Best Email Security Services of 2025: Features, Comparison & How to Choose
According to statistics, scammers send an estimated 3.4 billion phishing emails per day that pretend to be from reliable sources.
Nowadays, email is the primary means of communication for most businesses.
But did you know that email isn’t as secure as we believe it to be?
Cybercriminals efficiently use email communication security gaps to deceive recipients and expose personal information. Phishing is the most popular attack technique, in which criminals pose as trustworthy organisations in an attempt to fool consumers into revealing personal information.
Only clicking on a link is enough for a hacker to gain access to your system.
“Help Save Children from Ukraine” is one of the email subject lines that fraudsters have been using as a phishing attack to take advantage of fundraising scams ever since the Russia-Ukraine war made news.
Email security has become a vital requirement for both consumers and corporations due to the increase in email-based risks.
