Microsoft 365 Security Hardening for Ohio Businesses

Microsoft 365 is the most widely deployed business platform in the world — and one of the most frequently attacked. The default M365 configuration is not a security configuration. Without proper hardening, your Microsoft 365 environment is vulnerable to account takeover, data exfiltration, and BEC attacks even with a valid license.

Quick Answer

Microsoft 365 security hardening configures the security controls built into your M365 subscription that are off by default — including MFA enforcement, Conditional Access policies, Microsoft Defender for Office 365, Azure AD Identity Protection, data loss prevention, and audit logging. Securafy manages M365 security as part of all service tiers.

What M365 Security Hardening Covers

Multi-Factor Authentication (MFA): Enforced for all accounts via Conditional Access — not just "enabled" but truly enforced with no bypass. Securafy configures MFA to work with your FIDO2 keys, authenticator apps, or phone verification based on your security requirements.

Conditional Access policies: Controls that define which users can access which applications from which locations and devices. Block legacy authentication protocols, require compliant devices, enforce risk-based sign-in policies, and restrict access from high-risk countries.

Microsoft Defender for Office 365: ATP Safe Links and Safe Attachments for email, SharePoint, Teams, and OneDrive. Anti-phishing policies with impersonation protection. Real-time threat detection integrated with Securafy's SOC.

Azure AD Identity Protection: Detects risky sign-ins (impossible travel, anonymous IP, malware-linked IPs, leaked credentials) and triggers automatic remediation or alerts Securafy's SOC.

Microsoft Secure Score: Securafy tracks your Microsoft Secure Score and benchmarks it against similar organizations. Improvement roadmap maintained and implemented continuously.

The Security Settings Microsoft Leaves Off by Default

Most businesses are surprised to learn how many security controls in their M365 subscription are off by default. Microsoft ships M365 optimized for usability, not security. Without active hardening, your environment likely has: legacy authentication protocols enabled (SMTP, IMAP — used by attackers to bypass MFA), no Conditional Access policies, audit logging not enabled or retained, external sharing unrestricted in SharePoint/Teams, and no identity risk policies active.

Securafy's M365 security baseline addresses all of these in a single configuration project, then maintains them continuously as Microsoft releases new security features and controls.

About Microsoft 365 Security & Backup

“Microsoft is explicit about this in their shared-responsibility model: backup is your job. We see customers learn this the hard way when ransomware encrypts their OneDrive and the recycle bin is empty 30 days later.”

Rodney Hall President & COO, Securafy

Why can't businesses rely on Microsoft 365 for data backup?

Businesses can't rely on Microsoft 365 alone for backup because Microsoft's data protection model is built around availability, not long-term recovery. The shared responsibility model puts data backup, retention beyond the recycle bin window (30 days for most items), and protection against accidental deletion or ransomware encryption on the customer — not Microsoft.

Which companies provide Microsoft 365 SaaS backup for accounting and auditing firms?

Microsoft 365 SaaS backup for accounting and auditing firms requires daily incremental backups, point-in-time recovery, retention long enough to satisfy audit requirements (typically 7 years for tax and financial records), and immutable storage. Securafy provides M365 SaaS backup for accounting firms with this retention and audit-grade documentation.

Common Questions About Microsoft 365 Security

It depends on your license tier. Microsoft 365 Business Basic includes minimal security features. Business Premium includes Defender for Office 365 Plan 1, Intune, and Azure AD P1 — but none of it is pre-configured. Securafy deploys, configures, and manages these features as part of your service tier.
Microsoft Secure Score is a measurement of your organization's security posture based on your M365 configuration. The average score for SMBs is 30-40 out of 100. Securafy targets a score above 70 for all clients and maintains it through continuous configuration management.
Properly implemented MFA and Conditional Access policies are transparent to users during normal operations. Securafy tests all changes in staging configurations before applying to production and maintains rollback capability for all configuration changes.
Yes, significantly. MFA, audit logging, data loss prevention, and email security are all commonly required by cyber insurance carriers. Documented M365 hardening to a recognized baseline (CIS Benchmark or Microsoft's own security baseline) strengthens your insurance application and may reduce your premium.
