Microsoft 365
Microsoft 365 Security
Almost every business we assess is already paying for security features it has never switched on. Microsoft 365 ships configured for a smooth first day, not a hostile internet.
The problem
The defaults are not a security posture
A new tenant permits legacy authentication that bypasses MFA, lets any user consent to third-party apps reaching company mail, allows mailbox forwarding to external addresses, and keeps audit logging shallow. None of that is a flaw in the product — it is a set of choices nobody was asked to make, and attackers know the defaults better than most administrators do.
Our approach
A reviewed, documented tenant configuration
We assess the tenant against what actually gets exploited, agree what to change with you rather than at you, then implement it and write it down. You get a configuration you can hand to an auditor or an insurer, and a list of what we deliberately did not change and why.
What you get
Included as standard
Not an upsell list. These are the things that make the difference between a service you pay for and a service that works.
- Conditional Access replacing blanket MFA prompts
- Legacy authentication blocked — the bypass many breaches still use
- External mailbox forwarding restricted and monitored
- Third-party app consent taken out of end-user hands
- Unified audit logging on, with retention that survives an investigation
- Admin roles reduced and made temporary rather than permanent
- Defender policies for phishing and malicious attachments
- A written record of the configuration and its exceptions
How we work
What actually happens
- 1
Assess
Read the tenant as it stands and score it against the settings that matter. No changes yet.
- 2
Agree
Walk through findings in plain language, with the business impact of each change stated before it happens.
- 3
Implement
Change in stages, starting with what breaks nothing. Pilot groups before tenant-wide enforcement.
- 4
Document
Write down the end state and the exceptions, so the next person inherits a decision rather than a mystery.

Questions
M365 Security questions
We already have MFA switched on. Is that not enough?
It is the single best thing you can do, and it is not sufficient on its own. If legacy authentication is still permitted, there are protocols that never see the MFA prompt at all. Attackers look specifically for that gap, and both MFA fatigue and token theft work around a prompt that is otherwise correctly configured.
Will this stop people working?
It should not, and that is a design constraint rather than a hope. Conditional Access is the tool that lets you be strict about risky sign-ins while staying unobtrusive for a known person on a known device. Changes go to a pilot group first.
Do we need a more expensive licence?
Sometimes, and we will say so plainly rather than quietly assuming it. A good deal of hardening is available on Business Premium, which many businesses already hold without using. Where a feature genuinely needs a higher tier, you get the cost and the reason before anything is bought.
Can you assess our tenant without taking over our IT?
Yes. The assessment is a standalone engagement, and several businesses use it as a second opinion on work an existing provider has done.
