Hackers are well aware that applications often transact their data across certain specific ports. They know how to scan your ports for vulnerabilities and openings across your defense posture to see what is left open on the internet. By bundling transactions securely across port 443 using SSL/TLS encryption, TAC enables you to lock away your applications from the prying scans of hackers. Even if your application has vulnerabilities hackers might exploit, TAC prevents this – because hackers cannot see your applications to identify which ones are vulnerable enough to exploit in an attack.
