About
Executive AI Security & Engineering Built for the Boardroom.
Led by enterprise security veteran Shantanuu Roy, CISM and CISA, NextZen Security provides high-impact AI security governance and deployment across the United States. In Australia, NextZen operates under NextZen AI.
We operate at the critical intersection of autonomous AI implementation and hardline cyber defense. Utilizing an elite, Forward Deployed Engineering model, we do not just hand over reports — we embed the guardrails, orchestrate secure data pipelines, and translate complex algorithmic risk into clear business strategy. We deliver the definitive technical foundations and auditable evidence you need to confidently face buyers, boards, and strict regulatory frameworks.

Senior-led
Every engagement carries a named senior owner from scoping through to the leadership readout.
Evidence-first
Every finding carries the control it affects, the evidence behind it and the decision it changes.

A named senior product manager leads Forward Deployed Product Management engagements, defining requirements and sequencing the backlog for engineering delivery.

Controls, evidence and audit-preparation work is led by the senior architect who scoped the engagement.
Where NextZen Security is going
NextZen Security delivers AI engineering, security architecture and assessments today. A managed AI security capability — continuous monitoring, detection and response for LLM and agentic workloads — is in development for 2027, shaped by the clients we assess now.
How the work is delivered
These commitments apply to every engagement, at every level.

Every proposal names the individuals accountable for your engagement and attaches their relevant experience.
