The New Frontier of Payment Security: Protecting the Entire Trust Cycle
By Bruno Capelas, Sales Director of CyberWatch
Payments have become faster, simpler and increasingly embedded in our everyday lives. This evolution has brought greater convenience, but it has also changed the way risk emerges. A fraudulent transaction can start long before anyone clicks “pay”, with a phishing message, unauthorised access to an account or a compromised device. Protecting a payment can no longer mean focusing solely on the transaction itself. It means understanding who is initiating it, the context in which it takes place, and the wider chain of trust that makes it possible.
Trust starts before the transaction
Attackers are increasingly targeting people. Social engineering, identity theft and compromised devices can make fraudulent activity look legitimate. Artificial intelligence is making these attacks more convincing and increasingly personalised. But the same technology can also strengthen defence, helping organisations identify patterns, detect anomalies and recognise threats earlier. The goal is not to replace human judgement, but to equip teams with better intelligence, sooner, so they can make better informed decisions.
Context determines the level of protection
Even with strong prevention measures in place, mistakes and unexpected situations will happen. Security must therefore be able to adapt its response to the level of risk.A familiar transaction should be able to happen seamlessly. When an operation deviates from expected behaviour, it may warrant an additional layer of verification. Making that distinction requires context: who is performing the operation? Which device are they using? Is the transaction consistent with their usual behaviour?
Strong authentication, digital certificates, biometrics and behavioural analysis can help answer these questions by combining multiple signals, rather than relying on a single credential to establish trust.The objective is simple: increase protection when risk increases, without turning security into a barrier to the user experience.
Trust depends on the entire chain
But even an organisation that knows its customers and operations well depends on other entities. Banks, merchants, fintechs, technology providers and service providers are part of an increasingly interconnected chain. A vulnerability in one of its elements can affect the others. This is why third-party risk management, an understanding of critical dependencies and preparedness for coordinated responses are also part of payment security. DORA and NIS2 reflect this broader focus on risk management, business continuity and organisational resilience.
Preparing for response, not just prevention
No system is completely immune to incidents. When a threat gets through the initial layers of defence, what matters is how quickly it is detected, how effectively the organisation responds and how quickly it can recover. Monitoring, threat intelligence and detection technologies are essential. But technology alone is not enough. Consistent outcomes depend on clear processes, well prepared teams, regular exercises and effective continuity mechanisms. In an ecosystem where payments happen in seconds, the ability to respond must keep pace with the speed at which threats evolve.
Protecting the trust cycle
Payment security starts before the transaction and does not end when it is completed.
Identity, fraud, cybersecurity and resilience are increasingly interconnected. An attack can begin in the digital environment, exploit an identity and ultimately result in a fraudulent transaction. Equally, a vulnerability affecting a third party can undermine trust across the wider ecosystem.
Protecting payments therefore requires an integrated approach: preventing threats, detecting them early, responding effectively and recovering quickly, while keeping the experience as seamless as possible whenever the level of risk allows it.
Ultimately, the challenge is no longer simply to protect each transaction.
It is to protect the entire trust cycle that makes the system work.
