I am looking for an alternative to Sqreen (https://www.sqreen.com) which was bought by Datadog and then sunset.<p>Sqreen was an application security platform. Pretty much what an Application Performance Management tool (like New Relic) is doing, but for security. (was featured a few years back on HN: https://news.ycombinator.com/item?id=20215483). The engine houses the Runtime Application Self-Protection (RASP), Content Security Policy (CSP) and Security Headers, and In-App Web Application Firewall (In-App WAF) layers that observe activity and block attacks from within your app.<p>I am now looking for a product with similar features now that Sqreen no longer allows signups.
