Microsoft Hardening
Microsoft 365, locked down the way it should have shipped
Out of the box, Microsoft 365 leaves your business exposed. We enforce 100+ security policies, close the gaps, and keep watch — so your data, email and identities stay protected.
The default problem
Secure by default? Not quite.
Microsoft 365 is powerful — but its default settings prioritise ease of setup over security. Multi-factor authentication often isn’t enforced, anyone can sign in from any device anywhere, legacy protocols stay open, and there’s nothing stopping sensitive data being emailed out.
Microsoft protects the platform. Protecting what’s inside your tenant — your accounts, email and files — is down to how it’s configured. Most businesses never change those defaults.
Our hardening service brings your tenant up to a proven security baseline: over a hundred policies enforced, continuously monitored for drift, and reported against recognised benchmarks — for businesses across Surrey, London and the South East.
What you get
From exposed to enforced
MFA everywhere
Multi-factor authentication enforced across every account — the single biggest win against account takeover.
Conditional access
Only trusted people, on trusted devices, in expected locations reach your data. Risky sign-ins blocked.
Legacy auth blocked
We shut down the old, insecure protocols attackers exploit to bypass MFA.
Data loss prevention
Rules across email, Teams and SharePoint stop sensitive data leaving by accident or design.
Backup for 365
Independent backup of your mailboxes, files and Teams — because Microsoft doesn’t do it for you.
Drift monitoring
Continuous checks so your security posture doesn’t quietly slip over time.

Questions
Frequently asked
What does “hardening” Microsoft 365 actually mean?
It means changing the default configuration to a secure one — enforcing MFA, restricting sign-ins, blocking legacy protocols, adding data loss prevention and more. The goal is to close the gaps attackers rely on, without getting in the way of your team’s work.
Will locking things down make Microsoft 365 harder to use?
Done well, no. We apply security in a way that’s invisible for legitimate users — they simply sign in as normal (with MFA), while risky and unauthorised access is blocked in the background.
Doesn’t Microsoft back up my data already?
Microsoft keeps the platform available, but it does not provide comprehensive backup of your data — accidental or malicious deletion is your responsibility. We add independent, tested backup as part of hardening.
How is this different from Cyber Essentials?
Cyber Essentials certifies a baseline; hardening is the hands-on work of configuring Microsoft 365 to a strong security standard. They complement each other — many clients harden their tenant and then certify.
