Because the traffic is unencrypted, sensitive information such as login credentials or session tokens can be intercepted in transit, exposing users to man-in-the-middle attacks. Search engines now prioritize secure sites, and browsers display warnings for non-secure connections, creating a compelling case for migrating away from plain HTTP.
Firewall rules must be inspected to ensure they are not blocking legitimate traffic, and network routing should be validated to prevent packet loss. These steps form the foundation of a resilient posture against common threats.
