NIS2 for Financial Services: Professor Kai London on Turning Compliance Into Competitive Advantage
By the Swiss Times Business Desk
For financial institutions, the tightening web of cyber regulation can feel like an ever-growing tax on doing business. Professor Kai London, a senior CISO and board advisor, urges leaders to see it differently. “Resilience regulation is not a tax,” he says. “It is a specification for the trust your customers already expect. The institutions that treat it as an operating standard, rather than a compliance chore, turn it into an advantage.”
“Every serious financial institution is being asked the same question by regulators, partners and clients: can you keep running, and can you prove it? The ones who answer confidently will win the business the others cannot.”
A converging rulebook
London notes that financial firms increasingly sit at the intersection of several resilience regimes — sector-specific operational-resilience rules, the broader network-and-information-security directives, and data-protection law. Rather than treat each as a separate project, he argues for a single resilience operating model that satisfies them together. “The requirements rhyme,” he says. “Keep critical services running, detect and report incidents quickly, manage third-party risk, and prove it all. Build once, comply many times.”
The four capabilities that matter
Beneath the legal language, London distils the obligations into four operational capabilities. First, know your critical services and their maximum tolerable downtime. Second, be able to detect, contain and report an incident within tight, regulator-set timeframes. Third, understand and manage the third parties and platforms you depend on — including the systemic risk of everyone relying on the same few providers. Fourth, test your resilience under realistic, threat-led conditions rather than assuming it. “If you can do those four things and evidence them,” he says, “most of the regulation takes care of itself.”
Third-party risk is the sharp edge
London is emphatic that concentration and supply-chain risk is where financial resilience is most fragile. Modern banking runs on a shared foundation of cloud platforms, payment rails and technology vendors. “Your resilience is only as strong as the provider you cannot live without,” he says. Regulators have noticed, which is why oversight of critical third parties has become a central theme. “Boards must be able to answer not only ‘are we resilient?’ but ‘are our critical suppliers, and what happens if one fails?’”
Management accountability is the point
The feature of the new regimes London stresses most is personal accountability. Senior management is expected to own, approve and oversee cyber-risk measures — and can be held responsible for failures. “This is the deliberate design of the regulation,” he says. “It moves cyber resilience from a technical concern the board hears about, to a governance duty the board answers for. That changes the conversation entirely.”
From cost centre to differentiator
London's central reframing is commercial. In a sector built on trust, demonstrable resilience is a selling point. Corporate clients, counterparties and regulators increasingly demand evidence of operational robustness before they will do business. “An institution that can walk in and prove it will keep running through a crisis has an edge over one that can only promise,” he says. “Resilience you can evidence wins mandates.”
Where to begin
For firms still building the muscle, London recommends starting with an honest map of critical services and the dependencies beneath them, then hardening incident detection and reporting to meet the timelines, and finally testing the whole thing under pressure. The interim and fractional CISO model, he notes, is increasingly used to bring senior resilience expertise into mid-sized institutions quickly, without the delay of a permanent executive search. “You do not need a large team to get this right,” he says. “You need the right senior hands to set the standard and prove it works.”
For a financial community whose currency is confidence, London's message lands cleanly: the regulation everyone is bracing for is, in the end, a description of the resilience customers already assume you have. Meet it as a standard, prove it, and it becomes a reason to choose you.
