Why do organizations need email security?

Updated: Mar 2, 2020

This question generally leads one to think “Is email security really important?”

Answer to the question is: “Yes! It is important”, Emails have been the easiest and quickest mode of communication be it for personal or for business reasons by far.

As a result, hackers find emails as an easy medium to spread malwares through deceptive spam emails, convincing target users to click and open the attachments on the links that come along. By opening the link or attachments the users are redirected to malicious websites or end up opening a malicious document and by this way, the attackers install the malware from back-end on to the user’s system and gaining access to the individual's private details such as financial and banking information or private conversations or even can gain access to company’s network to steal company’s data; causing security breach, and yes, security breaches continue to happen each year despite the security solutions designed to block threats. It is no wonder to believe that most of the threats are delivered via email which we all know is the easiest way.

According to Statista, in the year 2019 itself, 294 billion emails were sent and received, and the number is constantly rising

Here are 3 main reasons which will help you to understand why we need email security

Reason 1: Most common IT security threat for organizations

Without a doubt email is the most common way for an attacker to access your private emails and for business, to bring the entire network down, also impacting the reputation of your organization.

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

Reason 2: Evolving email threats lead to a rise in organization's risk of compromise

With email as the main entry point for attackers, it’s important that companies ensure their email protection solution is actually protecting them from new and evolving threats. New email security defenses are helping organizations significantly in improving their email security.

Reason 3: Just having one type of security is not enough

Hackers are developing sophisticated ways to bypass email security systems at a rapid pace, which includes redirecting genuine URL addresses to phishing URLs. The growing challenge is for organizations to ensure that they have the right defenses in place to detect and stop such threats arising from a simple mail. Often, additional layers of email security are needed on top-off baseline email security.

Important Strategies you should implement

  • Be careful with passwords and credentials.

Passwords, alone, are not secure online – at least not in modern times. Make sure to change your passwords periodically. Having a weak password will increase the chances of online attacks done by utilizing stolen passwords, weak passwords, brute-force guessing, phishing, man-in-the-middle, and other such attacks.

  • Scanning and Configurations

Effective email security solutions are a necessity in today’s world for protecting mailboxes against spam mails and malwares. However, it is also crucial to ensure that any solution configured is tested to meet the organization’s security requirements – while also not impacting the usability of a primary communication system. Proper Domain Name System (DNS) configurations for Sender Policy Framework (SPF), DomainKeys Identified Mail (DKIM), and Domain-based Message Authentication, Reporting, and Conformance (DMARC) are required to help protect your organization’s email reputation, while also helping to defend against phishing attacks.

  • Importance of Visibility

Most organizations have no idea on what is happening in their network where emails are coming and going. What do they need to improve? Having this visibility will help your organization protect against email based threats. If you know where emails are coming from and what they contain, you will be able to prevent threats across your environment, and hence can reduce the risk of any potential fraudulent emails.


As new organizations are born each day, email security is important and plays a vital role in every organization and there should be necessary actions taken to make sure there is no security breach. It becomes the responsibility of every business to protect themselves, their clients' and employees' sensitive personal information. Neglecting the same can cause a chaos in an organization resulting tremendous loss of money, reputation and incurring a heavy legal charges.
