Stichting Prisma

Stichting Prisma is a Dutch care organization in Noord-Brabant supporting people with intellectual and physical disabilities across multiple locations, including Landpark Assisië in Biezenmortel. Its service lines span Begeleid wonen (supported living), Tijdelijk verblijf (respite and temporary residential stay), Dagbesteding (day activities), Begeleid werken (supported employment), and Hulp aan kinderen en gezinnen (support for children and families). The stated mission is to enable clients to live as normally as possible despite their limitations, delivered through multidisciplinary teams of doctors, nurses, and support workers (begeleiders).

The relevant surface for security work is digital: MijnPrisma, a client portal where clients view their appointments and follow their own care process, and the underlying care coordination systems. That places sensitive care data, appointment records, and client-facing access flows in scope - a threat model where unauthorized access means exposure of highly personal disability and health information belonging to a vulnerable population. The technical domains in play are the client portal / digital care platform and the care coordination systems that feed it.

Stichting Prisma has held ANBI status (algemeen nut beogende instelling, the Dutch public benefit designation) since 2008, so it operates as a non-profit with the reporting obligations that come with it. The organization emphasizes personal, qualitative care and positions MijnPrisma as a tool for transparency and client empowerment - clients get direct visibility into their own care trajectory, which makes the portal's access controls, session handling, and data integrity a first-order concern rather than an IT afterthought.
