Our mission -- Make secure publishing simple.

We believe teams should be able to create and maintain high-quality web experiences without wrestling with fragile tooling or risky shortcuts. CastleCMS is designed to bring structure, safety, and speed to content operations—especially for organizations with approvals, compliance, and large-scale publishing needs.

Security isn’t an add-on

CastleCMS is built on Plone’s security-focused architecture and mature permissions/workflow model—so governance is part of the platform, not a patch later.

Built for real collaboration

From drafts to reviews to publishing, CastleCMS supports teams that need clear roles, accountability, and predictable workflows.

A platform you can grow into

Whether you’re launching a new marketing site, consolidating document libraries, or building a portal/intranet, CastleCMS is designed to scale in content volume, complexity, and users.

• Organizations with compliance needs (policy-heavy, regulated, or high-security environments)
• Teams managing lots of content across sections, departments, or sites
• Groups that need approvals and a clear editorial process
• Sites that rely on document discovery (manuals, PDFs, publications, archives)

Practical guidance

We help you pick the right structure—content types, workflows, navigation, and search—before you build.

Clean implementation

We favor maintainable solutions that match your brand and requirements without locking you into a brittle customization.

Long-term partnership

CastleCMS is built for longevity. We focus on stability, predictable upgrades, and sustainable operations.
