Microsoft 365 Security Audit

See exactly how secure your Microsoft 365 really is – through the eyes of an ethical hacker.

What this audit actually does

This isn’t a generic “health check” or a bit of light box-ticking.

Your Microsoft 365 Security Audit is a focused review of how your M365 tenant is set up today – led by an ethical hacker, using professional, state-of-the-art security tools to uncover the gaps attackers love.

You’ll walk away with:

Microsoft 365 Security Posture Score - Compact

A straightforward security posture score for Microsoft 365

  • ✓ Clear view of exposures & strengths
  • ✓ Prioritised fixes - know what's urgent
  • ✓ Plain English for leadership & IT

On this page we answer the key questions you’d naturally ask before booking – what it is, what you get, how it works, and whether it’s right for you.

Microsoft 365 Security Assessment Details

What I look at inside your Microsoft 365

Your Microsoft 365 security posture score comes from a full set of checks that run across your tenant – not just a quick look at MFA and a couple of switches.

Using my ethical hacking mindset and professional tools, I review how Microsoft 365 is configured and used, and score you across key areas like these:

1 Accounts, sign-ins & MFA
▼
  • Are admin and user accounts protected by MFA?
  • Is legacy / basic authentication blocked where it should be?
  • Are there inactive or "forgotten" accounts that could be abused?
  • Are passwords and lockout policies set sensibly, not just "default"?
2 Phishing-resistant sign-in
▼
  • Are strong, phishing-resistant methods available (like security keys or modern app-based sign-in)?
  • Are the weakest MFA methods (SMS / voice) still allowed?
  • Do prompts show context like app name or location so staff can spot dodgy requests?
3 Email security & message limits
▼
  • How well are spam, phishing and malware filtered and quarantined?
  • Are Safe Links / Safe Attachments and zero-hour auto-purge (ZAP) in place?
  • Are dangerous "allow lists" and IP bypasses disabled?
  • Are sensible limits in place so a compromised account can't blast thousands of emails in minutes?
4 Domain protection (SPF, DKIM, DMARC)
▼
  • Are your domains protected against spoofing so attackers can't easily fake your email?
  • Are DKIM and DMARC configured properly, not just "half done"?
5 Data sharing, guests & external access
▼
  • How is external sharing handled in SharePoint, OneDrive and Teams?
  • Can guests or external users reshare data freely, or are they controlled?
  • Are calendar, contacts and other information shared safely by default?
6 Admins, privileged roles & approvals
▼
  • How many people really have high-level admin rights?
  • Are privileged roles managed through just-in-time access, or permanently "on"?
  • Are there proper "break glass" and emergency accounts rather than risky workarounds?
  • Can normal users add risky apps, or does admin approval step in?
7 Devices, sessions & conditional access
▼
  • Do admins have to use trusted / compliant devices?
  • Are unmanaged devices restricted or treated differently?
  • Are risky sign-ins, risky users and risky locations handled automatically by policy?
8 Monitoring, logs & self-service
▼
  • Is the unified audit log and mailbox auditing turned on so we can see what happened if there's an incident?
  • Can users safely reset their own passwords without going through IT every time?
  • Can users easily report suspicious sign-in prompts?

M365 Security Audit - Good Fit

Who this is a good fit for

This Microsoft 365 Security Audit is ideal if:

  • Your business runs heavily on Microsoft 365 (email, Teams, SharePoint, OneDrive)
  • You suspect it was "set up once and left" by IT or a previous provider
  • You want a clear, independent view of risk – not just "you're fine"
  • You need something you can put in front of directors or owners that actually makes sense

How the process works

How the Process Works

I like to keep this simple and transparent:

1

Read the site to get informed

Start by reading this page (and the rest of the site) so you understand what the Microsoft 365 Security Audit is, what you get, and who it's for. The more informed you are, the better your decisions will be.

2

Get an instant quote on the pricing page

When you're ready, head over to the pricing page to see exactly what this service will cost. No vague "contact us for pricing" – you get a clear, instant quote.

3

Happy with the quote? Schedule a consultation

If the price and service look like a good fit, click Schedule Consultation and fill in the short form. This gives me the basics I need before we speak.

4

I'll contact you back

I'll get in touch to answer your questions, confirm the details, and agree next steps if you want to go ahead.

Is this just you running a tool and printing a report?

No. I use professional security tools to collect the data, but the value is in the ethical hacker review. I go through your setup like an attacker would, explain what actually matters, and turn it into a clear action plan.

