When it came to Layer 7 protection, StormWall provided the best protection at the lowest cost. Even providers whose licenses cost thousands of dollars couldn't deliver the same results.

Rock-solid protection
from the start

Reason #1

Specialist, not generalist

DDoS protection is our core business for 13 years. We are after one thing: stopping attacks. WAF and Antibot make it complete.

Reason #2

Managed by humans

Our engineers tune your WAF, write your bot rules, and watch your dashboards. You don't configure security. You run a business.

Reason #3

0-0.1% false positives

Lower than industry average. Real customers reach checkout. Real traffic reaches your origin. Quiet confidence, not loud challenges.

Reason #4

Transparent economics

You pay for clean traffic only. No surprise Enterprise walls, no "contact sales" for critical features. Same protection on every tier.

Reason #5

Deploy in minutes

DNS change? Done. No agents, no SDKs, no code. Go live even in the middle of an attack. SSL-transparent option keeps your keys yours.

Reason #6

15-minute SLA

We are always here to handle everything. The answer takes minutes because the engineer already knows your stack.

Fintech Banking Payments

When transactions stop,
the market knows in minutes.

Tight SLAs, strict auditors. An hour of degraded checkout shows up in the quarterly report. A login-flow credential-stuffing wave shows up in the news.

99.8%

Card testing blocked

Key risks

Transaction API flooding — L7 floods on payment and auth endpoints during peak volume.

Credential stuffing at scale — automated login replay coordinated with carding and money laundering.

Card testing on checkout — stolen cards validated in bulk before dark-market resale.

PCI DSS key exposure — handing SSL keys to your vendor can invalidate compliance.

How we protect

Anti-DDoS · L7 edge

Advanced WAF · API & fraud rules

Antibot · JA3/JA4 fingerprinting

SSL-free filtering · PCI DSS-friendly

PCI DSS SOC 2 ISO 27001 SWIFT CSP

E-commerce Retail

Black Friday doesn't wait
for your WAF tuning.

Retail spikes 10–40× on peak days. Scrapers, card-testers, and coupon bots mix with real customers. Every false-positive block is a lost sale.

99.96%

Real customers preserved

Key risks

Price & inventory scraping — competitor bots pulling data minutes after a launch.

Coupon & loyalty abuse — automated redemption across fake accounts.

Checkout DDoS on peak days — L7 floods timed to Black Friday / Prime Day.

False positives killing revenue — a 2–5% WAF misfire on 10M sessions = 200k–500k bounced checkouts.

Key risks

Volumetric floods on match servers — UDP/NTP/SYN during peak play.

Media Streaming News

Election night is
the worst time for a ticket.

Media serves the world on the minutes that matter most. That's exactly when scraping, L7 floods, and content theft peak.

+340%

Peak traffic served

Key risks

Breaking-news traffic spikes — 10–100× regular load within minutes.

Content scraping & republishing — paywalled content pulled at scale.

State-level censorship attacks — politically-timed DDoS on reporting windows.

Paywall bypass automation — headless browsers rotating IPs to dodge limits.

How we protect

Anti-DDoS · spike absorption

Antibot · scraping & paywall

CDN-ready integration

SaaS API platforms

Your SLA is
everyone else's SLA.

When you're a platform, one attack cascades into outages across hundreds of customer apps. Uptime is contractual with teeth.

99.996%

Key risks

API flooding & abuse — rate-limit evasion at scale across rotating sources.

Tenant-to-tenant propagation — a compromised tenant attacking the platform.

Credential stuffing on SSO — leaked passwords replayed at scale.

Zero-day exploit spray — a new CVE swept across every exposed instance.

The threat model starts

Public infrastructure attracts the most sophisticated attackers on earth. Legal and regulatory constraints require regional data residency.

Key risks

Politically-timed DDoS campaigns — synced with elections and announcements.

Citizen-portal defacement — SQLi/XSS for data access or public embarrassment.

Key risks

Customer-directed volumetric floods — multi-Tbps saturating your uplinks.

Booter marketplace activity — rented devices on your network attacking elsewhere.

Upstream transit congestion — attacks spilling onto peering links.

Downtime isn't loss.
Downtime is exit liquidity.

Downtime during volatility means users switch to competitors permanently. Plus drainer bots, sniping, and 2FA-bypass attempts.

Multi-layer catch — DDoS thinned the flood, the WAF inspected the survivors, Antibot fingerprinted the toolkit. Real users never queued.

See the result

SQL Injection

DDoS Protection Not applicable — valid single request

What is website DDoS protection?

StormWall for Web analyzes and filters all incoming traffic across OSI layers L3–L7. Malicious or “junk” requests are blocked, while only legitimate traffic reaches your website or web application.

Connection is performed via proxying, with no need to change your hosting provider. If you use your own networks (BGP), protection can be configured without changing your IP address. After activation, your website is protected from DDoS attacks and malicious traffic targeting both network and application layers.

What types of L3–L7 DDoS attacks does StormWall block?

StormWall protects websites and web applications from both network-layer and application-layer DDoS attacks. At the network level, the service mitigates attacks such as SYN Flood, UDP Flood, ICMP Flood, TCP Reflection, and amplification attacks including NTP, DNS, and SSDP. At the application layer, StormWall blocks HTTP Flood attacks (GET/POST), Slowloris, and other sophisticated attacks, including bot-driven traffic.

Who is website DDoS protection suitable for?

StormWall for Web is suitable for any organization that operates a website or web application, including retail and e-commerce companies, government organizations, media platforms, financial institutions, insurance providers, and more. The solution scales to any traffic volume and adapts traffic filtering to the specific characteristics and needs of each business.

How is StormWall website protection different from standard ISP DDoS protection?

Unlike basic provider-level protection, StormWall uses dedicated filtering centers, intelligent traffic analysis, and machine learning technologies. Our engineers develop tailored protection scenarios for each client. In addition, we offer a full set of solutions for comprehensive web application protection, including Antibot, WAF, and CDN, ensuring security across all layers from L3 to L7. Protection can be configured both with and without SSL certificate disclosure, while maintaining PCI DSS requirements and keeping confidential data secure.

How quickly can website DDoS protection be activated?

We recommend enabling protection in advance, as the cost of recovering from a serious incident is always higher than the cost of prevention. StormWall for Web DDoS protection can be connected in as little as 10 minutes, allowing fast deployment and immediate protection of web resources from DDoS attacks.
