At $199.99/year for the Basic plan, Sucuri looks affordable until you reverse-engineer the effective cost per terabyte. The platform bundles CDN delivery with WAF, malware scanning, and DDoS mitigation into opaque annual tiers, which means your actual bandwidth unit cost depends entirely on how much traffic you push through it. For a site doing 500 GB/month, Sucuri's effective CDN cost lands somewhere around $33 per TB. Push 5 TB/month and that number drops below $4 per TB — but you've also hit bandwidth limits that Sucuri doesn't publicly document with hard numbers. This article tears apart Sucuri CDN pricing as of Q2 2026, maps each plan to a cost-per-TB model, compares it against Cloudflare and usage-based alternatives, and gives you a workload-profile decision matrix so you can pick the right tool without overpaying.
Sucuri sells website security platforms, not raw CDN capacity. CDN delivery is included in every plan, but the plans themselves are differentiated by security features, scan frequency, and SLA response times. As of May 2026, the published pricing is:
| Plan | Annual Price | Key Inclusions | Scan Frequency |
|---|---|---|---|
| Basic Platform | $199.99/yr | CDN, WAF, malware scanning, DDoS mitigation | Every 12 hours |
| Pro Platform | $299.99/yr | Everything in Basic + advanced SSL, faster response SLA | Every 6 hours |
| Business Platform | $499.99/yr | Everything in Pro + fastest SLA, continuous scanning | Every 30 minutes |
| Junior (Multi-Site) | Custom / ~$999.99/yr | Multi-site management, bulk malware cleanup | Custom |
Every tier covers a single site. If you run 10 properties, you pay 10× the plan price. Sucuri also offers a standalone Firewall product starting at $9.99/month ($119.88/year) that includes CDN delivery without malware removal services. For teams that only need the WAF + CDN layer, this is the relevant line item.
Sucuri does not publish bandwidth caps or overage fees for any plan. Their documentation states that "fair use" policies apply and that sites with extremely high bandwidth may be asked to upgrade or contacted directly. This is fine for a 50,000-visit/month WordPress site. It's a planning risk for anything running above 1 TB/month.
Here's what the effective cost per TB looks like at different traffic levels on the Basic Platform ($199.99/year):
| Monthly Bandwidth | Annual Bandwidth | Effective Cost/TB |
|---|---|---|
| 200 GB | 2.4 TB | ~$83/TB |
| 500 GB | 6 TB | ~$33/TB |
| 2 TB | 24 TB | ~$8.33/TB |
| 5 TB | 60 TB | ~$3.33/TB |
That last row looks competitive. The problem is you have no contractual guarantee Sucuri will continue serving 5 TB/month on a $199.99/year plan without intervention. For capacity planning purposes, this is an unbounded variable — and that's a category of risk most infrastructure teams don't accept.
Cloudflare's free tier remains unmetered for bandwidth in 2026, which makes it the default comparison. But the free tier ships no WAF rules customization, no bot management, and limited analytics. The Pro plan at $20/month ($240/year) adds the managed WAF ruleset and basic bot mitigation. Business at $200/month adds advanced WAF, SLA commitments, and image optimization.
The comparison that matters: Sucuri Basic ($199.99/year) vs Cloudflare Pro ($240/year). Both include WAF and CDN. Cloudflare Pro gives you unmetered bandwidth with HTTP/2 push, Brotli compression, and Argo smart routing available as a paid add-on. Sucuri gives you malware cleanup and incident response, which Cloudflare doesn't offer at any price tier. If you're a WordPress agency with clients who get hacked, Sucuri's remediation service alone justifies the cost. If you're running a high-traffic SaaS platform and bandwidth predictability matters, Cloudflare's unmetered model wins.
This is where the bundled model breaks down. If you're pushing 50 TB/month across a media property or software distribution pipeline, Sucuri is not your CDN. It was never designed for that workload. The platform is optimized for CMS-driven sites — WordPress, Joomla, Magento — where security scanning and malware cleanup are high-value features and monthly bandwidth sits comfortably under 2 TB.
