DDoS Protection for Ecommerce Stores & High-Traffic Sites
When checkout goes down, you lose orders by the minute. We harden your Cloudflare setup against volumetric and application-layer (L7) DDoS attacks, lock down your origin server, and hand your team a tested emergency playbook for peak-traffic days.
DDoS protection for ecommerce uses Cloudflare to absorb and filter malicious traffic before it reaches your store, so real customers can still browse and check out during an attack. Edgecraft configures multi-layer defenses — network (L3/4) and application-layer (L7) DDoS mitigation, rate limiting, WAF rules, bot mitigation, Under Attack Mode, and locked-down origin access — then documents an escalation and emergency playbook your team can run during peak traffic or a live incident. DDoS hardening starts from $2,500. No setup blocks 100% of attacks, so we combine Cloudflare with origin hardening and a tested response plan to keep impact and downtime low.
What is a DDoS attack on an ecommerce site?
A Distributed Denial-of-Service (DDoS) attack floods your store with fake traffic from many sources at once, trying to exhaust your bandwidth, server CPU, database connections or application resources until real shoppers can't load pages or complete checkout.
Why stores are a prime target
Ecommerce, SaaS and marketplace platforms are attractive targets because downtime is expensive and instantly visible. Attacks are launched for extortion, competitive sabotage, "stress-testing" by disgruntled actors, or as a smokescreen for fraud and credential-stuffing while your team is distracted.
Cloudflare sits in front of your store as a reverse proxy, so attack traffic hits Cloudflare's global network first — where it can be absorbed and filtered — instead of slamming directly into your origin server.
Two attack layers we defend
- Network layer (L3/4): volumetric floods — SYN floods, UDP/ICMP floods, reflection and amplification — measured in Gbps and Mpps.
- Application layer (L7): HTTP floods that mimic real users — hammering search, cart, login or product pages to exhaust your app and database.
L7 attacks are the hard ones for ecommerce: they look like real traffic, target your most expensive endpoints, and need smart rules — not just raw capacity — to stop.
How does Cloudflare DDoS protection actually keep my store online?
There's no single switch. Effective DDoS readiness layers several Cloudflare controls so an attack has to defeat all of them at once.
Always-on network mitigation
Cloudflare's anycast network absorbs and disperses volumetric L3/4 floods across hundreds of data centers, so no single point takes the full hit.
WAF & managed rules
A tuned Cloudflare WAF blocks malicious patterns and known attack signatures before they reach your application logic.
WAF setup →Rate limiting
Per-IP and per-path rate limits throttle abusive request bursts on costly endpoints — login, search, cart, checkout and APIs — without punishing genuine shoppers.
Bot mitigation
Many L7 floods are automated. Bot protection separates real browsers from scripted traffic, so the flood gets challenged — not your customers.
Bot protection →Under Attack Mode
A managed challenge layer that interposes a short verification on suspicious visitors during an active incident — buying your origin breathing room in seconds.
Origin lockdown
We hide and firewall your origin IP so attackers can't bypass Cloudflare and hit your server directly — the most common reason "protected" sites still go down.
When should I turn on Cloudflare Under Attack Mode?
Under Attack Mode is a powerful emergency lever — but it adds friction for every visitor, so it's not something to leave on permanently. We help you decide the trigger conditions and configure smarter, lower-friction defenses for everyday traffic.
- Use it when you're under an active L7 flood and normal rules aren't holding.
- Scope it narrowly — apply challenges to specific paths or suspicious traffic rather than the whole site where possible.
- Pair it with rate limiting and bot rules so you can dial protection up and down without a hard on/off.
- Document who can enable it and how, so a junior on-call person isn't guessing at 3am.
Beyond the panic button
Reaching for Under Attack Mode every time is a sign of a setup that isn't tuned. Our goal is that your day-to-day defenses — WAF, rate limits, bot rules and caching — handle most abuse automatically, and Under Attack Mode stays a deliberate, well-understood escalation step.
During an active incident you don't have time to learn the dashboard. Emergency Cloudflare support means an experienced specialist drives the response alongside you.
Emergency support →What should you prepare before a DDoS attack hits?
The worst time to design your defenses is during the attack. Most of the value is in preparation — done calmly, in advance.
1. Hide and firewall your origin
Rotate the origin IP, restrict it to Cloudflare's IP ranges with firewall rules or Authenticated Origin Pulls, and remove leaky DNS records that expose the real address.
2. Baseline your normal traffic
We measure typical request rates per path so rate limits and alerts are tuned to your store — not generic defaults that either miss attacks or block customers.
3. Pre-build your rule set
WAF rules, rate-limit rules, bot rules and an Under Attack Mode plan are staged and tested ahead of time, ready to enable in seconds.
4. Protect the expensive endpoints
Login, search, cart, checkout and APIs get specific protection, since these hurt most under L7 load and usually can't simply be cached.
5. Write the playbook
A clear, role-based escalation document: who watches dashboards, who pulls which levers, when to escalate, and how to communicate with customers.
6. Run a dry run
We walk your team through the playbook so the first time they use it isn't during a real, revenue-losing incident.
Is your store ready for Black Friday and peak-traffic spikes?
On high-revenue days the line between a legitimate traffic surge and an attack gets blurry — and over-aggressive rules can block paying customers just as easily as an attack can take you offline.
