Question: I'm looking for a content management system that can handle multiple websites and has robust security features.

Kontent.ai is a powerful AI-based CMS that automates content operations and delivers content to any channel or device. It offers Governance and Security for enterprise-level security and compliance, Author Assist for AI-based content creation, and Publish Assist for automated publishing workflows. It's geared for companies with multiple sites, with tools for knowledge management, omnichannel delivery and content hubs.

Another option is DNN, a full-featured ASP.NET-based CMS that includes web content management, CRM, marketing and social engagement tools. It's got an AI CoPilot, fine-grained user controls, multisite management and built-in security processes, making it a good choice for companies like government, finance and education that need a large, secure system.

For a flexible and extensible foundation, Payload is an open-source, headless CMS written in TypeScript and React. It can handle AI-generated content, visual editing and has features like SSO integration, access control and custom component integration. It's good for agencies, marketers and developers who want to build their own business applications.

Last is Sanity, a flexible and collaborative foundation for digital experiences. It's got real-time collaboration, GROQ for precise content querying and localization for consistent messaging. With APIs to tools like Shopify and Mux, and a Content Lake for decoupled backend operations, Sanity is good for e-commerce, marketing sites and product management. It integrates with frameworks like React and Vue, and has lots of documentation to get you started.
