Data protection standards

The Payment Card Industry Data Security Standard (PCI-DSS) is a set of comprehensive requirements that all businesses handling credit and debit payments must comply with. These standards help reduce the likelihood of identity theft, fraud and unauthorized transactions. In addition to industry and regulatory encryption requirements, our Information Security Policies and Controls are reviewed by independent third parties. We hold certifications under many programs and standards, including the Visa Cardholder Information Security Program, Mastercard Site Data Protection Program and the American Institute of Certified Public Accountant’s Statement on Standards for Attestation Engagements No. 18 SOC1 and SOC2.

PayPal has partnered with HackerOne to engage the security research community to help make our products and services even more secure. If you're a security researcher and have found a vulnerability in a PayPal product or service, alert us to your discovery and you can earn a bounty. Get details about our Bug Bounty Program
