At SiteGround, we don't offer free trial accounts, but we do provide a 30-day money-back guarantee for all shared accounts. This allows you to try our services risk-free and decide if they are right for you. On all plans, even the cheapest, SiteGround offers a free daily backup. This should make data loss much less likely, but it's still a good idea to make your own backups using the various tools available.
SiteGround also offers a managed WordPress service on all its plans. This includes automatic updates to the main and free plugins, as well as practical tools such as staging, WP-CLI, WordPress Starter and WordPress Migrator. Performance and security features are also available at the server and application level through the SiteGround Optimizer plugin and security plugin from SiteGround.
