Clear agreements and controls
Target group, method, files, questionnaire, schedule and responsibilities are agreed in advance.
Quality & security
DESAN combines certified research processes, information security, Security & Privacy by Design and fully managed proprietary infrastructure.
Layered control
Research quality
Good research data is not created only during analysis. Quality is built from research design and questionnaire development through fieldwork, data validation and delivery.
Target group, method, files, questionnaire, schedule and responsibilities are agreed in advance.
Routing, validations, quotas, invitations and reports are tested before fieldwork starts.
Response, distribution, deviations and quality signals are monitored during delivery.
Data is validated and delivered according to agreed specifications, including reporting where required.
Protection of research data
Research files and personal data are exchanged through a secure transfer process. Receipt confirmation shows when files have been received safely. Within IT5 and custom applications, access is limited to users who need it.
By design
IT5 and custom applications are designed from the outset with attention to security, privacy, access management and auditable processing.
Own infrastructure
DESAN’s core infrastructure runs on proprietary systems in two Dutch data centres. Dedicated fibre connections link the office and data centres and support redundancy, continuity and direct technical control.
Testing and continuity
Technical measures only have value when their operation and follow-up are also verified.
Applications and office and data-centre networks are periodically assessed by external specialists.
Availability, security signals and incidents are centrally monitored and handled according to defined processes.
Backups, recovery procedures and continuity measures support recovery after technical or operational disruptions.
Certification and assessment
DESAN operates according to certified standards for information security and research processes. External certification and assessments provide transparency for clients.

ISO 27001
The certification covers the controlled organisation and continual improvement of information security within DESAN.
