6 Business Email Security Solutions to Protect from Spam and Phishing Attacks

Emails are an inherent part of your company’s business process, whether you want to interact with your customers, prospects, or employees.

Your email is a professional way to present your brand’s products and services, notify your customers about offers and deals. It might also contain sensitive information like bank account details, credit card numbers, trade talks, and many more.

Phishing campaigns are increasing both in terms of sophistication and volume. Such attacks are one of the major causes of security incidents and data breaches. A report by Verizon says that almost 1/3rd of all the data breaches in 2019 involved phishing.

These cyber-attacks aim at using disguised emails as their weapon to trick recipients into considering the message is useful to them. For instance, the message may read their bank’s request related to their bank credentials, a click to download an attachment by their company, imposed urgency, and more.

What’s the impact of phishing scams on a business?

Businesses around the globe suffer a huge loss in terms of money, reputation, regulatory fines, and much more. Even the biggies like Facebook and Google with impeccable security patches have been infiltrated by the cybercriminals and have lost millions of dollars, check this report.
