Simplify your Microsoft 365 Security

Managed Services for securing your Microsoft 365 tenant and Defender applications

Secure your Microsoft 365 environment with Secure365.
Securing your Microsoft 365 environment can be an overwhelming task without the right knowledge and expertise, processes or a trusted partner who specialises in Microsoft security.

Securing Microsoft 365 presents several challenges to most organisations

  • The open nature of Microsoft security means it is very flexible but can be left unsecured.
  • There are not many automated options or settings available, meaning that many recommended settings need to be configured manually or require deep technical knowledge to implement correctly.
  • There are a lot of recommendations from different wellknown sources such as Microsoft and CIS but none of them are comprehensive and nothing beats industry experience to get it right.
  • There are interdependencies between certain settings and feature setups that affect other security settings and features in the Microsoft tenant. Implementing without planning could lead to unintended security holes.

Combining the power of our innovative SaaS-based approach with our team of Microsoft security experts, DEFEND is uniquely positioned to help secure your Microsoft 365 environment simply and cost-effectively with our Secure365 Managed Services offerings:

Secure365 Essentials gives you the confidence that your Microsoft 365 security is optimally configured to protect your business, combining a Microsoft 365 security blueprint tailored to your organisation and compliance needs with our innovative SaaS-based configuration review approach.

Extend your Essentials service with Secure365 Premium providing support for your team in day-to-day operations of your Microsoft 365 tenant and Defender applications with regular health-checks and proactive reviews to ensure effective protection, identify improvement opportunities and assess new features.

Secure365 Blueprint

At the core of Secure365 is the DEFEND Secure365 Blueprint, a living, continually updated set of security configuration settings for the Microsoft 365 environment and features. The Blueprint has recommended settings that can be linked back to configuration standards from published baselines such as Microsoft, CIS or NIST, as well as knowledge from DEFEND’s own experience and best practice.

Each of the Blueprint settings are accompanied by details as to why it is recommended, reference links to source baselines standards and controls, implementation instructions, automation scripting, operational considerations, change notes and regular tasks associated with maintaining control effectiveness.
