How Pricing Works

Each Microsoft 365 tenancy audit is £250. This includes a comprehensive security review of your tenant configuration, user settings, and security policies. Optional remediation hours are available at £85 per hour to help fix any security issues we find.

What Drives Microsoft 365 Security Audit Pricing

What actually drives the price up or down?

Your price is based on a few simple factors:

How many Microsoft 365 tenancies you have

  • Most companies have just one tenancy, but some have multiple (e.g. after acquisitions or for different business units).
  • Each tenancy is audited separately at £250 per tenancy.

Do you want us to fix problems we find?

Just tell me what's wrong We audit your Microsoft 365 settings, report issues, and you or your IT team fix them
Find AND fix for me We audit, report issues, AND help fix them (adds expert hours at £85/hour to your package)

In simple terms: One tenancy, one price. Need help fixing what we find? Add some expert hours. We only charge for what you actually need.

What's Not Included

What's not included

To keep pricing clear and fair, some things are not included by default:

  • Full penetration testing

    Human-led attempts to break in – that's a separate service

  • Major remediation projects

    e.g. migrating servers, redesigning networks, system patching and hardening

  • Ongoing managed IT support

    We're happy to work alongside your existing IT partner or in-house IT department

  • On-site visits

    If required, we'd need to discuss this in the scoping session

Is a Microsoft 365 Security Audit Worth the Cost?

Is a Microsoft 365 Security Audit worth the cost?

A rough way to look at it:

£

A compromised Microsoft 365 account can cost many times more than an audit – in data theft, business email compromise, regulatory fines, and reputational damage.

A security audit doesn't guarantee you'll never be attacked, but it identifies weak spots in your Microsoft 365 security posture: misconfigured settings, missing protections, and risky user permissions.

A Simple Comparison

Think of it like a health check: you might feel fine, but wouldn't you want to know if something's not quite right before it becomes a serious problem?

The real question isn't "Can we afford a Microsoft 365 Security Audit?"
It's "Can we afford not to know how secure our Microsoft 365 environment really is?"

Can we just do a one-off scan?

Yes. They’re helpful if you:

- Need a snapshot for an audit or insurance

- Are about to make a major change and want a health check

Most clients move to ongoing scanning once they see how much changes over time.

Do prices ever increase?

We keep pricing simple and predictable. Prices might change if:

- You add significantly more systems or locations

- You want to increase scan frequency or widen the scope

- If you would like us to help with Remediation

We’ll always discuss any change in advance, so you’re never surprised.

Can you work with our existing IT provider?

Absolutely. In fact, that’s very common.

We:

- Provide them with clear, prioritised actions

- Stay available to answer questions about the findings

- Avoid blame – the focus is on fixing issues and reducing your risk

How do we get an exact quote?

Four steps:

How many Microsoft Tenancies are in scope
Fewer servers and devices cost less than multiple offices, data centres and cloud accounts.

How much help you want with remediation
If you, your internal IT team or your IT provider handle fixes, you’re mainly paying for scanning and reporting.
If you’d like us to help remediate, that’s extra project work, priced separately.

Are there any hidden fees or surprise extras?

No. Everything is clearly priced and agreed up front. If anything outside the original scope is needed, we’ll explain it first and get your approval before doing the work.

What if my needs change after we start working together?

That’s totally fine. You can scale your service up or down as you grow. We’ll review things with you regularly so you’re never stuck paying for something you don’t need.

Am I tied into a 12- or 24-month contract?

No. There’s no long-term lock-in. You can stop or change the service if it’s not working for you – we prefer to earn your trust, not trap you in a contract.

What if the scan finds loads of issues — does that mean a huge extra bill?

The cost of the scan itself doesn’t change, no matter how many issues are found. If you’d like help fixing them, we’ll give you clear, prioritised options and prices so you stay in control of what gets done and when.

Can we start with a one-off scan before committing to ongoing scanning?

Yes. Many clients start with a one-off assessment to see where they stand. If you like how we work, you can then move to regular scanning to keep on top of new vulnerabilities.
