We are your most trusted source for robust, reliable, and always available payment testing tools & simulators.

For more than 30 years Paragon has been providing innovative solutions to some of the largest and most sophisticated financial services organizations in the world, including banks, card brands, networks, processors, ATM deployers, payment gateways, fintechs and retailers.

Let us know about your most pressing testing challenges and a Paragon product specialist will walk you through our portfolio and look how we can help optimize your payment testing operations:

Testing Automation: Payment systems have become too complex and change too quickly for any organization to risk new releases or deployments without the extensive use of automated test execution and validation.
ATM Testing Optimization: Virtualizing your ATM fleet enables 24 x 7 remote access to your ATM testing environment, expands test coverage and facilitates data driven automation.
Certification Systems: Improve time to value by cutting onboarding and certification times for new clients and members from weeks and months to days.
End-to-End Testing: Automate end-to-end issuer or acquirer transaction flows for ISO and ATM messages, including EMV contact and contactless processing.

Performance Testing: Push your payment systems to the limit to identify and resolve issues before they cause an outage or a negative consumer experience.
API Integration: Paragon offers published APIs to help integrate your payment testing environment with other enterprise systems, such as a CI/CD pipeline.
