Question 1

How do you calculate cybersecurity ROI?

Accepted Answer

Cybersecurity ROI is calculated by comparing annual risk exposure (average breach cost for your industry multiplied by company size factor) with the risk reduction achieved through implemented security measures. Each measure (firewall, EDR, SIEM, pentests, etc.) reduces risk by a specific percentage. ROI = savings from risk reduction / security investment cost.

Question 2

What is the average cost of a data breach?

Accepted Answer

According to the IBM Cost of a Data Breach 2024 report, the average breach cost varies by industry. Financial sector averages $5.9M, healthcare $4.7M, manufacturing $3.8M, and e-commerce $3.2M. Costs include data loss, downtime, regulatory fines, incident response, and reputational damage.

Question 3

Which security measures provide the highest ROI?

Accepted Answer

The highest risk reduction comes from: SIEM/SOC (security monitoring) at 20% reduction, Backup & DR at 18%, EDR/XDR (endpoint protection) at 15%, and PAM/MFA (access control) at 14%. Combining multiple security layers is key, as their effects compound multiplicatively.

Question 4

How do you justify cybersecurity budget to the board?

Accepted Answer

The most effective approach is a data-driven ROI analysis: compare the cost of a potential incident (data loss, downtime, GDPR/NIS2 fines) against the cost of security measures. Typical cybersecurity ROI ranges from 3-8x. Additional arguments include regulatory requirements (NIS2, DORA), reputation protection, and business continuity assurance.
