Frequently Asked Questions

Why is TLS 1.0 still dangerous if the server also supports TLS 1.3?
An attacker performing a man-in-the-middle attack can force a 'downgrade' to the weakest protocol the server accepts. If TLS 1.0 is still enabled, the connection can be downgraded to exploit its known vulnerabilities.
