Vonage has launched Protection Suite for Okta, a self-service connector for multi-factor authentication.
The connector is aimed at Okta enterprise customers that need to meet Bring Your Own Telephony requirements without building their own telephony systems. It supports SMS and voice authentication, sending one-time passwords through the Vonage Verify Network API.
The product adds fraud checks tied to mobile network data before and during one-time password delivery. Those checks are designed to address threats including artificially inflated traffic and SIM swap fraud.
According to Vonage, Okta processes tens of billions of authentications each year, and the launch targets organisations that rely on text and voice channels for login verification. The product is available through the Vonage Cloud Runtime Marketplace, which supports distribution across more than 200 countries.
Fraud focus
The connector combines routing and delivery features from Vonage Verify with fraud controls from Identity Insights and Fraud Defender. It assesses phone numbers using signals from mobile networks before a one-time password is sent, aiming to flag high-risk or compromised numbers early.
It also includes automatic SMS-to-voice fallback and carrier routing across international networks. Vonage manages sender IDs automatically to help customers comply with local rules on message delivery.
The launch comes as companies face growing pressure to tighten authentication controls as multi-factor authentication becomes more common across the workforce. Vonage cited industry data showing adoption has reached 70 per cent of workers, while SIM swap fraud rose 38 per cent in 2025.
Okta users
The product is aimed at businesses using Okta that want to avoid building and maintaining their own integrations for messaging and voice authentication. Organisations can deploy the connector on a self-service basis and move from setup to first one-time password delivery within minutes, according to Vonage.
The approach addresses a growing issue for identity teams as software providers ask large customers to bring their own telephony connections for authentication traffic. Rather than requiring custom development, the connector offers a packaged way to connect Okta workflows with Vonage messaging and voice services.
Vonage is part of Ericsson and operates within the group's Global Communications Platform business area. Its wider portfolio spans network application programming interfaces, communications platforms, contact centre software and unified communications tools.
Christophe Van de Weyer, President and Head of Business Unit API at Vonage, commented on the launch: "Enterprises using Okta need authentication that's not just fast, but trustworthy, and that means going beyond basic message delivery to actively protect against fraud," said Van de Weyer. "With the Vonage Protection Suite for Okta, we're bringing together intelligent OTP delivery and network-powered fraud protection in a single, ready-to-deploy solution, so security teams can focus on protecting their users, not building infrastructure. This makes Vonage an essential layer in identity and access management platforms."
