This site allows you to subscribe various vendors and products to receive CVE (Common Vulnerabilities and Exposures) alerts on new releases and changes to existing ones. The emails contain just your selections, so you do not need to scroll through multiple products or vendors that are not of interest. This allows more targeted alerts to products that you use in your environment. I really like this compared to other subscription services as looking through a list of various products/vendors that might be applicable was always a waste of time and had the risk of missing important CVEs.
Improvements: This website is new in the last 6 months and quite basic for the time being. I would like to see an option to specify the level of alerts based on the rating (low, medium or high). Right now, the website will alert you to all new CVEs for the specified products/vendors and any changes regardless of level. Luckily, you just need to go to the site and can filter based on the rating.
