Overview Of SOC 2 Bridge Letter

A SOC 2 Bridge Letter is a document that provides an interim report on the status of an organization's controls and processes, in between two SOC 2 audits.  It is typically issued by the auditor who performed the previous SOC 2 audit and serves as a bridge between the two audits. The Bridge Letter provides an update on any changes that have occurred since the previous audit and may be required by stakeholders such as customers, regulators, or investors to ensure that the organization is maintaining adequate controls over its information systems. 

The SOC 2 Bridge Letter is not a replacement for a full SOC 2 audit, but rather a limited-scope report that is intended to provide some level of assurance until the next full audit is conducted.
