Email Security that works with what you have.

Easily integrate Zix solutions with your existing infrastructure and investments.


Compatibility Program

Here at Zix we know email security – and we also know all the other elements of your infrastructure need to work with our solutions. Our products are based on standards such as SMTP, and the Zix Compatibility Program ensures that Zix works with everything else in your IT environment. We have thousands of customers that have used Zix in diverse environments over 15 years, and we know that we can leverage your existing IT investments and quickly deploy Zix to provide email security.

Email Servers and Services

More than 15 years of experience and thousands of customers demonstrate that Zix solutions work with a wide variety of email servers and services.  SMTP interoperability and dedicated integration with leading providers ensure email is sent and received securely, regardless of which provider you are using. Zix solutions work with:

  • Microsoft Office365 & Outlook
  • Google G Suite & Gmail
  • Groupwise
  • IBM Notes
  • PostFix
  • SendMail
  • Zimbra
  • Webmail, inc. AOL & Yahoo

Secure Email Gateways

Organizations use secure email gateways (SEGs) to protect from spam and email based threats.  Zix can provide an SEG solution bundled with email encryption, but if you already have an SEG in place, Zix works with that too. Zix solutions work with SEGs from:

  • Barracuda
  • Cisco
  • Dell SonicWall
  • ForcePoint
  • Fortinet
  • Mimecast
  • Proofpoint
  • Sophos
  • Symantec
  • Trend Micro
  • Trustwave
  • Watchguard

Enterprise Data Loss Prevention

Organizations use enterprise data loss prevention (DLP) to prevent inadvertent or accidental exposure of sensitive information to unauthorized users. Zix Email Encryption includes DLP features to ensure that sensitive information in email is protected. Zix can also be used in conjunction with other DLP solutions to ensure that emails with sensitive information are protected by your enterprise policies, without requiring any extra work by users. Zix works with many enterprise DLP providers, including:

  • Digital Guardian
  • Fidelis Security
  • Forcepoint
  • Intel Security
  • Symantec

Enterprise Information Archiving

Archiving content is used by many organizations for compliance, risk management, governance and cost optimization. ZixArchive can assist with your organization with email retention, but if you have another archiving solution in place, Zix’s SMTP interoperability allows it to send email securely without impacting your existing solution. Zix email encryption solutions work with many information archiving solutions, including those from:

  • Commvault
  • Dell EMC
  • Global Relay
  • HPE
  • Mimecast
  • Proofpoint
  • Smarsh
  • Veritas

Network Security & Unified Threat Management

Network security is a given for all organizations, and Zix works with it, from firewalls to intrusion prevention systems. We know that for many organizations with limited IT resources and budget that Unified Threat Management (UTM) devices that combine enterprise firewall and intrusion prevention systems, as well as secure web and email gateway functionality, in a single appliance are a popular choice. Here at Zix, we work with network security and UTMs from:

  • Fortinet
  • Juniper Networks
  • Sophos
  • Watchguard
  • Barracuda Networks
  • Checkpoint Technologies
  • Cisco
  • Dell Sonicwall

Security Information & Event Management

Many organizations use security information and event management (SIEM) solutions to enhance their situational awareness by aggregating event data produced by security devices, network infrastructure, systems and applications. Zix allows administrators to automatically import encrypted email data logs into a syslog format for integration with SIEM solutions such as:

  • Alienvault
  • EMC (RSA)
  • Intel Security
  • HPE
  • IBM
  • LogRythm
  • Micro Focus
  • NetIQ
  • Splunk
  • Trustwave

Single Sign On

Authentication is an important component of email encryption. When email is delivered to a secure web portal, customers can use the native authentication of Zix or credentials they have already established with their customers. Zix secure web portals support Google and Microsoft OAUTH for customers that send encrypted emails to consumer email accounts, eliminating the need for users to register or remember another password. For organizations with a single sign on (SSO) solution, Zix secure web portals act as the SAML 2.0 service provider, and the SSO solution acts as the identity provider (IP). When users try to access the Zix secure web portal that has been configured for SSO, the user signs on to the IP and is then redirected back to the Zix secure web portal after being authenticated.

Zix also supports IP initiated SSO, where the user signs into the IP and then uses a custom link to access the secure web portal without being required to sign in. Zix will work with any SAML 2.0 IP, including:

  • Ping Identity
  • Okta
  • Oracle
  • SailPoint
  • CA Technologies
  • Dell Technologies
  • Entrust
  • IBM
  • Micro Focus
