Aaron Ott

VP, Application Security

Aaron Ott is Rule4’s Vice President of Application Security. Before joining Rule4, he spent seven years at a nationally recognized professional services firm, where he focused on application security, infrastructure security, and DevOps. His experience also includes roles at B2B media companies UBM Canon and VideoBloom, where he built scalable application platforms for front-end content and user management.

Aaron is a passionate opensource contributor, user, and advocate. He previously curated the Boulder Drupal meetup and has contributed code to the Drupal core code base as well as numerous modules. Coming from the application development world, he has experienced the realities that often lead to shortcuts, and has found a passion in advocating for secure coding practices. This led him to expand into application security, including securing IoT devices and APIs. He is also a member of the DEF CON Group 720 (dc720).

When he steps back from his keyboard, Aaron likes to ski, solve puzzles, and hunt down new craft beers. He loves spending time with his wife and daughters, and they enjoy hosting friends for wine tasting, pool, darts, and UFC fight nights.
