Pros Checks SSL support before switching; Redirects HTTP to HTTPS and rewrites resource URLs; Shows certificate details in the admin One-click HTTPS migration with 301 redirects; Hardening options such as XML-RPC and user enumeration; Email two-factor login for chosen roles in the free version
Cons Does not install or renew certificates; Rewrites output at runtime, so hardcoded http links in the database still need cleanup; Multisite support needs a network-level setup Captcha, authenticator 2FA, passkeys and firewall need Pro; Vulnerability checks send plugin and theme names to a remote service; Many settings screens to review after setup
