I've been using a CDN for my personal web apps for a few months now. While the performance boost is undeniable, I keep hearing arguments that third-party edge services can become a single point of failure or expose my users to additional privacy concerns. On the other hand, they also provide DDoS mitigation and TLS termination that would be hard to implement on my own. I'm curious how others balance these trade-offs, especially when working on small-scale projects with limited budgets. Do you think the security benefits outweigh the potential risks, or would you rather handle everything in-house? Looking forward to your thoughts.
Is relying on CDN services like Cloudflare a security risk for small projects?

I find that using CDN services like Cloudflare is a very practical option even for small projects. In my recent experience with a personal web app, the TLS termination layer provided by Cloudflare simplified certificate management, and its basic DDoS protection saved the site from random attacks that would have cost me additional local resources to deploy. As for the risks of relying on a third party, these can be minimized by enabling "Always Online" settings, backing up files on the original server, and monitoring service status via Cloudflare's API while being prepared to temporarily switch to the original IP if an outage occurs.
Overall, the security and performance benefits outweigh the potential risks, especially if log inspection policies and firewall rule reviews are regularly enforced. Therefore, I recommend keeping a backup of the content and enabling policies to reduce reliance on a single point of failure, but there’s no major issue with relying on a CDN to reduce the load and provide basic protection on a tight budget.
