October 7, 2026 17:47 CEST Scheduled - Phishing simulation landing pages now use HTTPS to support compatibility with modern browsers, ensure reliable access to the Most Teachable Moment page, improve reporting accuracy for phishing interactions, and align with current security standards. Depending on their configuration, some customers may need to update their infrastructure to use the new domains: Customers using IP/DKIM whitelisting do not need to make any changes. Customers who generated a domain list in the Control Panel must regenerate the list as soon as possible and update their infrastructure. If the new domains are not added, simulation statistics may be inaccurate, emails may not be delivered, or autoclickers and other filters may intercept emails.

September 16, 2026 15:16 CEST Scheduled - At Hornetsecurity, we’re continually enhancing the security of the Hornet.email platform to keep pace with evolving best practices. As part of this ongoing work, we’re introducing a change that may affect some of your users’ accounts. Users who regularly sign in to Hornet.email will not be affected - no action is needed for them. For any of your users who haven’t logged into Hornet.email since April 28, 2026, their existing password will need to be reset the next time they try to access their account after September 17, 2026. What this means for your organisation: - Users who’ve signed in on or after April 28, 2026 are unaffected. - Users who haven’t logged in since April 28, 2026 will need a password reset the next time they access their account after September 17, 2026. - As a Control Panel administrator, you can perform this reset for any affected user whenever it’s needed. We’re sharing this so you’re aware of the potential impact and can support any inactive users smoothly if and when they need access again. If you’d like to review which of your users may be affected, you can check sign-in activity in the Control Panel at any time. September 17, 2026 14:45 CEST Active - The maintenance has now started. September 18, 2026 13:06 CEST Active - Although the maintenance is complete, this status will remain visible for awareness until Monday, 21 September. September 23, 2026 08:48 CEST Completed - The monitoring of the maintenance has been completed.
