FinTech & Security.

In the financial world of 2026, a single unverified message can end a customer relationship. As digital banking and mobile wallets become the primary way we manage our lives, the "communication channel" has become the new frontline for cybersecurity. For FinTechs, the challenge is twofold: you must protect your customers from increasingly sophisticated fraud (like AI-powered phishing), and you must do it without making the user experience so difficult that they abandon your app.
At Focus Mobile Ltd, we help FinTechs turn security into a competitive advantage using Verified SMS and Encrypted Chat.
1. The 2FA Evolution: SMS vs. WhatsApp Two-Factor Authentication (2FA) is the bedrock of FinTech security. But in 2026, "one size" no longer fits all.
SMSLeopard for Universal Reach: SMS remains the only channel that works on every single phone, even without data. It is the essential "failsafe" for transaction alerts and OTPs (One-Time Passwords). By using a dedicated, branded Sender ID through SMSLeopard, you ensure customers recognize your code instantly, reducing the risk of them falling for "smishing" (SMS phishing) from random numbers.
ChatSasa for End-to-End Encryption: For high-stakes interactions—like sharing a proof of payment or updating KYC (Know Your Customer) documents—WhatsApp via ChatSasa offers a layer of end-to-end encryption that standard SMS cannot. The "Green Tick" verification on WhatsApp provides an immediate visual signal that the conversation is secure and official.
2. Proactive Fraud Prevention (The "Human-First" Alert) Trust is built in the moments between transactions. 2026's leading FinTechs use a Hybrid Communication Model to stop fraud before it happens.
Real-Time Anomaly Alerts: If a login occurs from an unrecognized device, an automated SMS alert is sent instantly.
The Verified Chat Resolution: Instead of forcing a customer to wait on a 20-minute phone call to verify a transaction, ChatSasa allows them to jump into a secure, authenticated chat. They can verify their identity using biometrics on their phone and resolve the alert in seconds.
3. Compliance as a Service In the regulatory landscape of 2026, "I sent the message" isn't enough. You need to prove it.
Both SMSLeopard and ChatSasa provide the audit trails required for financial compliance. From delivery timestamps to consent logs (opt-ins and opt-outs), our platforms ensure that your communication isn't just secure—it’s defensible.
The Bottom Line: Security is the Experience
In 2026, customers don't just want a fast app; they want a safe one. By unifying your security alerts and verified communications into a single, reliable flow, you aren't just protecting balances—you’re protecting your brand's reputation.
