What is a WISP?

Written Information Security Plan

A Written Information Security Plan (WISP) documents exactly how your firm protects sensitive client information and meets regulatory standards.

Clear designation of internal roles, permissions, and multi-factor access protocols.

Ongoing evaluation of internal vulnerabilities and third-party software vendors.

Clear protocols for workforce security, threat mitigation, and breach recovery.

3-2-1 backup strategies and scheduled policy updates as your firm grows.

A WISP should reflect how your firm actually operates and should be reviewed regularly as your business changes.
