IntelliSense encompasses a variety of code editing functionalities, such as code completion, parameter information, quick insights, and member lists. These features may also be referred to by different names including "code completion," "content assist," and "code hinting." In Visual Studio Code, IntelliSense is readily available for languages like JavaScript, TypeScript, JSON, HTML, CSS, SCSS, and Less. Although VS Code inherently supports word-based completions for any programming language, users can enhance their IntelliSense experience by adding specific language extensions. The IntelliSense capabilities in VS Code are driven by a language service, which delivers smart code completions based on the semantics of the language and a thorough examination of your source code. When a language service identifies potential completions, IntelliSense suggestions appear dynamically as you type. As you continue to input characters, the suggestions for members—such as variables and methods—are filtered to show only those that match your input. This makes coding more efficient and intuitive, allowing developers to focus on logic rather than syntax.

DryRun Security has been created based on our extensive experience in training over 10,000 developers and security experts in the realm of application security testing, as well as our work on security products at GitHub and Signal Sciences. Through this experience, we identified a significant gap in the current market: the lack of security context tailored for developers. Since developers are constantly making code adjustments throughout their workdays, they require a security solution that offers relevant security insights, enabling them to work more efficiently and safely. Traditional security code reviews can hinder the progress of development teams, often occurring too late in the production cycle. It is essential for developers to receive security context as soon as a pull request is initiated, allowing them to understand the potential impacts of the code changes being submitted. Up until now, the majority of security testing has employed a one-size-fits-all strategy, leading to developer frustration due to excessive, repetitive alerts and unreliable outcomes. By focusing on providing actionable security context at critical moments, DryRun Security aims to revolutionize the way developers approach security in their workflows.
