Company
Building a calmer way to control sensitive business content.
Casewelt is an independent product of Sial Networks Limited. We build the layer between everyday file work and the security, governance and audit decisions organisations need around it.
What we build
Useful collaboration without giving up policy.
Organisations already know how to make files. The harder problem is keeping control when those files move between teams, leave the organisation, enter a retention period, become part of a dispute or need to be explained months later.
Casewelt puts those moments in the content system itself: identity-aware access, explicit external shares, lifecycle governance, regional placement, audit and integration around the same objects.
Who operates this
A UK product company
Engineering philosophy
We favour explicit control surfaces. A denial, hold or placement conflict should appear as visible product behaviour that can be reviewed directly.

Product evaluation and architecture questions: request a walkthrough or contact@casewelt.com.
Security contact
Vulnerability and security correspondence uses the same address. Do not send production secrets or special-category data in an initial note.
How we work
Precision matters more than volume.
Product first
Start from the files, people and decisions that need control, then keep the surrounding systems — identity, monitoring, automation — in the picture.
Security in the product
Authorisation, encryption, session revocation, tenant isolation and audit are built into how Casewelt stores and serves content.
Interoperable by design
Connect Casewelt to the identity provider, SIEM and business systems you already operate, through OIDC, APIs and signed events.

Whether you are evaluating secure sharing, governance, regional control or integration, we can begin with the requirement that matters most.
