▸Company Profile

Ruby is an open-source programming language developed in Japan, known for its simplicity and productivity. The Ruby language itself is maintained by a community of developers, not a single vendor, and is widely used for web development, particularly with the Ruby on Rails framework. Its cybersecurity relevance stems from vulnerabilities in the language's interpreter and standard libraries, which are tracked via CVEs.
