Back to case studies
The problem
A government organisation found confidential internal documents circulating across mirror sites and search results.
Scope
Mirror sites, cloud platforms, forums, search engines and ongoing detection for re-publication.
Actions taken
- Ran a broad exposure scan to locate copies across the open web and higher-risk communities.
- Coordinated takedown requests with hosts, platforms and search engines.
- Built monitoring to identify new appearances quickly.
The outcome
The leaked material was removed or de-indexed from major discovery paths, with monitoring retained for reappearance.
- More than 12,000 URLs containing leaked material were removed in the historical matter.
- Major search engines delisted identified content.
- Ongoing monitoring reduced the risk of new copies staying visible.
