Azure DDoS Protection cost: a flat monthly plan plus overage

Quick answer

Azure DDoS Protection comes in two tiers: Network Protection bills a flat monthly plan fee (around $3,000/month) covering up to a set number of public IPs with per-IP overage beyond that, and IP Protection bills per protected public IP per month for smaller deployments. The flat plan is cost-effective when you protect many resources; IP Protection suits a few. Choosing the right tier for your resource count is the lever.

Azure DDoS Protection defends public endpoints against volumetric and protocol distributed-denial-of-service attacks, beyond the basic platform protection. It has two tiers with different cost shapes, a flat plan and a per-IP model, so the right choice depends on how many resources you protect.

Two tiers

Tier	Billing
Network Protection	Flat monthly plan (~$3,000) covering a set number of IPs, overage per IP
IP Protection	Per protected public IP per month

Network Protection is a flat monthly plan (around $3,000) that covers up to a set number of public IP resources, with a per-IP charge beyond the included count, so its per-resource cost falls as you protect more. IP Protection bills per protected public IP with no large flat fee, cost-effective for a handful of resources. So many protected resources favor the flat plan; a few favor per-IP.

Which tier

The break-even is the number of resources: below a threshold, per-IP (IP Protection) is cheaper than the flat plan; above it, the flat Network Protection plan's included capacity makes it cheaper per resource. Both include DDoS mitigation, monitoring, and often cost protection (credits for scale-out caused by an attack). So size the choice to your protected-resource count.

Controlling DDoS Protection cost

Choose the tier matching your resource count (IP Protection for a few endpoints, Network Protection when you protect many), protect the public endpoints that need it rather than every IP, and use the cost protection that plans include to guard against attack-driven scale-out bills. The decision is mostly tier selection, since within a tier the pricing is fixed; align it to how many public endpoints you are defending.

FAQ

How is Azure DDoS Protection priced?

In two tiers: Network Protection bills a flat monthly plan fee (around $3,000) covering up to a set number of public IPs with per-IP overage beyond that, and IP Protection bills per protected public IP per month. The flat plan is cost-effective for many resources; IP Protection suits a few.

Which Azure DDoS Protection tier is cheaper?

It depends on how many resources you protect. Below a break-even count, IP Protection's per-IP pricing is cheaper than the flat plan; above it, Network Protection's flat plan and included capacity make it cheaper per resource. So size the choice to your protected-endpoint count.

How do I reduce Azure DDoS Protection cost?

Choose the tier matching your resource count (IP Protection for a few endpoints, Network Protection when you protect many), protect only the public endpoints that need it rather than every IP, and use the cost protection that plans include to guard against attack-driven scale-out bills. Tier selection is the main decision.

What is the difference between Network and IP Protection?

Network Protection is a flat monthly plan (around $3,000) covering a set number of public IPs with per-IP overage, suited to protecting many resources. IP Protection bills per protected public IP with no large flat fee, suited to a handful of endpoints. Both provide DDoS mitigation and monitoring; they differ in cost shape.

Does Azure DDoS Protection include cost protection?

Plans often include DDoS cost protection, credits for the resource scale-out that an attack causes, so a volumetric attack driving autoscaling does not leave you with a large bill. This is part of the value of a paid DDoS plan over relying on basic platform protection alone.

Does C3X estimate DDoS Protection cost?

C3X prices the DDoS Protection plan from your Terraform, including the flat Network Protection fee or per-IP IP Protection charges, so the protection cost appears before deploy. The right tier depends on your protected-resource count, which the resource configuration reflects.
