Safelisting, or a safelist (allowlist), is a cybersecurity strategy that approves a list of email addresses, IP addresses, domain names, or applications while denying all others. This is mainly for your IT administrators to use as a list of sites to allow just in case they get caught by IT protection.
Please safelist the following addresses:
portal@progresslearning.com
support@horizoneducation.com
info@horizoneducation.com.com
*.horizoneducation.com
horizoneducation.com
*.learnosity.com
The Email Server Domain: em9734.horizoneducation.com
