Email Security

Fortify your email protection.

Win the battle against email threats

Your company email faces a constant bombardment of phishing, malware, viruses, and other threats. It’s an ongoing battle that if left unchecked can compromise your sensitive data, increase IT workloads, and damage your company’s reputation. AT&T Secure Email Gateway can be your secret weapon.

Help protect your email, help protect your company

Our Secure Email Gateway is designed to block email threats before they reach your network. It helps secure your email data, stop spam, guard against "click-this-link" malware attacks, and other inbound threats while also helping to prevent inappropriate or sensitive content from going out.
