In a world where artificial intelligence and digitalization are reshaping financial services, one priority stands out: protecting innovation without slowing it down. With this vision in mind, Criticalcase participated in the 2025 Digital360 Awards, presenting a cutting-edge project in the field of cybersecurity applied to AI and APIs.
The project, developed for a prestigious international financial institution, was designed to address a concrete yet complex challenge: how to secure new strategic initiatives — such as public chatbots, AI assistants for contact centers, and API governance platforms — that, while driving growth, inevitably expand the organization’s attack surface.
The challenge: protecting transformation without slowing it down
Generative AI models and conversational systems introduce entirely new risks. Prompt manipulation (prompt injection), data leakage, API abuse, and service saturation attempts are real threats that require a modern, flexible, real-time security approach.
On stage at the event, our VP of Sales, Alessandro Zoncu, explained how we tackled this challenge by presenting a solution that not only protects but empowers innovation safely.
The solution: a Distributed Security Layer at the Edge
Our response was to design a Distributed Security Layer for AI and APIs deployed at the Edge — as close as possible to the end user. This intelligent shield governs the entire AI interaction lifecycle (“input → model → output”) and intervenes in real time to neutralize threats before they reach the client’s core systems.
The pillars of our architecture are:
- AI Firewall: inspects and blocks prompt manipulation attempts, prevents data leakage, and, when necessary, “rewrites” AI responses to mask sensitive information (such as personal or financial data) before it is displayed to the user.
- Continuous API Security: through automatic discovery, we maintain an always-updated catalog of all exposed interfaces — including “shadow” APIs not yet registered. We verify their configurations and protect them from abuse, attacks, and credential theft.
- Performance and Continuity: security must not become a bottleneck. Our solution ensures low latency and high availability, guaranteeing a seamless user experience even during traffic peaks.
Tangible results: from risk to competitive advantage
Implementing this security layer has enabled our client to achieve measurable benefits:
- Safer AI releases: the ability to launch new AI-based services with verifiable “guardrails” increased trust among users and internal stakeholders.
- Smooth user experience: response times remained low and service stable, even under pressure, with AI outputs that were consistent and cleansed of sensitive data.
- More efficient operations: with unified telemetry and adaptive policies, security teams can detect and resolve incidents faster, with fewer false positives and more focused investigations.
Being selected to present this case at the Digital360 Awards makes us proud and motivates us to keep advancing. In an era where companies are seeking reliable partners to adopt emerging technologies, Criticalcase stands out as a trusted reference point for organizations that want to protect their digital transformation — without compromise.
