BISO (Business Information Security Officer)
A Business Information Security Officer (BISO) is a security leader embedded within a specific business unit or line of business, responsible for translating enterprise security strategy into business-specific execution and vice versa.
Why the BISO Role Exists
Enterprise CISOs cannot be everywhere. In large organizations with distinct business units, security decisions need to happen close to where the business runs, with someone who understands both the security posture and the specific commercial context. That is the BISO's role.
A BISO typically reports functionally to the CISO and operationally into the business unit leadership, sitting at the seam between the two.
What a BISO Actually Does
BISO responsibilities usually include translating enterprise security policy into practical guidance for the business unit, representing the business unit's context back to the central security function, prioritizing security investment within the business unit, and serving as the primary escalation path for security decisions specific to that unit.
Effective BISOs are typically evaluated on both security outcomes and business alignment, unusual for a security role.
BISO and the CISO
The BISO does not replace the CISO. The CISO owns enterprise strategy and reports risk to the board. The BISO operationalizes that strategy inside a specific business context, and often feeds business-unit-specific risk data back up into enterprise reporting.
