How we make this list: we compare pricing pages, product documentation and public user reviews. Ratings come from G2, Capterra or Trustpilot, with the date we checked them.
Key takeaways
- Incapsula is now part of Imperva, so most buyers compare its replacement against Cloudflare, Akamai and Fastly instead of the old brand name.
- Cloudflare is the easiest starting point for small teams because its free plan already covers CDN caching, unmetered DDoS mitigation and a managed firewall.
- Akamai and Amazon CloudFront suit large sites with heavy traffic, but both are priced by contract or by usage, so small sites should budget with care.
- Sucuri fits WordPress owners who want malware cleanup bundled with the firewall, while KeyCDN and Bunny.net suit developers who want simple per-gigabyte pricing.
- If you need a managed web application firewall with expert support, compare Sucuri and Imperva-style enterprise plans against Cloudflare Business before you sign.

The best Incapsula alternatives

Starting price$20 per month
Free planYes
Cloudflare is the default answer for most teams leaving Incapsula, and the reason is simple. You change your DNS to Cloudflare, and traffic starts passing through its network within minutes. The free plan already includes content caching, unmetered DDoS mitigation and a basic managed firewall, which is more than many paid plans offered a few years ago. For a small business site, that is often enough on its own.
Paid plans add what growing sites actually need. Pro at $20 per month adds 20 custom firewall rules, image optimization and faster support. Business at $200 per month adds 100 custom rules and advanced bot detection. The catch is that the most powerful features, such as custom SSL uploads and advanced rate limiting, sit on Business or Enterprise plans. Teams that need fine control over firewall logic should test the rule builder during a trial before committing.
What we like- Free plan covers CDN and DDoS protection
- Huge global network
- Simple DNS setup
Watch out for- Advanced firewall rules need paid plans
- Support on free plans is limited

Free planNo
Akamai runs one of the largest delivery networks ever built, and that scale is its main selling point. Banks, media companies and large retailers use it because it can absorb very large attacks and serve traffic close to users almost everywhere. Its security products cover web application firewall rules, bot management and API protection, and they pair with detailed reporting that security teams like.
The trade-off is complexity and cost. Akamai does not publish simple monthly prices, so you negotiate a contract based on traffic and features. Small teams often find the sales process slow and the minimum commitments high. If your site serves millions of visitors or handles regulated traffic, that effort pays off. If you run a single marketing site, a simpler provider will serve you better.
What we like- One of the largest edge networks in the world
- Strong enterprise security controls
- Deep analytics
Watch out for- Pricing is quote-based and opaque
- Setup is heavier than Cloudflare
Starting price$0.12 per GB
Free planFree trial
Fastly appeals to teams that treat their CDN as code. Its edge platform lets developers write logic in VCL or Rust-based Compute, purge cached content instantly across the globe, and watch traffic in real time. That control matters for sites with fast-changing content, such as news pages, product catalogs and live dashboards. The Next-Gen WAF, built from the Signal Sciences product, adds strong application security for teams that need it.
Pricing starts around $0.12 per GB for the first 10 TB in North America and Europe, with lower rates at higher volume. That is easy to forecast for moderate traffic but can surprise teams with sudden spikes, since there is no flat monthly cap. Fastly also charges separately for some security features, so compare the full bundle, not just the CDN rate, when you price it against Cloudflare or Sucuri.
What we like- Programmable edge with instant cache purging
- Strong developer tooling
- Real-time logs
Watch out for- Per-gigabyte pricing adds up at scale
- Security add-ons cost extra
Starting price$0.085 per GB
Free planFree trial
If your site already runs on AWS, CloudFront is the natural replacement for Incapsula. It pulls content straight from S3 buckets, load balancers and EC2 origins, and it works with AWS WAF for firewall rules and AWS Shield for DDoS protection. Data transfer starts near $0.085 per GB in the United States for the first 10 TB, and new accounts get 1 TB of free transfer each month for the first year.
The catch is that CloudFront on its own is only a CDN. Firewall rules come from AWS WAF, which costs $5 per web access control list per month plus $1 per rule and $0.60 per million requests inspected. Shield Advanced, the managed DDoS service, is a much larger commitment. Teams that already use AWS accept this split happily. Teams outside AWS may prefer a single-vendor bundle from Cloudflare or Sucuri.
What we like- Tight fit with AWS services
- Pay-as-you-go pricing
- 1 TB free for the first year
Watch out for- WAF and Shield Advanced add cost
- Console setup takes learning
#5Sucuri
Best for: WordPress site owners3.3/5 on

