What is holding Slack back
- PKCE and client registration, 4 points lost. Neither PKCE nor a registration path is published. Fix: Require PKCE with S256 and support client ID metadata documents or dynamic client registration for approved agent clients.
- Documented delegate and data sharing controls, 4 points lost. No public page on delegate access or connected app controls was found. Fix: Publish a help page on delegate access and add a connected apps screen where customers revoke access.
- Sign in page loads for a declared agent in a browser, 4 points lost. The sign in page did not load for an agent or a standard automated browser. Fix: Serve the sign in page to verified agent browsers, and use signed agent identity to separate them from attackers.
- Structured data on the home page, 3 points lost. No JSON LD structured data was found on the home page. Fix: Add JSON LD for your organization type, Product or Service, Offer and FAQPage on the pages customers ask about most.
