RIAs present indexing challenges to [[Web search engine]]s, but [[Adobe Flash]] content is now at least partially indexable.<ref>{{cite web|url=https://techcrunch.com/2008/06/30/once-nearly-invisible-to-search-engines-flash-files-can-now-be-found-and-indexed/|title=Once Nearly Invisible To Search Engines, Flash Files Can Now Be Found And Indexed|author=Erick Schonfeld|publisher=AOL|work=TechCrunch|date=July 2008 |access-date=2 May 2015}}</ref>

Security can improve over that of [[application software]] (for example through use of [[sandbox (computer security)|sandbox]]es and automatic updates), but the extensions themselves remain subject to [[vulnerability (computing)|vulnerabilities]] and access is often much greater than that of native [[Web application]]s. For security purposes, most RIAs run their client portions within a special isolated area of the client desktop called a sandbox. The sandbox limits visibility and access to the file-system and to the operating system on the client to the application server on the other side of the connection. This approach allows the client system to handle local activities, reformatting and so forth, thereby lowering the amount and frequency of client-server traffic, especially versus client-server implementations built around so-called thin clients.<ref>[http://www.isecpartners.com/files/RIA_World_BH_2008.pdf Living in the RIA World: Blurring the Line Between Web and Desktop Security, 2008]</ref>
