The list of threats to websites and internet-facing applications continues to grow. To steal data, malicious hackers are targeting web servers and internet-connected endpoints. Blocking harmful incoming web traffic with a powerful web application firewall (WAF) is one mitigation to protect your business from harmful incoming web traffic. The WAF market is clearly 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.

What is Risk and Compliance

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 is 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

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

Integrated security and performance

Our WAF sits on the same global network as our performance product suite and seamlessly integrates 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 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 leverages Cloudflare’s proprietary threat intelligence to update Managed Rulesets regularly. This allows us to continuously improve accuracy, lower 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 a number of 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 leverage the power and scalability of massive edge networks with globally distributed points of presence to ensure minimum latency and maximum coverage. WAF quickly isolates endpoints from incoming threats.

2. Block attacks outside your perimeter

Cloud-based WAF blocks malicious traffic long before it reaches your network and serves as a security perimeter outside of internal or cloud infrastructure, helping to keep malicious traffic a safe distance from the application and data servers.

3. Protect apps wherever they are hosted

Cloud-based WAF blocks malicious traffic long before it reaches your network and serves as a security perimeter outside of internal or cloud infrastructure, helping to keep malicious traffic a safe distance from the application and data servers.

4. Low total cost of ownership

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

Benefits of WAF

Web application firewall is an intelligent, integrated, and scalable solution to protect web applications from cyber attacks.

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 may 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

To prevent a Zero-day exploit, WAFs are an important component of layered security architecture. WAFs help patch the vulnerability virtually and protect your infrastructure until the vendor releases a patch or you can patch the code properly yourself.

What is Vulnerability Management?

Save time with managed rules

Start quickly and defend your web application or APIs against typical risks. WAF protects against the most frequent sorts of hacking attempts and uses caching technologies to improve 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 cause any damage.

Improved visibility of web traffic

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