3. Establish a set of rules or criteria to detect and block suspicious or unauthorized access attempts based on device and browser fingerprints. For instance, if a device or browser fingerprint triggers multiple failed access attempts within a short period, block further access from that fingerprint for a set duration.

   
   

4. Monitor the fingerprints collected over time and adjust rules as needed to minimize false positives. For example, if multiple legitimate users have similar fingerprints, consider refining the criteria for flagging suspicious activity.

   
   

5. Continuously update your fingerprinting tools and rules to stay ahead of evolving threats, new browser and device configurations, and changing user behavior patterns. Regularly review fingerprint analysis data, track trends, and make adjustments as needed.

   
   

By implementing a comprehensive device and browser fingerprinting strategy in collaboration with other anti-scraping techniques, public sector organizations can effectively prevent data scraping and protect sensitive information from unauthorized access.

Strategy 5: IP Geolocation and VPN Detection

What is IP Geolocation and VPN Detection

IP geolocation and VPN detection involve identifying and blocking users who are hiding their true location using proxy servers or Virtual Private Networks (VPNs). Data scrapers and attackers may use these services to obscure their actual location and avoid detection while attempting to access or scrape information from public sector websites.

How does it work

IP geolocation and VPN detection tools analyze the IP addresses of visitors to your website or online portal and detect whether they are accessing your site from a blocked location or using common VPN and proxy services to hide their true whereabouts. If a visitor's location cannot be accurately determined or appears to be obscured, their access can be restricted or blocked entirely.
