VPNSecure VPN Protocols Compared

The protocols VPNSecure gives you

VPNSecure has always been an OpenVPN-centric provider. The protocols officially listed on vpnsecure.me are OpenVPN (recommended for security), along with PPTP and an HTTP option for specific cases, while IKEv2 is commonly used on mobile for steady reconnects. All of this runs across gigabit servers in around 48 countries.

• OpenVPN — the core protocol, AES-256 encryption (recommended)
• OpenVPN UDP — for speed
• OpenVPN TCP/443 — for stability and firewall bypass
• IKEv2 — commonly used on mobile
• PPTP — legacy and lightweight, but weak on security

OpenVPN — the recommended default

The heart of VPNSecure is OpenVPN, a long-audited open-source protocol that serves as the industry's security benchmark. VPNSecure runs it with AES-256 encryption, making it a dependable choice for daily browsing, streaming, downloads and anything that needs trust. We suggest setting OpenVPN as your default first, then tuning between UDP and TCP based on the situation.

• Open source and auditable
• AES-256 encryption
• A solid default on every device

OpenVPN UDP vs TCP — what's the difference

VPNSecure offers OpenVPN in two transports. UDP prioritizes speed and low latency, which is ideal for streaming, gaming and general use. TCP prioritizes reliability with guaranteed delivery, which helps on unstable networks or when UDP is blocked. As a rule of thumb, start on UDP; if you see frequent drops or can't connect at all, switch to TCP.

• UDP — fast, low latency
• TCP — stable, guaranteed delivery
• UDP won't connect? Switch to TCP

Getting through firewalls with OpenVPN TCP on port 443

Behind a strict firewall or a corporate network that blocks VPN ports, the most reliable route is OpenVPN over TCP on port 443 — the very port every HTTPS website uses. That makes your VPN traffic blend in with ordinary web browsing, so it usually slips past firewalls and proxies. Note that VPNSecure does not advertise a named obfuscation or "stealth" feature, so we recommend this standard TCP/443 approach rather than relying on a branded mode.

• TCP on port 443
• Looks like normal HTTPS traffic
• Often passes corporate firewalls and proxies

IKEv2 — best when you move between networks

On phones, IKEv2 is a popular pick. Thanks to MOBIKE support it reconnects quickly and stays smooth as you move between Wi-Fi and 4G/5G — great for travel and on-the-go use. If you want maximum cross-device compatibility instead, OpenVPN UDP is also a strong mobile option.

• Fast reconnects when networks change
• Steady while travelling
• Fallback: OpenVPN UDP

Which protocol to choose on VPNSecure

With VPNSecure, make OpenVPN your baseline: use UDP when you want speed, switch to TCP/443 when you need stability or have to pass a firewall, choose IKEv2 for smooth mobile connections, and keep PPTP only for legacy tasks where privacy isn't a concern.

• Everyday use: OpenVPN UDP
• Firewall bypass / stability: OpenVPN TCP/443
• Mobile: IKEv2
• Legacy only: PPTP (not for privacy)
