Leading Online Learning Platform

Eliminating Malicious Bots for Optimal Application Performance

Download Case Study


This leading, global online learning and teaching platform is used by 80% of Fortune 100 companies. It offers more than 150,000 courses in 65 languages and serves more than 50 million users worldwide.


Performance is key to the success of SaaS companies that deliver value to their customers entirely through online experiences. For this leading online learning company, application performance and site uptime was no exception — optimal performance was critical for its brand reputation, revenue growth and success. Initially, when the service was launched, the company encouraged users to consume as much content as possible to increase its popularity. The quest for hypergrowth and adoption led to users deploying bots to scrape and download content from the platform. The platform, which was primarily designed for streaming content, was unable to handle the flood of concurrent content downloads and was quickly overwhelmed, resulting in application downtime. Additionally, many users complained that their accounts were compromised. Users’ login and password combinations were being validated by brute force credential stuffing attacks on the login page, leading to malicious account takeover (ATO). As the team investigated, they also noticed a high number of bot-created fake accounts that were used to plagiarize content and post it on other platforms.

Bots were hurting both the user experience and the content publishers on the e-learning service, which ultimately slowed revenue growth. The company needed to resolve its application performance, user account security and content protection challenges quickly to ensure its continued leadership and growth in the e-learning market.

Bot Defender was able to identify these scraping bots, often the most sophisticated in their ability to mimic human behavior, and found they were typically operated by competitors who continuously improved them to steal content.

ATO bots: Using fake accounts and credential stuffing, ATO bots were also attacking the company’s login pages and taking over valid user accounts to steal content. Over 80% of the traffic to its login pages was from ATO bots. Bot Defender was able to identify and defend against these credential stuffing attacks before user credentials were revealed or validated.
