Microsoft 365 Email Security
Microsoft 365 Email Security – Strengthen the Security of Microsoft 365 – Add Anti-Phishing, Spear-Phishing Detection, Email Continuity, and CEO Fraud Filtering!
Spambrella provides advanced defenses against the most sophisticated phishing attacks. Businesses of all sizes are adopting cloud-based Microsoft Office 365 as a way to give users greater flexibility and access to core business applications anytime, anywhere, and on virtually any device.
While Office 365 email security includes built-in email filtering security capabilities, additional protection is needed when it comes to spear-phishing exploits that use social engineering methods and other tactics to find and ex-filtrate vital sensitive business data.

Spambrella Email Protection solutions provide enterprise-grade security for Microsoft Office 365, defending against phishing attacks faster, offering greater reliability, and improving email continuity.
Enterprise-grade email protection is available for most popular email form factors, along with the flexibility and scalability to support changing customer environments in any sector.
Why You Need Additional Security for Office 365
Office 365 is an indispensable business tool and a key attack vector for email phishing. With 95% of all attacks originating from spear-phishing attempts, more robust email security is a top priority. It’s easy to see why spear phishing has become a popular mode of attack.
According to the 2023 Verizon Data Breach Investigations Report, one in five people will click on a URL in a phishing message and human resources and finance, departments where most sensitive data resides, are the biggest offenders.
In a recent phishing quiz conducted by Intel Security, 80% of 60,000 users across 49 countries failed to identify at least one phishing email.
