Frequently Asked Questions

What Happens When You Connect to a VPN: Step by Step

When you click "Connect" in a VPN app, a complex sequence of operations happens in under a second. Here's exactly what occurs, explained without jargon:

1. Authentication: Your VPN app sends your credentials to the VPN server. The server verifies you are a legitimate subscriber. This exchange itself is encrypted to prevent credential interception.
2. Key exchange: Your device and the VPN server negotiate encryption keys using a process called a handshake (TLS or Noise Protocol, depending on the VPN protocol). These keys are unique to your session and are mathematically impossible to guess — even with significant computing resources.
3. Tunnel establishment: A virtual "tunnel" is created between your device and the VPN server. All your internet traffic is now routed through this tunnel rather than directly to destinations.
4. Encryption: Every packet of data leaving your device is encrypted before it enters the tunnel. When it reaches the VPN server, it's decrypted, then forwarded to its actual destination (the website or service you're connecting to).
5. IP masking: From the destination server's perspective, the traffic is coming from the VPN server's IP address — not yours. Your real IP is invisible to any external observer.
6. Return path: Response data from the destination travels to the VPN server, gets encrypted, sent back through the tunnel to your device, and decrypted for your use.

VPN Encryption Explained: What AES-256 Actually Means

Most premium VPNs advertise "AES-256 encryption." Here's what that actually means and why it matters:

AES (Advanced Encryption Standard) is a symmetric cipher — meaning the same key is used to both encrypt and decrypt data. It was established by NIST in 2001 and is used by the US government, military, and banks globally. There's no known theoretical attack that can break AES — brute-forcing a 256-bit key would take longer than the age of the universe with all current computing power on Earth combined.

256-bit refers to the key length. AES comes in 128-bit and 256-bit variants. While 128-bit is already unbreakable with current technology, 256-bit provides additional margin against future developments in quantum computing. Most VPNs use AES-256-GCM (Galois/Counter Mode), which adds authentication to the encryption — ensuring data hasn't been tampered with during transit.

WireGuard uses ChaCha20-Poly1305 instead of AES. This is a different cipher that's equally secure but significantly faster to process, especially on mobile devices without hardware AES acceleration. WireGuard's encryption is why it achieves dramatically faster speeds than OpenVPN with AES.

The 4 VPN Protocols Explained

WireGuard — The Modern Standard (2026)

WireGuard is the newest major VPN protocol, first released in 2019 and now the recommended choice for almost all use cases in 2026. It uses only 4,000 lines of code (compared to OpenVPN's 70,000+), making it simpler to audit, easier to maintain, and significantly faster. WireGuard uses state-of-the-art cryptographic primitives (ChaCha20, Poly1305, Curve25519) and achieves throughput that often exceeds 900 Mbps on modern hardware. Its primary limitation is that it doesn't inherently obfuscate traffic — VPN-aware deep packet inspection can identify WireGuard connections, which is why obfuscated servers use other approaches.

OpenVPN — The Established Standard

OpenVPN has been the gold standard for VPN security since 2002. It uses TLS (the same technology that secures HTTPS websites) for its handshake and can run over both UDP (faster, less reliable) and TCP (slower, more reliable through firewalls). OpenVPN is slower than WireGuard but extremely well-audited and compatible with a vast range of hardware and software. On a router or older device, OpenVPN may be the only available protocol — expect speeds of 50–200 Mbps. For high-throughput or gaming use cases, switch to WireGuard if available.

IKEv2/IPSec — Best for Mobile

IKEv2 (Internet Key Exchange version 2) paired with IPSec is built into most modern operating systems — iOS, macOS, Windows, and Android all support it natively. Its killer feature is MOBIKE: it maintains the VPN connection when you switch networks (e.g., switching from Wi-Fi to cellular data), without re-authentication. This makes it the historically preferred protocol for mobile users. WireGuard has largely replaced IKEv2 for most mobile use cases in 2026, but IKEv2 remains useful for manual VPN configurations using the built-in OS client.

Proprietary Protocols: NordLynx, Lightway, Catapult Hydra

Major VPN providers have developed proprietary protocols optimized for their specific infrastructure. NordLynx (NordVPN) builds a double NAT system on top of WireGuard that addresses WireGuard's privacy concerns around IP logging while maintaining its speed. Lightway (ExpressVPN) is built on wolfSSL and achieves sub-second connection times with performance comparable to WireGuard. Catapult Hydra (Hotspot Shield) uses a UDP-based protocol optimized for high-latency connections. These proprietary protocols are generally only available through the provider's official apps.

What a VPN Protects — and What It Doesn't

Understanding the scope of VPN protection prevents both over-reliance and under-reliance on the technology:

✅ What a VPN Protects

• Your IP address from websites, services, and any server you connect to. They see the VPN server's IP, not yours.
• Your traffic from your ISP. Your ISP can see you're connected to a VPN server but cannot see what sites you visit or what data you transmit.
• Your data on public Wi-Fi. A VPN prevents malicious actors on the same network (cafe, airport, hotel) from intercepting your unencrypted traffic via a man-in-the-middle attack.
• DNS queries. A good VPN routes all DNS through its own servers, preventing your ISP from seeing which domains you look up.
• Traffic correlation from network-level observers. Your ISP, network admin, or government network monitors cannot see what you're doing, only that you're using a VPN.

❌ What a VPN Does NOT Protect Against

• Cookies and browser fingerprinting. If you log into Google or Facebook while on a VPN, those services know it's you — they have your account credentials regardless of your IP. Cookies tracking across sites are not affected by VPN use.
• Malware already on your device. A VPN encrypts traffic between your device and the VPN server, but if malware on your device is sending data before it enters the VPN tunnel, that data is not protected.
• Account-level tracking. If you're logged into services, they can track your behavior at the account level regardless of IP changes.
• A malicious or logging VPN provider. If the VPN itself keeps logs of your activity, it can hand those to law enforcement or sell them. This is why no-logs policies and independent audits are essential.
• WebRTC and browser-level IP leaks if not properly addressed. Some browsers can reveal your real IP through WebRTC even with a VPN active — use a VPN with WebRTC leak protection or configure your browser to disable WebRTC.

VPN vs Proxy vs Tor: What's the Difference?

For everyday privacy needs, a VPN is the right tool. For situations where anonymity is critical and speed doesn't matter (accessing sensitive information in high-risk environments), Tor provides stronger anonymity guarantees. Proxies are useful only for specific, low-security geo-bypass use cases — they provide no privacy protection.
