nsKnox has launched AI Agent Caller, a new addition to its PaymentKnox suite that replaces manual vendor verification callbacks with an autonomous, multilingual voice agent. The company announced the launch on July 1, positioning it as a way to close a persistent gap in business payment security: the manual phone call finance teams still make to confirm a vendor's bank details before wiring funds.

What the agent does

AI Agent Caller is built to handle the entire callback process end to end — scheduling the call during the payee's local business hours, conducting the conversation in the payee's own language, and producing a recording, transcript, and audit trail automatically. nsKnox says the agent is context-aware rather than script-bound: it understands the specific validation context of each call, confirms the vendor's identity, and asks the payee to verify data points such as the last digits of a known bank account, without requesting or exposing full account details.

The agent integrates directly into PaymentKnox's "Work Canvas," letting a finance team trigger a call from any payee record. Once the call finishes, the recording and summary appear next to the results of nsKnox's existing banking-data validation checks, Quick Check and KnoxVerify, so a human reviewer sees both the automated verification and the live-call confirmation side by side before approving a payment. The company says the feature is available immediately to PaymentKnox customers.

Why nsKnox is targeting callback fraud

nsKnox frames the launch around the cost of business email compromise (BEC) fraud, which it says has caused more than $43 billion in losses over the past five years, with 83% of large enterprises reporting they have been targeted by payment fraud. Manual callback verification — a human calling a known vendor contact to confirm payment details before a transfer — is a common anti-fraud control, but nsKnox argues it is inconsistent, hard to scale across languages and time zones, and difficult to audit when done ad hoc by finance staff.

By making the callback itself an automated, recorded, and consistently structured step, nsKnox is betting that finance and accounts-payable teams will treat verification as a system-enforced control rather than an optional manual task that gets skipped under time pressure — while keeping a human in the loop to review, rather than approve, each outcome.

Part of a broader payments-security push

The launch builds on nsKnox's existing PaymentKnox platform, which validates vendor bank accounts against authoritative banking data before payments go out. Pairing that validation with an autonomous verification call reflects a wider trend among B2B fintech and security vendors — also visible in recent voice-agent launches from other verification and support platforms — of turning manual verification steps that are prone to human error or social-engineering attacks into supervised, agent-run processes with a full audit trail attached.
