The large community is one of the most important and compelling aspects of Drupal. Drupal and its community have been maturing for 15 years. More than 3,000 people contributed to Drupal through code contributions, testing, and more. That same community stands with hundreds of thousands of Drupal developers who not only build their digital experience projects on Drupal, but who continually support, update, troubleshoot, and further enhance the Drupal platform.
As there is a very large community working behind Drupal it is one of the most secure content management systems. The security features include:
Drupal has built-in performance features like caching which can be combined along with a modern CDN provider for performing well under high loads. Lot of high traffic sites run in Drupal platform.
Drupal core has modules that allows translating every part of the site. Drupal 8 allows detection of user language based on the IP address, browser settings etc which is configurable. Drupal 8 supports languages with right-to-left text direction.
Drupal 8 is architected to be fully responsive out-of-the-box. You can use the platform to deliver experiences on a web browser, on a phone, on a tablet, or anywhere else content and data need to flow today and in the future.
