In today’s digital age, online transactions have become an essential part of our daily lives. With the rise of e-commerce, businesses need to ensure that their online payment processing systems are secure, efficient, and user-friendly. This is where payment gateways come into play.

Payment gateways act as a bridge between the merchant’s website and the payment processor, ensuring a seamless and secure transaction experience.

• Network Security: Payment gateways implement robust network security measures, including firewalls, intrusion detection systems (IDS), and network segmentation.
• Access Control: Payment gateways restrict access to payment card data by implementing strong access controls, authentication mechanisms, and user authentication protocols.
• Two-Factor Authentication (2FA): Payment gateways require users to provide two forms of identification, enhancing access control and mitigating the risk of unauthorized account access.
