Options Technology (Options), a specialist in capital markets infrastructure, has promoted Marlena Efstratopoulou, who previously held the roles of Chief Risk Officer (CRO) and Chief Security Officer (CSO) as the firm's new Chief Information Security Officer (CISO).

Efstratopoulou first joined Options in October 2021 following the acquisition of the Fixnetix division from DXC, where she served as CSO. She succeeds John Gracey, who held the CSO position since 2017.

According to a press statement, the decision to combine the roles of CRO and CSO reflects Options's strategic shift towards a risk-driven security approach.
