What Is Similarweb?
Similarweb is a comprehensive digital intelligence platform that provides website analytics, traffic data, competitive analysis, and market research tools. It processes billions of data points daily to offer insights into website performance, audience demographics, traffic sources, and industry trends. In 2026, Similarweb serves over 500,000 users including digital marketers, SEO professionals, investors, and enterprise strategy teams, making it an indispensable tool for competitive intelligence and market analysis.
The platform offers several key features: Website Analysis (traffic sources, engagement metrics, geographic distribution), Industry Analysis (market trends, competitive landscape), App Intelligence (mobile app performance), and Stock Intelligence for publicly traded companies. Users can analyze any website's estimated traffic, identify top referring sites, discover keyword strategies, and monitor competitors' digital marketing campaigns.
However, accessing Similarweb—especially for monitoring competitors or conducting sensitive market research—exposes users to privacy risks and legal considerations that make VPN protection essential.
Why You Need a VPN for Similarweb in 2026
Protecting competitive research
Your Similarweb queries reveal which competitors you're monitoring, what market segments interest you, and your strategic priorities. On public Wi-Fi, this intelligence can be intercepted by sophisticated attackers or competitors.
Bypassing network restrictions
Many corporate networks block competitive intelligence tools. A VPN masks Similarweb traffic as standard HTTPS, restoring access for legitimate business research.
Eliminating ISP throttling
Internet providers may throttle data-heavy analytics platforms. A VPN removes these artificial speed limitations for faster report generation.
Securing API credentials
Similarweb offers API access for automated monitoring. A VPN protects these valuable credentials from interception during transmission.
Accessing global data
Some Similarweb datasets are region-specific. A VPN allows you to view unbiased international market data without location-based filtering.
