Reddit has named Allison Miller as Chief Information Security Officer (CISO) and VP of Trust. Miller is an industry expert and innovator, having spent the past 20 years scaling teams and technology that protect people and platforms, and pioneering the development of real-time risk prevention and detection systems running at internet-scale. She has also led major initiatives to engineer the defenses for core payment and e-commerce systems and deliver capabilities into key technologies that protect consumers from online threats. Miller will oversee the Safety and Security teams at Reddit where she’ll be responsible for expanding trust & safety operations and data security, as well as evolving programs to mitigate security challenges and risks. Miller will also redesign Reddit’s trust frameworks and transparency efforts to enable further growth across the platform. 

"As we evolve the policies, technology, and teams that we have in place at Reddit, the integrity of our platform and company continues to be of great importance. We have significantly expanded Reddit’s Safety and Security efforts over the past several years, not only growing teams that are dedicated to these areas but also doubling down on fundamentals that have protected our platform. We consistently share many of our practices, developments, and findings with the community, including in r/redditsecurity. These efforts have become deeply rooted in Reddit’s DNA and are a core component of our approach to bringing community and belonging to everyone in the world," says a release.

Miller joins Reddit from Bank of America where she was overseeing technology design and engineering delivery for the company’s information security organization. She has worked across myriad problem spaces affecting consumers on the internet including fraud, spam, phishing, malware, authentication, and account security, as well as those faced by large platforms including perimeter defenses, monitoring strategies, application security, and vulnerability management. Miller previously held technical and leadership roles at Google, Electronic Arts, Tagged/MeetMe, PayPal/eBay, and Visa International. 

Miller is an advocate for improving approaches to security, fraud, and user/account security. She also speaks internationally on related topics, presenting independent research as well as on behalf of employers. Miller has served on advisory and board roles for organizations such as the Center for Cyber Safety and Education, ISC(2), SIRA, and Keypoint Credit Union. She has a B.S. in Economics from the University of Pennsylvania and a Master of Business Administration from the University of California at Berkeley.  

In her spare time, Allison enjoys listening and playing to music, working on various art projects she has in progress, and trying to get through the wobbly stack of books that keeps growing. You might spot her in one of her favorite subreddits including r/dataisbeautiful, r/imaginarysubwaymaps, or r/mildlyinteresting.

“I’m excited to be joining Reddit’s team, and this is a great time to jump into the mix. Looking at the last year alone, it has been impressive to watch the pace of infrastructure and feature launches to meet the demands of new customers and increasing traffic on Reddit. Now is the perfect time to make sure that the platform’s security and trust systems are flexible and resilient enough to support the next phase of transformation,” said Miller. “I see a huge opportunity to help scale the platform’s safety infrastructure, strengthen existing cybersecurity measures, and improve the suite of capabilities that protect Redditors, their accounts, and the integrity of their communities.” 

Miller begins immediately and will report directly to Reddit CTO Chris Slowe. “We’re overjoyed to have Allison bring her extensive technical acumen and executive leadership to the Reddit family,” said Chief Technology Officer, Chris Slowe. “She will play an instrumental role in helping to ensure that our platform is safe for our users, trusted to act with integrity, and secure against adversaries big and small.”
