Is your organization still using the SSL/early TLS protocols? Do you work with online and e-commerce partners or customers who haven’t yet started the migration away from SSL/early TLS to a more secure encryption protocol? There are many serious vulnerabilities in SSL and early TLS that left unaddressed put organizations at risk of being breached.  As there are no fixes or patches that can adequately repair SSL or early TLS, it’s critically important that organizations upgrade to a secure alternative as soon as possible, and disable any fallback to both SSL and early TLS.