For high-bandwidth workloads in 2026, usage-based CDNs scale more predictably. BlazingCDN delivers CDN capacity starting at $4/TB for volumes up to 25 TB/month, scaling down to $2/TB at the 2 PB tier. That pricing includes 100% uptime SLA and fast scaling under demand spikes — comparable fault tolerance to Amazon CloudFront, but at a fraction of the cost. For enterprises already spending $10,000+/month on CloudFront or similar, the savings compound fast. BlazingCDN counts Sony among its clients, which speaks to the scale the infrastructure handles.
No single CDN wins every workload. Here's a practical mapping based on 2026 pricing and capabilities:
| Workload Profile | Monthly Bandwidth | Best Fit (2026) | Why |
|---|---|---|---|
| Single WordPress / CMS site, security-first | < 1 TB | Sucuri Basic | Malware cleanup + CDN bundled at $199.99/yr |
| Multi-property SaaS, needs WAF + analytics | 1–10 TB | Cloudflare Pro/Biz | Unmetered bandwidth, multi-zone management |
| Media streaming, software distribution, game patches | 25–2,000 TB | BlazingCDN | $2–$4/TB, predictable cost, enterprise SLA |
| AWS-native stack, tight integration required | Variable | CloudFront | Native S3/ALB integration, but $0.085/GB at low volumes |
The gap between Sucuri's sweet spot and high-volume CDN pricing is significant. A 50 TB/month workload on the Sucuri model is architecturally wrong — you'd need 50 separate site licenses, which would cost $9,999.50/year on Basic alone, with zero bandwidth guarantees. The same workload on BlazingCDN runs $350/month ($4,200/year) with a contractual commitment.
Sucuri doesn't price CDN by the terabyte. The effective cost depends on your plan tier and actual bandwidth consumption. On the Basic plan ($199.99/year), a site pushing 500 GB/month works out to roughly $33/TB. At 2 TB/month, it drops to about $8.33/TB. There are no published overage fees, but Sucuri reserves the right to contact high-bandwidth accounts under fair-use terms.
Yes. The standalone Sucuri Firewall plan ($9.99/month as of 2026) includes CDN delivery alongside the WAF. You don't need to purchase the full platform if you only need edge delivery and layer-7 protection. The platform plans add malware scanning, removal services, and faster SLAs.
Not explicitly. Sucuri uses a flat annual or monthly fee with no per-GB billing. However, the fair-use policy creates soft limits. Sites that consistently push large volumes may be asked to upgrade or negotiate a custom arrangement. Treat this as "unmetered with caveats" rather than truly unlimited.
Sucuri Basic at $199.99/year is cheaper than Cloudflare Pro at $240/year, but Cloudflare Pro offers unmetered bandwidth and a broader feature set for multi-site architectures. Sucuri's advantage is the bundled malware remediation, which no Cloudflare tier includes. For pure CDN cost, Cloudflare's free tier remains unbeatable for low-security-requirement sites.
For CMS-driven sites under 2 TB/month, Sucuri works well. Beyond that threshold, the lack of transparent bandwidth guarantees and per-site licensing model makes it impractical. High-traffic workloads — video, software delivery, large-scale SaaS — should use a CDN with explicit per-TB pricing and volume discounts.
Pull your last 90 days of CDN egress from your current provider's billing dashboard. Calculate your actual cost per TB, including overages. Then model the same traffic against Sucuri's flat rate, Cloudflare's tiered plans, and a usage-based provider like BlazingCDN. Most teams discover a 30–60% cost gap they didn't know existed — especially on workloads between 10 and 500 TB/month where neither free tiers nor enterprise contracts apply cleanly. The CDNPerf calculator is a useful starting point for back-of-envelope comparisons. But the real insight comes from mapping your own cache-hit ratios and origin-pull patterns against each pricing model. Do the math; the bill tells you what your architecture actually costs.
