The secret police was key to the Soviet government (so-called Chekism), so its structure changed frequently in response to state political needs.
Note that the renaming and restructuring was fairly transparent to the population, and there was no "rebranding" effort - security officers were informally called "Chekists" up until the dissolution of the USSR.

An "umbrella" organization such as the Cheka was literally made up of hundreds of sub organizations with different purposes.
These suborganizations were recombined at various times under different chiefs to constitute new organizations with slightly different (mostly) internal mandates, and new umbrella organizations, with new names were created most of these times. For instance, the secret and non-secret police merged and de-merged from time to time.
The only thing that was constant was the ever-presence of the "organs." The forms often changed but the substance, seldom.