Why peak days need their own plan
During Black Friday, Cyber Monday, product drops, flash sales and ticket on-sales, your traffic can legitimately multiply 10x or more. Defenses tuned for a quiet Tuesday will misfire. Attackers also know these are the dates when downtime hurts most.
- Pre-event tuning of rate limits and caching for expected surge volumes
- A "peak mode" rule profile you can switch on for the sale window
- A cache strategy that serves product and category pages from the edge to shield your origin
- Monitoring and on-call escalation arranged before the event, not during it
Tuned for your platform
We tailor peak-traffic and DDoS readiness to the realities of each platform's checkout and caching behaviour.
Monitoring, escalation and the emergency playbook
Protection is only as good as your ability to notice an attack early and respond in a coordinated way.
Monitoring & alerts
Traffic, error-rate and origin-health alerting so you learn about an attack from a dashboard — not from angry customers on social media.
Escalation paths
A documented chain — detection, triage, mitigation — and clear rules for when to call in emergency support or escalate to your Cloudflare plan's higher tiers.
Live incident response
We can drive mitigation with you in real time — reading attack patterns, deploying rules, and adapting as the attacker changes tactics.

When Cloudflare is not enough: Cloudflare dramatically reduces the risk and impact of DDoS attacks by absorbing and filtering malicious traffic — but no provider blocks 100% of attacks, and a misconfigured origin or a vulnerable application can still be brought down. Real resilience also depends on secure development, regular patching, server hardening, a solid backup and recovery plan, and people ready to respond. We make Cloudflare do as much of the heavy lifting as possible, and we're honest about the gaps it can't cover.
How much does DDoS protection cost?
Indicative, starting-from pricing. Final cost depends on your traffic volume, number of domains, Cloudflare plan, attack history, complexity and the level of ongoing support you need.
Not sure where you stand? A Cloudflare audit (≈ £/€ equivalent) is the fastest way to find your exposure. For continuous monitoring and rule maintenance between incidents, see managed Cloudflare services. Already under attack right now? Go straight to emergency support.

Frequently asked questions
What is DDoS protection for ecommerce?
DDoS protection for ecommerce is a set of defenses — delivered through Cloudflare — that absorb and filter malicious traffic before it reaches your store, so legitimate shoppers can still browse and check out during an attack. It combines always-on network (L3/4) mitigation, application-layer (L7) filtering, rate limiting, WAF rules, bot mitigation and a locked-down origin, plus a documented monitoring and escalation plan for live incidents.
Does Cloudflare stop all DDoS attacks?
No. Cloudflare dramatically reduces the risk and impact of DDoS attacks by absorbing and filtering malicious traffic across its global network, and it stops the large majority of volumetric and application-layer floods. But no provider can promise 100% protection or guaranteed uptime outside a signed SLA. A misconfigured origin, a leaked IP address or a vulnerable application can still be knocked offline, which is why we pair Cloudflare with origin hardening and a tested response plan.
What is Cloudflare Under Attack Mode and when should I use it?
Under Attack Mode is an emergency setting that places a short managed challenge in front of suspicious visitors during an active attack, buying your origin breathing room within seconds. Because it adds friction for everyone, it's best used as a deliberate escalation step during a live L7 flood — ideally scoped to specific paths — rather than left on permanently. Day-to-day, well-tuned WAF, rate-limiting and bot rules should handle most abuse automatically.
What is the difference between L3/4 and L7 DDoS attacks?
Network-layer (L3/4) attacks are volumetric floods — SYN, UDP, ICMP and amplification — that try to saturate bandwidth and connections, measured in Gbps and Mpps. Application-layer (L7) attacks send HTTP requests that look like real users, hammering expensive endpoints such as search, cart, login and checkout to exhaust your app and database. For ecommerce, L7 attacks are usually the harder challenge because raw capacity alone won't stop them — you need smart, tuned rules.
How do I protect my origin server so attackers can't bypass Cloudflare?
Origin protection means making sure attackers can only reach your server through Cloudflare. We rotate or change the origin IP if it has been exposed, remove leaky DNS records, restrict the origin firewall to Cloudflare's published IP ranges, and enable Authenticated Origin Pulls so the server only accepts requests from Cloudflare. A bypassable origin is the single most common reason a 'protected' store still goes down.
How should I prepare my store for Black Friday or peak traffic?
Prepare before the event: baseline your normal traffic, tune rate limits and caching for expected surge volumes, pre-build a 'peak mode' rule profile you can switch on for the sale window, serve product and category pages from the edge to shield your origin, and arrange monitoring and on-call escalation in advance. On high-revenue days the gap between a legitimate surge and an attack is narrow, so rules must be tuned to avoid blocking paying customers.
How fast can you help during an active DDoS attack?
If you're under attack right now, use our emergency support so an experienced specialist can drive mitigation with you in real time — reading attack patterns, deploying and adjusting rules, and managing Under Attack Mode. Response is fastest when origin lockdown and a baseline rule set are already in place, which is exactly what the DDoS hardening project sets up ahead of time. Emergency support starts from $2,000.
How much does DDoS hardening cost?
DDoS hardening starts from $2,500, with a Cloudflare audit from $600 if you want to find your exposure first. Emergency, under-attack support starts from $2,000, and ongoing Managed Cloudflare Care starts from $1,000/mo. All pricing is indicative and starting-from — final cost depends on your traffic volume, number of domains, Cloudflare plan, attack history, complexity and support needs.
