Introducing Enhanced Security Mode: Enterprise-Grade Audio Security for Voice AI

Voice AI adoption in regulated industries has hit a wall. Not a technical wall. A physical one. When an AI agent speaks loudly, it broadcasts information into open space, exposing secrets and potentially private information that anyone can overhear. Compare this to the discrete quietness of chat, and this becomes the biggest barrier to a secure enterprise voice deployment.

That's why today, Vapi is excited to unveil Enhanced Security Mode, the most secure and quietest audio privacy layer ever deployed in an enterprise voice AI platform.

The engineering problem

Nikhil Gupta, Vapi's Co-founder and CTO, has a unique perspective on some of the challenges that made creating this feature especially complex:

“The naive assumption was that making something quieter is less important than making it louder. I want to dispel that myth entirely.

Our entire audio pipeline, codec selection, noise floor calibration, jitter buffering, and synthesis tuning is engineered for maximum intelligibility. The question then became: how do we reverse-engineer this? Every architectural decision we’ve made over the past three years optimizes for signal presence. Enhanced security mode required us to invert that at every layer simultaneously, without introducing latency artifacts that would make the output sound compressed rather than attenuated.”

What compliance teams are saying

The early access cohort included organizations across healthcare, benefits administration, and post-acute care. Their feedback was consistent: Enhanced Security Mode removed the primary objection to enterprise approval of voice AI by making private conversations impossible to overhear.

"We operate in a highly regulated environment where every word our agents say is a potential audit finding. Enhanced Security Mode was the first solution our security and compliance teams aligned on without a single objection." — Michael Parker, Chief Compliance Officer, Meridian Health Partners.

"Enhanced Security Mode gave us the confidence to expand our voice AI program into markets we'd previously considered too high-risk." — Priya Nambiar, SVP of Digital Operations, Continuity Benefits Group.

"Centuries of proven human security practice, applied to our entire agent fleet overnight. Our board asked why we didn't have this sooner. " — Bryan Batner, CTO, NorthPoint Care Solutions.

Available now

We at Vapi view ambient exposure as one of the most significant risks to enterprise security. Enhanced Security Mode applies a time-tested human security practice at a scale and consistency that no human team could hope to achieve. Every word your agents say, across every concurrent session, reaches only the intended listener.
