As a full-service digital agency, we specialise in crafting websites that work hard for organisations and the people they serve.
Our Umbraco specialists work closely with membership bodies, non-profits, public sector teams, and enterprise organisations to deliver platforms that are as powerful as they are easy to use.
Whether you're replatforming, upgrading, or starting from scratch, we’re here to help you get the most out of Umbraco.
We’re proud to be the first Umbraco Contributing Platinum Partner across both the UK and the US – reflecting not just the quality of our delivery, but our deep, ongoing contributions to the Umbraco platform and community.
Our team includes certified Umbraco developers and two Umbraco MVPs. We're not just experienced, we're actively involved – constantly learning, contributing, and helping shape the future of the platform.
We’re closely involved in the Umbraco community, from hosting meetups to speaking at global events like Codegarden. Our direct involvement in the Umbraco Cloud Advisory Board, the Orchestration Advisory Board, and the Sustainability Team ensures we help shape what's next.
We help organisations adopt and migrate to Umbraco Cloud where it makes sense, enabling simpler deployments, improved security, and more efficient workflows. Our focus is always on what works best for your team, not pushing a one-size-fits-all approach.
Our Service Desk supports Umbraco platforms long after launch, with a 100% satisfaction rating across thousands of tickets each year. From maintenance and upgrades to issue resolution, we keep platforms stable, secure, and performing well, day in, day out.
We’ve delivered Umbraco platforms for organisations including the British Army, Chartered Institute of Marketing, and Youth Sport Trust. Whether you’re scaling an existing site or rethinking your digital strategy, we bring experience you can rely on.
Throughout the project, the team was professional, responsive, and knowledgeable when it came to all things UX and web development, particularly the Umbraco CMS, which really stood out to us. We’re very impressed with how user-friendly Umbraco is, and it has made our content management experience so much easier.
We’ve been delivering Umbraco solutions for over a decade, helping organisations build websites that are flexible to manage, resilient at scale, and able to adapt as needs change.
Umbraco works as part of a wider composable setup. Its API-first architecture and cloud-ready options make it easy to integrate into your wider tech stack, giving you complete control over how you build, scale, and evolve.
Umbraco’s open-source architecture gives developers the freedom to build exactly what’s needed. Use existing components where speed matters, or build bespoke functionality where requirements demand it – without compromising control or maintainability.
From CRMs and ERPs to payment systems and third-party tools, Umbraco’s API-first approach ensures smooth, secure integrations with the systems that power your organisation.
Empower your content team with a clean, intuitive interface for editing, publishing, scheduling, and translating. Umbraco supports structured workflows and grid-based layouts that help teams move fast without compromising on quality or control.
Umbraco supports complex multisite and multilingual setups with ease, making it well-suited to organisations operating across regions. Central oversight can sit alongside local flexibility, so you can scale consistently and efficiently.
Manage SEO performance without plugins or bolt-ons. Umbraco includes built-in tools for technical and on-page optimisation, supporting visibility from day one.
Backed by a strong global community and a transparent release roadmap, Umbraco is a platform that grows with you. As Platinum Partners and community meet-up hosts, we stay closely aligned with how the platform is evolving – and what that means for our clients.
Umbraco’s product organisation is ISO 27001 certified, demonstrating a structured and independently audited approach to information security across the development, maintenance, and operation of Umbraco products. This provides added assurance for organisations operating in enterprise and regulated environments.

As certified Umbraco Platinum Partners, we support organisations across the full lifecycle of their Umbraco platform – from early planning and delivery through to ongoing optimisation and long-term support.
Don’t risk performance or security by staying on an unsupported version. We’ll help you plan and execute a smooth upgrade path, ensuring your platform remains supported and scalable.
Make the most of Umbraco Cloud’s automated deployment, staging environments, and enhanced security. We handle migration and setup, so you can benefit from a smoother workflow and reduced overheads.
Our flexible Timebank packages provide 24/7 access to our expert team, ensuring issues are resolved fast, updates are managed properly, and your platform stays in peak condition.
Our Continuous Improvement programme keeps your Umbraco site evolving over time. Through ongoing UX enhancements, technical audits, and data-driven insights, we ensure your website continues to deliver value and never falls short of user expectations.
Whether you need SLA-backed day-to-day support, long-term transformation, or help navigating complex upgrades, we provide the confidence, continuity, and care you need to thrive.


Transform your website into a high-performing engagement platform using Umbraco Engage – a powerful suite of personalisation, testing, and analytics tools that put your users’ journeys at the heart of every interaction.
Leverage Umbraco Commerce to create an intuitive, high-performing e-commerce solution tailored to your business. Whether you’re launching a new store or enhancing an existing one, we ensure your platform delivers results.


Umbraco Compose is a managed data orchestration layer that simplifies complex composable architectures, enabling content and data to flow cleanly from multiple systems to multiple digital experiences. If you’re operating at enterprise scale and want to assess whether Compose is the right fit for your architecture, speak to our Umbraco experts.
Umbraco Workflows is a powerful extension for Umbraco CMS that adds structured content approval and publishing processes. It allows teams to define clear workflows, ensuring content passes through the right people before it goes live.
With features like email notifications, comments, and detailed audit trails, Umbraco Workflows supports better collaboration, governance, and accountability, making it especially valuable for larger teams or organisations that need stronger editorial control without slowing content delivery.
Smarter, streamlined and under your control.
Umbraco now takes a deliberate, open approach to AI, with a configurable foundation and modular MCP powered integrations that give organisations real choice in how and where AI adds value within their CMS.
We help organisations assess where AI genuinely enhances workflows, insight and content outcomes, improving efficiency and consistency while keeping data, governance and implementation fully under your control, without unnecessary complexity or risk.

In this blog, Cantarus CEO Lee Adams explains why moving from DNN (Platform or Evoq editions) to a modern CMS – such as Umbraco – needs to be prioritised to protect your website's performance and security.
Cantarus plays an active role in the Umbraco ecosystem, contributing not just through client work but through ongoing involvement in the platform and its wider community.
Our team includes two Umbraco MVPs, alongside certified Umbraco developers, and is supported by a culture that encourages continuous learning and provides clear opportunities to achieve and maintain accreditation.
We also contribute directly to Umbraco’s evolution – hosting community meet-ups, taking part in events such as Codegarden, and sitting on advisory groups including the Umbraco Cloud Advisory Board, Umbraco Orchestration Advisory Board, and Umbraco Sustainability Board. This close connection keeps our work grounded in real-world use and best practices, ensuring the Umbraco solutions we deliver reflect how the platform is evolving today and where it’s heading next.
