In this blog post you’ll learn how protective Adyen’s security measures are and whether the popular platform can be considered safe.

Adyen is likely a safe option for business owners as it has been designed to meet global regulatory requirements. As a platform, Adyen was built with the large enterprise in mind. As a result, it’s responsible for processing billions of transactions every year, and serves some of the world’s largest companies.

What Security Benefits Does Adyen Offer for Merchants?

For merchants, Adyen extends its security support beyond simple payment processing. Merchants using Adyen benefit from advanced fraud prevention technology that stays relevant and keeps up with the latest threats through machine learning.

Machine learning can help you as a merchant work towards a higher acceptance rate of payments while lowering the amount of chargebacks you get from customers.

As a payment processor that handles such a large volume of transactions for global brands, Adyen is well-positioned to identify patterns of fraud, and react to any potential payment downtime quickly.

With a view to helping merchants navigate complex regional regulations, Adyen provides regulatory support to business owners which have to deal with regulations such as Strong Customer Authentication (SCA) in Europe.

Security Considerations for Merchants Using Adyen

While Adyen is generally safe for merchants to use, it might not be suitable for every business type.

Small business owners or early-stage startups may find that the onboarding process is more complex than that of other payment solutions. Given that the platform is so customizable, it could be that you don’t require all the extra functionality if your business is still in the early stages of growth.

In addition, Adyen offers custom pricing, which may not prove as beneficial for non-enterprise businesses.

Is Adyen Safe for Customers?

From the customer’s perspective, Adyen is a reliable payment processor that helps keep their payment information secure and reduces the risk of any unauthorized activity.

Customers rarely interact with Adyen directly, since it’s a payment processor that works in the background, but wherever they might interact with it during checkout or authentication flows, the security standards are high.

How Adyen Protects Customer Data

Adyen protects customer data using a multi-layered security model. The primary goal of this model is to minimize exposure at every stage of the payment process. Adyen achieves this through encrypting sensitive payment details during transmission and using tokenization to replace card data with secure identifiers that bad actors can’t interpret.

There’s also authentication methods including 3D secure which is a multi-step authentication process, designed to reduce the risk of cyberattacks and data theft.

What to Do If You Encounter Security Issues With Adyen

As a customer, if you encounter issues while using Adyen as a payment processor, such as a failed transaction or unexpected charge, your first port of call should be to reach out to the merchant who sold you the goods or service.

As a merchant, you can access Adyen’s extensive knowledge base on their website to find answers to common issues and even take one of their courses on payments, risk, finance and more.

If you need more tailored advice or support as a merchant, you can reach Adyen’s support team through your Customer Area account, where you’ll be able to submit, then track, a help ticket to receive support for your issue.

What Are Adyen's Security Measures?

Adyen has extensive security measures that are designed to meet the needs of high-volume global commerce. As such, it takes a proactive approach to keeping payment processing secure, and can be seen as a reliable option for handling payments.

The payment processor also has extensive risk management protocols which you can benefit from, especially if you’re in an enterprise-level company. For example, you can test risk decisions before going live and compare them against live risk profiles, allowing you to make decisions backed by data and mitigating against risk.

PCI DSS Compliance

Adyen maintains PCI DSS Level 1 compliance, which is the highest standard you can get in the payment industry. To meet this standard, a payment processor must exert rigorous controls around its data storage, access management,m and have effective system monitoring measures in place and regular audits.

Fraud Prevention Tools

Adyen uses machine learning models, which are trained on vast amounts of transaction data, to detect signs of fraudulent activity and prevent malicious attempts to steal sensitive data.

Data Encryption and Protection

The payment processor applies encryption to payments in transit and at rest, making sure that confidential data stays that way. By protecting payments for the duration of their lifecycle, it makes it much less likely that someone can intercept it or steal private data for their own gain.

How Safe is Adyen vs. Competitors?

To better assess how secure Adyen is as a payment processor, it’s a good idea to compare it with a few of its high-profile competitors: Stripe and Paypal.

All three payment processors are popular among business owners and collectively handle trillions of payments every year. As such, they’re all held to high industry and consumer standards, even if they serve different businesses.

Stripe is known as the go-to payment process for developers. It offers strong encryption measures and advanced fraud tools through Stripe Radar. It’s well-known as a safe and reliable payment processor for online-first businesses but relies on third-party acquiring partners in some regions.

PayPal is different from the other two payment processors in that it offers a consumer-facing digital wallet as opposed to a complete backend payment infrastructure. With buyer and seller protection programs, you can rely on PayPal to resolve issues, even if there aren’t as many options for managing omnichannel payments.
