KEY FACTS: ZERO-TRUST PAYMENT SECURITY
• 40 % of financial organisations reported more frequent insider threats in 2024.
• Zero-trust requires continuous verification at every step of payment transactions.
• Payment processing involves multiple layers: processors, banks, and card networks.
• Hardware-based encryption enables faster authentication without compromising security.
• Cloud-native architecture helps scale security enforcement without introducing latency.
• Quantum computing threatens current cryptographic standards used in financial transactions.
This continuous validation typically relies on certificate-based authentication and hardware security modules that safeguard encryption keys.
Mitigating transaction speed challenges The critical question becomes: how do financial organisations maintain payment speed while implementing such rigorous security measures?
Innovative approaches are emerging to resolve this apparent contradiction.
Raluca reveals how leading companies balance these competing priorities:
“ Companies mitigate the transaction speed issues in zero-trust networks by using automated risk assessments to pre-validate trusted users and devices.” This proactive validation represents just one strategy in an evolving toolkit.
Other approaches include“ offloading security checks to the background, leveraging hardware-based encryption for faster authentication, and implementing adaptive access controls”.
This last element – adaptive security – proves particularly valuable as it“ scales security measures based on real-time
