We build things that work

ZENTAG is a UK-based web agency covering design, development and cyber security. We are a small, senior team — no account managers, no junior handoffs. You deal directly with the people doing the work, from the first conversation to the day your project goes live.

100% In-House

We do not outsource. All work is handled directly by our own team. You always know who is responsible for your project, and the quality never gets diluted.

Always Available

We work late evenings and weekends because that is often when clients need us most. Deadlines rarely fall during office hours, and neither do we.

Fully Confidential

We work with agencies on a white label basis under strict NDAs. Your clients will never know we were involved, and there are no hidden credits in the source code.

From rough idea to live product

A lot of our best projects have started as a vague concept scribbled on a napkin. If you have a problem to solve or an opportunity to go after, we can help you work out what to build, how to build it, and how to do it securely.

We bring together design, engineering and security under one roof, so nothing falls between the gaps. There is no passing the brief between teams or waiting for a third party to come back. It all happens here.

Whether you need a full project delivered end-to-end or specialist support on a specific piece of work, we are happy to talk through what would suit you best.
