Phish Alert is a free open-source Chrome extension developed by Ben Balcombe. Designed to provide users with an extra layer of assurance when browsing their emails, this cyber security awareness and monitoring tool is a valuable addition to any Gmail user's arsenal.

One of the key features of Phish Alert is its ability to scan emails for common phishing tactics used by cyber criminals. Once an email is opened, the extension silently and unobtrusively performs a number of checks to detect potential phishing emails. The results of this scan are then presented to the user in a friendly and easy-to-understand manner.

It is important to note that Phish Alert does not save or send any email or personal data about the user. This ensures the privacy and security of the user's information. Additionally, the extension offers customizable options, allowing users to choose whether they want to be actively warned when an email is deemed suspicious, as well as adjust the frequency and threshold of these warnings.

In addition to its monitoring capabilities, Phish Alert also serves as an educational tool. It helps users learn what to look for in phishing emails, further enhancing their ability to identify and avoid potential threats.

Overall, Phish Alert is a valuable Chrome extension that provides users with an extra layer of assurance when it comes to cyber security. Its ability to detect and warn against potential phishing emails, coupled with its educational features, make it a must-have tool for Gmail users looking to protect themselves from online threats.