How is this different from what our IT provider already does?

Most IT teams focus on “keeping things working” – email flows, users can log in, files sync. This audit focuses on “how easy would it be to break in or do damage?” It’s a security-first review, not a general health check or support ticket.

Will you be changing any of our settings during the audit?

No. The audit is read-only. I look at how Microsoft 365 is configured today and highlight the gaps. Any changes are agreed with you (and your IT team/provider) afterwards.

Do you need our passwords or access to people’s emails?

No. I don’t need anyone’s password, and I don’t read individual emails or private content. I look at security settings, permissions and configuration – not the content of your inboxes.

Will this disrupt staff or cause downtime?

No. The tools run quietly in the background. Your team won’t notice anything happening and can carry on working as normal.

Do we really need this if we already have MFA turned on?

MFA is a big step in the right direction, but it’s not the whole story. I often find issues around old accounts, over-privileged access, weak email protection and risky sharing – even in companies that already use MFA.

What do we actually walk away with at the end?

You get a clear security posture score, a prioritised list of risks, and a practical, step-by-step action plan. You can hand it to your IT team/provider or ask me to help implement it.

Will I need to give you access to our Microsoft 365 tenancy?

Yes – I’ll need secure, limited access so I can review how things are configured. We’ll go through the ins and outs together on the call first, including exactly what I can see, what I can’t see, and how access is set up and removed once the audit is complete.

Independent cyber security · Sussex & UK-wide

Who checks that your security actually works?

Your IT team keeps the business running. We check it is protected — finding the risks, telling your IT team what to fix, and showing you the proof every month in plain English.

Prices published — no sales call needed No lock-in, 30 days' notice Only 20 managed clients
QuantumCare starts at
£35 /month

Per computer, sole trader. Excludes VAT.

  • Round-the-clock monitoring of every computer
  • Updates, ransomware protection, web filtering
  • Training so your people spot the scams

Three packages, sized by how many people you have — £35, £204 and £710 a month. Every price is on this page.

What Systems Secure is

Systems Secure Ltd is an independent cyber security company based in Copthorne, West Sussex, run by James Batt and working with businesses across the UK. Its managed service, QuantumCare, works alongside your existing IT support rather than replacing it — finding the risks, telling your IT team what to fix, and checking that important protections are still working.

This is cyber security, not IT support. Prices are published on this site, starting at £35 a month. Cyber security should give you clear answers — not long reports, confusing alerts or guesswork.

Working alongside your IT team

Keep your IT support. Add dedicated cyber security.

There's a reason a company's accounts are prepared by one firm and audited by another. It isn't that accountants can't be trusted — it's that nobody, however good, is well placed to check their own work.

Your IT team

Keeps your systems, users and everyday technology running. In-house or outsourced, they stay involved throughout — and receive clear, specific actions from us whenever their help is needed.

Systems Secure

Finds the cyber risks, strengthens protection, and checks that important security controls are still working. You get an independent view of what's protected, what has changed, and what should happen next.

  • We're not here to replace anyone or catch anyone out
  • Clear responsibilities for everyone involved
  • Independent checks on important protection
  • Clear proof for you every month

Good IT teams tend to welcome this. An independent report is often the evidence they've been trying to get budget on for months.

STEP 1

Pick your package

Three QuantumCare packages, sized by how many people you have, from £35 a month. Every price is published on this site.

STEP 2

Thirty minutes with James

A conversation, not a pitch. We confirm which package fits — and if the honest answer is that you don't need us, we'll say so.

STEP 3

Setup

We install it, configure it and check it is working — usually inside a week from agreement, and mostly without you noticing.

STEP 4

Every month after

Monitoring, updates applied in the background, and problems dealt with rather than just flagged up. Micro Business and Business Pro add a plain-English summary each month.

Straight dealing

What you can hold us to

No lock-in

Month to month on 30 days' notice, no setup fee and no penalty for changing your mind. A 12-month option is there if you'd rather freeze your price — a choice, not a requirement.

A three-month refund

If your business is compromised while you're following the agreed security plan, you get three months' fees back. No security company can promise you'll never be attacked, and we don't.

Only 20 clients

The managed security list is capped at 20, so the person checking your security is actually paying attention — and you deal with the same person every time.

Never your competitor

We will not take on a direct competitor of an existing client, and every price on this site is the price you pay.

