Hey I'm an engineer who worked at Sqreen and now Datadog. What kind of feature is still missing in Datadog ASM? To my knowledge everything is there except managing CSP and security headers now.
Few months ago when I’ve tried it there was no full support for ruby language.
Ah yes, we are still missing RASP support on ruby, but this should come out in the next 3-6 months. Everything else should be supported though (In App WAF, playbook, user monitoring etc)
