Microsoft security
Microsoft security services that decide what people, and AI, can reach
Identity, email and app, endpoint and data protection configured in the Microsoft 365 you already license, so attacks are stopped and AI assistants only see what each user should.
Free · about one week · read-only
Most organizations already own the controls. We switch them on properly.

Short answer
Communication Square configures Microsoft security for businesses and public agencies: identity protection with Entra ID, email and app protection with Defender for Office 365, endpoint protection with Defender for Endpoint and Intune, and data protection with Purview sensitivity labels and data loss prevention. The same controls decide what Copilot and other AI assistants can reach.
Starting points
Where Microsoft security services usually start
The cost of waiting
Breaches cost more when AI is ungoverned
What it really is
Security you own is not security you have
Most Microsoft 365 plans already include strong controls. The gap is configuration: switched off, half set up or never tuned.
Your options
Leave the defaults, buy another tool, or configure what you own
The cheapest security improvement is usually the one already in your license.
| Microsoft defaults | Add a third-party tool | Configure what you own (us) | |
|---|---|---|---|
| Cost | Included | Another subscription | Included licenses, fixed-price setup |
| Coverage | Partial | One area | Identity, email, endpoint and data |
| AI exposure | Not addressed | Rarely | Labels and DLP decide what AI can reach |
| Monitoring | None | Vendor console | Managed service option, monthly report |
| Government cloud | Varies | Often unsupported | GCC and GCC High delivered |

Our approach
From findings to configured controls
- AssessRead-only review of identity, email, endpoint and data settings.
- PlanRanked fixes with user impact and a fixed price.
- ConfigureControls switched on in stages, piloted with a small group first.
- Hand overDocumentation, admin training and optional monitoring.
Our promise: every change is piloted before it reaches everyone, and documented so your team can see exactly what was set.
AI on this foundation
The controls that decide what AI can reach
Copilot and every AI assistant inherit the permissions and labels in your tenant. Getting security right is most of getting AI right.

Common questions
Microsoft security services: questions buyers search for
Does Microsoft 365 include security?
Yes. Every Microsoft 365 plan includes core protection such as multifactor authentication and email filtering, and plans such as Business Premium, E3 and E5 add Defender, Intune and Purview controls. Most organizations already own more security than they have switched on; our Microsoft security services configure what your licenses include before suggesting anything new.
What does a Microsoft 365 security assessment cover?
Our free Microsoft 365 security assessment is read-only and takes about a week. It reviews identity (MFA and conditional access), email protection, device compliance and how widely data is shared, against what your licenses include, and ends with a ranked fix list and a fixed price for each fix.
Are you a Microsoft Defender implementation partner?
Yes. We deploy Defender for Office 365 as part of identity and email protection (2 to 3 weeks) and Defender for Endpoint with Intune policies (about 3 weeks), then tune alerts so someone acts on them. Ongoing monitoring is available under managed services.
Questions buyers ask
Before you decide
Do we need to buy Microsoft 365 E5?
Not always. Many controls are in Business Premium and E3. The assessment shows what your current licenses include and where an upgrade would pay for itself.
Will MFA and conditional access disrupt staff?
We pilot with a small group, communicate changes in advance and roll out in stages, so staff see one short prompt rather than a lockout.
Can you work in GCC or GCC High?
Yes. We are an AOS-G partner and configure security in government clouds.
Is this a one-off project or ongoing?
Either. Configuration is a fixed-price project; monitoring afterwards is optional under AI-powered managed services.
