If you host your own Email server, then a Firewall Service that actively monitors and scans incoming email for Malware and Spam before it reaches your Email Server should be a primary part of your Cyber-Resilience Strategy, as once a malicious Email reaches your internal systems, it may already be too late.
Contact Us at Hanby IT Solutions for details of our hosted Gateway which will reduce this risk on your behalf. Or if you prefer we can install a Gateway on your premises as part of your existing setup.
