What is a Proxy Server?
A proxy server acts as an intermediary between your device and the internet. When you use a proxy, your web requests go through the proxy server first, which forwards them to the destination website. The website sees the proxy's IP address instead of yours.
Types of Proxies
- HTTP Proxy: Works only with web browsers and HTTP traffic. Doesn't encrypt data.
- SOCKS Proxy: Works with any type of traffic but is slower. SOCKS5 supports authentication.
- Transparent Proxy: Often used by organizations to filter content. Doesn't hide your IP.
- Anonymous Proxy: Hides your IP but may be detectable as a proxy.
Proxy vs VPN: Key Differences
- Encryption: Proxies don't encrypt traffic — VPNs encrypt everything with AES-256
- Coverage: Proxies work per-application — VPNs protect all device traffic
- Speed: Free proxies are slow and unreliable — VPNs like KernelVPN maintain near-native speeds
- Privacy: Many free proxies log and sell your data — KernelVPN has a verified no-log policy
- Security: Proxies can't protect on public WiFi — VPNs provide complete protection
Risks of Free Proxies
- Many inject ads into your browsing experience
- Some log and sell your browsing data to advertisers
- No encryption means your data is visible to anyone on the network
- Frequently blocked by major websites and streaming services
- Can contain malware that infects your device