Starting price$229 per year
Free planNo
Sucuri is the closest match for site owners who valued Incapsula for security rather than raw speed. Its platform plans start near $229 per year and combine a website firewall, CDN caching and malware scanning. The standout feature is cleanup: if your site gets hacked, Sucuri's team removes the malware and helps restore the site, which is a service most CDN vendors do not offer at this price.
The firewall-only plans start lower, near $9.99 per month per site, but the platform plans are the better comparison for Incapsula buyers. Sucuri focuses heavily on WordPress, Joomla and similar content systems, so owners of those sites get monitoring tuned to their stack. The dashboard is less polished than Cloudflare's, and reporting is simpler, but for a small team that wants security handled by someone else, that simplicity is a plus.
What we like- Malware cleanup included
- Firewall plus CDN in one plan
- WordPress expertise
Watch out for- No free plan
- Dashboard feels dated next to Cloudflare
Starting price$0.04 per GB
Free planFree trial
KeyCDN keeps things deliberately simple. You pay $0.04 per GB for traffic in North America and Europe for the first 10 TB, with higher rates in Asia, Oceania, Africa and Latin America, and a $4 monthly minimum. Setup takes minutes, and the control panel shows traffic, cache status and zone settings without extra layers. A 14-day trial lets you test performance before paying.
What you do not get is deep managed security. KeyCDN offers DDoS protection, bot blocking and secure token access, but it is not a full managed WAF service with expert rule tuning. That makes it a good fit for developers and content sites that need fast, cheap delivery and handle application security elsewhere. If you need a team watching your firewall, pair it with a dedicated WAF or pick Sucuri instead.
What we like- Clear per-gigabyte pricing
- Fast setup
- WordPress plugin available
Watch out for- No managed WAF depth
- Minimum $4 per month
Starting price$0.01 per GB
Free planFree trial
Bunny.net has built a following by charging very little for delivery. Traffic in North America and Europe starts at $0.01 per GB with a $1 monthly minimum, and the service includes storage, image optimization and a video streaming product. For blogs, documentation sites and small video libraries, the monthly bill often stays in single digits.
Security is present but basic: DDoS protection and standard controls come with the CDN, yet there is no managed WAF team or malware cleanup service. That is fine for sites where speed and cost matter most and where application security lives in the app itself. Teams replacing Incapsula mainly for its firewall should treat Bunny.net as a delivery layer, not a security replacement, and budget for a separate WAF if they need one.
What we like- Very low per-gigabyte rates
- $1 monthly minimum
- Video streaming support
Watch out for- No free plan
- Security features are basic

Gcore is a European provider that has grown into a solid global option. Its CDN includes 1 TB of free traffic each month, with paid traffic from about 0.01 euro per GB after that, which makes it easy to try without a card commitment. The network is strong across Europe and the Middle East, and it offers video streaming, DDoS protection and a web application firewall as add-ons.
US buyers should check point-of-presence coverage for their main audiences, since Gcore's brand is less established in North America than Cloudflare or Akamai. For sites with a European audience, or for teams that want a free tier larger than Cloudflare's feature set allows, Gcore is a credible alternative. Confirm the paid rate for your regions before migrating, since regional pricing differs.
What we like- 1 TB free each month
- Strong European coverage
- Video and security add-ons
Watch out for- Pricing past the free tier varies by region
- Smaller brand recognition in the US
How we chose
We compared providers on the things Incapsula buyers actually replace: CDN speed, DDoS protection, firewall depth, pricing clarity and setup effort. We used vendor pricing pages and recent comparison guides for rates, and we favored providers with current, public pricing over quote-only enterprise tools where a clear price was available. We did not claim hands-on testing. Instead we weighed published features, free tiers, support models and the fit for small, mid-size and enterprise teams, then checked that each listed provider still offers its CDN and security products today.
What to check before you switch
Start with your threat model, not the price list. A blog that needs fast pages and basic bot filtering has different needs from a checkout site that stores payment data and faces targeted attacks. List the attacks you have actually seen, such as credential stuffing, form spam or layer 7 floods, and match them to a provider's firewall and bot features.
Next, test migration on a staging domain. Change DNS for one low-risk property, watch cache hit rates and origin load for a week, and confirm that firewall rules do not block real users. Check how each provider handles SSL certificates, since some plans charge for custom certificates while others include them. Finally, read the support terms: free plans usually mean community support, while incident response and named engineers sit on paid tiers. A cheap plan with slow support can cost more during an outage than a pricier plan with a fast response team.
Frequently asked questions
Is Incapsula still available as a product?
Incapsula is now sold under the Imperva brand, so new buyers shop for Imperva application security rather than a standalone Incapsula product. Existing Incapsula customers were moved into Imperva's platform, and the old name now appears mainly in older guides.
Which Incapsula alternative is cheapest for a small site?
Cloudflare's free plan is cheapest, since it costs nothing and covers CDN caching plus DDoS protection. Bunny.net and KeyCDN are the cheapest paid options for sites that outgrow free tiers, with per-gigabyte rates starting near $0.01 and $0.04 respectively.
Do I need a separate WAF if I use a CDN?
It depends on your risk. A CDN alone protects against volumetric attacks and speeds up pages, but it does not inspect application traffic the way a WAF does. Sites with logins, forms or payments should run a WAF, either bundled with the CDN or as a separate layer.
How long does it take to migrate from Incapsula?
DNS changes usually propagate within a day, but plan for a week of testing. You need time to copy firewall rules, confirm cache behavior, test checkout and login flows, and watch for false positives before you point all traffic at the new provider.
Is Akamai worth it for a mid-size business?
Akamai is usually more than a mid-size site needs, since pricing is negotiated and minimums can be high. Mid-size teams often get better value from Cloudflare Business or Fastly, and they can move to Akamai later if traffic or compliance needs grow.
