Dear Oleksandr, thank you very much for your review and opinion.
Nowadays the solution 1C:ERP international version has an English interface.
Some of the solutions that were developed based on this product have other languages such as Spanish, Chinese, Vietnamese, Mongolian etc.
In terms of security and transmitted information, 1C products themselves do not send user information, this depends on the features of the customization of solutions and changes that users make independently.
1C:Enterprise platform also has a wide range of integration options with various services popular around the world, for example, Jira, Trello, GitHub, PayPal, etc.
In any case, we are actively developing our international presence and are trying to add more opportunities to our products.
