What's the best way to help prevent Dos attacks to the FTD itself. Is flex config the only way and does anyone have a proven config. for that they could share?</P><P>2. What upstream service could you suggest if the ISP doesn't offer one?</P><P>Thanks</P> Thu, 23 Oct 2025 12:58:59 GMT https://community.cisco.com/t5/network-security/dos-to-ftd/m-p/5341482#M1123262 dcanady55 2025-10-23T12:58:59Z https://community.cisco.com/t5/network-security/dos-to-ftd/m-p/5341491#M1123263 <OL> <LI>Use some upstream cloud-based provider (Cloudflare, Imperva, etc.). Modern DDoS attacks will crush most on-prem things which cannot automatically scale to stop it. Or you need to get your ISP involved.
