To manage their internet payments, many businesses rely on payment processing firms. However, relying solely on a third party might cause organizations to undervalue the dangers and needs associated with payment gateway security, leaving them vulnerable to data breaches and cybercrime. When businesses evolve, such as by expanding operations or switching to a subscription-paying model, this problem simply gets worse.
Global Economic Crime and Fraud Survey 2022 by PWC indicated that 52% of businesses with annual global revenues over $10 billion had suffered fraud in the previous 24 months, with 18% suffering a loss of more than $50 million in the most upsetting instance.
Smaller businesses with annual revenue under $100 million were affected by fraud in 38% of cases; of those, 22% had financial losses totaling over $1 million.
To protect your organization, online payment security must be given high importance. Discover the five security elements that every business requires for a payment gateway in the following paragraphs.
A payment gateway is what?
An e-commerce merchant service known as a payment gateway gathers payment information from clients in order to authorize a transaction and confirm the validity of the payment. Between the merchant's website, the customer's financial institution, and the merchant's financial institution, payment gateways read, encrypt, and send data.
Why is the security of payment gateways important?
To secure your business and the personal information of your clients, payment gateway security is essential. Security lapses, fraud, and compliance infractions are all expensive errors that put your brand's reputation in danger in addition to costing you hard-earned money.
A breach or theft of cardholder data may result in fines of up to €20 million or 4% of annual global revenue, whichever is greater under the General Data Protection Regulation (GDPR) of the European Union.
Additionally, companies that violate the Payment Card Industry Data Security Standard (PCI DSS) may be fined $5,000 to $100,000 per month for non-compliance by payment providers.
Companies must, therefore, be prepared to offer a secure buying experience as more clients turn to e-commerce for their shopping needs.
Top 5 security features for payment gateways
The basis of developing a culture of data security is continuous learning, therefore it's imperative that your staff stay current on the most recent safety measures and frequently assess if it's time for an upgrade. The five payment gateway security elements listed below are requirements in the current corporate environment.
Compliance with PCI DSS
Payment Card Industry Data Security Standard (PCI DSS) requirements must be followed by any business that accepts credit or debit cards for payment. The PCI DSS's primary function is to give organizations a standardized approach to stringent, secure transaction operations while maintaining a positive customer experience.
In addition to helping, you avoid fines and enhance your standing with payment processors, maintaining PCI compliance also strengthens your security measures against data breaches and credit card theft. There are 12 major requirements in the PCI DSS, which are further divided into 78 base requirements and 400 test processes. The illustration below outlines the 12 essential requirements:
Depending on their size, companies must conform to various levels of compliance. Businesses are categorized by the PCI according to the volume of transactions they handle annually on a four-level scale:
Level 1: Annual card transactions exceeding 6 million.
Level 2: 1-6 million card transactions per year.
Level 3: Annual card transactions range from 20,000 to 1,000,000.
Level 4: 20,000 card transactions per year.
Although it is a requirement that all reputable processing providers offer PCI-compliant services, it is still worthwhile to learn more about the PCI DSS because non-compliance will have serious consequences for your company. Make sure the payment processor can manage credit card processing, transaction history, and credit card data management while adhering to the PCI DSS when choosing which one to invest in.
the TLS and SSL protocols
Sensitive data is protected end-to-end throughout the internet connection between the browser and the server thanks to the Secure Sockets Layer (SSL) and Transport Layer Security (TLS) protocols. These safety precautions guarantee the safe transmission of consumer information gathered by a payment gateway.
The "TLS/SSL handshake," which is the name of the encryption procedure, is described in the following manner:
A public key and a private key are used in every TLS/SSL certificate. A secure TLS/SSL encrypted connection is detected when a customer accesses the website by communicating with their server and web browser. To establish a secure connection and create a special session key, the website server exchanges its TLS/SSL certificate and public key with the user when the web browser directs to the website. The browser verifies that the TLS/SSL certificate's issuer (Certificate Authority) is one it recognizes and that the certificate is valid and not expired, revoked, or otherwise suspected.The session key is transmitted by the browser, and it is decrypted by the server using its private key.The encrypted session is then initiated by the server by returning an encrypted acknowledgment.With the session key, the server and browser can now encrypt all transferred data, establishing a secure session that strengthens the privacy, integrity, and security of all shared data.If you've ever been to a website with an HTTPS URL or a lock icon next to it, you've come across TLS/SSL encryption. These symbols denote the website's TLS/SSL certification and the confidence your clients can have in your business when it comes to their financial data.
3D Secure
A security feature called 3D Secure (3-domain structure) or payer authentication solves the problem of fraud in online debit or credit card transactions. At checkout, customers must complete an additional stage of card issuer verification, using all three payer authentication domains:
The domain of the seller or buyer issuing domain The area of interoperability The most recent version, 3D Secure 2, offers a variety of password-free methods of verification, such as: Using two distinct authentication methods, such as a username and password combination and a phone, is known as 2FA (two-factor authentication).Fingerprint, face, or voice recognition are examples of biometric identification.Risk-based authentication is a flexible method of authentication that necessitates various protocols according to the risk profile of the customer.Tokenization
Sensitive data is replaced with a token, a string of randomly generated digits, to secure consumer payment information. For good reason, the PCI DSS encourages the use of payment tokenization.
The principal account numbers kept outside the merchant's server can be replaced exactly with tokens. Sensitive information does not have to be stored by the merchant, safeguarding both the merchant and the client from fraud.
In the event of a breach, this additional layer of security renders confidential information meaningless and useless. Hackers would be ineffective if they managed to access the tokens because they wouldn't be able to decipher them.
Address Verification Service
AVS, which verifies addresses, is yet another approach that is frequently used to stop credit card fraud. AVS will verify that the billing address entered by the consumer matches the address that is on file with the credit card company. The transaction will be accepted if it matches.
AVS is a protocol that has the potential to reduce chargebacks. Verifying the information provided by the cardholder throughout the checkout process can assist in identifying unusual transactions and safeguard the business before fraud happens.
