GDPR and NIS2 compliance framework for public authorities
Procurement guidance for public-sector technology evaluation

Privacy context
The whitepaper presents a privacy-by-design framework for public authority communication: how to establish data processing boundaries, enforce data minimisation in messaging, manage retention obligations, and document compliance for ICO, regulators, and internal audit.
Security relevance
The security framework covers not just encryption but organisational controls: user provisioning, access revocation, device governance, group management, and audit trail - the administrative security layer that consumer apps fundamentally lack.
For your evaluation
The whitepaper includes a deployment decision framework helping public authorities select between managed cloud deployment (Sanket.Work) and on-premise deployment (Sanket.Enterprise) based on their data sensitivity, technical capability, and sovereignty requirements.
Questions about this paper
What is the main regulatory driver for public authorities to replace WhatsApp?
GDPR is the primary driver: public authorities cannot satisfy their data controller obligations for staff communication data when it flows through consumer apps like WhatsApp under Meta's own controller terms. NIS2 adds ICT resilience communication requirements. National information security frameworks add sovereignty requirements.
How long does a public authority procurement and deployment take?
Procurement timelines vary by authority type and procurement framework. Typical deployments range from weeks for smaller authorities using Sanket.Work to several months for larger on-premise deployments requiring security assessment. Contact Tosh Defence Private Limited for a specific assessment.
