CyberCheck360 Email Guard

CyberCheck360 Email Guard is a post-delivery phishing and ransomware protection add-in for Outlook. It adds a real-time security layer inside the inbox, giving users protection against phishing links, malicious attachments, and ransomware delivered via email even when threats bypass your existing email gateway or Microsoft Defender.

Email Guard works independently or alongside your current email security stack, giving users real-time threat intelligence, clear security signals, and isolated link and attachment handling so every email interaction stays safe from phishing, malware, and ransomware payloads.

Key Capabilities

Email Header Intelligence (Anti-Spoofing & BEC Protection): 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 spot business email compromise (BEC) attempts and deceptive messages that appear legitimate.

Real-Time Phishing Link Analysis: Links are evaluated at the moment of interaction using live threat intelligence. Users get a clear security signal before they click, protecting against phishing URLs and weaponised links that activate after delivery, when traditional scanning has already passed them through.

Isolated Link & Attachment Sandbox (Ransomware Protection): Open suspicious links and attachments inside a fully isolated, remote sandbox environment. Content runs away from the user's device and network, so ransomware payloads, malicious macros, and drive-by downloads never reach the endpoint. Zero exposure. Full visibility.

User-Visible Security Signals: Email Guard surfaces actionable security insights directly inside Outlook, helping users understand risk rather than react to it after the fact. No workflow disruption. No security training required.

Why Email Guard?

Traditional email security stops at delivery. Email Guard activates at the moment that matters most: when a user is about to open a link or attachment. This makes it an effective second layer of phishing protection and ransomware protection for organisations that already run a secure email gateway or Microsoft 365 Defender, and a strong standalone option for those that don't.
