Despite decades of technological advancement, email remains the predominant attack vector for cybercriminals, with estimates suggesting that 80-90 percent of cyberattacks originate through email channels. While the cybersecurity industry has made significant strides in other areas, many businesses continue to rely on outdated email security measures that leave them vulnerable to increasingly sophisticated threats. This protection gap demands immediate attention from IT leaders.

Traditional secure email gateways (SEGs) like Mimecast and Proofpoint have served as the backbone of organizational email security for years. Similar to how traditional firewalls operate at network perimeters, these gateways excel at blocking known threats through signature-based detection and basic filtering rules. However, just as modern network security has evolved beyond simple perimeter defenses, email security requires a more sophisticated approach.

Hardly a week goes by without news of another email-based attack via phishing or Business Email Compromise (BEC) scam. These types of attacks can cause a great deal of damage to infrastructure and an organization’s image, whether it is a large enterprise, a small-medium business (SMB) or even much smaller retailers. The FBI (Federal Bureau of Investigation) reports that the average financial loss per BEC attack is $125,000 and last year estimated the Business Email fraud industry to be valued at a whopping $50 billion.

If someone responds on behalf of the executive, they could unknowingly give away the keys to the kingdom, causing significant losses. With that in mind, let’s review some of the larger email security trends.

The software offers a comprehensive set of productivity tools; flexible, scalable, and affordable licensing options, and compliance and security capabilities. However, given the ever-growing and persistent threat of cyberattacks, for email security, the standard security safeguards offered are insufficient.

Analysis of over 1 billion emails worldwide shows that emails are the preferred vehicle of cybercriminals. Email-delivered malware remains a favorite, increasing by 276 percent between January and December of last year. Additionally, attachments are growing as a threat. In Q4 of 2023, EML attachments increased 10-fold. Criminals are sending malicious payloads via EML files because they get overlooked when attached to the actual phishing email, which comes out clean.

Today, Proton Mail has expanded its secure communication platform with the launch of a dedicated desktop app, which was previously released in beta. The new desktop app complements Proton Mail’s existing web and mobile applications, ensuring users can maintain their email privacy across all devices without being confined to a web browser.

Proton Mail aims to provide users with the ability to access their email in their preferred manner without compromising privacy. The new desktop app addresses the privacy concerns associated with using email services like Outlook, which shares data with numerous external partners, and the risks of accessing emails through browsers like Chrome, which can expose browsing history to advertisers or be exploited by malicious browser extensions.
