TL;DR: Sensitive data becomes harder to defend when visibility into location, access and usage is incomplete, according to ArexData. Data security then shifts from broad cleanup to precise containment, because response depends on knowing exactly what was exposed and by whom.
Editorial analysis by NHI Mgmt Group, based on content published by ArexData: “How to mitigate a data leak with DSPM”.
Key questions
Q: Why do excessive permissions make exposure management less reliable?
A: Excessive permissions widen blast radius because they turn small misconfigurations into usable attacker paths.
Q: How can behavioural analytics help protect sensitive data?
A: Behavioural analytics helps protect sensitive data by spotting access patterns that differ from normal use, such as mass downloads, unusual query times, atypical geographies or sudden sharing.
Q: How do teams reduce data leak risk with data discovery?
A: Data discovery reduces leak risk by scanning cloud stores, file shares, databases and endpoints to find sensitive data, classify it and map where it moves.
Practitioner guidance
- Map sensitive data exposure paths Inventory where regulated, confidential and operationally critical data resides, then document which users, services and processes can reach each location.
- Tighten entitlement scope for data stores Review database, file and object-store permissions for unnecessary write, export and administrative access, then remove standing overreach.
- Baseline normal data usage patterns Establish behavioural baselines for people, automated jobs and AI agents so deviations in access timing, volume or destination can be triaged quickly.
Bottom line: Data leaks become harder to contain when organisations cannot see where sensitive information resides or who can touch it.

Data visibility debt is now a governance liability: organisations that cannot see where sensitive data lives or who touches it are running an uncontrolled exposure model. Discovery, classification and access mapping are not administrative hygiene; they define the blast radius available to an attacker or a careless insider. The practical conclusion is that data governance must be measurable before it can be enforceable.
A few things that frame the scale:
- Only 5.7% of organisations have full visibility into their service accounts, according to the Ultimate Guide to NHIs.
A question worth separating out:
Q: What should security and compliance teams do after a major data leak is discovered?
A: Security and compliance teams should first contain access, preserve evidence, and map what data was exposed. Then they should review permissions, rotate any affected credentials, and notify legal, privacy, and executive stakeholders through an agreed incident process. The longer the organisation waits, the harder it becomes to prove scope, assess impact, and satisfy regulatory obligations.
