Every security architecture has an expiration date.
Most organizations simply do not know when it arrives.
An architecture may have been carefully designed, properly documented, and well defended when it was introduced. It reflected the business, technology, threat environment, and operational assumptions of its time.
Then the organization changed.
It adopted cloud services. It acquired another company. Employees became more distributed. Vendors received deeper access. Applications became API-driven. Automation expanded. AI entered business workflows. Identity became the connective tissue between systems that no longer shared a traditional perimeter.
The architecture did not suddenly fail.
It aged.
