Fresh off the heels of the AI, Cloud & Cybersecurity Congress 2025, The Digital Banker had the opportunity to sit down with Sateesh Reddy, Group Chief Technology Officer at Tonik Bank, the Philippines’ first challenger bank. In a fast-moving fintech landscape, Reddy shares insights on the evolving role of technology in digital banking and what’s next on the innovation roadmap. Here’s what he had to say.
How is Tonik Bank leveraging artificial intelligence (AI) to future-proof banking in the Philippines?
“At Tonik, we see AI not just as an efficiency play—but as a core enabler of inclusive, intelligent banking. We’re building an AI-native financial platform that understands our customers better than any legacy bank can and adapts in real time to their needs.
We’ve rolled out AI-driven credit scoring models that go far beyond traditional bureau data which has data on less than 30% of the population. By analysing behavioural patterns, payment history, and even device signals, we’re able to responsibly extend credit to millions of Filipinos who would otherwise be invisible to the financial system. More than 4 in 5 of our borrowers are accessing formal credit for the first time, which is a powerful testament to financial inclusion through data.
On the customer experience side, we were the first in the country to launch a GenAI-powered chatbot that now handles the majority of our inbound queries. It’s fast, contextual, and deeply integrated into our stack—improving service response times while keeping operational costs flat.
We’re also deploying AI in predictive ways—forecasting customer churn, identifying upsell opportunities, and personalizing financial journeys end-to-end. It’s about anticipating needs before they’re even voiced.
But more importantly, AI is not an overlay at Tonik—it’s built into how we operate. From fraud detection using biometric telemetry to security alerting and real-time cloud infrastructure tuning, our entire platform is infused with machine intelligence.
That’s how we future-proof Tonik—not just as a digital bank, but as a smart, scalable ecosystem that learns and evolves with every transaction.”
In the face of increasingly sophisticated cyber threats, how is Tonik Bank putting measures in place to safeguard its customers from these evolving threats?
As the first licensed digital bank in the Philippines, security is at the core of everything we do. In a landscape of evolving cyber threats, Tonik is built on Zero Trust Architecture which enforces strict identity verification, least privilege access. This eliminates implicit trust and safeguards assets through MFA (multi factor authentication), and behaviour-based controls.
With fraud prevention models, we monitor transactions in real-time and identify anomalous patterns that could indicate fraudulent activity.To prevent unauthorised access, we’ve embedded biometric identity verification into our core onboarding and login flows. It’s more than just facial recognition—it includes liveness detection and device telemetry to guard against account takeovers and synthetic IDs.
We’re fully encrypted across all transmission layers, and every deployment goes through automated security scans, code reviews, and third-party penetration testing.
Tonik also follows a Defense-in-Depth security strategy, which includes continuous monitoring, rigorous vulnerability assessments, and the latest threat intelligence to stay ahead of potential attacks. Our SOC (Security Operations Centre) is operational 24/7 to ensure we can swiftly respond to emerging threats and uphold the security of our clients.
What role does cloud technology play in scaling and increasing the efficiency of Tonik Bank’s services? What approach did the bank use when selecting cloud partners?
Cloud is not a backend choice for us—it’s our operating model. Tonik was born cloud-native. Every system, from our core banking engine to KYC, fraud detection, and analytics, runs in a fully containerized, orchestrated cloud environment. This is how we move fast, stay lean, and scale without friction.
The ability to roll out new features daily, scale infrastructure on demand, and automate everything from testing to release is only possible because of our cloud-native foundation.
When we evaluated cloud partners, security, scale, and ecosystem maturity were non-negotiable.
Tonik operates on a purpose-built multi-cloud architecture AWS powers our scalable core stack, while GCP complements with data workloads and ML training—enabling cost-performance balance and geo-resilience.
Tonik isn’t just in the cloud—we’re engineered for it. Our cloud-native architecture fuses fintech-grade agility with the resilience, security, and compliance of a regulated bank—enabling us to serve millions with speed, safety, and scale.
Looking ahead, which emerging technologies do you think will have a significant impact on the digital banking landscape? How is Tonik Bank preparing for these developments?
The digital banking landscape is being reshaped by a new wave of emerging technologies, and at Tonik, we see this as a massive opportunity to leap ahead—not just keep pace.
One of the biggest shifts is the rise of agentic AI systems. These are autonomous AI agents capable of handling complex, repetitive workflows across operations, support, and risk—something we’re already piloting internally to reduce manual load and improve scalability, with humans in the loop for oversight.
Second, AI-driven personalisation and credit modeling will redefine how banks serve the underbanked. We’re deploying ensemble-based credit scoring models that use behavioral, device, and telco data to assess creditworthiness for customers with no formal credit history. These models are hosted on Vertex AI and retrained continuously using production drift signals.
Security is another area where we expect transformation. With the increasing use of AI, Zero Trust security models are no longer optional. Tonik is investing heavily in this area—embedding LLM guardrails, enforcing endpoint controls, and sandboxing agent behavior to ensure both compliance and resilience.
Finally, we’re also preparing for the long-term potential of open banking and programmable finance—building on our modular API stack to enable seamless fintech integrations and exploring blockchain use cases around digital identity and cross-border payments.
In short, Tonik isn’t waiting for the future to arrive—we’re engineering toward it, with a cloud-native, AI-secure, and API-first foundation that allows us to serve millions with the agility of a fintech and the stability of a regulated bank.
