Business Problem

According to the Cardekho team, competitors were actively scraping the car listings info every second and were making appropriate changes to their listings whenever there was a revision on the website.

It was noticed that a considerable part of the incoming traffic was bot infested, leading to the theft of proprietary content for competitive intelligence.The Cardekho team was convinced that these were bots as the changes reflected were real time and could not have been a human action in any possible way.

Such a malicious bot activity resulted in the disruption of genuine user traffic and depleted the revenue stream. Tracking these bots manually was a tedious task and with time these bots would evolve with more intelligence to escape IP blocking and blacklisting. At this point, Cardekho decided to intervene the shady situation by employing a reliable and a consistent solution that can effectively protect the website content from bots.

ShieldSquare Solution

Cardekho’s technology team had a clear agenda of tackling the bots negatively affecting their business. They decided to evaluate ShieldSquare in order to secure the car listings from theft.The solution had to be easy to integrate (plug and play) to cut infrastructure costs and quick in filtering traffic to ensure better performance. ShieldSquare was chosen owing to its exceedingly fast responsiveness in combating bad bots.

Post integration, ShieldSquare was deployed to monitor and assess the quality of the complete site traffic. It was noticed that most bots visiting the site cleverly emulated human behavior, thereby scraping the listings at a very high speed. By means of user behavior analysis and device fingerprinting, ShieldSquare was able to precisely identify the source and intent of the bot traffic.

As the bot patterns were recognized, Cardekho decided to challenge all bad bots with CAPTCHA and consequently block them from accessing the site listings. ShieldSquare ensured that no genuine users are shown CAPTCHA by means of leveraging bot intelligence across sites and big data analytics. Soon after the successful implementation of ShieldSquare, Cardekho is now able to identify 100% of the malicious traffic with zero false positives.
