  • Email Threat Protection

    ZixProtect delivers 99.5% accuracy in detecting spam, viruses, phishing, zero-day malware, and ransomware. ZixProtect’s multi-layer filtering engine provides the highest level of accuracy that reduces both false negatives (bad emails getting in) and false positives (good emails kept out). This reduces the time your IT team has to spend managing the system and improves business communication flow.

  • Multi-layer filtering

    ZixProtect’s multi-layer filtering provides accurate threat protection by putting more emphasis on the email content instead of the source of the email. ZixProtect first looks for IP addresses and URLs that are known to be malicious. Then, filters examine email content, looking for targeted phrases and campaign patterns that only occur in malicious email. Immediately after, ZixProtect scans for known and zero-hour malware. If emails pass through but still seem suspicious, they can be re-filtered after a short time delay while our live threat analysts review new content and refine filters. These robust filters are combined with automated traffic analysis, sophisticated machine learning, and 24/7/365 live threat analysts to create a system that accurately identifies and protects against even the latest zero-hour attacks

  • Email Encryption

    ZixProtect email encryption automatically determines the most efficient way to securely deliver sensitive emails using our patented Best Method of Delivery. Through the Best Method of Delivery, encrypted emails are delivered to anyone, anywhere and often transparently. As part of the Best Method of Delivery, Zix offers the industry’s only bi-directional transparent email encryption, enabling senders and recipients to exchange encrypted email without any extra steps. When you send an encrypted email to another Zix customer, the message and replies are encrypted transparently, so that not even a password is needed. ZixProtect also offers a secure way to try sending using Transport Layer Security (TLS) without being susceptible to a man-in-the-middle attack. When sending to recipients who do not have email encryption capabilities, Zix offers a secure portal that makes receiving an encrypted email easy, even on a mobile device. The secure portal can be branded and configured to meet your business needs and can be integrated into you corporate website.

  • Email Data Loss Prevention

    ZixProtect provides robust filtering technology that enables you to define and manage policy rules for protecting sensitive email content and ensuring compliance. Pre-defined filters are available for healthcare, financial services, state privacy, education and more. Based on the email content, policies can be defined to determine if the email should be blocked, routed, quarantined or encrypted.
