Email is arguably the longest serving yet most abused tool we have in business. We use email for personal and business for endless reasons so logically we must defend this channel. Email filtering is a critical weapon in a defence in depth strategy. More than just Spam, embedded media, hyperlinks, and phishing are the tip of the iceberg when it comes to the torrent of malicious content we receive daily. With on premise, cloud based, and hosted options, defence is scalable and affordable. Consider also leveraging sandboxing and web filtering. Endpoint protection should be the last line in email defence.
