Cloudflare's Traffic Control improves the availability and security of your online assets, such as websites or APIs, by providing extra protection against Layer 7 Denial of Service (DoS) attacks. Layer 7 DoS attacks send high volumes of HTTP requests designed to harm your application. Most of these attacks attempt to make your website or API inaccessible to legitimate users. Some attacks, such as brute-force, try to break through your login page by submitting credential combinations in high frequencies until they crack a legitimate password.
Bad actors continue to make their attacks appear more like legitimate traffic, making it increasingly difficult to block malicious requests without hurting real users. Traffic Control gives you granular controls to detect bad traffic, customized rulesets to ensure that your legitimate visitors are not impacted, and insights to improve your security posture as attackers evolve.
Traffic Control shapes how Internet traffic interacts with your application. Prevent brute force password cracking by setting a request threshold across login access points on your website or application. Suspicious IP addresses which trigger detection can be mitigated differently, based on threat level, to help ensure that legitimate users aren’t banned. As a result, real users can continue to login to your applications while truly bad traffic is stopped without consuming backend resources.
Stop abusive traffic targeting your APIs by creating sophisticated detection rules, such as flexible rate limiting thresholds, URI wildcards, and detection criteria based on authentication tokens and origin response. Custom error responses let you provide actionable information for legitimate clients to successfully reach your APIs. Rulesets take less than a minute to replicate throughout our global network.
For site-wide rate limiting, Traffic Control lets you configure a maximum number of requests per second across your entire website. Both your domain and subdomains are protected from volumetric requests coming from all IP addresses. Setting request thresholds using Traffic Control, which matches the capacities of your origin server, provides additional protection against attacks, which can bring down your application, website, or API.
Traffic Control insights provide information into the type of traffic being mitigated so you can fine-tune your security posture while ensuring availability to legitimate users. Traffic Control insights tells you which parts of your applications, clients, and geographies are mitigated the most, so you can continue to respond to evolving bad actors and their threats.
