Reddit’s Allison Miller builds trust through transparency

Miller joined the social media company in February 2021, assuming a range of responsibilities, from security and privacy to trust and safety, that reflect broadening of the CISO position itself—a role she summarizes as “keeping shenanigans from impacting a good user experience.”

Allison Miller’s official title—CISO and vice president of trust—says a lot about her role and responsibilities at Reddit.

Like all CISOs, Miller oversees the cybersecurity strategy and operations at the 16-year-old company. She’s also in charge of privacy, ensuring that Reddit safeguards data against illicit uses and unauthorized access.
