Tehama (/təˈheɪmə/ tə-HAY-mə) is a Canadian Software as a Service (SaaS) company headquartered in Ottawa, Ontario, that provides a virtual, cloud-based, Desktop-as-a-Service (DaaS) platform for the secure exchange of work over the internet, allowing organizations to securely manage remote workers, third-party vendors, and freelancers, and integrate them into their working environments.

[4] Tehama began as a suite of virtual desktop, zero-trust network access, auditable secret and file sharing and workflow-automation technologies enabling secure, remote Internet-based work amongst the global workforce and clientele of Pythian, an IT services company founded in 1997.

Financing for this venture was provided by the New York-based private equity firm Mill Point Capital, which thereby gained a majority stake in Pythian.

[1] As one of Tehama's core services facilitates remote work, the company saw a notable upswing in interest in March 2020 during the COVID-19 crisis, with a 35-fold increase in inquiries from the prior month.

[8][9] In July 2020, Tehama conducted the Digital by Default Summit, an online virtual conference on the subject of remote work, with particular focus on its greater adoption in the wake of the COVID-19 crisis.
