Microsoft 365 Security Assessment & Hardening

Lock Down Your Microsoft 365 Tenant and Keep It Secure

Microsoft 365 includes powerful security tools across Entra ID, Exchange Online, Microsoft Defender, Intune, SharePoint, OneDrive, and Teams, but they only protect your business when they are configured correctly and maintained over time. Our Microsoft 365 Security Assessment & Hardening service starts with a comprehensive review of your tenant, fixes the gaps we find, and then monitors your configuration every month so it stays aligned with a documented security baseline.

Why Choose Our Microsoft 365 Security Assessment & Hardening Services?

Most Microsoft 365 tenants are set up once and then left alone while Microsoft keeps changing features, licensing, and recommended settings. Harbour Technology Consulting treats tenant security as an ongoing process rather than a one-time project, giving you measurable improvement and a partner who keeps watch after the initial work is done.

Documented Security Baseline

We define the desired security configuration for your tenant using HTC standards, your specific requirements, and recognized security frameworks where appropriate.

Configuration Drift Monitoring

Ongoing assessments catch policy changes and configuration drift that quietly weaken your tenant, before they turn into a security incident.

Why Microsoft 365 Security Configuration Matters

Your Microsoft 365 tenant holds your email, files, user identities, and collaboration tools, which makes it one of the most targeted systems in your business. A single misconfigured policy, legacy authentication setting, or overly permissive sharing rule can give an attacker the opening they need.

Reduced Attack Surface

Closing configuration gaps in identity, email, and sharing settings removes the easy entry points attackers look for first.

Audit and Exam Readiness

Documented baselines and executive reporting support cyber insurance reviews, compliance audits, and regulatory examinations.

Benefits of Microsoft 365 Security Assessment & Hardening

Partnering with Harbour Technology Consulting helps you get full value from the security capabilities you already pay for in Microsoft 365. Our structured approach delivers a hardened tenant, a documented baseline, continuous visibility into configuration changes, and reporting that shows real progress over time.

Benefit #1: Maximize Your Investment

Use the Security Features You Already Own

Many businesses pay for Microsoft 365 security capabilities they have never fully configured. We make sure features like Conditional Access, Defender policies, and Intune compliance rules are set up correctly and working for you, without adding tools you don't need.

Benefit #2: Proactive Protection

Fix Weaknesses Before They Are Exploited

Rather than waiting for an incident to expose a configuration weakness, we identify and correct gaps proactively, reducing the risk of account compromise, data leakage, and email-based attacks.

Benefit #3: Continuous Alignment

A Tenant That Stays Secure Over Time

Microsoft 365 changes constantly, and so do the people managing it. Monthly drift monitoring and remediation keep your tenant aligned with its baseline instead of slowly slipping back to an insecure state.

Benefit #4: Experienced Local Team

25+ Years of IT and Security Expertise

Our team has delivered IT, infrastructure, and cybersecurity services for more than 25 years. Businesses across Dayton, Cincinnati, Columbus, and Indianapolis rely on us for a structured, measurable approach to Microsoft 365 security.
