Abhishek Bansal and Rashi Haldiya explore financial impacts of breaches beyond direct costs, focusing on developing data-driven quantification models to optimize security budgets and justify investments.

For CISOs, understanding the true financial impact of a cybersecurity breach is critical for building a strong risk management strategy and securing executive buy-in for security investments. Beyond direct costs such as ransomware payments, regulatory fines and incident response expenses, breaches impose hidden costs, including brand reputation damage, legal liabilities, customer churn and long-term operational disruptions. With increasing cyber insurance premiums and regulatory penalties under frameworks such as GDPR and the DPDP Act, CISOs must develop data-driven models to quantify breach impact, optimize security budgets and justify proactive cybersecurity investments.

The session will cover: 

  • Developing a cybersecurity risk quantification framework;
  • Aligning security budgets with risk appetite and business goals;
  • Analyzing financial damages from past cybersecurity incidents.

Here is the course outline:
