How is Spambrella different from the built-in Office 365 security features?

Despite its recent improvements, Microsoft Defender for Office 365 isn’t flawless in terms of email security. Its features are not effective enough to repel zero-day attacks and advanced spear phishing attempts, not to mention its encryption gaps and DLP limitations. Spambrella is different from Microsoft Defender because it has been developed to incorporate advanced ML algorithms for multi-level threat detection. Spambrella’s effectiveness rates for defending against sophisticated email attacks are much higher than those of built-in M365 tools.
