Secure Any Email System

Use Lastline Defender to improve cloud email security and
customer-managed email.

Deploy Lastline Defender as an additional layer of defense for cloud email as well as customer-managed email systems. Our technology protects your users from advanced email security threats that are engineered to defeat other tools – attacks including spear phishing, ransomware, cryptomining, credential stealers, business email compromise (BEC), social engineering, and other email-based attacks.

Lastline Defender improves Microsoft Office 365 email security, Gmail security, and also protects customer-managed email systems against threats that bypass those applications’ limited security controls. Lastline’s complementary layer of protection doesn’t add significant cost or complexity to your network.

  • Cloud email systems cannot stop advanced threats. While native Gmail and Office 365 eMail security can block spam and some rudimentary threats, they cannot detect and block advanced threats.
  • Traditional and “next-generation” email security tools leave your email systems and data at risk because bad actors continue to develop new techniques such as keyloggers, spear phishing, and fileless malware that bypass Secure Email Gateways (SEGs).
The Lastline architecture delivers maximum protection while giving you deployment flexibility and low TCO.

Flexible Deployment Options

Lastline Defender for Email complements your SEG and MTA (Mail Transport Agent) systems. You can choose among three  deployment options to passively monitor or actively block malicious content for complete email security.

Don’t fall victim to another business email compromise, ransomware, phishing, or any other email-based attack. Learn more about how Lastline Defender can secure both your customer-managed email and your cloud-based email system.
