Lead Forensics – Turn Anonymous Website Visitors Into Real Leads

Right now, businesses are visiting your website, browsing your services, and leaving without a trace. No form filled in. No email captured. No lead in your CRM. Lead Forensics closes that gap. It's the world's leading B2B visitor identification software, revealing exactly which companies are on your site in real time — so your sales team can reach out while interest is still hot, not days later.

What Lead Forensics does

Matches your website visitors' IP addresses against company databases, revealing which businesses are on your site — even when they never fill out a form.

Does this sound familiar?

Your sales team can't generate enough qualified leads.

Your marketing campaigns bring traffic, but that traffic never turns into real leads.

By the time you reach a prospect, they've already gone cold — or gone to a competitor.

You have no idea which companies are quietly checking you out.

You're flying blind on how B2B visitors actually behave on your site.

You keep burning ad and content budget on visitors who never convert.

Lead Forensics shows you who's visiting your website

Fill your CRM, grow your pipeline, and turn missed opportunities into revenue

Let´s talk about it

The technology behind it: reverse IP tracking

Most tracking tools ask "what domain does this IP belong to?" Lead Forensics flips the question: "which company does this IP address belong to?" That's a reverse IP lookup — a technique normally used in security and hosting verification, repurposed here to identify the businesses behind your website traffic. The result: GDPR-compliant, company-level data your sales and marketing teams can actually act on — no cookies, no personal data, no compliance headaches.

What you can do with Lead Forensics

Sales

While your sales team is on calls and buried in email, a potential client is browsing your site, unnoticed. Lead Forensics surfaces that visitor instantly and alerts your team. Backed by a database of over 4.5 million data points, it delivers the company name, location, and direct contact details of key decision-makers — phone number, email, LinkedIn profile — everything needed to open a conversation. It also syncs with your CRM, cross-checking visitors against your existing customers and sorting them by status, from active accounts to brand-new leads.

Sales

Account management

Get to know your prospects faster than ever. The dashboard shows not just who's visiting, but how they're engaging — which pages, which content, which interests — so you can spot upsell and cross-sell opportunities before your competitors do. Repeat visits trigger an alert too, telling your team exactly when to reach out.

Account management

Marketing

Great marketing runs on data, and Lead Forensics gives your team plenty. Beyond visitor behavior, you see exactly where each lead came from — the keyword that brought them in from Google, or the campaign that drove the click. That means real, measurable insight into what's working. Spot an untapped opportunity, and you can trigger an automated follow-up workflow for sales — no manual handoff required.

FAQs

What data can I access with Lead Forensics?

Lead Forensics provides insights into a wealth of important data for your lead management, starting with key company information such as company name, industry, and location. It also offers contact details for relevant decision-makers, including department, email address, phone number, and LinkedIn profiles. In terms of user behavior, Lead Forensics offers an overview of which websites have been visited, the amount of time spent on each page, how frequently each page was visited, as well as the bounce rate and click paths. Regarding your ongoing campaigns, the software also provides insights into the sources, such as Google or an email campaign, including which search terms and ads were clicked, as well as the UTM parameters used for campaign tracking.
Is Lead Forensics in compliance with GDPR?

Lead Forensics is fully GDPR-compliant, as it does not store any personal data of individuals and does not directly store or process IP addresses. Additionally, users always have the option to opt out and request complete data deletion.
Which CRM systems are compatible with Lead Forensics?

The software is compatible with all major CRM systems in the industry. This includes Zoho CRM for automatic lead nurturing and integration into sales funnel management, as well as Salesforce and HubSpot CRM for lead evaluation and the synchronization of user information with workflows. Microsoft Dynamics 365 can also be integrated with Lead Forensics for the direct transfer of leads to the sales team. Other compatible systems include Pipedrive for lead import and synchronization with sales, as well as SugarCRM, which allows for capturing and segmenting leads based on website activity.
Can Lead Forensics track mobile visitors?

Under certain conditions, Lead Forensics can also track mobile visitors comprehensively. This is especially possible when companies use a fixed IP, meaning employees access websites through the company network. If devices with a static company IP are used, data can also be tracked, as well as the tracking of mobile users via UTM parameters when they access your website through an email campaign or social media channel.
What’s the difference between Google Analytics and Lead Forensics?

The difference between the two tools lies in their tracking methods. While Google Analytics tracks the entire browsing behavior of users and stores personal data when cookies are accepted, Lead Forensics uses reverse IP tracking to detect only company data and contacts, providing more detailed information. From company names and contact details to the source of the visitor, Lead Forensics delivers all the data a company needs for lead generation. In contrast, Google Analytics offers only a general overview of user demographics and browsing behavior. While it helps assess website performance and identify broad target audiences, Lead Forensics provides deeper insights for customer acquisition.
How do users rate Lead Forensics?

Users consistently rate Lead Forensics on popular review platforms like Capterra, G2, and GetApp, where the software earns an average of 4.4 out of 5 stars. The standout features highlighted include its user-friendliness, ease of use and implementation, seamless integration with CRM systems, and the wide range of functions the software offers. Users also praise its excellent value for money and outstanding customer service.
