According to wikipedia link, MariaDB does not have Security Evaluation Assurance Level (EAL)
Looking at the link below, MariaDB shows "No" for Security Certification. This is based on no Security Evaluation Assurance Level (EAL). https://en.wikipedia.org/wiki/Comparison_of_relational_database_management_systems Does anyone have any information on whether this can be a problem?
Answer Answered by Ian Gilfillan in this comment.
Obtaining EAL certification involves spending hundreds of thousands of dollars (even millions for the top levels) to have the software externally evaluated. It makes no practical difference, except that certain customers (such as, I believe, some US government entities) may insist on it.
