CMS Buyers Guide for Government and Enterprise

Tags: Platform Strategy

Published: March 2025 | 12 min read

Choosing a CMS is one of the most consequential technology decisions a government or enterprise organisation makes. Get it right and you have a platform that serves your team and your users for a decade. Get it wrong and you spend years managing workarounds, migration debt, and vendor lock-in.

This guide is for digital leaders, procurement teams, and technical architects who need to evaluate CMS options with rigour. It covers the key decision dimensions, a comparison of the main platform categories, a procurement checklist, and the questions you should be asking vendors.

1. Understanding the Platform Categories

Before comparing specific products, it helps to understand the four broad categories of CMS available to Australian government and enterprise organisations:

GovCMS

A Drupal distribution managed by the Digital Transformation Agency (DTA) for Australian government. Hosted on AWS GovDC, IRAP assessed to PROTECTED, and available to all federal and state agencies.

Custom Drupal

A bespoke Drupal implementation built to your specific requirements. Gives you full control over content architecture, integrations, and hosting. Requires more internal or partner capability to operate.

Headless CMS

A content-first platform that delivers content via API to a separately built front-end. Examples include Contentful, Sanity, and Strapi. Excellent for multi-channel content but requires a capable front-end team.

Proprietary CMS

Vendor-owned platforms such as Sitecore, Adobe Experience Manager, or Squiz Matrix. Often feature-rich but carry higher licensing costs, vendor lock-in risk, and limited open-source community support.

2. Platform Comparison

The table below compares the four platform categories across the dimensions that matter most for government and enterprise procurement:

3. Decision Framework

The right platform depends on your context. Here is a practical decision framework based on common scenarios:

If you are an Australian government agency

Start with GovCMS. It is the default for a reason: IRAP PROTECTED, DTA-approved, whole-of-government licensing, and a strong local community. Only deviate if your requirements genuinely cannot be met.

If you need complex integrations or custom architecture

Custom Drupal on approved hosting. GovCMS is a constrained distribution. If your platform needs deep API integrations, custom content models, or bespoke workflows, custom Drupal gives you the full framework without the distribution constraints.

If you are an enterprise with a strong front-end team

Consider headless Drupal or a headless CMS. If your front-end team wants full control of the presentation layer and you have the capability to manage two systems, headless architecture can deliver excellent results.

If your primary need is marketing content, not service delivery

A proprietary CMS may be appropriate. If the platform is primarily a marketing site with simple content needs and no government compliance requirements, the editorial experience of platforms like Contentful or Sanity may justify the trade-offs.

If you are unsure

Run a structured discovery. A 4-week discovery process with stakeholder interviews, content audit, integration mapping, and a platform assessment will save years of regret. This is the work Doghouse does well.

4. Procurement Checklist

Use this checklist when evaluating CMS vendors and platforms. Each section covers a distinct evaluation dimension. A strong platform should be able to answer yes to most questions in each section.

Content & Editorial

• Can editors create and manage content without developer support?
• Does the platform support structured content (content types, fields, taxonomies)?
• Is there a preview mode that reflects the live site accurately?
• Can workflows (draft, review, publish) be configured without custom code?
• Does it support multilingual content natively?

Accessibility & Standards

• Does the platform meet WCAG 2.2 AA out of the box?
• Are admin interfaces keyboard-navigable?
• Does the platform support ARIA attributes in content output?
• Is there a mechanism to enforce alt text on images?
• Has the platform been independently audited for accessibility?

Security & Compliance

• Where is data hosted? Is it within Australian jurisdiction?
• Has the platform or hosting environment been IRAP assessed?
• How are security patches delivered and how quickly?
• Does the platform support SSO (SAML, LDAP, Azure AD)?
• Is there a documented incident response process?

Integration & Architecture

• Does the platform expose a REST or GraphQL API?
• Can it integrate with your existing identity provider?
• Does it support headless or decoupled architecture if needed?
• What is the migration path from your current platform?
• Can the platform scale to your peak traffic requirements?

Total Cost of Ownership

• What are the licensing costs over a 5-year horizon?
• What internal capability is required to operate the platform?
• What are the training costs for editors and administrators?
• What does a typical upgrade cycle cost in time and money?
• What are the exit costs if you need to migrate away?

Vendor & Community

• Is the vendor financially stable and committed to the platform long-term?
• Is there an active open-source community or ecosystem?
• Are there local (Australian) partners with proven delivery experience?
• What does the vendor's support SLA look like?
• Are there reference customers in Australian government or enterprise?

5. Common Mistakes to Avoid

Choosing on features, not fit

Every CMS vendor will show you a demo that makes their platform look perfect for your use case. The question is not whether the platform can do the thing in the demo. It is whether it can do the things you need, at the scale you need, with the team you have.

Underestimating content operations

The best platform in the world fails if editors cannot use it confidently. Content operations — how your team creates, reviews, approves, and publishes content — should be a primary evaluation criterion, not an afterthought.

Ignoring migration costs

Moving from one CMS to another is expensive. Content migration, URL mapping, SEO preservation, integration rewiring, and staff retraining all have real costs. Factor these into your TCO calculation before you commit.

Treating accessibility as a compliance checkbox

WCAG 2.2 AA is a legal requirement for Australian government and a quality standard for enterprise. Platforms that treat accessibility as a feature to be added later will cost you more to remediate than platforms that build it in from the start.

Skipping discovery

The most expensive CMS decision is the one made without a proper discovery process. Four weeks of structured discovery — stakeholder interviews, content audit, integration mapping, and platform assessment — will save years of regret and hundreds of thousands in rework.

The Doghouse View

We have built and migrated platforms across Australian government and enterprise for nearly two decades. The platforms that succeed long-term are not always the most technically impressive. They are the ones that match the delivery model to the service model — and that are built with enough discipline to stay maintainable as the organisation evolves.

If you are at the start of a CMS evaluation and want a structured, independent assessment, that is work we do well. We are not tied to any platform vendor. We will tell you what fits your context, not what is easiest for us to sell.
