Microsoft 365 Security Controls We Configure & Manage For You

Domain & Email Security

Protecting Your Brand & Communications. 

Maintain trust with domain and email security your clients can rely on.

What we configure at the domain level:
  • SPF Records: Verify emails are sent from authorized servers, preventing email spoofing.
  • DKIM: Ensures emails aren’t tampered with during delivery.
  • DMARC: Controls what happens to suspicious emails, protecting your domain from impersonation.

What we configure in Microsoft Defender:

  • Safe Links with real-time scanning.
  • Safe Attachments.
  • Advanced anti-phishing.
  • Advanced message encryption.
  • Advanced data loss prevention.
  • Advanced auditing.

Why this matters for your domain: Your domain name is the foundation of your entire online presence. It controls your website, your email, and much of your brand identity. If an attacker gains control of your domain, they can redirect your website traffic, intercept business email, impersonate your company, or hold your domain for ransom.

Domain security is one of the highest-priority, lowest-cost actions you can take to protect your business against domain hijacking, accidental loss, and unauthorized transfers.

Why this matters for email: 46.8% of all emails sent are spam. Billions of spam and phishing emails are sent each day, and AI is compounded this issue rapidly.

Microsoft Defender for Office 365 blocks threats, and keep updating their security graph in real time, to protect your accounts.

Identity & Access Management (Entra ID)

The Foundation Of Modern Security: Centralized user and device management. 

Your user identities control access to every business application, file, and email. This is where security starts.

What we configure:

  • Multi-factor authentication (MFA) beyond basic SMS codes.
  • Privileged access management for administrative accounts.
  • Single sign-on (SSO) across business applications.
  • Automated provisioning/deprovisioning when employees join or leave.
  • Password policies that satisfy compliance requirements.
  • Risk-based sign-in policies detecting compromised accounts.

Why this matters: Without Entra ID, you’re managing individual computers, not an organization. Users have different passwords for every app. You can’t enforce MFA across the company. When an employee leaves, you’re manually logging into 15 different systems to disable access. You have no central visibility into who can access what. 

Entra ID is the control plane for everything else, from Conditional Access to DLP and compliance reporting. It’s your foundation.

Device & Endpoint Security (Intune)

Your Trusted Devices: Manage and secure all devices accessing your data. Before you control what data flows where, you need to know and manage which devices are accessing it.

What we configure:

  • Device enrollment (Windows, Mac, iOS, Android).
  • Enforce encryption (BitLocker, FileVault) on all devices.
  • Require antivirus and firewall configuration.
  • OS update policies keeping devices current.
  • Application management (deploy business apps, block risky apps).
  • Remote wipe if device lost or stolen.
  • Security baseline enforcement for all managed devices.

Why this matters: Peace of mind and modern data security frameworks require “Do you enforce encryption? Can you remotely wipe lost devices?” Intune provides automated enforcement. This means that even if a device is stolen, a remote wipe removes business data within minutes. No breach notification required because data was encrypted.

Conditional Access Policies

Control who can access your data, from where, and on which devices.

Now that you have identity (Entra ID) and device management (Intune) foundations, Conditional Access enforces Zero Trust security by combining both.

What we implement:

  • Device compliance requirements – require managed, encrypted devices for business data.
  • Location-based controls – require VPN or office network for sensitive data.
  • Application-specific policies – financial data requires company device + MFA, email accessible with MFA only.
  • Risk-based access – block sign-ins from unfamiliar locations without additional verification.
  • Block non-compliant devices – if device isn’t encrypted or updated, access blocked.

Why this matters: Even if employee password is compromised, attackers can’t access data from unauthorized devices or locations. Multi-layered authentication and device compliance requirements dramatically reduce breach risk. If one security control fails, others prevent data loss.

Data Loss Prevention (DLP)

Stop sensitive data from leaving your organization inappropriately.

With identity secured, devices managed, and access controlled, DLP prevents your protected data from going where it shouldn’t.

What we can configure:

Cloud DLP (no Intune required):

  • Block emails containing credit card numbers to external recipients.
  • Prevent file uploads to personal OneDrive/cloud storage.
  • Restrict external sharing in SharePoint and Teams.
  • Require encryption for emails with sensitive data.

Endpoint DLP (requires Intune):

  • Control copy/paste of sensitive data between applications.
  • Block saving confidential files to USB drives.
  • Prevent printing of highly sensitive documents.
  • Monitor screen captures and clipboard operations.

What Can Be Detected:

Credit card numbers, SINs, banking information, client contracts, financial statements, legal documents, intellectual property, source code, product designs, Health information (PHI), personal data (PII).

Why this matters: Protecting your organizational and client data shields from harm, and  helps you meet Vendor Security Requirements.

Sensitive Data Protection

Classify, label, and protect your most important information.

DLP prevents data from going wrong places. Sensitivity labels ensure data carries protection with it wherever it goes.

