ROT stands for redundant, obsolete, and trivial data: duplicate files, outdated records, and content that no longer serves a business purpose. It piles up across file shares, Microsoft 365, and cloud storage, where it drives up storage costs, widens the attack surface, and makes compliance harder. Netwrix Data Classification finds this data, flags what holds sensitive information, and helps you clean it up.

Storage tiering and lifecycle policies mostly act on age or location and treat every file the same. Netwrix is sensitivity-aware and works across file systems, Microsoft 365, cloud, and databases rather than a single repository, so cleanup decisions reflect what the data actually contains and the risk it carries.

Every file you keep is something you have to secure, monitor, and account for during an audit. Removing redundant, obsolete, and trivial data shrinks the sensitive information exposed if an account is compromised, lowers storage and eDiscovery costs, and makes it easier to prove you only hold data you still need.

It often holds sensitive information (PII, PHI, PCI, IP) that no longer serves a business purpose but still shows up in permission audits and still leaks in breaches.

Through content analysis, metadata inspection, and activity signals that surface duplicates, stale files, orphaned content, and low-value trivia, with sensitivity classification alongside so cleanup respects retention rules.

Yes, with sensitivity-aware policies. Low-risk categories are handled automatically, while sensitive ROT routes to human review before deletion.

Depending on the environment, ROT cleanup typically frees 20 to 50 percent of file storage in the first year.

Classification identifies what a file contains and how sensitive it is, which is a prerequisite for confidently deciding whether it is redundant, obsolete, or trivial. Without classification, ROT data is hard to tell apart from files that look unused but are still business-critical or regulated.

Dark data is the broader category: any data an organization stores but has no visibility into or active use for. ROT data is a subset of dark data made up specifically of redundant, obsolete, and trivial files. All ROT data is dark data, but not all dark data is ROT, some of it may still hold business or compliance value once it is properly classified.
