What Our Clients Say...


Paragon software allows us to do quicker and more accurate testing.  We can set up as many test scripts as we want and use them multiple times as needed.  We can also easily make updates to our ATM screens and test the entire transaction flow prior to uploading the configuration files to the ATM.

Vice President
Regional Bank A, North America

We can review the ATM configuration flow and exclude all unnecessary states and screens so we don’t load them, which has saved us time and money.  We can also quickly test how numerous response codes are seen on the ATM screen.

Department Head
ATM Processor, Europe

Paragon’s ATMulator helped us quickly develop and implement a new enhanced ATM configuration, and FASTress provided the opportunity for us to determine, prior to production deployment, if our transaction authorization host could meet our processing needs.

Program Manager
Tier One Bank A, North America

Instead of conducting all of our testing directly with member organizations, we use Paragon to simulate and test these interfaces which has significantly reduced our testing time.  The QA team uses Paragon software to execute their test plans and the developers are starting to use the products for their technical tests.

QA Manager
ATM Network Operator, Latin America

Paragon solutions save us time and money by allowing our developers to test changes to our ATM processing at their workstation. Paragon has always been helpful and seems more like a partner than a vendor.

Programming Manager
Regional Bank B, North America

FASTest is a strong product which does as it advertises. It’s easy to use and bulletproof once the transactions are built. We use this application daily and rely on it heavily to run comprehensive regression tests.

QA Manager
Global Merchant Acquirer

We place great value on our relationship with Paragon who has always proven to be responsive to our company's needs!

Vice President
Third Party Processor, North America

Paragon enabled us to significantly reduce the number of test hours with our service provider. As a result, we have cut our outside testing costs and are using our time more efficiently.

Senior Vice President
Regional Bank C, North America

Stress testing is a mandatory requirement for all our mission critical transactional systems.  We chose Paragon because we believe they offered the best quality/price ratio.

Program Manager
Tier One Bank B, North America

By combining our expertise with Paragon’s proven ePayment performance testing solution, we were able to prove our customer’s system capacity in only one month. We are committed to providing our customers with the highest quality solutions to meet their business objectives and look forward to partnering with Paragon on future engagements.
