A RAM-only VPN with nothing on disk
A RAM-only VPN runs its servers entirely in memory instead of on hard drives. Nothing is written to disk, so when a server is switched off or taken away, its keys, settings and connection records are gone. Every Secria VPN server keeps its keys, settings and connection state in memory only, with post-quantum encryption on top.
What RAM-only means
Diskless servers, explained
Memory, not a hard drive
A normal server stores its system and files on a disk that keeps them after a restart. A RAM-only, or diskless, server loads everything into memory, which empties the moment power is cut.
Nothing piles up
Keys, settings and connection records are gone after every restart. Nothing left over from last month, or last year, is sitting on a drive.
Nothing to hand over
If a server is seized or unplugged, there is no drive holding keys, configs or connection records to copy later.
Not the same as no logs
RAM-only is about where data could live. A no-logs policy is about what is recorded at all. You want both, and it helps to know why free VPNs often have neither.
RAM-only vs encrypted disks
Two ways to protect a VPN server
Some providers encrypt their server disks instead of going diskless. The difference is what is left behind.
| Question | Full-disk encryption | RAM-only (Secria VPN) |
|---|---|---|
| Keys, configs and connection state | Written to disk, encrypted.1 | Held in memory only, never on disk. |
| After power off | Encrypted data stays on the disk. | Gone. Memory empties. |
| Keys for that data | Kept by the provider off-site.1 | No stored data to unlock. WireGuard keys live only in kernel memory. |
| After a restart | The disk comes back with what was on it. | Keys, configs and connection state are gone. |

Inside Secria VPN
What lives in memory, and for how long
Server keys
WireGuard private keys exist only in kernel memory. They are never written to a disk.
Your session key
The post-quantum preshared key for your connection is made fresh when you connect and lives in RAM only for that connection.
Session record
We do not record browsing, DNS queries or traffic contents. While a session is live we hold the account and device it belongs to, the server in use and the time it started. That record goes when the session ends.
Multi-hop circuits
When you route through three servers, the circuit is tracked only in server memory with a short time-to-live.
Every server runs the same RAM-only setup and the same post-quantum tunnel. There is no cheaper tier of server to be routed onto. Details are in our VPN whitepaper.
Before you pick one
How to check a VPN's RAM-only claim
Is it every server?
Look for “all servers”, not “our new servers” or one region. A partial rollout means your connection may land on a disk-based one.
What is kept while you're connected?
RAM-only covers what survives a reboot. Ask what the provider holds during a live session, and when it is deleted. We spell ours out word for word.
Is it written down?
A technical document that names what lives in memory, like keys, configs and session state, says more than a feature badge.

Questions about RAM-only VPNs
What is a RAM-only VPN server?+
A VPN server that runs entirely in memory instead of from a hard drive. Nothing is written to disk, so switching it off wipes everything it held.
What does diskless VPN mean?+
It is another name for a RAM-only VPN. The servers have no drive storing the system or data, so there is nothing to recover after a shutdown or seizure.
Is RAM-only better than full-disk encryption?+
They solve the same problem differently. Full-disk encryption keeps data on the disk and relies on the keys staying safe. RAM-only never writes the data in the first place, so there is nothing left to unlock.
Does a RAM-only VPN mean no logs?+
Not by itself. RAM-only decides where data can live. A no-logs policy decides what is recorded at all. Secria VPN keeps no activity logs: we do not record browsing, DNS queries or traffic contents. While a session is live we hold the account and device it belongs to, the server in use and the time it started. That record goes when the session ends.
Are all Secria VPN servers RAM-only?+
Yes. Every server runs the same RAM-only setup and the same post-quantum tunnel.
Nothing on disk. Nothing to hand over. RAM-only servers and post-quantum encryption, on by default.
