Security Architecture

Don't Trust Us. Verify.

Our security model is designed so you don't have to trust us. Open protocols, zero-knowledge architecture, transparent practices.

CipherShift is built so you don't have to trust us. Servers run entirely in RAM, so nothing is written to disk and there are no logs to hand over. Encryption keys rotate on a schedule you control and old keys are destroyed. We use open protocols you can inspect and a monthly warrant canary.

Dedicated Server Architecture

Each user gets their own cloud server. No shared infrastructure means no inherited reputation, no IP blacklisting from other users' behavior.

Zero Knowledge Design

We cannot see your traffic. All encryption happens on your device. Your dedicated server processes encrypted traffic, we never see plaintext.

No Logs Infrastructure

We don't log connection timestamps, IP addresses, bandwidth usage or traffic data. We can't hand over what we don't have.

RAM-Only Servers

All servers run entirely in temporary memory, so nothing is saved to disk. If anyone seizes the server, a reboot wipes everything. No logs to recover because they never existed.

Signature Feature

CipherShift Key Rotation

Most VPNs generate keys once and use them for months. With CipherShift you rotate keys with one tap any time, and Pro adds automatic rotation on a 12, 24, 48 or 72 hour schedule. Old keys are deleted, not archived.

How It Works

1

Connection

New session keys generated

2

Rotation

Timer triggers key refresh

3

Destruction

Old keys wiped from memory

4

Continuity

No reconnection needed

One tap

On-Demand Rotation

Rotate your keys any time from the app. Old keys are deleted, so a key compromised today does not unlock yesterday's traffic.

Scheduled

Auto Rotation (Pro)

Pro plans rotate keys automatically on a schedule you choose: every 12, 24, 48 or 72 hours. Set it once and forget it.

Seamless

No Reconnection

Rotation updates your tunnel in place, so your connection keeps running. No dropped sessions while keys refresh.

Pro Feature

Ghost Mode

Using the VLESS + REALITY protocol, Ghost Mode makes your traffic look like a normal HTTPS connection to a legitimate website, so it is much harder for deep packet inspection to flag.

Designed for: Hostile network environments where standard VPN protocols are quickly detected and blocked.

Protocols & Encryption

Industry-leading protocols, properly implemented.

WireGuard

Use at home or on trusted networks. Reconnects instantly and uses minimal battery. Just 4,000 lines of code (vs 400,000 for OpenVPN) means fewer places for bugs.

Default

Shadowsocks

Use when WireGuard gets blocked. Disguises VPN traffic as normal internet use. Gets through basic network filters that try to detect and block VPN connections.

Included

VLESS + REALITY

Use on hostile networks. Ghost Mode makes your connection look like normal HTTPS traffic to real websites. For aggressive censorship environments where other protocols fail.

Infrastructure Security

How we protect your dedicated server.

Multi-Cloud, Multi-Jurisdiction

Servers distributed across multiple independent cloud providers in privacy-respecting jurisdictions. No single point of failure. No single provider has the full picture. As they say in Spies Like Us: "We're not in this together... that's the whole point."

Isolated Instances

Each user's server is a separate VM instance. No shared processes, no shared memory, no risk of cross-contamination.

Locked-Down Management

Management access is key-based only, never passwords. Every server is provisioned automatically, so there is no standing human access to your traffic.

Ephemeral by Design

Config, keys and logs live in RAM-backed storage, never written to the disk. Power off the server and that data is gone, by design.

Transparency

We show our work because “trust us” isn't good enough.

Warrant Canary

Cryptographically signed and updated monthly. If we receive a government order we cannot disclose, the canary will not be updated.

Verifiable by Design

You don't have to take our word for it. RAM-only servers write nothing to disk, so there are no logs to produce. We use open protocols you can inspect, and the warrant canary is signed every month.
