Zix Corporation was a prominent provider of SaaS-based email encryption, email data loss prevention (DLP), advanced threat protection, and email archiving solutions. Founded in 1983 and headquartered in Dallas, Texas, Zix served thousands of customers across various industries, including healthcare, finance, and government, helping them meet compliance requirements (like HIPAA and GDPR) and secure sensitive communications. In December 2021, Zix Corporation was acquired by OpenText for $860 million. Its technologies and services have since been integrated into OpenText's security and information management offerings, particularly strengthening OpenText's capabilities in cyber resilience for small and medium-sized businesses (SMBs) and enterprises.
The Dallas headquarters housed Zix's executive leadership, administrative functions, sales, marketing, research and development, and customer support operations.
Located in a modern office building in the Uptown Dallas area, the headquarters likely featured contemporary office amenities, collaborative workspaces, and secure infrastructure appropriate for a cybersecurity company.
Zix was known for a culture focused on innovation in security, customer trust, and compliance. The environment likely encouraged collaboration and expertise in data protection technologies. Post-acquisition, employees and functions have been integrated into OpenText's broader corporate culture.
The Dallas headquarters was central to Zix's operations and growth as a specialized provider of email security solutions before it became a strategic asset for OpenText's expansion in the security market.
Prior to its acquisition, Zix Corporation had a strong presence in North America and parts of Europe, with data centers strategically located to serve its customer base. Now, as part of OpenText, Zix's former solutions are supported and delivered through OpenText's extensive global infrastructure. This includes a worldwide network of sales offices, support centers, R&D facilities, and data centers across the Americas, EMEA (Europe, Middle East, Africa), and APAC (Asia-Pacific) regions. OpenText globally supports functions like cybersecurity R&D, sales and marketing, customer support, cloud operations, and professional services.
