Speaking as part of the panel, which was chaired by CNN presenter Clarissa Ward, Rabbi Janner-Klausner argued that a better response would have been to acknowledge antisemitism and lay out his government's response.
She said that practical responses were needed to deal with the rise in antisemitism across Europe.
She added more should be done to build relationships by inviting non-Jews for Friday night dinners and opening up conversations when antisemitic views are aired.
She said one way of tackling the problem was working with non-Jews to help educate them about the Jewish community and what antisemitism is.
She said "difficult conversations on a national scale" were needed and praised organisations JPR and CST, whose research was cited throughout the meeting.
Mr Szalay-Bobrovniczky's brother Vince Szalay-Bobrovniczky, a close all of Mr Orbán hit the headlines in February when the Board published his angry email attacking Board President Marie van der Zyl for speaking out against antisemitism in Hungary.
In his letter, he said he was "extremely sorry for the Jews that you pretend to represent", claiming her accusations of antisemitism were "a simple lie" and telling her to "mind your own business".
