It’s All About Security and Compliance

Complying with government and industry regulations is one of the major concerns nowadays when personal information has become a very valuable asset, and there is literally no industry as saturated with sensitive data and therefore as regulated as online billing and payment sector. Understanding that compliance is an ongoing process, not a one-time event, Dot Transition is ready to be your long-term partner helping you prevent security breaches and theft of payment card data, not just today, but in the future.

Pre-certification and Compliance

Dot Transition expertise covers preparation for PCI DSS / PA-DSS certification and ensuring OWASP compliance:

Open Web Application Security Project (OWASP)

It is the worldwide not-for-profit vendor-agnostic community that produces the most respected guidelines in software security. The main principles are as follows:

  • Defense in depth
  • Positive security model
  • Open design
  • Simple security
  • Intrusion detection
  • Secure defaults

Plastic Card Industry Data Security Standard (PCI DSS) and Payment Application Data Security Standard (PA-DSS)

Represent an actionable framework for developing a comprehensive financial data security process. PCI DSS / PA DSS Compliance can bring major benefits to businesses of all sizes, and includes the following main building blocks:

  • Secure network and systems (regularly monitored and tested)
  • Cardholder data protection
  • Vulnerability management program
  • Strong access control measures
  • Information security policy

Fraud Prevention and Risk Management

In today’s changing world fraud risks are constantly changing. That’s why we invest significant resources continuously to stay ahead of the trends in Risk Management delivering solutions to help uncover hidden trends in large amounts of data to identify fraudulent transactions on the fly. Moreover, understanding that very different risks are associated with different industries, we are ready to develop unique solutions based on industry-specific fraud rules.

Security Testing

When it comes to online transactions, security is the axiom. Dot Transition can help you identify the vulnerabilities of your Billing and Payment solution, emulate the workflow of the attacking side, and deliver and implement expert recommendations on how to protect your system from penetrating attacks. We utilize both Automated and Manual Testing, along with our expertise in building secure online systems, for this purpose.
