Not every risky email should be blocked outright. Some messages may be legitimate but still deserve extra scrutiny. Until now, email security has largely followed a simple model: a message is either delivered or blocked. While this works well for clearly malicious emails, many modern attacks operate in a gray area where the risk is real, but not high enough to justify rejecting the message.
Cybercriminals have been relying on the same trick for years: hide malicious content where traditional email security tools cannot easily inspect it. Password-protected attachments, QR-coded URLs, and redirector-wrapped links have often acted as convenient hiding places for attackers. But it's possible to stop these threats.
Email hijacking remains one of the most effective techniques used by cybercriminals to conduct fraud, steal sensitive information, and impersonate trusted individuals.With new AI functionalities (dubbed "Anubis.AI") in our Mail Protection Service, we can stop such threats!
Many companies today still don't see the need for email security. They think this way even though it's a vital part of cybersecurity. What’s more, they fail to grasp the reality of under-prioritizing email security.
Email remains the primary communication channel for most organizations, but it was never designed with modern security requirements in mind. While protocols such as SPF, DKIM, and DMARC help verify sender identity, they do not protect emails while they are traveling between mail servers. This is where MTA-STS (Mail Transfer Agent Strict Transport Security) plays a crucial role.
As Cisco grew into the dominant email security vendor, A saying became loud into this space: "Nobody ever got fired for buying Cisco." The idea was that choosing the market leader was the safest decision because it was easy to justify if things went wrong. In today's email cybersecurity, however, that mindset can be dangerous.
Email remains the primary entry point for phishing, fraud, malware, and Business Email Compromise (BEC) attacks. While Microsoft 365 provides a strong foundation, organizations need additional layers of protection to defend against increasingly sophisticated threats
The email landscape has fundamentally changed — and in 2026, there is no ambiguity left:
DMARC is no longer optional. It is enforced.
Over the past two years, the world’s largest mailbox providers — Google, Yahoo, and Microsoft — have implemented strict authentication requirements. Today, any domain sending bulk email must have properly configured SPF, DKIM, and DMARC, or risk outright rejection. [mailcop.net], [redsift.com]
This shift marks the end of the “open email era” and the beginning of a trust-based ecosystem where authentication is mandatory.
The email security landscape is increasingly shaped by robust protocols for authentication, data protection, and secure communication. Among these, MTA-STS is emerging as a critical standard, strengthening the enforcement of encrypted channels for email delivery.
Phishing attacks, which trick users into revealing sensitive information or installing malware, have grown more sophisticated and localized. Putting it simple: the frauds you'll get in Portugal are completely different from US, Singapore or any other place.
