PerimeterX is a behaviour-based bot management solution that protects websites, mobile applications and APIs from automated attacks.

Who uses this technology?

General usage

PerimeterX offers various products to detect and manage automated attacks and client-side threats to web or mobile applications and APIs.

Bot Defender combines intelligent fingerprinting, behavioural signals and predictive analysis to detect bots on web and mobile applications and API endpoints. It then blocks the bots completely, rate-limiting them, or redirecting them to decoy sites.

Code Defender is a client-side application security solution that continuously protects your website from digital skimming, formjacking and Magecart attacks, stopping data breaches and reducing your risk of non-compliance.

Page Defender preserves the intended online shopper experience by blocking unwanted coupon extensions and ad injections.


Perimeter has won a veritable smorgasbord of awards for its innovative security solutions. Salesforce Ventures is one of its big name investors.

Marketplace benefits

CobbleWeb mostly uses PerimeterX’s Bot defender.  It protects our clients’ marketplaces from: 

  • Account takeovers – an attack in which cybercriminals take unauthorised ownership of online accounts using stolen usernames and passwords. 
  • Carding – cybercriminals use bots to test lists of recently stolen credit and debit card details on small purchases before buying high value items on ecommerce sites.
  • Skewed analytics – when your web traffic gets polluted by a high volume of non-human traffic.
  • Web scraping – bots crawl your site continuously to capture pricing data and product descriptions at scale. Competitors may use it to match or beat your pricing and take business away from you or steal your content.
  • Denial of Inventory – malicious hoarder bots add items multiple times to a shopping cart until it is shown out of stock. This is damaging to conversions, user experience and revenue.
