The rapid evolution of cybersecurity in the financial sector was the focus of a recent episode of the Pair Program podcast, hosted by Tim Winkler, a serial entrepreneur, and Mike Gruen, a technologist and engineering leader. The podcast, published on January 21, 2025, featured Jacques Boschung, CEO of Halborn, and Sandip Wadje, Managing Director and Global Head of Emerging Technology Operational Risks & Intelligence at BNP Paribas. The conversation unpacked the challenges and innovations in traditional IT and blockchain security, offering a glimpse into the future of digital finance.
The State of Cybersecurity in Banking
Sandip highlighted the unique challenges traditional banking systems face, including the escalating threats of ransomware, phishing campaigns, and geopolitical disruptions. He noted that many of these vulnerabilities stem from the foundational design of the internet, which prioritized collaboration over security. As banks scale their IT infrastructures, integrating new technologies often exposes fault lines in legacy systems.
The internet was not designed to be secure; it was designed to be collaborative - Sandip Wadje
Key Takeaway: Traditional banking systems are grappling with the complexities of modernizing their infrastructures while retrofitting security measures into inherently vulnerable systems.
Blockchain’s Transformative Potential
Jacques provided a compelling vision of blockchain as a driver of the third wave of digital transformation in banking. He emphasized three key use cases:
Central Bank Digital Currencies (CBDCs): Revolutionizing monetary systems.
Security Issuance: Streamlining the issuance and trade of financial instruments.
On-Chain Clearing & Settlements: Enhancing efficiency and mitigating risks in financial transactions.
Jacques underscored that while blockchain offers transparency, immutability, ensuring that transactions cannot be tampered with, thereby enhancing trust and security, and efficiency, it also presents unique challenges. Unlike traditional systems, where responses to breaches can take hours, on-chain vulnerabilities can result in immediate financial losses. This necessitates a proactive and decentralized approach to cybersecurity: the “secure by design” approach.
In the new digital transformation, security is everything. Because unlike in a classical perimeter, where between detection and response you have a little bit of time (...) onchain, if something is happening, your cash is gone. So we have a real “holdup” type of robbery situation which is really unique to that new digital real and that requires for those decentralized systems a totally new way of thinking about cyber and risk - Jacques Boschung
Key Takeaway: Blockchain’s potential lies in its transparency, speed, non-tampering guarantee, and efficiency, but its real-time nature demands robust and innovative security measures.
Halborn’s Role in Securing Digital Finance
At Halborn, blockchain security takes center stage. Jacques elaborated on the company’s multifaceted approach:
Smart Contract Audits: Ensuring the integrity of the code that underpins decentralized apps.
Secure-by-Design Principles: Combining Web2 and blockchain security to create robust, scalable systems.
Blockchain Vulnerability Scoring System (BVSS): A pioneering tool that assesses blockchain security, helping organizations identify and mitigate risks proactively.
Seraph - Policy Enforcement Tools: Introducing centralized controls within decentralized apps, to enhance security and compliance but also the ability to simulate transactions on-chain
Secure by design combines upfront both the web2 (...) and blockchain aspect of cybersecurity , because you always have a combination (...) of onchain and offchain systems - Jacques Boschung
Key Takeaway: Halborn’s innovative security solutions are bridging the gap between traditional financial systems and blockchain, enabling secure adoption of this transformative technology.
The Road Ahead: Quantum and Beyond
The discussion also touched on emerging technologies like quantum computing and AI. Jacques warned of the potential risks quantum advancements pose to current encryption standards, urging the industry to prepare for a post-quantum security landscape. Meanwhile, Sandip highlighted AI’s role in industrializing risk assessments and revolutionizing threat detection, particularly in identifying geopolitical and supply chain vulnerabilities.
I think people are going to miss the tipping point on quantum (...) because they didn't see ChatGPT coming in 2022, and we will have a similar moment with quantum where people think that it’s 10 years away and then - boom! - the tipping point comes faster than you think and you're not prepared for it - Sandip Wadje
Key Takeaway: The intersection of blockchain, AI, and quantum computing represents the next frontier in cybersecurity, requiring a forward-thinking and collaborative approach.
