofing, sender anomalies, and authentication failures, helping users quickly spot deceptive messages that appear legitimate.
Real-Time Link Analysis: Links are evaluated at the moment of interaction using live threat intelligence. Users receive clear verdicts before they click, protecting against phishing URLs and weaponised links that activate after delivery.
Secure Link Isolation: Open suspicious links in a fully isolated, remote sandbox environment. Content executes away from your device and network, giving you zero exposure and full visibility.
User-Visible Security Verdicts: Email Guard surfaces actionable security insights directly inside Outlook, helping users understand risk rather than just react to it. No disruption to workflows. No security training required.
Why Email Guard?
Traditional email security focuses on blocking threats before they arrive. Email Guard activates at the moment that matters most, when a user is about to interact with an email.
Works seamlessly inside Outlook
Complements existing email gateways and Microsoft Defender deployments
Requires no changes to mail flow
