Is WordPress more secure than a headless CMS?

Traditional WordPress has a larger attack surface than headless CMS solutions like Sanity, Contentful, or Strapi because it exposes PHP execution, plugin code, theme code, and admin interfaces directly to the internet. Headless CMS platforms separate the content management backend from the frontend, reducing the number of attack vectors. However, headless setups introduce their own risks including API key exposure, missing authentication on API endpoints, and CORS misconfigurations. WordPress with proper hardening can be very secure, but it requires more active security management than managed headless solutions. UNPWNED scans both WordPress and headless CMS deployments for their specific vulnerability profiles.
