Sumit Ranjan

I like to build AI agents, break them, and teach others to do both.

13 years ago I was fitting logistic regressions. Then came CNNs, self-driving cars (I wrote a book on that), and LLMs, which I've trained, fine-tuned and put into production for enterprises and governments.

Then the models started acting on their own, and I got more interested in how they break. I helped write the OWASP Top 10 for agentic AI, open-sourced models that catch prompt injection in text and voice, and I'm doing a PhD on keeping agent behaviour predictable.

I teach all of it at IIT Roorkee, IIT Gandhinagar and universities in Dubai, because nothing tests your understanding like a room full of students.

Defences for AI that acts on its own

Models, platforms and research for keeping language models and agents safe in production. Most of it follows the same loop: build the system properly, attack it the way a real adversary would, then turn whatever breaks into controls that ship. That covers everything from a spoken prompt to a tool call, and the regulations an agent has to satisfy before a bank will let it run.

Controls attached when an agent is created, not after it ships.

Platform architecture

A governance-first platform for building AI agents in regulated finance

Banks and insurers want agents, but they can't deploy what they can't audit. I designed a platform where security, policy, risk and regulatory controls are part of how an agent is defined. It comes with a red-teaming suite and guardrails for prompt injection, data exfiltration, toxicity and unsafe tool use.

MedicoVerse: summarising pharmaceutical regulatory documents

Dalal, Ranjan, Bopaiah, Chembachere, Steiger, Burns, Daswani

Regulatory teams spend days reading dense submissions. MedicoVerse groups a document's meaning with SapBERT embeddings and hierarchical clustering, summarises each cluster, and tags diseases and chemicals, so reviewers get a short summary that keeps what matters.

We scored models on a weighted metric built for the job: ROUGE, BERTScore, readability, and a business KPI worth 40% of the score. The value for pharma is fewer regulatory queries, shorter project timelines and lower cost.

About

From building models to securing them

I started in 2014 analysing data from semiconductor manufacturing equipment. Since then I've followed the technology one step at a time: models that see, then models that read and write, and now agents that take actions on their own.

Since 2024 I've focused on one question: how do you let an AI agent act on its own and still trust it? My PhD at BITS Pilani studies ε-bounded determinism, which means putting limits on how much an agent's behaviour can vary so it can be tested, audited and trusted. I've led Responsible AI work for government programmes in the Gulf and I advise enterprises on AI security.

I split my time between Bengaluru and Dubai.

I came to security from the model side. Having trained, fine-tuned and shipped these systems myself, I know where they give way.
