Web Application Firewall

Protect Web Applications From Attacks Without Changes to Your Infrastructure


Threats to websites and internet-facing applications continue to grow and evolve, with cyber criminals more capable than ever. To steal data, malicious hackers are targeting vulnerable web servers and internet-connected endpoints. Blocking harmful incoming web traffic with a powerful web application firewall (WAF) is one vital tool to protect your business from harmful incoming web traffic. The WAF market is quickly shifting toward an edge security platform approach that combines a variety of protections tailored for distributed hybrid and multi-cloud environments.

What is WAF?

A Web Application Firewall, or WAFs, protects against an ever-growing number of sophisticated web-based incursions and attacks that target web server programs and the sensitive or confidential data they have access to. A WAF filters and monitors HTTP traffic between a web application and the Internet. It typically protects web applications from attacks such as cross-site forgery, cross-site-scripting (XSS), file inclusion, and SQL injection, among others.

Every request to the WAF is compared against the rule engine and threat intelligence gathered from millions of websites being protected. Suspicious requests can be stopped, disputed, or logged according to the user’s needs, while genuine requests are sent to the destination, whether on-premises or in the cloud.

Get The Best Protection For Your Web Applications

Protect Your Web Properties

Protect your website from SQL injection, cross-site scripting (XSS) and zero-day attacks, including OWASP-identified vulnerabilities and threats targeting the application layer.

Secure Applications in the Cloud

Layered defense against DDoS, data compromise, and malicious bots that are fast, easy to deploy, and scalable. Benefit from cloud deployment without any extra hardware or software installation.

Prevent Data Leaks with API Security

Prevent sensitive data of stolen or hacked devices from being exposed by blocking traffic. Stop data leaks by disabling malicious IPs from abusing your APIs and preventing invalid requests.


Protection against automated attacks

Experience an Integrated WAF solution that keeps your applications and APIs secure and productive, thwarts DDoS attacks, keeps bots at bay, and detects anomalies and malicious attackers, all while constantly monitoring for browser supply chain attacks.

Integrated security and performance

Our WAF operates on the same global network as our performance product suite seamlessly integrate with DDoS protection, Bot Management, CDN, Load Balancer, Smart Routing, and more. Tight integration between products enables enhanced performance, as compared to legacy WAF solutions.

API integration

Rich API integration with popular toolsets allows for easy configuration, customizable analytics, and direct plug-ins for existing SIEM infrastructure. Examples include Terraform, GraphQL Splunk, SumoLogic, Datadog, and more.

High Accuracy

Our engineering team uses Cloudflare’s proprietary threat intelligence to regularly update Managed Rulesets. This allows us to constantly improve accuracy, experience fewer false positives and provide comprehensive coverage to protect against zero-day vulnerabilities.

Automated threat intelligence at scale

The global WAF distributed network and built-in automated threat risk scoring algorithms enable the system to curate a proprietary threat score by evaluating 1B+ IPs and analyzing digital signatures, every day.

Flexible control

Firewall Rules allow customers to create custom rules for their specific needs directly from the dashboard. The rules engine supports several functions, operators, and transformations; IP, geo-location, user-agent, OWASP Top-10, and more.

4 Reasons Why You Should Use Web Application Firewalls

1. Scale with your business

WAF solutions take advantage of the power and scalability offered by massive edge networks. Additionally, globally distributed points of presence help to ensure both minimum latency and maximum coverage. WAF quickly isolates endpoints from incoming threats.

2. Block attacks outside your perimeter

Cloud-based WAF helps to block malicious traffic long before it reaches your network, while also serving as a security perimeter outside of internal or cloud infrastructure. This helps to keep malicious traffic at a safe distance from the application and data servers.

3. Protect apps wherever they are hosted

Cloud-based WAFs provide a uniform security solution to protect all your apps, regardless of where they reside globally: on-prem data centers, private cloud, and multiple public clouds. WAF protects the network edge from malicious traffic and secures all internet-facing applications and APIs.

4. Low total cost of ownership

Cloud-based WAFs offer the highest level of web application security possible without requiring a significant upfront investment in resources or recurring costs for maintenance, hardware replacement, or software upgrades.

Benefits of WAF

Ease of deployment & maintenance

WAF is simple to set up and use to protect apps. There is no need to install additional software, configure DNS, handle SSL/TLS certificates, or set up a reverse proxy. Define and maintain rules in one place, then reuse them across all of the online applications that need to be secured.

Agile protection against web attacks

Hundreds of rules are supported by WAF, which can check any element of a web request with minimal latency impact on incoming traffic. When problems occur, WAF rule propagation and modifications take less than a minute, allowing immediate security updates.

Protection against zero-day exploits

WAFs are an important component of the layered security architecture that help prevent a Zero-day exploit, WAFs help patch any vulnerabilities virtually, protecting your infrastructure until the vendor releases a patch or you can patch the code your

Save time with managed rules

Start quickly and defend your web application or APIs against typical risks. WAF protects against the most frequent hacking methods and uses caching technologies to improve both site speed and performance.

Intelligent and automated risk management

Managed rulesets provide better safety by continuously studying distinctive data and IP repute on the web. Automated mitigations based on fingerprinting network flows and HTTP attack traffic detect and prevent attacks before they can cause any damage.

Improved visibility of web traffic

WAF provides near-real-time insight into your web traffic, allowing you to monitor everything from individual rules to full inbound traffic. WAF also includes robust logging, which records data for use in security automation, analytics, and audits.
