TLS Certificates with AWS Certificate Manager

Issue and attach certificates that encrypt data in transit.

Encryption in Transit

Encryption in transit protects data as it moves across networks using TLS (Transport Layer Security), the protocol behind HTTPS.

Without it, attackers on the path could read or tamper with traffic. TLS requires certificates, and managing those is where ACM comes in.

What ACM Provides

AWS Certificate Manager (ACM) provisions, manages, and renews TLS certificates for AWS services.

  • Public certificates from ACM are free.
  • ACM handles renewal automatically, removing the risk of expired certificates.
