Common Email Threats
- Ransomware
- Phishing
- Malware
- Spam
- Domain Compromise
- Account Takeover
- Internal Threats
- Spoofing
90% of breaches occur by email, and cloud email platforms like Microsoft 365 do not necessarily have security that complies. Built-in security is not enough, meaning it is best to add an extra layer of security.
