Industrial Cybersecurity & OT Risk calculator
MFA Rollout Payback Calculator
Use this calculator to estimate payback for a multi factor authentication rollout focused on OT access paths. It helps compare investment with expected savings from lower incident exposure, better audit outcomes, and reduced account misuse risk.
What this calculator does
- Estimate payback for MFA rollout on OT remote access and privileged access paths.
- Use it when evaluating MFA for vendor portals, jump hosts, engineering access, and privileged OT accounts.
- The result estimates financial payback for MFA rollout.
Formula used
- Net annual MFA savings = annual MFA risk reduction savings - annual MFA support cost
- MFA rollout payback period = MFA rollout investment รท net annual savings
Inputs explained
- MFA rollout investment: Include licenses, identity integration, jump host changes, user enrollment, support labor, testing, training, and vendor onboarding.
- Annual MFA risk reduction savings: Use expected savings from reduced remote access exposure, fewer account incidents, lower audit remediation, and avoided downtime scenarios.
- Annual MFA support cost: Include token replacement, help desk support, vendor management, license renewals, exception review, and account administration.
How to use the result
- Use it to prioritize remote access controls, privileged account protection, and audit remediation.
- It assumes MFA is implemented in a way that supports safe OT operations and emergency access procedures.
Common questions
- What is the MFA rollout payback calculator for? It estimates payback for adding MFA to OT remote access or privileged access paths.
- What information should I enter? Use rollout investment, annual savings, and annual support cost.
- What does the result tell me? The result helps decide whether MFA investment is financially justified.
- When is the result only an estimate? It is only an estimate when user count, license cost, support workload, or risk reduction assumptions change.
