Heimdall is a security scanner designed specifically for the Chrome browser. Developed by Ryan Howell, this free software system aims to improve the analysis and communication of website domain security.

One of the key features of Heimdall is its ability to expand the factors used for security analysis, thus enhancing existing browser security indicators. By doing so, it provides users with a more comprehensive understanding of the security level of a website. This is communicated through a browser extension icon, which utilizes a simple color-coded A - F scoring system.

With Heimdall, users can easily assess the security of websites they visit, allowing them to make informed decisions about their online activities. This browser add-on is a valuable tool for those who prioritize their online security and want to ensure a safe browsing experience.

Overall, Heimdall is a useful security scanner for Chrome users, providing enhanced security analysis and clear communication of website domain security. Its simplicity and effectiveness make it a valuable addition to any security-conscious individual's browser.
