Microsoft 365 hardening
Secure your Microsoft 365 environment before attackers exploit it.
Microsoft 365 is powerful, but out of the box it isn't secure enough for today's threats. Many businesses assume Microsoft handles security. In reality, you are responsible for securing identities, email, data and access.
We go through your tenant setting by setting, close the gaps, and explain what we changed. Your staff keep working the way they do now. They just become a lot harder to impersonate.
What's included
Email security configuration
SPF, DKIM and DMARC to prevent spoofing, plus Defender for Office 365 against phishing, ransomware and malicious links.
Multi-factor authentication
MFA enforced through conditional access, applied by location, device and risk level.
Identity and access governance
Role-based access control, restricted guest access and removal of unnecessary admin rights.
Safe Attachments and Safe Links
Suspicious attachments are opened in a sandbox and links are rewritten to block credential harvesting.
Audit logging and alerting
Unified and mailbox audit logs turned on and tuned, so suspicious activity gets noticed.
Mobile and BYOD security
Intune or MDM to enforce encryption, block jailbroken devices and manage data on phones and tablets.
Teams and SharePoint permissions review
Sharing settings reviewed so documents aren't overexposed, with guest access policies enforced.
