4. Implement additional security software
Businesses serious about safeguarding will want to choose a robust, email-specific tool like SolarWinds Mail Assure. This cloud-based solution focuses solely on email security, at an affordable per mailbox rate for any businesses of any size. With no additional hardware or maintenance needed, this tool integrates with Office 365 to protect against spam, viruses, malware, and phishing, using a global threats database to identify even the latest scams.
5. Use Office Message Encryption
Office 365 has Office Message Encryption on as a default. The service encrypts both incoming and outgoing email messages and is fully compatible with the web-based version of Outlook, Gmail, Yahoo!, and other common email platforms. Email message encryption is critical for protection against email-borne malware because it represents the first layer of security, blocking outsiders from viewing message content.
With little exception, the rule at your office should be to use either or both of the two protection options that Office Message Encryption provides when sending an email message: Do Not Forward and Encrypt.
Going beyond security basics
Each of these steps is uniquely important, but the secret to eliminating the threat of malware can’t be boiled down to a one-size-fits-all security posture. Developing a strong policy for safeguarding data and emails on Office 365 will require MSPs to understand each client’s unique security vulnerabilities and acknowledge the impact that certain best practices might have on their productivity. Following best security practices is only the first step toward establishing O365 security.
For optimal email security, it’s best to go beyond basic Office 365 functions and consider software that can keep an email server safe in the event of an attack or outage. Security isn’t a single, straightforward process, but a long journey that requires constant vigilance against advancing threats. These first steps will help lay a crucial foundation for companies hoping to remain protected from malware attacks.