What we can implement:

  • Sensitivity labels (Public, Internal, Confidential, Highly Confidential).
  • Automatic protection based on content (documents with “confidential” automatically labeled).
  • Encryption and rights management for confidential documents.
  • Visual markings (headers, footers, watermarks).
  • Control who can view, edit, print, forward documents.

How it works:

  • Employee creates proposal with client financial data.
  • Label automatically applied: “Confidential – External”.
  • Document encrypted automatically.
  • Forwarding disabled, expiration set.
  • Client can view but can’t forward to competitors.

Why this matters: Security questionnaires ask “How do you classify sensitive data? Do you encrypt confidential information?” Sensitivity labels provide documented classification.

External collaboration is made secure when you can share protected documents with clients and partners. Recipients access files without needing Microsoft 365. Control remains with your organization. Audit trails exist of external access. These are IT Risk Management and Compliance gold standards.

FAQ

What compliance standards can Microsoft 365 help small businesses meet?

Microsoft 365 provides technical controls supporting NIST Cybersecurity Framework (most flexible for Canadian SMBs), PCI DSS (mandatory if processing credit cards), PIPEDA (Canadian privacy law), and ISO 27001 (international standard) without requiring formal certification for most vendor requirements. NIST framework is not certification-based but provides documented security controls that satisfy most enterprise vendor questionnaires at lower cost than formal ISO 27001 certification ($30,000-50,000). Implementing NIST or ISO 27001 controls in Microsoft 365 gives documented security through configuration reports, Secure Score tracking, and policy documentation that vendors and auditors accept. Formal certification is only necessary when clients explicitly require certified ISO 27001 or SOC 2 Type 2 reports.
No, basic DLP for email, SharePoint, OneDrive, and Teams works without Intune device enrollment and covers most small business needs for preventing sensitive data exposure. Endpoint DLP (controlling copy/paste, USB drives, printing, and screen captures on Windows/Mac devices) requires Intune device management. Most vendor security screenings are satisfied with cloud-based DLP policies that detect credit card numbers, SINs, and confidential data in emails and files. Intune endpoint DLP provides additional protection for businesses handling highly sensitive information or meeting strict compliance requirements like PCI DSS Level 1.

Business Premium (up to 300 users) includes Entra ID with Conditional Access, Intune device management, Defender for Office 365 Plan 1, DLP for email and core apps, and basic sensitivity labels – sufficient for most Toronto small businesses needing vendor screening compliance. E3 (enterprise, unlimited users) adds advanced Conditional Access features, full DLP across all workloads, and eDiscovery for legal requirements. E5 adds advanced threat protection and insider risk management but is unnecessary for most SMBs unless clients specifically require Defender Plan 2. Business Premium satisfies NIST and basic ISO 27001 control requirements without the E3/E5 cost.

Yes, we help Toronto businesses pass SOC 2, ISO 27001, and custom vendor security questionnaires with typical timeline of 4-8 weeks from assessment to vendor-ready documentation. Our process maps Microsoft 365 capabilities (Entra ID MFA, Conditional Access, DLP, Intune device management) to specific vendor requirements like “Do you restrict administrative access?” or “Do you encrypt sensitive data?” We provide configuration implementation and documentation that satisfies vendor security reviews. Most vendor questionnaires ask similar questions about identity management, device security, data protection, and access controls that Microsoft 365 addresses when properly configured.

Yes, we use Microsoft Purview to track your alignment with frameworks like NIST, ISO 27001, and HIPAA, generating audit-ready reports showing implemented controls and compliance status.

We provide pre-audit security reviews, gap analysis, and remediation roadmaps to ensure you’re prepared before auditors arrive.

Several clients use our continuous compliance monitoring for their annual audits, maintaining ongoing compliance rather than scrambling before each audit cycle.

No, when implemented in proper sequence with phased rollout and user training before enforcement. MFA setup requires users to authenticate once per device then work normally. Conditional Access policies are tested with small groups first and configured to warn before blocking. DLP policies notify users about policy violations with option to explain business need rather than immediately blocking legitimate work. Intune device enrollment happens during scheduled maintenance windows with security baselines applied gradually. Our layered implementation approach (identity → devices → access control → data protection) minimizes disruption by ensuring each security control works properly before adding the next layer.

No. We handle complete migrations from on-premises email servers, Google Workspace, GoDaddy, Rackspace or other platforms. Our certified Microsoft specialists ensure smooth transitions with minimal disruption—typically 1-2 days for small teams with full data transfer and security configuration.

We implement critical security controls within 1-2 weeks using a phased approach. Basic protections (MFA, conditional access) deploy in days, while comprehensive security transformation (DLP, Information Protection, Zero Trust) typically completes within 1-3 months depending on complexity.

Ongoing management includes security monitoring, Secure Score optimization, license management, user support, a video training library for your staff, IT inventory tools, policy updates as threats evolve, and strategic guidance.
