Security first

Secure by default. Every site, every upgrade.

Security isn't an add-on; it's how we work. Every upgrade closes known vulnerabilities, every site we touch gets hardened, and every customer credential we receive is encrypted and deleted when the job ends.

Advisory monitoring

We track every Umbraco CMS, Forms and package security advisory against the exact versions you run.

Penetration testing

Authorised, Umbraco-focused pen tests covering the backoffice, APIs, forms, uploads and known CVEs.

Hardened hosting

Isolated hosting with WAF, TLS, security headers, locked-down backoffice and tested backups.

Patch fast

When a high-severity advisory lands, retainer clients are patched as a priority, not left in a queue.

Safe data handling

Upgrades run on staging copies with verified backups and a rollback plan for every go-live.

Encrypted credentials

Access details you share are encrypted at rest, seen only by our team, and purged when the job ends.

20+years building Umbraco sites

Experience you can trust

We've upgraded through every era of Umbraco.

We've been developing Umbraco sites for more than two decades, since the earliest versions of the CMS. We've lived through every major change: the move from WebForms to MVC, from .NET Framework to .NET Core, and from the AngularJS backoffice to today's web-component backoffice.

That history matters when you upgrade. We know where old sites hide their custom code, which packages died along the way, and how to move your content safely from one era to the next.

  • v3 – v7WebForms & early MVC, XSLT macros, the classic backoffice
  • v8Variants, Nested Content and the end of .NET Framework
  • v9 – v13.NET Core & .NET 5–8, Block List and Block Grid
  • v14 – v18The new web-component backoffice on .NET 9 & 10

No job too small.

Need a minor or patch upgrade within the same major version? A single security fix? A package that won't play nicely after an update? We take on small upgrades too, usually fixed-price and turned around in days, not weeks.

Monthly retainers

We watch security advisories for your exact version.

Umbraco publishes security patches regularly. On a retainer we track every advisory against the Umbraco and package versions you run, tell you when one affects you, and patch it for you.