Who you'll be working with

Hi, I'm James Batt

James Batt Founder, Systems Secure Ltd
  • CISSP, C|CISO, CEH, NCSP Practitioner, Security+
  • 21 years designing multi-million-dollar IT systems in oil and gas
  • 16 years running Systems Secure, based in Copthorne, West Sussex

Most cyber security experts talk in acronyms. I talk like a business owner — because I am one.

I went into the oil and gas industry in 1995, doing IT, networks and security for global corporations, and led multi-million-dollar projects across America and Europe. Twenty-one years of it — and security was part of the job from the first day. I'm not an IT man who retrained into it later.

In 2010 I started Systems Secure as a sideline and ran it alongside the day job for six years. By 2016 it had outgrown the evenings and weekends, so I sat the Certified Ethical Hacker exam, left a good salary and better benefits behind, and turned the company from IT to cyber security — because security was, and still is, the weakness most smaller businesses have.

Sixteen years on, I've helped 200+ UK organisations strengthen their defences, pass compliance audits, and sleep easier knowing their data — and their reputation — are protected. You deal with me, not a rotating support desk.

Questions you're probably asking

The main ones that come up on almost every call, answered here so you don't have to book one to find out.

How much does cyber security cost for a small business in the UK?

Systems Secure managed cyber security starts at £35 per computer per month for a sole trader, £204 per month for a business of one to nine people, and £710 per month for a business of ten or more. All prices exclude VAT and there are no setup fees.

What you pay depends on how many people you have. The Sole Trader package is priced per computer. Micro Business and Business Pro are priced per Microsoft 365 or Google account, so the cost scales with your team rather than a fixed licence block. Every price is published on the website — you don't need to sit through a sales call to find out the number.

What is QuantumCare?

QuantumCare is Systems Secure's cyber security service: three managed packages priced by how many people you have — Sole Trader from £35 a month, Micro Business from £204 and Business Pro from £710 — plus QuantumCare CISO, a separate service from £1,200 a month for businesses of 10 to 250 that need a qualified security officer rather than more software.

It is cyber security, not IT support — it works alongside whoever runs your systems rather than replacing them, finding the risks, telling your IT team what to fix, and checking that important protections are still working.

Do I have to sign a long contract?

No. Every Systems Secure package runs on a rolling monthly basis with 30 days' notice and no cancellation penalty. There is no minimum term.

A 12-month option is available if you'd rather freeze your price, which saves £2 per account per month. It's a choice, not a requirement.

Is there a setup fee?

No. There are no setup fees and nothing to pay upfront on any Systems Secure package. You pay monthly, starting from the month the service begins.

Do your prices include VAT?

No. All Systems Secure prices are quoted excluding VAT. VAT is added to your invoice at the prevailing UK rate.

Can I get a one-off piece of work instead of a monthly plan?

Yes. Fixed-price consulting is available with no ongoing commitment: £150 for a single question answered in writing within two working days, £250 for a second opinion, £450 for a review of one system, and £795 for a full review of your business. All prices exclude VAT.

These prices are built for businesses of up to 25 staff. Above that, the price rises with headcount.

Working with your IT team

Do I have to get rid of my existing IT provider?

No. Systems Secure is designed to work alongside your existing IT support, not replace it. Whether your IT is outsourced or in-house, they carry on running your systems, users and everyday technology, and receive clear, specific actions from us whenever their help is needed.

The two roles are different jobs. Your IT team keeps the business running; Systems Secure checks that it's actually protected. You get an independent view of what's protected, what has changed and what should happen next — without disrupting a relationship that's already working.

We have our own IT manager. Do we still need an outside security firm?

Usually yes — and it tends to help them rather than undermine them. An in-house IT manager is responsible for keeping everything running, which means security competes with a hundred other urgent things every week. It also means they would be reporting on the quality of their own work, which isn't a fair position to put anyone in.

Systems Secure gives your IT manager a specialist to escalate to and a second pair of eyes on the things that matter, and gives you a view that doesn't depend on one person's workload or judgement.

What is the difference between IT support and cyber security?

IT support keeps your technology working: fixing problems, setting up new starters, keeping systems online. Cyber security is a separate job — finding weaknesses before an attacker does, strengthening protection, and checking that important controls are still working months after they were switched on.

Good IT teams, in-house or outsourced, do handle parts of security — including updates, backups and access control. What they rarely provide is independent oversight: someone whose only job is to look for the gaps, and who has no reason to report that everything is fine.

My IT company says they already handle security. Do I need you as well?

Possibly not — and Systems Secure will tell you honestly if that's the case. But two things are worth knowing: nobody is well placed to audit their own work, and IT providers are themselves a target for attackers looking for a route into their customers' networks.

