Why do I need Email Security?

Email is the default business communication standard. Yet despite its maturity it is fraught with security weaknesses and plagued with threats such as spam, phishing and malware. Spam and phishing have undoubtedly been the biggest negatives for email. Spam volume has more than doubled since 2008 and continues to worsen. Spam has long been the attack vector of choice for hackers and criminals and now they have expanded the assault on your email via botnets, fake anti-virus programs and blended threats.

Incoming email threats are not the only concern. Your organization may be exposed to intentional and unintentional security risk from within. Most organizations place special significance on their commercially sensitive and private data which is susceptible to leakage via email. As email is widely considered to be electronic letterhead, the conduct of your employees when using email reflects directly on your business. You need to be certain that email use is safe, secure, productive and appropriate.
