Why do we need to reinvent Zero Trust now?

At its core, Zero Trust assumes no entity — inside or outside the network — should be trusted by default. Every interaction is verified, every access is treated contextually, and every device, user, and transaction must continuously prove it belongs.

The problem? Today’s environments are complex. On average, companies use an average of 342 SaaS apps, and employees use 2.5 different devices per day. Contractors, partners, and customers access systems remotely and from anywhere. The attack surface is growing daily, and attackers are increasingly focused on identity — launching phishing, credential stuffing, and social engineering campaigns that can sidestep traditional controls.

Cybercrime is on the increase. In 2024 alone, the UK’s Fraudscape report found a record-breaking 421,000+ cases were filed to the National Fraud Database. Identity fraud linked to mobile services surged by 87%. Attacks are becoming more targeted, more automated, and harder to detect using legacy methods.

Organizations can’t afford to stand still. And Zero Trust strategies that rely on static, user-only data are already outdated.

Vonage Protection Suite delivers the adaptive, intelligence-driven security modern enterprises need. It lets businesses move beyond one-size-fits-all access rules and respond to threats as they happen, using live data from the network itself.

Enabling Zero Trust with Vonage Protection Suite

In a world where attackers exploit both identities and infrastructure, businesses need a security solution that is dynamic, intelligent, and embedded into every interaction. Vonage Protection Suite starts by strengthening the identity and risk signals that sit at the heart of Zero Trust decision-making. This comprehensive set of tools simplifies end-to-end protection, so you can mix and match tools to guard your business against fraud.

• Verify API offers flexible, multichannel 2FA workflows across SMS, voice, WhatsApp, email, and more. The standout feature? Silent Authentication — a telecom-grade capability that passively verifies users by relying on real-time mobile network data. No OTP required, no friction introduced. Users stay secure without ever being slowed down.

• Identity Insights API enriches Zero Trust risk models with dynamic telecom intelligence. It detects signs of fraud, such as SIM swaps, unreachable devices, and mismatched subscriber records. By combining this with enterprise identity and behavioral data, businesses gain a holistic risk view that evolves with every login, transaction, and interaction.

This combination makes continuous, adaptive security possible — deploying the right challenge at the right time, and only when needed. Low-risk users enjoy seamless access. High-risk behavior triggers step-up verification or automatic lockdown. It’s risk-aware security without disruption.

Protecting the communications layer, too

Zero Trust can’t just be about user accounts. The communication channels we rely on, like voice, messaging, and notifications, are increasingly exploited by attackers through traffic pumping, AIT fraud, phishing, non-human identities, and toll scams.

That’s why Fraud Defender plays a critical role in the Vonage Protection Suite. It actively monitors messaging and voice traffic in real time, blocking malicious patterns before they escalate. With customizable controls and global coverage, it safeguards communication workflows that traditional Zero Trust tools aren’t typically built to manage.

Together, Vonage Verify API, Identity Insights API, and Fraud Defender form a unified, intelligent defense that spans identity, access, infrastructure, and interaction. No silos. No gaps.

Use cases across industries

These capabilities aren’t theoretical. Businesses across sectors are already putting them to work:

• Financial services use Vonage Protection Suite to secure high-risk moments like logins, password resets, and financial transactions. These tools validate device ownership and flag anomalies, like recent SIM swaps or unreachable numbers — critical indicators of account takeover attempts. This helps banks and fintech companies protect sensitive data, meet evolving regulatory demands, and maintain customer trust without introducing friction.

• Media and entertainment providers can verify users in real time, stopping account takeovers, fake sign-ups, and bot abuse before they escalate. For example, streaming platforms benefit from seamless identity checks that prevent credential fraud, while game publishers can enforce one-account-per-user policies and block malicious traffic at scale.

• Retail and ecommerce platforms streamline checkout and account creation with Silent Authentication, verifying users in the background via mobile network signals — eliminating the need for manual OTPs. When risk indicators surface, such as mismatched subscriber info or signs of automated bot activity, intelligent step-up verification kicks in. This combination improves conversion rates for genuine customers, while effectively blocking fake accounts and fraudulent transactions.

• Healthcare providers rely on Vonage Video API and messaging channels to deliver secure, omnichannel patient engagement while enabling HIPAA compliance. They layer in real-time verification through Verify and Identity Insight to ensure that only authorized individuals can access or exchange confidential health data. This protects patient privacy and reduces the risk of medical fraud during virtual consultations or digital record access.

Built for scale, visibility, and control

Beyond real-time security, Vonage Protection Suite provides the tools organizations need to implement and manage Zero Trust at scale:

• Unified visibility through Management APIs like Reports, Audit, and Advanced Insights

• Omnichannel documentation that integrates seamlessly into powerful reporting

• Global support and consistent protections across geographies and channels
