Why Professional Services Firms Are Losing Control of Data – And Don’t Know It

Ask a partner at any professional services firm whether their client data is secure, and the answer will likely be yes. Ask them where all of it is – across shared folders, personal cloud accounts, or a former employee’s inbox – and the confidence fades. For firms across Oxford and the surrounding counties handling sensitive client information, this gap between perception and reality is where data governance falls apart.

The problem starts with everyday tools: email threads, shared drives, personal OneDrive accounts, and third-party platforms adopted by individual teams. Each one creates another place where data settles, unmanaged and unmonitored, until a well-run IT environment becomes a patchwork of ungoverned information.

How Data Sprawl Takes Hold in Oxford’s Professional Services Firms

Professional services firms are particularly vulnerable to data sprawl because of how they work. Projects involve multiple stakeholders, frequent document sharing, and tight deadlines that reward speed over process. A proposal goes out via a third-party platform. A contract is edited and reviewed over email. A client’s financial records sit in a shared drive that was set up years ago by someone who has since left.

According to Gartner research cited by TechRadar, 75% of employees are expected to acquire, modify, or create technology outside of IT’s visibility by 2027, up from 41% in 2022. For Oxford professional services firms where staff routinely work across client sites, home offices, and multiple devices, this trend is already well advanced. Files end up in personal cloud accounts. Teams adopt collaboration tools without checking whether they meet data handling requirements. Shared drives accumulate documents with no clear owner, no retention schedule, and no access controls.

This only happens because people are trying to get their work done, and the tools that make that easiest aren’t always the ones IT has approved. These are the same kinds of hidden cyber security gaps that often go undetected until a formal audit brings them to light.

The Business Risks Hiding in Ungoverned Data

When data governance breaks down, the consequences go beyond IT. For professional services firms, the risks are commercial and reputational.

Confidentiality is the most obvious concern. Client data stored in unmanaged locations – a former employee’s personal OneDrive, a Dropbox folder shared with an external consultant – creates exposure that’s difficult to trace. If a client asks where their data is held and who has accessed it, many firms will struggle to answer with any certainty.

Compliance is the second pressure point. The UK GDPR requires organisations to demonstrate that they know what personal data they hold, where it is stored, and how it is protected. The GRC Solutions GDPR Benchmark Report 2025, which analysed gap-assessment data from more than 60 organisations across eight sectors, found persistent weaknesses in privacy by design, data handling controls, and accountability, even after eight years of enforcement. The Data (Use and Access) Act 2025, which received Royal Assent in June 2025, introduces further obligations around complaint handling, automated decision-making, and documentation, giving the ICO more grounds to intervene where governance is lacking.

A firm doesn’t need to suffer a headline-grabbing breach to lose a client’s trust. A poorly handled subject access request, a compliance audit that reveals gaps, or a prospective client’s due diligence process can expose governance weaknesses that call professional credibility into question. As Kingsley Napley noted, 2026 is shaping up to be the most consequential year for UK data protection enforcement since the introduction of the GDPR regime.

Can You Answer These Three Data Control Questions?

Before reading further, consider whether your firm can confidently answer the following:

1. Who owns each category of data your firm holds? Not which system stores it, but which person or team is accountable for its security and lifecycle.
2. Where does your data live? Beyond your core systems, are files sitting in personal email accounts, third-party platforms, or cloud storage outside your IT team’s visibility?
3. Who can access sensitive client information right now? Not who should be able to. Who already can, including former staff and anyone with a shared link?

If the answers feel uncertain, that uncertainty is itself the risk.

Why Reactive IT Support Doesn’t Solve Data Governance

Most IT support models are built to fix things when they break. A server goes down, a laptop needs replacing, or a user can’t connect to the VPN. These are important services, but they operate at the surface level. Data governance sits underneath, and it rarely gets the same attention.

Reactive IT typically doesn’t include data classification, lifecycle rules for documents, or an accountability structure assigning ownership of information governance to a named individual. A firm’s systems can be well maintained and technically secure while the data flowing through them remains ungoverned. Firewalls protect the perimeter, but no one is managing what happens inside it.

The Okta Businesses at Work Report 2025 found that the average UK firm with fewer than 500 staff relies on 139 SaaS tools, yet barely one in ten track them comprehensively. For professional services firms in Oxford, where the data itself is often the product or the basis of the advice being given, this gap between system security and data governance is a material business risk.

Reframing Data as a Business Asset, Not Just Digital Files

Addressing data governance starts with treating data as a business asset that requires the same oversight as client relationships, financial records, or regulatory compliance.

That means establishing visibility – a clear picture of what data the firm holds, where it sits, who can access it, and what rules apply to its retention. It means creating accountability and building policies that cover how data is used day to day, not just how systems are configured.

Proactive IT support plays a central role. Rather than simply maintaining systems and responding to tickets, a proactive approach includes governance strategy, regular audits of data handling practices, usage controls, and clear reporting that gives senior leadership visibility over information risk.

Understand Where You Stand in Q2

Data governance gaps widen over time as teams grow, tools multiply, and projects accumulate. The firms that address this early protect their client relationships, their compliance posture, and their professional reputation.

A data visibility audit is a practical starting point – a structured review of where your firm’s data lives, who has access, and where governance gaps exist, without disrupting operations.
