Why Your ISP Tracks You -- and How to Stop It
Your internet provider logs more about you than you might expect. Learn what data ISPs collect, why they collect it, and how a no-logs VPN like Nexun keeps your browsing private.
What Data Does Your ISP Actually Collect?
Every time you visit a website, stream a video, or send an email, your internet service provider can log metadata about that activity. This typically includes the IP addresses you connect to, the timestamps of connections, and the volume of data transferred. With unencrypted DNS queries, ISPs can also see the domain names you request -- essentially your browsing history. This data is valuable for ad targeting, sold to data brokers, and retained to comply with government data retention laws.
Why ISPs Collect and Retain Your Data
- Legal compliance: national laws in most EU countries require ISPs to retain connection metadata for 6-12 months for law enforcement access.
- Commercial use: several large ISPs operate advertising subsidiaries that use browsing data to build audience profiles.
- Network management: traffic analysis helps ISPs optimise their infrastructure and identify congestion.
What Can ISPs See With and Without a VPN?
Without a VPN, your ISP can see every domain you visit, your connection timestamps, and your approximate location based on your IP address. With Nexun active, your ISP sees only an encrypted WireGuard connection to a Nexun server -- nothing else. The destination, content, and timing of your actual activity are completely hidden.
Data Brokers and the Secondary Market
In many countries, ISPs are permitted to share anonymised or aggregated browsing data with third parties. In practice this data is rarely truly anonymous -- browsing histories are highly personal and re-identification is straightforward with enough context. Data broker firms purchase this data and build detailed consumer profiles used by insurers, employers, and advertisers.
How Nexun Protects You
Nexun uses WireGuard, the fastest and most modern VPN protocol available. All traffic between your device and Nexun's servers is encrypted with state-of-the-art cryptography. Nexun operates a strict no-logs policy: no connection timestamps, no IP addresses, no session data is ever written to disk. Your ISP sees only an opaque encrypted stream with no usable metadata.
Practical Steps to Protect Your Privacy
- Use Nexun on all your devices -- router, phone, laptop -- so every connection is covered.
- Enable encrypted DNS (DNS-over-HTTPS or DNS-over-TLS) alongside your VPN for an extra layer.
- Avoid browser extensions from unknown publishers -- these can bypass VPN protection at the application layer.
- Check your ISP's privacy policy annually; data practices change when companies are acquired.
FAQ
Can my ISP see what I do online even if I use HTTPS?
HTTPS encrypts the content of your traffic but not the metadata. Your ISP can still see which domains you visit, when, and how often -- just not the specific pages or content. A VPN like Nexun hides even this metadata.
How long does my ISP keep my data?
Retention periods vary by country, but most EU states require ISPs to keep connection metadata for at least 6 to 12 months. Some categories of data may be kept longer for billing or dispute purposes.
Does using Nexun prevent government surveillance?
Nexun significantly reduces your exposure. Because Nexun keeps no logs, there is no data to hand over even under a legal order. However, no tool provides absolute protection against a determined nation-state adversary. For most users, Nexun offers robust and practical privacy protection.
