How it works


1. Member organisation exports its S21 intelligence database


2. The file is encrypted and uploaded to a secure S21 repository


3. All uploaded data is merged into one encrypted master file


4. The latest S21 Global Alliance Database is issued
Secure and reliable by design
We continue to champion best practice and compliance when it comes to managing the Global Alliance Database.
Intelligence exported is automatically encrypted, and uploaded through an encrypted platform and the master database file always remains encrypted.
All our solutions and services are totally secure and have been developed in line with GDPR and other relevant guidelines. It’s part of the reason we’re trusted by some of the most data-sensitive sectors, including policing, military, and online technology platforms.
