## Bio

Deepak Gupta founded Start with Identity, the community that writes and reviews this site. His career has been on the building side of identity: he founded the [CIAM](https://startwithidentity.com/guides/fundamentals/what-is-ciam/) platform [LoginRadius](https://startwithidentity.com/vendors/ciam/loginradius/) in 2013 and built it from scratch, serving as board member, CTO, and CISO, taking it from a social-login product to a full customer identity platform operating at consumer scale while running its SOC 2, ISO, GDPR, and CCPA programs.

He holds five granted patents spanning DDoS defense, IoT authentication, searchable encryption, and AI-based detection, has written seven books on security and privacy, and writes regularly on identity and AI security at [guptadeepak.com](https://guptadeepak.com/about/), with bylines in Forbes, Entrepreneur, VentureBeat, and Fast Company. He now leads GrackerAI, a generative engine optimization platform for B2B cybersecurity vendors.

## Where their work shows up

The generation of CIAM platforms he helped build solved a problem enterprise [IAM](https://startwithidentity.com/guides/fundamentals/what-is-iam/) was never designed for: authenticating millions of consumers who will abandon a signup form rather than call a help desk. That pressure produced the patterns the category now takes for granted, social and federated login as a first-class path, progressive profiling, consent and preference management, and regional data residency as a product feature rather than a deployment note. Compare the current field in the [best CIAM platforms](https://startwithidentity.com/rankings/best-ciam-platforms/) ranking and the [how to evaluate CIAM](https://startwithidentity.com/guides/buyer-guides/how-to-evaluate-ciam/) guide.

His current work sits on the other side of the same problem: what identity means when the thing asking for access is an [AI agent](https://startwithidentity.com/guides/fundamentals/what-is-non-human-identity/) rather than a person.
