Boost your business's credibility with our innovative email security solution.
Phishing emails, fake emails, and information leaks via email...
Email remains the most widely used, yet also the most exploited attack vector.
In recent years, email phishing, spear phishing, account hijacking, and information leaks have been on the rise. Existing spam blocking systems and general security systems are unable to block sophisticated social engineering-based phishing emails .
In particular, attacks that impersonate internal company employees or use email addresses identical to those of actual business partners are difficult to detect with existing security technologies , and when an incident occurs, it leads to financial loss and a decline in trust .
Why You Need a Next-Generation Email Security Solution
Existing email security solutions cannot completely protect against social engineering phishing emails.
Email-based attacks are evolving further by leveraging automation and AI technologies .
An integrated response system is needed , from pre-blocking to impersonation verification to user warning .
Mail security requires more than simple filtering; it requires trust-based verification and behavior-based detection.
