Protect your Microsoft O365 tenant

Share This Post

An organisation’s Microsoft 365 tenant is susceptible to many external and insider threats when not properly configured. At every level of licensing there are at least some level of security controls that could be implemented to reduce the risk of attack.

These necessary security controls can be broken down into 6 categories:

  • Account Protection & Authentication: including controls only allowing legitimate sign-in activity (for example MFA, geo-block, SSO, self-service password reset) as well as anomaly detection to determine risky sign-ins and at-risk users.
  • Application Permissions: which prevents users from integrating third-party applications, installing add-ins, and creating other connections to your Microsoft tenant that should not be allowed.
  • Data Management & Storage: which enforces Data Loss Prevention, data classification, and limits external sharing on sensitive company data where appropriate.
  • Email Security: to prevent phishing, spam, and malware from being delivered to end users, as well as blocking malicious links from being opened.
  • Alerting & Auditing: which provides notifications and reports to administrators of malicious & suspicious events observed across the tenant that could lead to security incidents.
  • Mobile Device Management: to ensure that company data access on mobile devices and laptops are always secured and monitored when outside of the organisation.

If you are unsure that your organisation covers these controls, or you want to implement these controls, get in contact with Brace168!

AI has moved from experiment to operating model, but its real value—and risk—comes down to your data. With 75% of knowledge workers already using AI tools, often without IT oversight, shadow AI is driving a costly wave of breaches that organisations can’t afford to ignore. This whitepaper cuts through the anxiety to show how Microsoft Purview gives you the discovery, classification, and policy controls to make AI safe and productive, turning data security from a blocker into an AI enabler.