In a joint advisory, the UK's National Cyber Security Centre — alongside CISA, the NSA, the FBI and their Australian, Canadian and New Zealand counterparts — warned that managed service providers are granted privileged access to a customer's network, which can create opportunities for attackers.

That isn't hypothetical. In July 2021 attackers exploited a flaw in Kaseya VSA, remote management software used by IT providers, and reached an estimated 800 to 1,500 businesses through around 60 providers. None of those businesses did anything wrong. They were reached through a supplier they trusted.

So the question worth asking isn't "do you handle security?" It's "when did you last check that it's working, and can I see the evidence?"

Risk and threats

Is my business too small to be a cyber target?

No. In the last 12 months, 46% of UK small businesses and 42% of micro businesses identified a cyber security breach or attack, according to the Government's Cyber Security Breaches Survey 2025/26.

Most attacks aren't personally chosen — they're automated. Software scans the internet looking for weaknesses and takes whatever it finds. A business with three staff and a website nobody visits still gets probed daily. Phishing remains by far the most common method, experienced by 38% of businesses.

Isn't antivirus enough?

No. Antivirus catches known threats, but most modern attacks don't rely on a recognisable file. Phishing, stolen passwords and misconfigured settings all bypass antivirus entirely.

Proper protection needs several layers: monitoring that spots unusual behaviour, multi-factor authentication, patching, backups you've actually tested, and staff who can recognise a convincing fake email.

Isn't cyber insurance enough on its own?

No. Most cyber insurance policies require you to prove you took reasonable precautions — multi-factor authentication, staff training, patch management. If you can't demonstrate those, a claim can be reduced or refused entirely.

Insurers increasingly expect standards such as Cyber Essentials before they'll offer cover or renew it. Insurance is worth having, but it pays out after the damage. It doesn't prevent it.

What happens if we get attacked anyway?

No security company can promise you'll never be attacked, and Systems Secure doesn't make that promise. What it does offer is a three-month refund guarantee: if your business is compromised while you're following the agreed security plan, you get three months' fees back.

The realistic goal is fewer incidents, caught earlier and contained faster.

The service

What do I actually get each month?

Every package includes round-the-clock monitoring, automatic updates, protection against viruses and ransomware, blocking of dangerous websites, and staff training. Larger packages add cloud backup, alerts when a login is stolen, regular checks for weak spots, firewall and network reviews, written security policies and a quarterly review.

Micro Business and Business Pro also include a short monthly summary showing what's protected, what changed and what needs attention — written in plain English rather than as a long technical report.

What size businesses do you work with?

From sole traders up to businesses of around 250 staff. There are three packages: Sole Trader for one person, Micro Business for one to nine people, and Business Pro for ten to 250. Business Pro has a minimum of ten accounts.

Do you only work with businesses in West Sussex?

No. Systems Secure is based in Copthorne, West Sussex, and works with businesses across the UK. Almost all of the work is done remotely, so your location doesn't affect the service or the price.

On-site visits are available and charged separately: £240 for a visit of up to two hours, £400 for a half day and £760 for a full day.

Can you help us get Cyber Essentials?

Yes. Cyber Essentials readiness support is included in the Business Pro package. That means reviewing your current setup against the requirements, telling you what needs to change, and getting you to the point where you can pass.

Worth knowing: Cyber Essentials reflects the day of assessment, not a permanent state. Ongoing patching, access reviews and vulnerability checks are what keep the certificate meaningful between renewals.

Who you're dealing with

Who will I actually be dealing with?

James Batt. Systems Secure deliberately caps its managed security client list at 20, so you deal with the same person every time rather than a rotating support desk.

Systems Secure will also never take on a direct competitor of an existing client.

What qualifications does James Batt hold?

James Batt holds CISSP, C|CISO (Certified Chief Information Security Officer), CEH (Certified Ethical Hacker), NCSP Practitioner and CompTIA Security+.

Behind those: 21 years designing multi-million-dollar IT systems for the oil and gas industry, and 16 years running Systems Secure. The company was named Cybersecurity Company of the Year at the West Sussex Business Awards 2025, and Security Solution Specialists of the Year at the E2 Media Awards 2025.

Why do you only take on 20 clients?

Because security oversight is only worth paying for if someone is genuinely paying attention. Capping the list at 20 clients means each one gets real scrutiny rather than an automated dashboard nobody reads.

It also means Systems Secure can be honest about capacity rather than selling a service it can't properly deliver.
