BUILDING SECURITY TO UNLOCK ENGINEERING VELOCITY
Summary from the TLDR InfoSec newsletter
Robinhood built SERA (Secure Enhanced Remote Approval), an internal platform that replaces VPN-dependent access approvals with passkey-based biometric authentication, enabling engineers to securely approve requests from any device. The system uses trusted enrollment on corporate devices to bootstrap credentials and then enables flexible remote approvals with tamper-evident audit trails, reducing approval times by over 20%. This approach demonstrates how organizations can reduce friction in security incident response and off-hours workflows without weakening authentication guarantees.
