Microsoft 365 hardening built around your business

Security hardening means reviewing and strengthening configurations to reduce unnecessary access and exposure. At BCS, the work starts with your users, devices, information, existing tools, and licenses. We agree on priorities, test changes, and document who is responsible for ongoing checks.

What BCS can help secure

Identity and administrator access

We review who can sign in, who has administrative privileges, and how access changes when people join or leave. Work can include MFA coverage, phishing-resistant authentication, Conditional Access where licensed, separate admin accounts, emergency-access planning, and application permissions.

Practical question: Can a former employee or contractor still reach company information?

Exchange Online and email security

We review mailbox permissions, forwarding rules, phishing protection, and domain authentication settings such as SPF, DKIM, and DMARC. Where supported by your licenses, we help configure Defender for Office 365 protection and user reporting procedures.

Intune and device protection

We help enroll eligible devices, establish configuration and compliance policies, manage applications, and review encryption, updates, endpoint protection, and local administrator access. We compare managed-device coverage with your inventory to identify gaps.

SharePoint and OneDrive sharing

We review site and file permissions, guest access, external sharing, and employee file ownership. We help your team distinguish personal work files from shared business records and plan access when an employee leaves.

Practical question: Which outside users can still open your files?

Purview and sensitive information

We help plan sensitivity labels, data loss prevention, retention, and auditing around your data and business requirements. The exact features and workloads must be checked against your subscriptions before implementation.

Monitoring, response, and recovery

We help define who reviews alerts, who can contain an incident, what evidence to retain, and how recovery is tested. Where appropriate, we coordinate Microsoft tools with your chosen endpoint protection, SIEM, and managed detection and response services.

Plan for cloud outages and business continuity.

Microsoft Secure Score review and improvement

Microsoft Secure Score organizes security recommendations and tracks progress across supported products. Identity Secure Score focuses on identity-related recommendations. We use these tools to help prioritize work, investigate gaps, and explain changes to business owners.

  • Establish a starting point: review recommendations alongside your actual configuration and business risks.
  • Choose useful improvements: consider user impact, licensing, existing protections, and dependencies.
  • Verify the result: test controls and retain implementation evidence.
  • Review over time: revisit outstanding work and changes in the environment.

A higher score is not a security guarantee or a compliance certification. Some recommendations may need different licenses or a documented alternative approach. We focus on working safeguards and clear responsibilities.

From assessment to ongoing checks

  1. Discover: review accounts, licenses, devices, sharing, security tools, and your team’s concerns.
  2. Prioritize: provide findings and a proposed work plan, with scope and pricing agreed before implementation.
  3. Implement carefully: pilot changes where practical, plan recovery access, and communicate user impacts.
  4. Validate: check expected sign-in, device, email, and sharing behavior; document exceptions.
  5. Maintain: agree on alert handling, access reviews, onboarding and offboarding, and follow-up checks.

Assessment depth, deliverables, monitoring coverage, and review frequency depend on the agreed engagement. An initial conversation helps determine what your business needs.

Watch: Microsoft 365 identity and mailbox investigations

A suspicious mailbox is one reason identity, email, and response procedures need to work together. Watch our administrator-response video, then read the accompanying hacked Microsoft 365 account response guide for Austin businesses.

Match security controls to the right Microsoft licenses

Business Basic, Business Standard, Business Premium, Microsoft 365 E3, and Microsoft 365 E5 provide different capabilities. Office 365 E3 and E5 also differ from the Microsoft 365 suites. Add-ons, assigned user licenses, and the workload involved can change what is available.

We review the features you need before recommending a subscription change. Buying a license still leaves configuration, testing, and ongoing administration to be done. See our Microsoft 365 licensing guide.

If you have SOC 2, CMMC, HIPAA, or other obligations, discuss scope and requirements with us. A Microsoft license or a high Secure Score alone does not establish compliance.

Microsoft 365 security questions

Does Microsoft 365 automatically secure everything?

Microsoft provides platform protections and security features. Your organization still needs appropriate configuration, access decisions, user procedures, and ongoing review. The work depends on your environment and licenses.

Can you harden our existing tenant?

Yes. BCS can assess an existing Microsoft 365 environment and agree on a prioritized improvement plan. We can coordinate with your current IT team and other providers.

Will stricter settings lock users out?

Security changes can affect sign-in, applications, devices, and sharing. We plan appropriate testing, emergency access, and user communication before rollout.

Can Microsoft Defender work with our other security tools?

Integration and coexistence depend on the products, licenses, connectors, and response workflow. We review the actual design and define who acts on alerts rather than assuming every tool will work together automatically.

What should we receive from a security review?

Agree on the deliverables before work begins. These may include findings, prioritized actions, licensing gaps, assigned responsibilities, and a follow-up plan. Implementation and ongoing monitoring should be scoped explicitly.
