SSL Inspection


Secure socket layer (SSL) inspection is the process of inspecting encrypted HTTPS traffic.

  • Without SSL inspection, network administrators cannot monitor encrypted traffic for threats
  • essential for:
    • verifying that website certificates are valid
    • helping protect against on-path (man-in-the-middle) attacks
    • and detecting traffic encrypted with anything other than a trusted third-party certificate
  • helps enforce organizational policies
    • ensuring that employees comply with acceptable use policies and do not attempt to access restricted content or share/upload restricted data
  • often accomplished by installing digital certificates on end devices that allow encrypted traffic to be intercepted, decrypted, and inspected by security tools before being re-encrypted and forwarded to the intended destination
  • Web proxies, load balancers, next-gen firewalls, and similar devices all support this capability
