SIAL Networks develops three products. Casewelt governs how sensitive files are shared, kept and audited. SialFlow runs image, video and document processing as durable jobs. Trustwelt, the newest, decides whether a sign-in should be trusted from the person, the enrolled device and its state, and lets a team use company logins without seeing the password. When the work is larger than a product, the same team builds the surrounding systems.
Products
Three products, each with a clear job. Casewelt governs sensitive files. SialFlow processes images, video and documents. Trustwelt decides whether a sign-in should be trusted. Start with the one that matches the problem in front of you.
Casewelt · Secure content management
Store, share and keep control of business documents. Policy, retention, legal hold and audit stay attached to the same file your team already works on.
Share the document, not the workspace
A typical use
Share an approved board pack with two named external auditors for a fortnight, pinned to one version, without opening the wider workspace.
SialFlow · Programmable media workflows
Resize, crop, reformat and compose images at request time. Heavier work such as bulk processing, video encoding and document extraction runs as durable jobs with quotas, retries and inspectable history.
Image · video · documents
POST /v1/images/{id}/bg-remove { "format": "png" } → 202 job kind=bg_remove poll GET /v1/images/jobs/{id}
Trustwelt · Device trust and company logins
Access is decided on the server from the person, the enrolled device and its current posture. Shared company logins are used through the browser extension and never revealed, and a free desktop vault keeps personal secrets on the person’s own computer.
Use the login, never see the password
A typical use
Four people post from the company LinkedIn page. None of them knows the password. When one leaves, their grant is removed and the password stays where it was.
Status
Accounts are opened on request.
Why SIAL Networks
The same people who build and run Casewelt, SialFlow and Trustwelt take on selected client programmes.
Casewelt, SialFlow and Trustwelt are developed and operated in-house, so product decisions and client work share the same engineering team.
The products grew out of systems that had to stay up: edge traffic, media delivery, security and day-to-day operations.
Architecture, application code, platform, security and migration can be covered without handing the work across organisational boundaries.

CDN and streaming delivery, edge caching and image and video processing paths.
