WitnessAI is an inline "AI firewall" that provides agentless network-level discovery of AI usage plus an intent-based policy engine for inline protection, including PII tokenization and prompt-injection blocking, founded in 2023 and headquartered in Mountain View, California. Unlike many AI security vendors, it is deployable on-premise, in a cloud sandbox, or within a customer's own VPC, keeping data and activity telemetry separated from other customers. It has raised over $85 million in funding, including a $58 million round backed by Sound Ventures, Qualcomm Ventures, and Samsung Ventures. Pricing is enterprise quote-based.
