On your pricing plans page [0], there's a misleading statement that Cloudflare's free tier doesn't provide DDoS protection, but Cloudflare's pricing and feature page [1] states that the free tier does come with basic DDoS protection. Whether or not there's a difference in the type of DDoS protection provided by Kloudsec, this feels deceptive.
For what it matters, CloudFlare protected my site against a 200mbps layer 4 attack on the fre plan. That's a small attack but it's great for a free basic offering.
And yesterday we (CloudFlare) protected a free customer against a 400Gbps (that's not a typo) Layer 3/4 attack. DDoS protection should be free at any volume and our scale is allowing us to make that a reality.
Looks good! Just beware that you don't give away too much for free though. A free plan is a good idea, but you've got to be fiscally sustainable and people are less trusting of services' longevity now because of the recent sustained wave of shutdowns.
