Microsoft 365 powers email, files, and collaboration for millions of businesses. But out of the box, it isn’t fully secure. More than 95 important security settings are left turned off by default — leaving your business vulnerable to phishing, account takeovers, and data leaks.
A Microsoft 365 Security Review from BITSmart Technology ensures your environment is properly configured, hardened, and ready to withstand today’s cyber threats.
Phishing is still the number one way criminals break in.
Stolen passwords can give attackers instant access to your systems.
Misconfigured file sharing can expose sensitive documents.
Unmanaged devices create data protection and compliance risks.
The impact of a breach is far greater than the cost of prevention — lost revenue, downtime, fines, and damaged reputation.
We take Microsoft 365 beyond the default setup and configure it to industry best practice. That means your business is protected against the threats that most commonly affect small and medium-sized organisations.
We benchmark your Microsoft 365 setup against industry best practice across five key areas:
We enforce Multi-Factor Authentication (MFA), apply Conditional Access rules, block outdated login methods, separate admin accounts, and restrict risky guest access. This makes it much harder for hackers to break in — even if passwords are stolen.
We configure SPF, DKIM, and DMARC to stop spoofing. Microsoft Defender tools such as Safe Links and Safe Attachments are applied to block phishing and malware. We also enable mailbox auditing and prevent secret forwarding rules.
We secure sharing so files always require sign-in, disable guest re-sharing, set idle timeouts, and block legacy protocols. This prevents accidental leaks and ensures only the right people can access your data.
We restrict anonymous joins, prevent auto-admit, and give control over who can present or share content in meetings. That keeps your collaboration safe and your information private.
We use Intune compliance policies, encryption (BitLocker or FileVault), and LAPS for local admin accounts. This ensures only secure devices can access company data and reduces the risk from lost or stolen laptops and phones.
We lock down Microsoft 365 so your business is protected from phishing, hacking, and data theft.
We help you meet UK requirements like GDPR and Cyber Essentials without the stress of figuring it out alone.
Security isn’t set-and-forget. We keep an eye on threats and review settings so you stay protected long term.
By closing common security gaps, we reduce the chances of sensitive information falling into the wrong hands.
No disruption — we strengthen Microsoft 365 so it fits neatly with your current IT setup.
We make sure only the right people have access to the right data, reducing insider and accidental risks.
We don’t use a one-size-fits-all approach. Policies are tailored to your people, your systems, and how you work.
Whether in the office or at home, your team can connect safely with protected remote access.

MFA adds a second step to logins, like approving a notification on your phone.
Microsoft says it blocks 99% of account compromise attempts.

Yes. Small businesses are often seen as easier targets. A breach can cost far more in downtime, fines, and lost clients than prevention.
Risks include secret email forwarding, data leaks, uninvited Teams attendees, and compromised devices. These are the gaps we close for you.
Booking your review is simple:
Fill out our booking form – tell us a little about your business and your Microsoft 365 setup.
We perform the audit – our team will securely review your tenant against 95+ best practice controls.
You receive a clear report – highlighting what’s compliant, what’s not, and why it matters.
We arrange a call – to walk you through the results in plain English and answer any questions.
The cost of the review is £99 + VAT.
Once you’ve seen your results, you’ll have two choices for getting non-compliant areas fixed:
One-off Project
We’ll carry out all the necessary hardening work as a standalone project.
Ideal if you want us to bring your system up to standard in one go.
Please note: this doesn’t guarantee ongoing compliance if new risks arise.
If you agree within 48 hours of your review call, we’ll deduct the £99 audit fee from the project cost.
Ongoing Compliance
We’ll not only fix today’s issues but keep your Microsoft 365 compliant going forward.
Available as a standalone service or included in our Managed IT Service bundle.
Billed monthly based on the number of licensed users.
If you sign up within 48 hours of your review call, your £99 audit fee will be credited back, spread across your first 12 months.
Pricing on both of these options will be dependent to your business situation and will be discussed on the call.
