Microsoft 365 Security & Optimisation: Essential Steps for SMBs
For small to medium-sized businesses (SMBs) without a dedicated IT department, Microsoft 365 (M365) is a game-changer for productivity. However, like any tech tool, it comes with risks that need proactive management.
From data loss to security vulnerabilities, unprotected M365 environments can disrupt operations and expose sensitive information. Many businesses rely on generic best practices, but there are critical steps often overlooked that can significantly enhance security and efficiency.
At Dead Simple Computing, we specialize in Microsoft 365 Solutions and Managed IT Services to ensure businesses get the most out of their M365 investment. Here’s what you need to do to secure and optimize your Microsoft 365 environment.
1. Check Your Licenses – Are You Overpaying or Under-Protected?
One common mistake businesses make is mismanaging M365 licenses. This is not just about overpaying but also about ensuring employees have the right level of access and security features.
What You Should Do:
- Regularly audit your M365 licenses to match each employee’s role and avoid unnecessary costs.
- Utilize advanced security features available in premium licenses, such as data encryption and compliance tools.
- Leverage Dead Simple Computing’s license audit service to optimize costs and ensure you’re not underutilizing critical security features.
2. MFA is a Must – But Don’t Stop There
Multi-factor authentication (MFA) is a fundamental security layer, but threats are becoming more sophisticated. Relying solely on MFA isn’t enough.
What You Should Do:
- Combine MFA with proactive threat monitoring. Dead Simple Computing offers Managed Detection and Response (MDR) for M365 to monitor suspicious activities.
- Set up Conditional Access Policies to restrict access based on location, device type, and risk level.
- Deploy advanced monitoring rules to prevent unauthorized access attempts before they escalate.
3. Is Microsoft Defender Fully Configured?
Microsoft Defender provides built-in security, but it’s often underconfigured, leaving businesses vulnerable to cyber threats.
What You Should Do:
- Ensure Microsoft Defender is fully optimized for endpoint protection, email security, and cloud monitoring.
- Use Endpoint Detection and Response (EDR) to enhance threat detection.
- Implement Data Loss Prevention (DLP) policies to prevent sensitive information from leaking outside your organization.
- Partner with Dead Simple Computing to configure and monitor M365 security solutions for ongoing protection.
4. Go Beyond Basic Phishing Training
Phishing attacks remain a leading cause of business breaches. While training employees is essential, advanced anti-phishing measures are equally important.
What You Should Do:
- Enable Microsoft’s advanced phishing protection tools to block threats before they reach inboxes.
- Use AI-driven phishing detection to identify and quarantine malicious emails automatically.
- Conduct phishing simulations to keep employees prepared.
- Implement real-time threat response with Dead Simple Computing’s Incident Response Services.
5. Data Governance and Backup: Essential, Yet Often Overlooked
Many businesses assume that because their data is in the cloud, it’s safe. However, Microsoft 365’s built-in backup is not sufficient for long-term protection.
What You Should Do:
- Implement retention policies to meet compliance requirements.
- Ensure robust backup solutions are in place for disaster recovery.
- Use third-party backup solutions to protect against accidental deletions and ransomware attacks.
- Leverage Dead Simple Computing’s Backup & Disaster Recovery services for complete data protection.
6. Optimize Performance & Efficiency with Built-in Analytics
Beyond security, M365 provides insights that help optimize your business operations. However, many businesses don’t take full advantage of these tools.
What You Should Do:
- Use Microsoft 365 Analytics to identify inefficiencies and training needs.
- Monitor Secure Score to ensure your security posture remains strong.
- Set up customized alerts for abnormal usage patterns.
- Work with Dead Simple Computing to continuously optimize your business processes and IT infrastructure.
