Features that matter
in hostile networks
Every design decision in ZoltVPN starts with one question:
will this work when the firewall is actively trying to stop it?
AI that makes your VPN invisible to Deep Packet Inspection
Deep Packet Inspection (DPI) is the technology firewalls use to identify what protocol your traffic is running — even when it's encrypted. WireGuard has a distinctive protocol signature. OpenVPN produces a recognizable byte pattern. Both can be identified and blocked in milliseconds.
CyberPort AI is different. Its neural packet engine deconstructs your data stream and reconstructs it at the binary level — rewriting byte distributions, packet timing intervals, and flow structure so no DPI classifier can match it to any known protocol signature. The firewall sees structurally random encrypted data with no classifiable pattern. There is no VPN signature to detect, because CyberPort AI eliminates it before any packet leaves your device.

from normal HTTPS.
Near-zero speed overhead
Most VPN protocols add a second encryption layer on top of already-encrypted traffic. CyberPort AI avoids this overhead — its AI engine analyzes the entropy profile of each stream and applies only the recomposition transforms needed, skipping redundant processing with no quality loss.
The result is benchmark speeds that other protocols can't match. At 1 Gbps line speed, you lose less than 1% to protocol overhead. OpenVPN users typically lose 15–20%.
Our servers have exceeded 2 Gbps in our own speed tests, and users in China who compared ZoltVPN side by side with the leading VPN services found it 30–40% faster.
Throughput at 1 Gbps line speed
Tested on identical hardware, same route, average of 100 runs.
Works in the places that block everything else
The rule is simple: if HTTPS on port 443 works, ZoltVPN works. Because to the network, it is HTTPS.
- China (GFW) — The Great Firewall uses sophisticated DPI. WireGuard and OpenVPN are blocked within minutes of a new IP being provisioned. CyberPort AI passes.
- Russia — Russian networks detect and block the methods most VPNs use, and many VPN apps have been removed from app stores. CyberPort AI switches to a connection model that still works.
- Iran — National internet filtering actively blocks VPN protocols. CyberPort AI traffic looks like regular browsing.
- Corporate firewalls — Most enterprise proxies block UDP outright (killing WireGuard). ZoltVPN runs over TCP 443 and looks like business web traffic.
- University networks — Typically block VPN protocols by DPI. CyberPort AI produces traffic with no classifiable protocol structure, passing inspection undetected.
- Hotel / airport Wi-Fi — Captive portals and restricted guest networks that allow only web traffic.
Global server network
100+ servers on Microsoft Azure, Amazon Web Services and Google Cloud, in every region that needs them. Multiple nodes per location for redundancy — if one IP gets blocked, traffic fails over automatically. Need a fixed address? We also provide dedicated static IPs, residential or cloud — see business services.
No logs. Not "minimal logs." None.
We don't store connection logs, timestamps, IP addresses, DNS queries, traffic volume, or browsing history. Our servers are configured to write nothing to disk about your sessions.
If we receive a legal request, there is nothing to produce. We cannot reveal what we do not have.
- No connection timestamps
- No source IP addresses logged
- No DNS query history
- No bandwidth or traffic logs
- No session duration records
One tap. You're in.
The complexity lives in the protocol, not the UI. ZoltVPN's desktop apps for macOS and Windows reduce a technically sophisticated connection process to a single button.
- macOS — native menu bar app
- Windows — system tray integration
- Auto-select fastest server
- Kill switch — cuts traffic if VPN drops
- Auto-connect on untrusted networks
How CyberPort AI handles your security
CyberPort AI is not just a protocol name — it's an active intelligence layer that runs on every ZoltVPN connection. Here is what it does in real time:
- Threat pattern learning — CyberPort AI continuously ingests firewall blocking signals from our global server fleet and retrains its packet recomposition model automatically. When a new detection pattern is found anywhere on the network, every user's traffic structure adapts within minutes.
- Entropy normalization — The AI analyzes packet timing, size distribution, and byte-level entropy and normalizes your traffic to match the statistical profile of ambient internet traffic — indistinguishable from ordinary encrypted web data, not a VPN tunnel.
- Intelligent server routing — CyberPort AI scores every available exit node by latency, block risk, and load — and silently re-routes your connection if a server's block risk score rises above threshold.
- Binary-level packet recomposition — The AI continuously varies packet framing, header structure, and byte sequences across connections so no two sessions share the same measurable traffic signature.
- Adaptive overhead elimination — The AI profiles each data stream in real time and strips redundant processing transforms on the fly, maximizing throughput without compromising the recomposition integrity.
