CONTENTS

Further to Alarum Technologies Ltd.’s (the “Registrant”) Report of Foreign Private Issuer on Form 6-K furnished to the Securities and Exchange Commission on July 22, 2026, regarding the Registrant’s receipt of a motion seeking the discovery and inspection of certain Registrant documents (the “Initial Discovery Motion”), on August 10, 2026, the Registrant was formally served with an additional motion filed in the Economic Department of the District Court in Tel Aviv pursuant to Section 198A of the Israeli Companies Law, 5759-1999 (the “Israeli Companies Law”), concerning the similar underlying matters as the Initial Discovery Motion (the “Additional Discovery Motion”). The Additional Discovery Motion lists the Registrant’s subsidiary, NetNut Ltd., as another respondent.

The court set a timeline for the Registrant’s answer and a response to the Registrant’s answer, and scheduled a hearing on the Additional Discovery Motion for December 14, 2026.

In addition, further to the Registrant’s Report of Foreign Private Issuer on Form 6-K furnished to the Securities and Exchange Commission on July 22, 2026, regarding the motion to certify a claim as a class action filed in the Economic Department of the District Court in Tel Aviv, Israel, against the Registrant, and some of its officers (the “Israeli Class Action Motion”), the Registrant has subsequently become aware of, but has not been served with, a class action complaint filed on August 5, 2026 by Omer Cygler in the United States District Court for the District of New Jersey against the same defendants named in the Israeli Class Action Motion.

The Registrant is reviewing both proceedings together with its legal advisors and intends to defend itself vigorously. The Registrant will provide updates regarding these matters if and when required in accordance with applicable law.

This Report of Foreign Private Issuer on Form 6-K (the “Report”), including its exhibit, is incorporated by reference into the registration statements on Form S-8 (File Nos. 333-233510, 333-239249, 333-250138, 333-258744, 333-267586, 333-274585, 333-285941 and 333-296294) and Form F-3 (File No. 333-283429) of the Registrant, filed with the Securities and Exchange Commission, to be a part thereof from the date on which this report is submitted, to the extent not superseded by documents or reports subsequently filed or furnished.
