AI has changed how every company works, and how every company gets attacked. Employees use AI tools IT doesn't know about. Attackers craft deepfakes, vishing calls, and spear phishing emails that get past filters. Adaptive addresses all of it in one unified platform: managing AI tool usage before it becomes a liability, training employees on the threats they'll actually face, simulating AI-powered attacks, and protecting the inbox and browser so threats never reach their intended targets. Because it's one platform, Adaptive develops a complete risk picture and uses it automatically, applying targeted training, attack simulations, and policy controls to lower risk over time. More than 1,000 organizations run Adaptive to manage their human security program, having raised $150M+ from NVIDIA, Andreessen Horowitz, Bain Capital Ventures, and Citi Ventures. 91 Ratings Visit Website
About HtmlUnit is a "GUI-Less browser for Java programs" that models HTML documents and provides an API to interact with web pages, such as invoking pages, filling out forms, and clicking links, similar to a standard web browser. It offers fairly good JavaScript support, which is constantly improving and is capable of handling complex AJAX libraries, simulating browsers like Chrome, Firefox, or Edge depending on the configuration used. Typically used for testing purposes or retrieving information from websites, HtmlUnit is not a generic unit testing framework but is intended to simulate a browser within another testing framework such as JUnit or TestNG. It is utilized as the underlying "browser" by various open source tools like WebDriver, Arquillian Drone, and Serenity BDD, and is employed by many projects for automated web testing, including Apache Shiro, Apache Struts, and Quarkus.	About Playwright supports all modern rendering engines including Chromium, WebKit, and Firefox. Test on Windows, Linux, and macOS, locally or on CI, headless or headed. Playwright waits for elements to be actionable prior to performing actions. It also has a rich set of introspection events. The combination of the two eliminates the need for artificial timeouts - the primary cause of flaky tests. Playwright assertions are created specifically for the dynamic web. Checks are automatically retried until the necessary conditions are met. Configure test retry strategy, capture execution trace, videos, screenshots to eliminate flakes. Browsers run web content belonging to different origins in different processes. Playwright is aligned with the modern browsers architecture and runs tests out-of-process. This makes Playwright free of the typical in-process test runner limitations.
