Spam, marketing, malicious or virus-enabled emails are not delivered to us probably 90 to 91 percent of the time because they are stopped external to the organization. That's a massive win for us. We don't have to worry about having to deal with all those emails going through our email servers.

The biggest issues are the social engineering and phishing. A lot of the spammers are actually quite good at spear phishing attacks and social engineering our emails. We obviously do checks. We run some simulations for our staff, where we try and train them so they are aware of what not to click on. Also, we have installed Umbrella and had it for a long time as well. Therefore, if something was malicious, and one of our users had clicked on it, Umbrella would usually stop anything outgoing. The combination of the two solutions has really helped secure our organization.
