Microsoft 365 Common Challenges & Complexity
Microsoft 365 is a market-leading platform that offers unparalleled potential to empower collaboration, enhance productivity and secure your organisation. However, many businesses struggle to fully realise these benefits due to the following challenges:
Complex Technology
The vast Microsoft 365 suite requires deep expertise to configure and manage effectively, ensuring all features are fully leveraged.
Uncontrolled Shadow IT
Employees using unauthorised apps increase the attack surface and risk of data breaches
Limited Technical Resources
Organisations often lack the specialised knowledge and bandwidth to secure, optimise and maintain Microsoft 365, especially when stretched or focused on other critical projects.
Evolving Technology
Frequent updates and new capabilities make it difficult to stay current and avoid configuration drift.
Insider Threats
Malicious or negligent insider risks are often overlooked or not sufficiently mitigated.
Unsecured Emerging Technologies
Innovations like AI introduce new security challenges that demand proactive management.
Misalignment with Best Practices
Deviating from Microsoft-recommended configurations weakens security and can leave organisations vulnerable.
Security Awareness Gap
Employees may not fully understand or use available security features, increasing the risk of human error.
Complex Migration
Migrating to and maintaining Microsoft 365 technologies requires significant expertise and resources.
