I have researched the possibility for securing / inspecting FTPs traffic with a sandbox to do malware filtering.
There are a lot of vendors offering WAFs (Fortinet, Cloudflare, Check Point, and so on) for HTTPs-Services, but I could not find any vendor, that offers the inspection of FTPs services.
Is there any advice how to secure a internal FTPs-Server beside Layer-4 filtering from a firewall perimeter firewall?
Thanks and best regards
