Lately, remote work has surged, and remote access tools have become more widespread in parallel. So, what should we say about the security vulnerabilities of these tools? Which protocols/technologies do you think hold up better? We can even dive into technical details—I'm up for some deep thinking.
How safe are remote access tools?

One of the most robust protocols for remote‑access tools is **WireGuard**—I’ve been using it in my recent projects too. The setup is simple, performance is high, it’s open‑source, and incredibly lightweight. After big attacks like WannaCry, nobody is thinking about old, heavyweight protocols like SSL/PPTP anymore. WireGuard’s biggest advantage is that it uses modern encryption standards like AES‑256 and ChaCha20. Plus, because it’s UDP‑based, it works smoothly even behind NAT, which is a huge help when you’re working from home.
I think we should also move to a **Zero Trust** architecture—so instead of “trust‑based,” we adopt a continuously‑verified approach and stop automatically trusting any device. For example, there are free and simple Zero Trust VPN solutions like **Tailscale**, which use the WireGuard stack. You can have it set up in about five minutes. Unlike old‑school VPNs that constantly “can’t connect,” there were no issues even on mobile. This way, not only users but the devices themselves are constantly authenticated.
