Global Admin Access Is Wide Open
Too many accounts hold global administrator rights, any one of which is a single point of failure.
We harden the tenant and restrict global administrative access to who actually needs it.

Microsoft 365,
Actually Locked Down.
Tenant hardening, collaboration controls, advanced email threat protection, and SPF/DKIM/DMARC - because being on Microsoft 365 isn't the same as being secure on it.
Default M365 settings are built for convenience, not security. We reconfigure your tenant around how it's actually being used.

Why This Layer Matters
The Gaps We Find Most Often
These are the specific gaps we see most often in this area when we audit a client's environment, and what we do about each one.
Sharing Permissions Are Wide Open
Anyone can share a SharePoint folder or OneDrive file externally with a single click - and nobody's tracking it.
We lock down collaboration controls across SharePoint, OneDrive, and Teams external chat.
Phishing Emails Bypass Native Filters
Microsoft's built-in filtering catches the obvious spam, not the convincing impersonation attempts targeting your finance team.
We deploy advanced email threat protection layered on top of native filtering.
Your Domain Can Be Spoofed
Without SPF, DKIM, and DMARC properly configured, attackers can send email that appears to come from your own domain.
We configure and monitor SPF, DKIM, and DMARC on an ongoing basis.

Common Questions
Cloud & Workspace Security FAQ
What business owners and IT managers ask about this layer of managed security.
We're already on Microsoft 365 - isn't it secure by default?
Default settings favour convenience over security - wide-open sharing, minimal email authentication, and unrestricted admin access are all common out of the box.
Will locking down sharing stop us collaborating with clients?
No. Controlled external sharing stays possible - it's governed and tracked rather than wide open.
What's the difference between SPF, DKIM, and DMARC?
SPF lists which servers can send mail for your domain. DKIM cryptographically signs outgoing mail. DMARC tells receiving servers what to do when a message fails those checks - together they stop domain spoofing.
Do we need to buy new software for this?
Mostly configuration of what you already have in Microsoft 365, plus an optional third-party email gateway where native filtering isn't enough.
Will this affect Teams for external partners?
External chat is restricted and governed, not blocked outright - genuine business needs are accommodated during setup.
How do we get started?
Schedule a security audit. We'll review your tenant configuration and propose what needs tightening.
