Sensitive Data Discovery

Most organisations cannot answer one basic question about their sensitive data. Can you?

Where is your sensitive data? Not where your policies say it should be. Where it actually is. 

In most organisations, sensitive data has spread well beyond the systems it was intended to stay in. PII sits in email attachments. Financial records live in shared drives that nobody owns. HR documents have been forwarded, copied, and re-saved across ten different locations. Legacy archives contain data from systems that were decommissioned years ago. Nobody has a complete picture. 

That incomplete picture is where breaches become expensive. When an incident occurs or an audit lands, the question is not what your policies say. It is what the evidence shows. 

GuardWare DISCOVER gives you the complete picture, fast, without disruption, and without moving a single file.

The challenge 

Sensitive data does not stay where you put it. It moves, copies, and accumulates without oversight. 

Ownership disappears when projects finish and teams move on. Permissions drift silently through inherited groups and one-off exceptions. Classification is inconsistent across the organisation. Unstructured data, documents, spreadsheets, designs, and email attachments carry the bulk of the risk and are the hardest to govern. 

AI tools make this worse. Copilot and other AI assistants follow permissions, not sensitivity. If your data is over-permissioned or unclassified, AI can find it, summarise it, and surface it to users who should not have access. 

How GuardWare solves it 

GuardWare DISCOVER scans files, text, and images across every connected repository using agentless architecture. It identifies PII, PCI, PHI, cardholder data, and business-sensitive content using rule-based classification. It classifies and tags data at the source, applies Microsoft Purview labels where applicable, and produces a ranked exposure report showing your highest-risk repositories and a prioritised remediation plan. 

The entire process takes hours to set up, not months. No data is moved. No infrastructure is disrupted. 

The Outcome 
  • A complete, evidence-based map of sensitive data across M365, file shares, endpoints, and legacy archives 
  • Classification and tagging of PII, PCI, PHI, and business-sensitive content at the source 
  • A ranked exposure report showing highest-risk repositories and where permissions need tightening 
  • A prioritised remediation plan tied to risk and effort 
  • Decentralised remediation alerts to data owners for faster, accountable action 
  • Evidence base for AI rollouts, audit responses, incident triage, and regulatory submissions 
How it works
Locate

Agentless scanning across M365 email, SharePoint, OneDrive, Windows, Linux, cloud platforms, file shares, and legacy archives. Identifies PII, PCI, PHI, and business-sensitive content wherever it sits.

Investigate

Every finding shows ownership, sensitivity level, classification status, creation date, and file attributes. You know what was found, where it lives, and who is accountable.

Remediate

Classify, delete, or move sensitive data. Decentralised alerts go to data owners. Information owners engage directly in remediation. Your security team oversees without doing all the work.

Common Questions

Sensitive data discovery is the process of finding and classifying sensitive information across an organisation's digital environment. This includes personally identifiable information (PII), payment card data (PCI), protected health information (PHI), and business-sensitive content such as contracts, IP, and financial records. The goal is to produce an evidence-based map of where sensitive data exists so it can be protected, governed, and managed.

Data classification is the process of organising data into categories based on its sensitivity and value to the organisation. Classification enables appropriate security controls to be applied to each category. GuardWare DISCOVER applies rule-based classification to identified sensitive data and can apply Microsoft Purview labels to integrate with existing classification frameworks.

GuardWare DISCOVER scans files, text, and images across M365 email, SharePoint, OneDrive, Windows, Linux, cloud platforms, file shares, and legacy archives using agentless architecture. It identifies PII, PCI, PHI, and business-sensitive content using rule-based detection and produces a ranked report of findings.

GuardWare DISCOVER is operational within hours. The Proof of Value scan takes approximately two hours to configure. Scan duration depends on environment size. Results are available as a ranked exposure report and prioritised remediation plan.

No. GuardWare DISCOVER operates independently of Microsoft Purview. It can integrate with Purview to apply existing labels to identified data, but it does not require Purview to function. It works across any Microsoft licence tier.

DSPM stands for Data Security Posture Management. It is the discipline of continuously discovering, classifying, and monitoring sensitive data to understand exposure and enforce appropriate controlsGuardWare DISCOVER and INSIGHT together deliver full DSPM capability, with GuardWare PROTECT adding persistent encryption to create the DSPM + PE category.
