Of course it's not.
There is no specific word in Polish for "firewall". That's why they gave the English word "firewall" and Polish description-explanation what it is . All three parts, "program zabezpieczający sieć i system", "zapora sieciowa" and "firewall" have exactly the same meaning. I don't think there's need to translate all of them to English as "firewall" alone is clear to all English speakers.
