How Each Technology Works
At a glance, proxies and VPNs seem similar—both redirect your internet traffic through another server. The critical difference lies in what happens to your data along the way and which applications are affected.
How Proxies Work
Application Level: Only configured apps (browser, scraper) use the proxy
Encryption: Optional (HTTPS proxies only)
IP Change: Website sees proxy's IP
How VPNs Work
System Level: ALL device traffic goes through VPN tunnel
Encryption: Always encrypted (AES-256 typically)
IP Change: Your entire device appears at VPN location
The Fundamental Difference
A proxy works at the application level. You configure your browser, Python script, or specific software to route through the proxy. Your operating system, other apps, and background processes continue using your regular connection.
A VPN creates an encrypted tunnel at the system level. Once connected, every packet leaving your device—browser, apps, system updates, everything—travels through that encrypted tunnel. There's no configuration per-app; it's all or nothing.
Real-World Implication
Running 50 web scrapers? With proxies, each can use a different IP simultaneously. With a VPN, all 50 share the same IP—and one block affects everything. This is why proxies dominate data collection while VPNs excel at personal privacy.
Key Differences Explained
Encryption
VPNs encrypt everything by default. Proxies only encrypt if using HTTPS—and even then, metadata is visible.
Speed
Encryption adds overhead. Proxies without encryption are faster. Mobile proxies may add more latency.
IP Pool Size
Premium proxy providers offer millions of rotating IPs. VPNs typically have fixed server locations.
Ease of Use
VPNs offer simple apps for any device. Proxies need per-application configuration.
Traffic Coverage
VPNs protect everything. Proxies only cover configured applications—DNS may still leak.
Concurrent Sessions
Run thousands of proxy connections. VPNs typically limit simultaneous device connections.

2025 Market Reality
The proxy and VPN markets have diverged significantly. While VPN usage has actually declined in some regions, proxy demand—especially mobile proxies—continues accelerating. Here's what the data tells us.
VPN Market in 2025
Interestingly, US VPN usage dropped from 46% to 32% in 2025. Business VPN use fell to just 8%. Meanwhile, 61% of VPN usage now happens on mobile devices, reflecting changed work patterns.
Proxy Market in 2025
The proxy market is growing faster than ever. Mobile proxy segment alone reached $750M in 2025. AI-driven web scraping now represents over 36% of all website traffic—proxies make this possible.
Key Insight for 2025
While consumer VPN growth has slowed, enterprise proxy usage is exploding. 65% of companies now feed proxy-collected data directly into AI and ML systems. The convergence of AI and data collection is reshaping both markets.
Speed & Performance
Speed matters. Whether you're browsing, streaming, or running thousands of requests per second, latency impacts everything. Here's how proxies and VPNs actually perform.
Typical Latency Impact
Why Proxies Are Faster
- • No mandatory encryption overhead
- • Direct HTTP/SOCKS forwarding
- • Optimized for high-throughput operations
- • Server-side caching capabilities
VPN Speed Considerations
- • AES-256 encryption requires processing
- • Protocol overhead (OpenVPN, WireGuard)
- • WireGuard is 2-4x faster than OpenVPN
- • Server distance significantly impacts speed
For data collection at scale, proxy speed advantages compound. Running 1,000 requests through a datacenter proxy might take 10 seconds. The same through a VPN could take 30-60 seconds—plus you're limited to a single IP for all of them.
Security Deep Dive
Security needs vary dramatically by use case. Here's an honest assessment of what each technology actually protects—and what it doesn't.

Security Warning for 2025
72% of cybersecurity leaders are concerned about VPN security risks. In 2024, malware-laden fake VPN apps increased 2.5× quarter-over-quarter. EvilProxy helped steal 1.5 million Microsoft 365 logins—even bypassing 2FA. Trust your provider carefully.
Neither Protects Against...
Cost Comparison
Pricing models differ significantly. VPNs charge flat monthly rates. Proxies typically charge by bandwidth (per GB) plus optional port fees. Here's a realistic breakdown.
VPN Pricing
- Unlimited bandwidth
- 5-10 simultaneous devices
- Fixed server locations (50-100)
- One-click apps included
Proxy Pricing
Cost Reality Check
A $10/month VPN is great for personal browsing. But if you're running automated operations requiring 1,000+ IPs, proxy costs can reach $100-500+/month. The pricing reflects different use cases—personal privacy vs. commercial data operations.

The Final Verdict
There's no universal winner. Proxies and VPNs solve different problems.
Choose Proxies If You Need:
- • Multiple IPs simultaneously
- • Per-request IP rotation
- • Maximum speed for automation
- • Specific IP types (mobile, residential)
- • Integration with scraping tools
- • Scaling to thousands of connections
Choose VPNs If You Need:
- • Full device encryption
- • Protection on untrusted networks
- • Simple one-click privacy
- • Streaming geo-bypass
- • ISP-level privacy
- • Flat-rate personal usage
For most personal users, a VPN is the simpler choice. It just works, protects everything, and costs a predictable $10/month. For businesses doing data collection, automation, or account management at scale, proxies are essential—VPNs simply can't handle those use cases.
Many professionals use both: a VPN for personal browsing and security, plus proxies for work operations. They're complementary tools, not competitors.
