Mimecast helps broadcaster Network 10 eliminate email-borne malware and false positives


Media organizations are particularly vulnerable to outside attacks due to their high profile. Network 10 has a mature IT practice for resolving ransomware attacks, but reactive response and remediation are time and resource-intensive activities.

“In the last two to three years, we have seen a significant increase in malicious email attacks including URL-type attacks,” says Jason Tuendemann, Chief Information and Technology Officer with Network 10.

Tuendemann knew a better approach would be to stop malware from entering the network in the first place. He sought a new email management solution that would defend against the growing volumes of malicious emails, improve security and empower users to work more safely online in their Office 365 environment.


Network 10 evaluated several email security solutions, and after a proof-of-concept selected Mimecast Email Security, which was appealing for its cloud design, robust email filtering, archiving capabilities and tight integration with Office 365. Importantly, the proof-of-concept showed very few false positives.

“We receive a lot of information from the outside, so we have to be very careful about how much we block,” Tuendemann explains. “Delivery of information to the business needs to be very timely particularly with news operations. So it’s a balancing act to decide how much filtering you put in place; there’s nothing more frustrating for people than having legitimate email blocked.”

Network 10 coupled its Mimecast implementation with training for employees to help them identify and avoid phishing scams and malicious URLs.


“Since implementing Mimecast we haven’t suffered a single URL type incident,” Tuendemann says. 80% of incoming email is blocked as spam or malicious, including 50 malware samples and 250 potential whaling attacks avoided per month. IT staff now have time to focus on other tasks, and through education Network 10 employees have a heightened awareness of the importance of security.
