When you pick a VPN, you are really picking a protocol. It is not some secondary setting "for geeks" — the protocol decides the most important thing: whether the VPN will work at all. Speed, stability on mobile networks and, most crucial in the era of blocking, whether the connection can slip past your provider's filters. The very same server flies on one protocol and refuses to connect for a single second on another.
Let's break down the three protocols people argue about most today — OpenVPN, WireGuard and VLESS — honestly, without the marketing. Each has a genuine strength, and there is no "best for everything": there is only the right one for the job.
OpenVPN appeared back in 2001 and has since become an industry standard. It is flexible: it runs over UDP and TCP, can travel over port 443, supports a wide range of encryption options and has been battle-tested for years in corporate environments.
Strengths:
It has one weak spot, but a serious one. OpenVPN has a recognizable "fingerprint": deep packet inspection (DPI) systems have learned to detect its handshake even on port 443. That is why in countries and networks with active blocking, OpenVPN is often the first to be cut — the connection either fails to establish or drops after a few seconds.
Where it fits: corporate access to a work network, connecting to a home server, countries and providers without aggressive DPI. If your old VPN stopped working, it was almost certainly running OpenVPN or a similar protocol.
WireGuard is a young protocol that rewrote the rules on speed. Its codebase is hundreds of times smaller than OpenVPN's, it runs in the system kernel and uses modern cryptography. In practice that means fast connects, excellent throughput and instant recovery when you switch from Wi-Fi to mobile data.
Strengths:
The same vulnerability as OpenVPN — but in its own way. WireGuard in its "raw" form is also spotted by DPI: it has characteristic packets and works over UDP, which filters can identify and choke. It was never built for disguise — its goal was speed and simplicity, not invisibility. To work under blocking, WireGuard needs to be hidden under a layer of obfuscation.
Where it fits: when you need maximum speed — streaming, gaming, downloads — and the network is not blocking you. An excellent choice for everyday use where there is no hard censorship.
VLESS is a modern protocol from the Xray family, and its goal is fundamentally different. It does not try to be just a "fast tunnel" — it tries to look no different from ordinary traffic. Paired with Reality/XTLS, the connection looks like an everyday visit to a real, major website over HTTPS. To DPI it is not a "suspicious VPN" but ordinary encrypted web traffic — and blocking that without breaking half the internet is very hard.
Strengths:
Honest about the downsides: VLESS is harder to configure by hand, and on a calm network its speed edge over WireGuard is not always noticeable. Its strength shows precisely where the fight against blocking is happening.
Where it fits: getting around blocks and DPI, reaching restricted sites and services, unstable and "filtering" networks. BessyConnect runs on exactly this — VLESS + Reality.
If we drop the emotion and speak plainly:
None of them is "bad". WireGuard is optimized for speed, OpenVPN for flexibility and compatibility, and VLESS for invisibility to filters. In 2026, when blocking has grown smarter, that last point is usually what decides whether a site opens at all.
All of the above is worth understanding, but you absolutely do not have to configure it yourself. Keys, certificates, obfuscation, transport choices — these are easy to get wrong and can eat an entire evening.
In BessyConnect the choice is already made for you: the service runs on VLESS + Reality, the most block-resistant option, and everything is set up out of the box. There is nothing to configure — install the app, sign in with Apple, Google or email, pick a country and connect. More than 100 servers in 15 countries, unlimited traffic, no browsing logs kept. One account works on all your devices at once, and you switch server inside the app in a couple of seconds.
BessyConnect apps:
On a calm network without blocking, WireGuard is usually the fastest. But a "fast" protocol is useless if your provider cuts it: then the real speed comes from the one that actually gets through — VLESS + Reality.
All three use strong modern encryption, and on cryptography there is no loser among them. The difference is not about being "cracked" but about visibility: OpenVPN and WireGuard are easier to detect, while VLESS + Reality is harder to spot because it disguises itself as ordinary HTTPS.
Most likely your provider started applying DPI and recognized OpenVPN's "fingerprint". The protocol itself did not break — it simply became detectable and blockable. The fix is to move to a protocol that does not stand out in traffic, such as VLESS + Reality.
No. Knowing the difference is useful, but you do not have to configure anything: in BessyConnect it already runs on VLESS + Reality.
If you want a protocol that does not give itself away, without the manual fuss of keys and configs, choose BessyConnect. It is built from the ground up on VLESS + Reality: the connection looks like ordinary HTTPS, so it works where familiar VPNs have already given up.
