Tight integration

Fastly and PerimeterX offer a tightly integrated solution on both the client and server level. When a request is made to your site or app, Fastly serves the content along with PerimeterX’s sensor (a JavaScript snippet on your site, or SDK in your mobile app). The sensor collects non-personally identifiable information from the browser at the network, user, and device layers.

Data collected is sent to the PerimeterX detector, where real-time algorithms are run to generate a risk score for user sessions. Fastly uses these risk scores to allow or deny access to your website, blocking suspected bot activity. You can also apply additional levels of control, such as further authentication or redirecting to a support page.

Powerful edge platform

Leveraging Fastly’s edge cloud platform, PerimeterX has built a solution that combines their advanced behavior-based bot detection with our rapid mitigation capabilities at the network edge. Fastly’s multi-terabit-per-second network manages millions of simultaneous connections globally, allowing us to operate as a distributed filter to enforce bot policies. Our cache nodes perform real-time evaluation of PerimeterX risk scores for request-by-request edge enforcement.

Highly accurate bot protection

The PerimeterX Bot Defender™ can protect you from a range of malicious bots, spanning basic scripts to more sophisticated bots that are adept at operating under cover of legitimate users. This includes highly sophisticated man-in-the-browser bots, which reside inside infected browsers and control users’ machines, or use advanced browser automation tools. These bots are detected by identifying suspicious user behavior patterns over time, such as repetitive, machine-like actions that are indicative of malicious bot activity. By offering advanced behavior-based detection, PerimeterX can identify more sophisticated application-layer bot traffic attacking specific functions like user logins or shopping carts.

Protect cached and origin content

Our joint offering protects both origin and edge traffic, so you can keep more in cache without the risk of bot abuse. Cache rapidly changing content like sports scores or inventory levels at the network edge for faster delivery, without worrying about content or price scraping. With Fastly’s Instant Purge and surrogate key purging, you can also proactively manage this content, swapping out outdated information instantly.

Maintain performance

Fastly and PerimeterX offer the lowest latency bot detection and mitigation solution on the market. The PerimeterX sensor is run in the background in asynchronous, non-blocking mode and cached on our CDN for zero impact on performance. Evaluating client requests at the edge and assigning a risk score only adds a few milliseconds; alternative bot detection solutions return to origin to evaluate and score bot traffic, adding significant latency and increasing backend server costs.
