Gawkowski, who also serves as a deputy prime minister, said using a wider range of suppliers and open-source software could help limit the risk.
Poland's Ministry of Digital Affairs is working on introducing such tools in public administration, and a competition to pilot them in local government is due to begin soon, Gawkowski said.
Under the initiative, solutions that prove effective would eventually be made available across the public administration system.
Gawkowski said open-source software would not only cut costs but also strengthen the state's "digital sovereignty."
