Encryption in Transit
Definition
Transport encryption protects data during transmission between defined endpoints.
The protection of transmitted data through a cryptographically secured channel, usually TLS, between clearly defined endpoints.
Simply explained
Your message travels through a protected connection channel. The protection applies to the path between its two ends.
Why it matters in practice
The term contributes to secure, maintainable, and high-performance web applications as well as resilient technical decisions.
Example from business
An operation enforces TLS between browser, gateway, and internal services and verifies certificates.
Limits and pitfalls
- Encrypted segments leave proxies or endpoints unprotected; TLS termination and metadata must be documented.
Origin & history
TLS and IPsec standardized transport and network protection for Internet communication.
Use in mid-sized companies
- Possible example: An operation enforces TLS between browser, gateway, and internal services and verifies certificates.
