Zero trust email security applies the never trust, always verify principle to every email, sender, link, attachment and user interaction, regardless of whether the message appears to come from inside or outside the organization. It closes the internal email blind spot and BEC detection gaps that traditional perimeter-based email security leaves wide open. If you…
Managed email security is a service where a third-party provider deploys, monitors and actively manages email security technology on a client’s behalf. It delivers 24/7 threat detection, ongoing policy tuning and incident response without requiring the client to build in-house specialist staff.

Some attacks combine both. If you have just clicked on a phishing link, disconnect from the network immediately, close the…
Quishing is a cyberattack that embeds malicious URLs inside QR code images in emails to bypass email security scanning. What is quishing in email security precisely?
