Studies show a dangerous gap in security awareness: the email inbox, as the central access to digital identity, is often inadequately protected, while forms of attack are becoming more complex.
Despite increasing investments in digital security, users underestimate the threat of their email account as a gateway to identity theft. New data shows an alarming gap in security awareness.
The email inbox is becoming the most dangerous weak point in digital defense. While consumers often strictly protect their online banking access, their email account often remains poorly secured – even though it serves as a master key for the entire digital identity. This is proven by current studies published on Tuesday.

Whether online banking, PayPal or access to your private email inbox – this sensitive data is often inadequately protected, especially on your smartphone. This free guide shows you in simple steps how to effectively protect your Android device against hacker attacks and data theft. Discover 5 protective measures that can be implemented immediately
Survey reveals paradoxical security behavior

A representative YouGov survey commissioned by the Safe Action Initiative (ISH) shows significant deficits. Only 13 percent of those surveyed protect their private email inbox with one Multi-factor authentication (MFA). For comparison: with online banking it is around 30 percent.
This misjudgment is fatal. Almost all online services use the email address for password resets. Whoever controls the mailbox has access to social media, cloud storage and company accounts. “The email inbox is the central access to digital identity,” warns Harald Schmidt from ISH.
Attacks become more precise and interactive
The “M-Trends 2026” report published at the same time by Google subsidiary Mandiant confirms the qualitative intensification of the threat. Classic phishing emails only make up around 6 percent of initial attacks. But their danger has increased.
Today, attackers often only use emails as bait. Their goal: to lure victims into interactive traps such as fake video conferences or voice phishing calls. These “live” attacks are harder for automated security systems to detect. In cloud environments, phishing is responsible for 15 percent of all compromises.

BSI is pushing for higher security standards
The Federal Office for Information Security (BSI) has already announced stricter rules for webmail services at the end of 2025. “Responsibility must no longer lie solely with the user,” says Caroline Krohn, digital expert at BSI. Providers would have to make security features such as MFA standard.
Current security vulnerabilities, such as those recently found in the widely used RoundCube software, are exacerbating the problem. They allow attackers to completely take over email systems. The BSI therefore urgently recommends the implementation of modern protocols such as DMARC, SPF and DKIM.
Double strategy: technology and human firewall
Experts recommend a two-pronged defense. Technically apply Passkeys as the most promising solution. These passwordless, cryptographic keys are more resistant to phishing.
At the same time, raising user awareness remains crucial. Companies rely on regular phishing simulations. The aim is to create a culture of skepticism – even towards supposed instructions from management. The “human firewall” becomes a critical factor.
Outlook: AI duel and farewell to the password
The race between attackers and defenders is heating up. Artificial intelligence plays a key role on both sides: for mass personalized phishing campaigns as well as for real-time anomaly detection.
Industry observers expect that pure password authentication will be largely replaced in companies by the end of 2026. Protecting your email inbox is changing from an IT task to a strategic element of risk management.
