Choosing the right service
Which service fits our situation?
That can be narrowed down in an initial consultation. If your current security posture is unclear, a Microsoft Security Assessment is often a good structured starting point.
Can individual services be commissioned separately?
Yes. Assessment, Entra ID, Defender, Purview, Copilot, Agent 365, or CSP can be looked at individually or sensibly combined, depending on your objectives.
Does ReByteIT also support technical implementation?
Yes. The implementation of recommended measures can be agreed separately after the analysis. The scope of work and responsibilities are defined transparently.
From a concrete risk to the right Microsoft security service
A sound choice starts with the situation, not with a product name: do you first need an independent view of the current security posture, a targeted fix for a known weakness, or a controlled rollout of a new Microsoft service? That determines whether an assessment, product-specific consulting, or technical implementation is the right starting point.
If several goals overlap, dependencies are made visible and then prioritized. Identities and access often provide the foundation before endpoints, data, or AI services follow. This creates a clear roadmap instead of a collection of isolated measures. During the initial consultation, we clarify the objective, existing environment, decision needs, and desired scope so that the appropriate service can be defined unambiguously.
Which Microsoft security service fits your company?
In a free and non-binding initial consultation, we clarify your current situation and the next sensible step.
