Think about the data your business handles on any given day. It could be customer contact details, financial records, employee information, contracts, or payment data – there’s probably more than you realise. Most businesses accumulate a significant amount of sensitive information without ever stopping to consider what would happen if it ended up in the wrong hands or what their legal obligations are around protecting it.
Data protection has traditionally been framed as an enterprise concern. But regulators don’t see it that way, and neither do cybercriminals. GDPR applies to any business that handles the personal data of UK or EU residents, regardless of size. 2025 saw a sustained high level of data enforcement activity, with European supervisory authorities issuing fines that totalled approximately £1.06 billion.
Strong data protection doesn’t require an enterprise budget or a team of specialists. It just takes the right practices, the right tools, and an IT support partner who can help you put both in place.
Do You Know the True Value of Your Data?
It’s not uncommon for businesses to underestimate how much sensitive information they’re holding (and how much it’s worth to someone else.)
Customer records, payment details, employee files, supplier contracts – individually, these might feel unremarkable. Together, they form exactly the kind of data that attackers target and that regulators expect to be properly protected. According to IBM’s Cost of a Data Breach 2025 Report, the average breach now costs $4.88 million globally and takes 204 days to identify. For a small business, that timeline alone can be enough to cause irreversible damage.
The consequences don’t stop at recovery costs either. A breach is almost always a compliance failure too, and regulators treat it that way. Businesses that suffer a breach while found to be non-compliant face significantly higher financial exposure, and one in three organisations paid regulatory fines following a breach in 2025. Beyond the financial impact, the reputational damage of losing customer data is harder to quantify and often harder to recover from. The data most small businesses handle every day carries real responsibility, and that responsibility is worth taking seriously before something goes wrong, not after.
Data Protection Best Practices
For most small and medium enterprises (SMEs), effective data protection comes down to four fundamentals. Getting these right puts you in a significantly stronger position than the majority of businesses your size.
Know what data you hold: You can’t protect what you haven’t mapped. Before anything else, it’s worth understanding what sensitive information your business holds, where it lives, and who has access to it. For many businesses, this exercise alone surfaces data that’s being stored unnecessarily or in places it shouldn’t be.
Control who can access it: Most data breaches don’t require sophisticated hacking. They exploit unnecessarily broad access permissions where too many people have access to too much. Limiting sensitive information to those who genuinely need it, and reviewing that access regularly, is one of the most straightforward ways to reduce your exposure.
Encrypt sensitive data: Encryption ensures that even if data is accessed without authorisation, it can’t be read or used. This applies to both data in storage and data in transit – emails, file transfers, cloud storage. It’s increasingly a baseline expectation from both regulators and cyber insurers, rather than an advanced measure reserved for large organisations.
Train your team: 83% of SMEs in a Microsoft survey identified a lack of employee security awareness and training for phishing attacks as a key security struggle. A well-intentioned employee clicking the wrong link or forwarding a file to the wrong recipient remains one of the most common ways sensitive data ends up in the wrong hands, with 95% of cyber security incidents attributed to human error. Regular, straightforward training, rather than a one-off exercise, makes a meaningful difference.
The Tools That Make It Manageable
Knowing what best practice looks like is one thing, but having the tools to put it into practice consistently is another. This is where a lot of small businesses hit a wall, because the tools that make data protection manageable have traditionally been expensive, complex, and built with enterprise IT teams in mind.
However, that has shifted in recent years. If your business is already running Microsoft 365, you may have access to Microsoft Purview – a suite of data security and compliance capabilities built directly into the platform your team is already using.
Where the Microsoft 365 Defender Suite focuses on protecting your business from external threats, Purview is focused on protecting the data itself: what it is, where it goes, who can access it, and whether your business is meeting its compliance obligations.
Data Loss Prevention keeps sensitive information from leaving your business in ways it shouldn’t, whether that’s an employee accidentally emailing a customer database externally or a more deliberate attempt to extract data.
Sensitivity labels allow you to classify documents and emails based on how sensitive they are and automatically apply the right protections. A file marked as confidential can be restricted, encrypted, and tracked without anyone having to manually manage it.
Insider risk management flags unusual behaviour within your organisation, such as large volumes of data being downloaded or files being shared externally at unusual times, before it becomes a problem. Not every data incident comes from outside the business.
Compliance monitoring gives you a clear, ongoing view of whether your business is meeting its regulatory obligations, with tools that help you demonstrate that to auditors, clients, or insurers when it matters.
Together, these capabilities close the gap between having a data protection policy and being able to show that it’s working.
How Integy Helps You Take Control of Your Data Security
Data protection is one of those areas where businesses often have more in place than they’re making use of – and more gaps than they realise. As a Microsoft partner, helping businesses understand and close that gap is a significant part of what we do.
When we work with an SME on their data protection setup, here’s what that typically looks like:
- Starting with what you’ve actually got — before recommending anything, we look at how your data is currently being stored, accessed, and protected and how that maps against your compliance obligations. For most businesses, that conversation surfaces a few things worth addressing straight away.
- Configuring Purview around how you actually work — getting the most out of Microsoft Purview means setting it up to reflect your business, the types of data you handle, the regulations relevant to your sector, and the way your team operates day to day.
- Helping you demonstrate compliance, not just achieve it — whether you’re working towards Cyber Essentials, responding to a client’s due diligence questionnaire, or preparing for an audit, we make sure the evidence is there when you need it.
- Keeping things clear — If you have an internal IT person or team, we work alongside them and we’re straightforward about what we’re doing and why.
Data Protection Is an Ongoing Responsibility
Data protection isn’t a project you complete and move on from. Regulations evolve, your business changes, and the ways sensitive information is created, shared, and stored shift constantly. The businesses that stay on the right side of compliance are the ones that treat it as an ongoing discipline rather than another box to tick.
The practical steps are well within reach for most SMEs, and the tools to support them are likely already part of your Microsoft subscription. The missing piece, more often than not, is having the right support in place to configure everything properly and keep it that way.
