Enhanced email security tools provide greater protection against email-borne threats and malware, and minimise the likelihood of related information security incidents. The first tool is an email gateway to filter all inbound messages sent externally with the ability to stop messages prior to delivery to your inbox. The second tool is a cloud security tool that integrates with Nexus365 and allows for finer grained delivery filtering as email arrives. This tool filters messages sent from internal addresses, as well offering extra checking of externally received messages. The cloud security tool continuously scans all mailboxes for malicious content – including post delivery – and removes messages according to the University's email policy.
