CISO as a Service
Andersen CISO as a service provides strategic leadership and security direction from a certified executive who owns your program, drives compliance, and implements effective security controls. The result is a stronger security posture without the cost of a full-time hire.
When your business needs CISO as a service
A compliance deadline or a failed audit
A recent compliance audit has exposed control gaps your team cannot close. A CISO steps in immediately, assigns evidence owners, drives an audit calendar, and closes every requirement before the review date, reducing overall compliance risk.
No security leadership after rapid growth or funding
Rapid growth or funding brings scalability demands that outpace controls. Without cybersecurity leadership, risk accumulates. A CISO builds the risk register and security roadmap from scratch.
Recovering from a security incident
A breach or ransomware event leaves leadership without a recovery path. Andersen assigns a CISO who leads the post-incident review, coordinates exposure remediation, and implements controls that prevent repeat attacks.

Benefits of CISOaaS
Executive security expertise on demand
Andersen gives clients direct access to a CISSP- or CISM-certified security leader with expertise. A chief information security officer as a service engagement keeps decisions consistent without the lead time or overhead of a permanent hire.
Cost efficiency compared to a full-time CISO
A CISOaaS engagement replaces a full-time CISO salary — typically $250,000–$400,000 annually — with a monthly retainer or project-based engagement, directing budget towards controls.
Faster compliance and audit readiness
Structured compliance programs reduce time-to-first-audit by maintaining a live audit calendar and assigning evidence owners. Closing control gaps in targeted sprints accelerates certification readiness.
Stronger security posture
A gap analysis and risk-based remediation backlog raise security maturity against NIST CSF or recognized security benchmarks, giving leaders a measurable, quarter-by-quarter view of posture improvements.
Security aligned with business priorities
The CISOaaS engagement model scales with your business — expanding during audits or incident response and easing back when risk stabilizes — so security investment matches your need.
Clear security priorities and roadmap
Andersen delivers a structured security roadmap with defined milestones, assigned owners, and trackable outcomes, replacing ad-hoc decisions with a holistic security management plan.
