Security and trust at Ossus

Intelligence for cultural institutions.

Ossus builds intelligence systems for libraries and cultural institutions. Cultural institutions hold public trust: they serve students, researchers, families, and communities, often with sensitive information about what people read, study, and wonder.

We design Ossus with that responsibility in mind. Our systems are built to help institutions understand and manage their collections without compromising patron privacy.
