From DevSecOops to Security Success: The Bug Bounty Effect at FINN.no
summary
Since 2019 FINN.no runs a private bug bounty that outfinds static and dynamic scanners: CodeQL finds some issues but the bounty yields far more exploitable bugs, first year delivering 24 valid reports for ~$15k and total payouts ≈$200k over five years, median $200–$400, max $6,000. Automated tools (Detectify, dependency checks) flood with false positives; bounties cut average exposure from ~800 days to weeks/months. Concrete wins include a Spring Boot actuator HTTP Trace critical fixed on a Saturday, regex bypasses discovered after report disclosure, and a dependency‑confusion case that prompted an internal mitigation and tooling. Platform musts: SSO, good API, report disclosure.
