nonsecure

Lacking proper protection

Nonsecure describes something lacking security protections or safeguards.

Most often applied to digital contexts: a nonsecure website doesn't encrypt data, a nonsecure connection leaves information vulnerable to interception.

The term also applies to physical spaces: a nonsecure area of an airport is accessible without passing through screening.

Sometimes hyphenated: non-secure.
