1. How Streaming Platforms Detect VPNs
Streaming platforms don't want to block VPNs because they're evil. They block VPNs because licensing agreements force them to. Content rights are sold by territory, and if Netflix UK streams a show they only have US rights for, they've breached contract. The studios care deeply about this. Netflix doesn't, but they have to enforce it anyway.
The technical methods they use have evolved considerably. IP blocklisting is the oldest technique: streaming services maintain databases of known VPN server addresses and simply refuse connections from those IPs. This is why VPN providers need large server fleets and regular IP rotation. If your provider has 100 servers across 20 countries, the platforms will eventually blocklist most of them. If they have 7,700 servers across 111 countries, the game becomes harder to win.
DNS fingerprinting is subtler. When you request www.netflix.com, your device queries a DNS server. If that DNS response comes from a VPN provider's DNS infrastructure but your IP claims to be a residential address in Manchester, the platform knows something is off. Modern VPNs run their own DNS servers to prevent leaks, but this creates a fingerprinting opportunity. The solution is using DNS servers that appear to be ISP-operated or residential, which requires infrastructure investment most providers haven't made.
Deep packet inspection is the nuclear option. By analysing the structure of encrypted traffic, platforms can identify VPN protocols even without decrypting the payload. OpenVPN has distinctive packet patterns. So does older WireGuard (WireGuard Project, 2020). This is why obfuscation matters: protocols that disguise VPN traffic as regular HTTPS become harder to fingerprint. It's an arms race, and most VPN providers are losing. For a broader look at how VPNs, proxies, and Tor each handle detection differently, see our VPN vs Proxy vs Tor comparison.

2. NordVPN: Infrastructure Scale Wins the IP Blocklist Game
NordVPN runs 7,700 servers across 111 countries. That's not marketing fluff, it's the reason they consistently bypass streaming blocks. When Netflix blocklists one IP range, Nord rotates to another. The platform has to play whack-a-mole with thousands of servers, and they can't keep up.
The protocol matters too. NordVPN's WireGuard implementation, called NordLynx, adds a double-NAT system to address WireGuard's core limitation: the protocol requires storing user IP addresses on the server for routing (WireGuard Project, 2020). Nord's approach dynamically assigns a local NAT IP when you connect, then discards it when you disconnect. This means faster handshakes than OpenVPN (typically 100ms vs 300ms) with better obfuscation characteristics. Streaming platforms have a harder time fingerprinting NordLynx traffic compared to standard OpenVPN patterns.
Price:
The limitation is transparency. Nord claims a no-logs policy and has published independent audits (Cure53, 2023), but Panama's legal opacity means you're trusting the company's word more than Switzerland or Sweden's legal framework would require. For streaming, that's a minor issue. For dissidents, it's a bigger one. Our Privacy Trinity analysis covers the trust trade-offs between Nord, Proton, and Mullvad in detail.

3. ProtonVPN: Swiss Jurisdiction with Secure Core Architecture
ProtonVPN operates 3,000 servers across 70 countries. That's fewer than Nord but still substantial. Where Proton differentiates is jurisdiction and architecture. Switzerland's Federal Data Protection Act is among the strongest in the world (Swiss Federal Council, 2020), and Proton is legally incorporated there. When Swiss authorities requested user data in 2021, Proton could only provide the timestamp of the last connection because that's all they log. The jurisdiction actually protects you.
Secure Core is Proton's architectural answer to infrastructure compromise. Standard VPNs route your traffic through one server in the target country. If that server is compromised or coerced, your traffic is exposed. Secure Core routes traffic through two servers: first through a hardened server in a privacy-friendly jurisdiction (Iceland, Switzerland, Sweden), then to the exit server in your target country. This means even if the exit node is compromised, the attacker only sees traffic coming from Proton's secure infrastructure, not your real IP.
For streaming, this adds latency (typically 50-100ms more than a direct connection), but it works. The server count is high enough to rotate IPs effectively, and Proton's Stealth Protocol obfuscates VPN traffic to look like regular HTTPS, making deep packet inspection harder.
