While different than update Safari; another idea may be
to see if there are expired secure certificates for browser.
• Digital certificates and encrypted websites in Safari on Mac - Apple Support

• Certificate Transparency : Certificate Dev

This could be alleviated should your Mac 'upgrade' later macOS.
So that can be an answer the basic issue. Or update certificates.
