FourCore ATTACK is a commercial breach & attack simulation solution by FourCore. Qualys TotalAppSec is a commercial dynamic application security testing solution by Qualys. Features, integrations, deployment and the company behind each one, side by side.
What our shortlists say about the one we picked.
Best for: Enterprises consolidating DAST with Qualys VM and cloud asset inventory
The limitation is that TotalAppSec delivers the most value when you are already in the Qualys ecosystem, specifically running Qualys CSAM or VMDR. The integrations with those products are native and tight. As a standalone DAST solution evaluated in isolation, the complexity of the platform may outweigh the benefits for teams without existing Qualys investment. This is an enterprise play, and it is priced and scoped accordingly.