Price:
4. Mullvad VPN: Maximum Privacy, Minimum Server Count
Mullvad operates 600 servers across 40 countries. That's an order of magnitude fewer than Nord. For streaming, this is a problem. With fewer servers, platforms can blocklist Mullvad's IPs faster than they can rotate them. If you're trying to unblock Netflix US, you might succeed today and fail tomorrow, depending on how recently the IP range was blocklisted.
What Mullvad does have is the strongest privacy architecture in the consumer VPN market. No email required. No name. They mail you an account number. Five euros per month, no discounts, no matter how long you subscribe. Payment methods include cash in an envelope. The Swedish jurisdiction is strong (GDPR enforcement, no mandatory data retention), and Mullvad's no-logs policy has been tested in practice: Swedish police raided their offices in April 2023 and left empty-handed because there was nothing to seize (Mullvad VPN, 2023).
DAITA v2 (Defence Against AI-Guided Traffic Analysis) is Mullvad's answer to machine learning-based traffic fingerprinting (Mullvad VPN, 2023). It adds cover traffic and random packet delays to make timing analysis harder. This is overkill for streaming but critical for journalists and activists. Score: 4.47 out of 5, reflecting strong privacy but weaker streaming performance.
If your threat model is 'I want to watch UK television from Spain', Mullvad is overengineered and underprovisioned. If your threat model is 'I want to research surveillance companies without being logged', it's the correct choice. For more on what VPNs can't protect against, see our VPN limitations guide.
5. Comparison Table: Infrastructure vs Privacy vs Price
The table shows the central trade-off: server count correlates with streaming reliability, but jurisdiction and protocol design determine privacy strength. NordVPN wins on infrastructure scale. Proton balances scale with Swiss legal protection. Mullvad prioritises privacy over server proliferation. For a full side-by-side breakdown of all providers, use our VPN comparison tool.
6. The Providers That Don't Work
The data includes several low-scoring VPNs: Speedify (2.35/5, 50 servers in 50 countries), UltraVPN (2.33/5, 100 servers in 20 countries), Norton Secure VPN (2.04/5, 200 servers in 30 countries). These are not serious streaming tools.
Why? Server count matters, but so does IP reputation. Budget VPNs often lease server space from the same few hosting providers. When Netflix blocklists one provider's IP range, they blocklist everyone renting from that provider. Nord and Proton operate their own infrastructure or lease from diverse providers, making blocklisting harder.
Protocol also matters. Norton Secure VPN uses OpenVPN and IKEv2 without obfuscation, making it trivial to fingerprint. Speedify uses a proprietary protocol designed for channel bonding (combining Wi-Fi and cellular connections), not obfuscation. These are engineering choices that prioritise different use cases.
If you already subscribe to Norton 360 and the VPN is bundled, it'll work for accessing your home country's content while travelling. It won't reliably bypass Netflix's detection systems. Manage your expectations accordingly.
7. Bottom Line: Infrastructure Scale Beats Protocol Elegance
For streaming in 2026, NordVPN is the correct choice. The 7,700-server fleet makes IP blocklisting a losing game for platforms, NordLynx obfuscates traffic patterns better than standard OpenVPN, and $2.99 per month is competitive. The Panama jurisdiction is weaker than Switzerland or Sweden, but for unblocking iPlayer or Netflix, that's not the threat model.
Runner-up: ProtonVPN if you value Swiss legal protection and don't mind paying 50% more for Secure Core architecture. The 3,000-server count is sufficient for most streaming use cases, and the Stealth Protocol handles deep packet inspection well. If your threat model extends beyond streaming to genuine privacy concerns, Proton's jurisdiction advantage justifies the premium.
Avoid: Mullvad if streaming reliability is your priority. The 600-server count makes it vulnerable to blocklisting, and while the privacy architecture is the strongest in the consumer market, it's overengineered for this use case. Definitely avoid budget providers with fewer than 1,000 servers unless you enjoy troubleshooting connection errors.
