Danil Koltsov Information Security Development Manager

Progressed from hands-on Security Engineer to a management role — built the bank’s vulnerability-management function from the ground up and now own security as a horizontal function across vulnerability management, endpoint protection (EDR/EPP), application security (SAST/DAST), DevSecOps, and container security.

Act as the mandatory security sign-off for production changes and own audit and regulatory engagement (NBU, PCI DSS v4.0, SWIFT CSP; ISO/IEC 27001-aligned).

I also publish open data on how long vendors leave users exposed.
