Under UK GDPR, any individual can request access to the personal data an organisation holds about them. Simple in theory. In practice, for most businesses I speak to, it triggers a quiet but genuine panic and for good reason.
The challenge isn’t usually intent. Organisations want to comply. The challenge is capability. How confident can you genuinely be that you’ve located every piece of data about that individual, across every system, every department, every corner of your infrastructure, including the parts of it you don’t officially know about?
Shadow IT: the hidden threat to your DSAR compliance
Shadow IT – the applications, cloud services, and tools deployed outside of central IT governance- is now endemic in UK enterprises. Staff use personal Dropbox accounts. Teams spin up their own SaaS tools. Project data lives in spreadsheets emailed between individuals. None of it is formally sanctioned, and almost none of it is mapped.
Why unsanctioned data stores make discovery difficult
For a SARs response, this can be a significant problem. If data lives somewhere your team doesn’t know to look, it won’t be included in the response. That’s not just an operational oversight; it’s a compliance failure. The ICO doesn’t accept “we didn’t know” as a defence.
The risks of relying on manual DSAR workflows for DSAR compliance
Many organisations still manage DSARs by emailing department heads, searching shared drives, checking the CRM, and relying on people to remember where older data lives.
This approach is slow, inconsistent, and unreliable.
Incomplete discovery
Manual searches depend on people knowing which systems to check. Archived databases, older platforms, and unsanctioned tools are often missed. Each gap creates compliance risk.
Oversharing and third-party data exposure
Another common error is including data about other people in the response. Manual redaction is error-prone, especially when teams are under time pressure.
Missed deadlines and ICO exposure
Manual coordination across teams takes time. Staff absence or workload pressure does not pause the 30-day deadline. Late responses attract regulatory attention.

How automated DSAR solutions improve DSAR compliance
A dedicated DSAR solution turns a manual, email-driven task into a repeatable process.
Automated data discovery
Automated discovery scans connected systems such as cloud platforms, CRM, HR software, and document stores to find data linked to the individual without relying on memory.
Intelligent data masking and redaction
Built-in masking removes third-party personal data before disclosure, reducing the risk of accidental breach.
Audit trails and demonstrable compliance
Every step is logged. If challenged, you can show what was searched, what was found, and what was shared.
The business case for a DSAR solution
No manual DSAR process can guarantee completeness, particularly in organisations where shadow IT is common.
You can spend significant staff time and still produce a response that is partial, inconsistent, or non-compliant.
A DSAR solution with automated discovery, masking, and audit records gives you a defensible way to show that you met your legal obligation. As more people use their data rights and regulatory scrutiny increases, relying on a manual process becomes harder to justify.
If you are unsure whether your organisation can locate all personal data within the one-month deadline, it may be time to review your approach. Northdoor provides dedicated DSAR solutions designed for complex data environments and organisations with shadow IT exposure.
