'securely-integrated' originates from the combination of 'securely' and 'integrated', where 'securely' means 'in a secure manner' and 'integrated' means 'combined into a whole'.

'Securely-integrated' evolved from the need to describe systems or entities that are both secure and unified.

Initially, it meant 'combined securely', but over time it evolved to emphasize the importance of security in integration.
