Stop competitors from getting your prices

  • Stop being outpriced. Customer acquisition costs are higher than ever. Why should you lose a costly customer acquisition just because your competitor always aligns itself $1 below your price?
  • Stop price wars. If your competitors react in near real-time to your prices, then anytime you lower a price, they will lower their price as well. Let competitors pick other opponents to run their price wars.
  • Drive competition crazy. Reverse-engineering BotDefender takes 1000 more time than setting it up. Keep competition distracted for months, while you make decisive moves on your core business.
  • It's free, no catch. The Express Plan is free and does not expire. No hidden costs or catch involved. We have a paid plan with extra features but the Express Plan is fully functional.

Tar pitting (Express Plan)

Tar pitting is the protection method made available by BotDefender in the Express Plan. The snippet returned by BotDefender contains the logic for a JavaScript callback to retrieve the price from the BotDefender servers. From the end-user viewpoint, the process is unnoticeable; it's merely a tiny extra call, much lighter than say, Google Analytics, or any similar web tracker.

Technically, it means that the HTML of your site does not contain the prices any more. Thus, it forces your competitors to request content from BotDefender servers. However, by doing this, they become very visible to us. Indeed, no real customers is going to grab hundreds (if not thousands) of prices every day from your site.

When BotDefender detects an automated retrieval attempt, that is, a number of requests that is abnormally higher than what a human could possibly need, BotDefender gradually slowdowns the delivery of the prices, that is, BotDefender throws your competitor into a tar pit.

Tar pitting is better than simply denying connections, because it's much more complicated to mitigate. Let BotDefender trigger all sorts of Heisenbugs in your competitor's scraping tools.

Obfuscation (Enterprise Plan)

Obfuscation is a more advanced protection method only made available in the Enterprise Plan. The snippet returned by BotDefender is an intricate price of HTML and JavaScript designed to be very hard to decipher, no matter if it's the raw HTML or the DOM (Domain Object Model) that are analyzed.

Advantages of obfuscation over tar pitting are:

  • Zero overhead caused by an extra HTTP request to be made by the end-user. The snippet is self-contained and does not require any external resources to be rendered as the price.
  • Zero downtime as the snippet is self-contained; it does not matter whether the BotDefender servers are up or down: the mechanism keeps working without any dependency on BotDefender.
  • Zero leakage when obfuscation is used Lokad cannot collect any information about your web traffic. As far as data leakage is concerned, it can't be made more secure than that.

Lokad recommends obfuscation for high-traffic websites.
