Office 365 Enterprise Plans Security and Compliance Features Overview

Office 365 Enterprise Security

As more and more businesses are moving to the cloud, it’s paramount that security is top of mind. Protecting your users as well as your most important, sensitive and confidential data is critical to business success. If you’re considering moving to the cloud with Microsoft Office 365, here is a list of security and compliance features found in each of the Enterprise licenses (E1, E3, and E5):

Office 365 E1 Plan Security Features:

Access to the Security and Compliance Center

The Office 365 Security and Compliance Center will be your main portal for protecting your data in O365. As a global administrator, you’ll be able to manage your security and compliance settings for all of your data across O365.

Threat Management

Threat management includes capabilities like mail filtering and anti-malware. Threat managements is designed to control and manage mobile device access to your data, protect your data from data loss (intentional or not), and protect inbound and outbound messages from malicious software and spam. By leveraging Threat Management, you can determine whether senders are maliciously spoofing accounts from your domain. Microsoft continues to add new features to Threat Management, but here are some currently available additional features within the Threat Management tool:

Mail filtering
  • Fine-tune and monitor settings that help prevent spam in Office 365. Create, allow, and block lists; determine who is spoofing your domain and why; and configure and view spam filter policies.
  • Set up policies to verify your users aren’t sending spam. This can happen if a user’s computer gets infected by malware that is programmed to send email messages.
Anti-malware
  • Protect against viruses and spyware traveling to or from your organization in Office 365.
DKIM
  • DomainKeys Identified Mail (DKIM) helps ensure that other email systems trust messages you send from Office 365. DKIM does this by adding a unique digital signature to email messages sent from your organization. Email systems that receive email from you can use this digital signature to help determine if the email is legitimate.
  • If you do not set up DKIM yourself, Office 365 uses its default policy and keys that it creates in order to enable DKIM for your domain. Also, if you disable DKIM signing, after a period of time, Office 365 automatically enables the Office 365 default policy for your domain.
  • DKIM is only one email authentication technique used by Office 365. To be most effective, DKIM is used along with other supported techniques such as Sender Policy Framework (SPF) and Domain-based Message Authentication, Reporting, and Conformance (DMARC). Together, these domain-based authentication technologies help prevent spam and unwanted spoofing.
