1Operational resilienceCyber & resilienceIdentified$5M–$15M
The Mizuho Financial Group brief flags this opportunity: Operational resilience. Lead with a fixed-scope 4-week entry offer that proves value quickly, then grow it into the remediation program and a managed resilience testing service.
From opportunity: Operational resilience
- Why now
- Global CIB push (Greenhill acquired) alongside domestic recovery and IT stability after past outages.
- Buyers
- CISO · Chief Risk Officer · CIO · COO
- Our sponsor
- Accenture Security lead for Financial Services, with the Technology MD for the account

- Proof points
- Cyber and operational resilience case studies
Deal size$5M–$15M
Pursuit cost$125K
Win probability35%
Estimate: Estimate. Pursuit cost is about 25 person-weeks of account, sponsor and SME time at a blended $5,000 per person-week. The entry offer itself is a fixed fee of roughly $180k, or an Accenture investment if the pursuit is contested. The deal range is the 12-24 month follow-on (the remediation program and a managed resilience testing service), scaled for an extra-large (G-SIB or global leader) client from a reference range of $5-15M. It is not based on client budget data. Win probability of 35% is a planning assumption for a Mega Diamond.
