Con Insecure off-premise storage
To properly use this with full development and testing it stores API details, including security, in an off-site storage managed by Postman. It also stores details about employees, teams they are members of, and projects they are working on.
This makes it inappropriate for any organization that is required to exercise a high level of security hygiene when developing software products. This issue may be compounded by the lack of details concerning the geolocation of data storage.
