The talks at the Presidential Palace were attended by Gen. Wiesław Kukuła, Chief of the General Staff of the Polish Armed Forces, and Bartosz Grodecki, head of the National Security Bureau (BBN).
Speaking to reporters afterwards, Kosiniak-Kamysz described the meeting as "very constructive."
He said a shared sense of purpose on security was needed "at all centres of power" – in government, parliament and the presidency – particularly "in these difficult times."
The talks covered current events and the security situation, with cooperation with the United States a particular focus.
Kosiniak-Kamysz stressed there were no differences between the government and the president over efforts to establish a permanent US military base in Poland.
He praised Nawrocki's relationship with President Donald Trump, adding that preparing and funding the infrastructure needed to host American troops would be the government's responsibility.
The Polish defence minister also said the meeting touched on intelligence Nawrocki had received on Thursday from CIA Director John Ratcliffe.
Kosiniak-Kamysz is due to meet US Defence Secretary Pete Hegseth in Washington next week.
Talks are expected to include the proposed US military presence in Poland and the security situation linked to Russia's war in Ukraine.
The Friday meeting came after a series of recent incidents involving drones near the Polish border with Ukraine.
On Thursday, Prime Minister Donald Tusk warned that "serious events" were the most likely scenario for the coming months.
He said intelligence assessments indicated that Russia could seek to carry out hybrid attacks involving drones and missiles against NATO countries supporting Ukraine, including Poland.
