Open Source Technology Improvement Fund
The Open Source Technology Improvement Fund is a corporate non-profit dedicated to securing open source apps that we all depend on. Securing software isn’t easy, and we know what it takes to succeed. By facilitating security audits and reviews, OSTIF makes it easy for projects to significantly improve security.

Support the OSTIF Mission
Open-source projects keep today’s Internet infrastructure afloat. They are critical for the operation of every webserver, every browser, and every banking platform. And they are cared for by a surprisingly small group of people with a limited amount of time. Without dedicated security experts, these projects often don’t get the attention they require.
We can do it with help from supporters like you.
