# Supabase disables four outdated TLS 1.2 cipher suites starting November 10

> Four CBC-mode TLS 1.2 ciphers will be removed from project HTTP APIs due to known security weaknesses. Less than 0.0001% of connections used these ciphers in the past 30 days, but devices on end-of-life operating systems or old browsers that only support them will lose access and require OS or TLS library updates.
