Fenestrae

Cybersecurity · The Hague, Netherlands · Founded 1990

Global provider of innovative solutions that help organizations improve agility and reduce costs MoreLess

In 1990, a company named Fenestrae was founded in The Hague, Netherlands, by Wim De Koning. The business was built on the idea of digitizing paper-based workflows, a significant challenge for enterprises at the time. Their key product, Faxination, became a robust solution for companies to manage, send, and receive faxes directly from their email systems and business applications. This integration with major platforms like Microsoft Exchange was a key part of their playbook, allowing them to serve large corporate clients in regulated industries such as finance and healthcare that relied on secure and compliant document exchange. For years, Fenestrae operated as a specialist in this niche, evolving its products from on-premise servers to cloud-based solutions to meet modern IT demands. The company's focus remained on providing a secure and reliable bridge between legacy paper-based processes and the digital world. This journey of steady, focused growth culminated in a significant event. On October 25, 2022, the Dutch software company was acquired by Dura Software, a San Antonio-based firm specializing in buying and operating niche software businesses. This marked a new chapter for Fenestrae, bringing it into a larger portfolio while validating its long-standing mission to streamline enterprise communications.
