When’s the last time you evaluated your email security? Most organizations’ IT professionals trust the security  already in place when email systems are internally hosted, or trust the security provided by their email provider (such as Office 365 email security). However, security breaches continue to happen each year, despite the security solutions designed to block threats. And, most of these threats are delivered via email.


In 2017, 269 billion emails were sent and received, according to Statista, with businesses accounting for half of that. That number is only projected to grow.


If your email security solution isn’t adequately protecting your organization, you may be part of the growing number of companies who have had costly security breaches. Gartner estimates that there were between 2 million and 3 million successful ransomware attacks in 2016, and that the frequency will double year over year through 2019.


That’s why it may be in your best interest to convince your boss to upgrade your email security. Here are five reasons that can help your boss understand why your email security solution may need to be upgraded:

Reason 1: Email is the most common IT security threat for organizations

Whether it be malware, phishing, URL-based threats, impostor-driven schemes like business email compromise (BEC), email is the primary method hackers use to deliver harmful programs to an organization or individual.

An estimated 75 percent of identified, impactful threats were initially entered via email attachments and 46 percent of attacks were executed by users clicking web links in email, according to the SANS Cyber Security survey.

Reason 2: Email-based attacks affect the entire organization

Due to the continued prevalence of email, a harmful email that slips through your defense can wreak havoc throughout your organization. All employees are affected by phishing email, using carriers, banks or sharing solutions brands name to lure them. It can seriously harm your company, especially if a ransomware effectively holds your company information and/or systems hostage.

An average business user receives 4,380 potentially malicious emails every year, according to the Verizon 2017 Data Breach Investigation Report.

Reason 3: Basic anti-spam email filters are not enough

Hackers are developing increasingly sophisticated ways to bypass email security systems, including redirecting good URL addresses to phishing URLs. The growing challenge then is for organizations to ensure they have the right email defenses in place to detect and stop advanced threats. Often, additional layers of email security are needed on top of base email security.

As Gartner notes in the Key Findings Gartner market guide, May 2017, “advanced threats are easily bypassing the signature-based and reputation-based prevention mechanisms for email security. (We recommend organizations) supplement gaps in the advanced threat defense capabilities of an incumbent SEG by adding a specialized product tailored for this purpose…”

Reason 4: Email-based threats are evolving and increasing, putting more organizations at risk every year.
