Support Open Source

ISC is a not-for-profit organization. We do not have an endowment, and we are not funded by “the government.”

We employ full-time, professional software engineers to develop and maintain the code that you can download for free.

In the past, ISC accepted donations from companies to publish links to their websites. We no longer accept these types of donations.

We maintain our operations by selling annual software support contracts to organizations who want to ensure both the stability of their mission-critical Internet infrastructure and the survival of ISC’s open source software model.

THANK YOU for supporting open source.
