For collaboration with recurring contacts without a compatible file cloud for federation, the Guest User<\/a> feature is a suitable option. Guests can access files and folders shared with them, even using the desktop client and the ownCloud app, like „real“ users, just without their own storage quota.<\/p>\n For working with sporadic contacts, it’s helpful to create a Drop Folder<\/a> – a password-protected folder to which a person or group outside the organization can upload, but whose contents they cannot see or list. Of course, rules and policies also apply to such folders, and of course those uploads too are checked by the File Firewall<\/a> and the Antivirus Scanner<\/a>.<\/p>\n ownCloud also offers a highly protected data room. With Secure View<\/a>, documents requiring protection can be shared with a selected audience for viewing only, with watermarks and usage restrictions for maximum control.<\/p>\n ownCloud enables safe collaboration across business ecosystems<\/p><\/div>\n Across all features, expiry dates prevent compliance debacles arising from ‚forgotten‘ shares. ownCloud’s File Lifecycle Management<\/a> helps to keep documents only as long as they are needed. The Activity Stream<\/a> and Auditing<\/a> apps help organizations keep track of documents access. The Classification<\/a> app automates policies towards documents.<\/p>\n With ownCloud, companies get a comprehensive and secure solution for collaboration, whether internally or with other companies. Its architecture and feature set also make ownCloud a sensible addition to public cloud services already used in the company that are not by themselves suitable for sensitive data. <\/p>\n![\"How](\"https:\/\/owncloud.com\/wp-content\/uploads\/2020\/09\/owncloud-collaboration-1024x576.png\")
