Knock vs. De-anonymization Tools

Most de-anonymization tools only tell you which company visited your site, leaving SDRs to guess who to contact. They rely on IP tracking and third-party data, often providing outdated, incomplete or irrelevant information.

Knock goes further.

It reveals contact-level on anonymous leads who engage with your content—on your website and beyond—but drop off before identifying themselves. Knock automatically builds a real-time prospecting list of high-intent leads and streams it directly to your CRM.  

Why Look for De-anonymization Alternatives?

  • Company-level identification isn’t enough – Traditional de-anonymization tools guess company identity using IP tracking, but don’t reveal actual contacts. SDRs waste time chasing the right people instead of engaging decision-makers.
  • Intent signals are often misleading – Most solutions rely on page views and time on site, but browsing a pricing page doesn’t mean someone is ready to buy. Knock tracks real engagement signals that indicate actual purchase intent.
  • Unqualified leads clutter CRM – Many tools push all site visitors into the CRM, even if they aren’t buyers. This clutters the system and forces sales teams to sort through low-intent accounts manually.
  • Slow, ineffective outreach loses deals – Without real-time workflows, SDRs get lead data days later-by then, prospects have likely already engaged with competitors. Knock delivers instant lead insights, so SDRs can reach out while interest is high.
  • No extra cost for intent signals – Most tools charge separately for de-anonymization and intent data. Knock includes both—at no extra cost.
