Solutions tested ranged from hosted email services with included security filtering to on-premises email security gateways.

The study was conducted during September and October 2017, and revealed that, on average, 10.5% of email delivered to users after being scanned by their current email security solution was spam, phishing, or malware email. The report also summarizes results for three separate cases, which illustrate how penetration rates can vary across different companies.
