We are a payment switch and we deal with cardholder data and information. Our primary goal is to ensure the security of customers' payment data, that they are protected.
Our security maturity is now at a good level compared to the past. To be accepted to drive Visa and Mastercard, you have to pass security assessment audits and we have managed to pass all of them now, for some years.
Apart from our firewall, we have three security tools. We have a NAC, we have a SIEM, and our syslogs.
