Every user, mailbox, file, license and security setting your company has in Microsoft 365 lives in one place: your tenant. When it's set up right, everything on top of it — email, Teams, SharePoint — is secure and easy to manage. As a Microsoft Cloud Solution Provider (CSP), ECSG licenses, configures, secures and manages your tenant from day one.
A tenant is your company's private space inside Microsoft's cloud. Microsoft keeps the building running and secure. Who gets in, what they can open and how the doors are locked is configured inside your tenant — and that's where most security gaps begin or end.
Every person, their sign-in, their MFA and the groups they belong to.

Microsoft Defender XDRAs a Microsoft Cloud Solution Provider (CSP), ECSG provides your Microsoft 365 licenses directly. You get one point of contact for licensing and support, and a partner who makes sure you're not paying for more — or protected by less — than you need.
| Business plan | What it includes | Best for |
|---|---|---|
| Microsoft 365 Business Basic | Email on your domain, Teams, SharePoint, OneDrive and the web and mobile versions of Word, Excel and PowerPoint. | Teams that work mostly in the browser or on mobile. |
| Microsoft 365 Business Standard | Everything in Basic, plus the desktop apps (Word, Excel, PowerPoint, Outlook) on computers. | Office staff who live in the desktop apps. |
| Microsoft 365 Business Premium | Everything in Standard, plus advanced security: Defender for Business, Defender for Office 365, Intune device management, Conditional Access and information protection. | Businesses that handle sensitive data or want the strongest built-in security. |
| Add-ons | Microsoft 365 Copilot, Teams Phone, extra storage, email-only plans and more. | Specific roles and needs. |
Microsoft 365 business plans support up to 300 users. Plans and features change over time — we confirm the current options with you before any purchase.
Your licenses come through ECSG, alongside the team that manages them.
We review licenses regularly and remove or reassign the ones nobody uses — especially after departures.
Not everyone needs the same license. Office staff, field workers and executives can each get the right plan.
Microsoft 365 includes powerful security — but much of it has to be turned on and tuned. Microsoft Defender XDR brings together protection for email, devices, identities and cloud apps, and connects related alerts into a single incident. ECSG applies a security baseline to every tenant we manage.
A stolen password alone is no longer enough to get in.
Old protocols that can't use MFA are shut off — a common way attackers bypass it.
Sign-in rules based on user, device, location and risk (with Business Premium).
Separate admin accounts, least-privilege roles and extra protection for the keys to the tenant.
Anti-phishing, impersonation protection, Safe Links and Safe Attachments with Defender for Office 365.
Defender for Business and Intune policies for company computers and phones (with Business Premium).
Clear rules for sharing files and inviting guests from outside the company.
Activity logging turned on and Microsoft Secure Score reviewed to track improvement over time.
Built-in plus specialized: Microsoft's built-in protection is the foundation. Where a business needs more, we add specialized layers like Proofpoint for email and SentinelOne for devices — and monitor everything 24/7. See our cybersecurity stack →
Your tenant starts with a technical address like yourcompany.onmicrosoft.com. We connect your own domain so email, Teams and sign-ins all carry your brand — with the DNS records set correctly from the start.
We verify your domain in Microsoft 365 and make it the default for every user.
MX, Autodiscover, SPF, DKIM and DMARC configured so email is delivered — and can't be faked.
Several domains in one tenant — for different brands, regions or a company name change.
We move email, calendars, contacts and files without losing history and with minimal disruption to your team.
Mailboxes, calendars, contacts and Drive files moved to Exchange, OneDrive and SharePoint.
Microsoft 365 bought through GoDaddy is moved to direct management under ECSG as your CSP.
Users, mail and files moved between tenants when companies merge, split or rebrand.
On-site file shares and legacy email moved into SharePoint, OneDrive and Exchange Online.
Users, mailboxes, data volume, domains and current licenses.
InventoryTenant, licenses and security baseline ready before anyone moves.
Secure from day oneEmail and files copied in stages while your team keeps working.
Staged copyDomain records switched outside business hours, with first-day support.
MX switchOld accounts closed, licenses right-sized and your team trained.
OptimizeA Cloud Solution Provider is a Microsoft partner authorized to sell and manage Microsoft cloud licenses directly. Buying through ECSG means your licenses, configuration and support come from the same team.
Yes. We can transfer your licenses and administration to ECSG — including tenants originally set up through GoDaddy — without moving your data out of Microsoft 365.
Microsoft secures its infrastructure, and some protections are on by default. Many important settings — MFA enforcement, Conditional Access, admin protection, email policies, sharing rules — must be configured for your business. That's what our baseline does.
Not always. It's the best choice for businesses that handle sensitive information or want advanced built-in security. We often mix plans by role so you get protection where it matters and save where it doesn't.
We migrate in stages and switch your domain outside business hours, so your team keeps working and starts the next day in Microsoft 365 with their history intact.
We'll review your licenses, domains, sign-in policies and security settings, then explain in plain language what we'd fix first. No obligation.
Secure. Reliable. Human.
