Servury Blackbox zero-knowledge VPS - Encrypted RAM, Encrypted disk and no guest agent - from 9.99$

servuryservury Hosting Provider
in VPS

I'm Matteo, I run Servury, a 100% anonymous VPS/VDS provider platform. Today, I'm thrilled to present to you our new product - Blackbox, which I believe is the first of it's kind. It's a zero knowledge VPS, where even we (the hypervisor) can't read your VM's memory, disk, or run arbitrary commands inside of it.

Every hosting provider on this forum can do three things to your VPS. They can dump your RAM from the hypervisor. They can execute commands inside your guest without your SSH key. And they can read your disk by mounting it from the host. That is not a knock on anyone - it is simply how virtualisation works, and every provider here, including the big ones, sits in that position whether they want to or not.

This is a box where we can't do any of the three. Not "we promise not to" or "we have a policy". The capability is removed, and you can verify all of it from inside your own VM.

We are not the cheapest box on this forum and we're not trying to be. If you want 4 GB for $20/year, that offer exists and it isn't this one. What you're paying for is a machine its operator cannot look inside.


The three things, and how you check them yourself

1. We can't read your memory

AMD SEV-SNP. Your guest's RAM is encrypted with a key that lives in the CPU's security processor.

$ dmesg | grep -i "Memory Encryption"
Memory Encryption Features active: AMD SEV SEV-ES SEV-SNP

$ dmesg | grep VMPL
SEV: SNP running at VMPL0.

And you don't have to take that output on faith either, because the attestation device is exposed to you:

$ ls -l /dev/sev-guest
crw------- 1 root root 10, 262 /dev/sev-guest

That is the interface to the AMD PSP. You can pull a signed attestation report from the silicon and check it against AMD's root of trust yourself. We cannot forge it and we cannot intercept it.

2. We can't reach into your guest

Nearly every VPS you have ever rented runs a guest agent - a daemon inside your VM listening on a virtio serial port, which lets the host run commands as root inside your guest, read arbitrary files, and reset your password. It is how "reset root password" works in a control panel. It is enabled by default in Proxmox, and both Azure and GCP keep their agents running inside confidential VMs too.

On a Servury Blackbox there is no agent, and no port for one. It isn't disabled in software where it could be switched back on - the virtio-serial device is absent from the QEMU command line entirely. From inside your VM:

$ ls /dev/virtio-ports/ 2>/dev/null
(nothing - there is no org.qemu.guest_agent.0)

Because the channel does not exist, "reset my root password from the panel" is a feature we genuinely cannot offer you on a Blackbox VM. If we have the ability to reset your root password, you're forced to trust we won't tamper with your VM at any given time, which is utter garbage in our opinion. Don't trust, verify.

3. We can't read your disk

Optional LUKS full-disk encryption, unlocked over SSH by dropbear in the initramfs. You set the passphrase yourself on first boot and it never touches our systems. Combined with the above: your disk is ciphertext at rest, your RAM is ciphertext in use, and the key exists only in encrypted memory we can't read.

And we don't know who you are

No email, no phone, no KYC. Signup hands you a credential and that is the whole account. Payment is 11 coins through our own processor - our node, our watcher, no third party in the middle collecting your addresses and your IP - or Stripe, or cash by mail.

Zero logs. No access logs anywhere on the platform, including the looking glass below. This is the only thing you can't really verify. See Trusting Trust (Ken Thompson, 1984). We'll be looking into getting an audit done in the future.

No-JS Compatible. Servury is designed to work with JS disabled. For people who pay with credit cards, we only load the Stripe assets when credit card is explicitely selected as a payment method.

Kickass features

We own the whole stack. AS395904, 23.155.44.0/24, 2602:f41c::/36, our own switch, our
own hardware at Cologix MTL2. If you traceroute the looking glass you are looking at the same path your VM sits behind, because it is literally an address out of the same /24 your VM gets assigned from.

BYOIP Bring your own prefix and we announce it from AS395904, v4 and v6, as buttons in the panel rather than a ticket. RPKI verification is automated.

rDNS you set yourself, in the panel, not by ticket.

12 OS templates, all UEFI, all built by hand: Debian 12/13, Ubuntu 24.04/26.04, Rocky 9, AlmaLinux 9/10, FreeBSD 14/15, OpenBSD 7.8/7.9, Windows Server 2025.

Manual abuse report handling, on the Pro tier.

Priority human support, from me, the founder. On the pro tier you get my cellphone number.


Plans

Both plans are on the Montreal node (Cologix MTL2). Every plan: 1 dedicated IPv4 + a routed /64 IPv6, 10 Gbps unmetered, NVMe on a ZFS mirror, full root, KVM.

Plan vCPU RAM Disk Price
Blackbox Core 1 512 MB 50 GB NVMe $9.99/mo
Blackbox Pro 2 4 GB 50 GB NVMe $39.99/mo | -> manual abuse report handling & priority phone support

Order: https://servury.com

Need something bigger? The nodes are 32c/64t EPYC with 250 GB of RAM and 7 TB of NVMe, so there is a lot of room above the Pro plan. I'll build a custom spec - more cores, more RAM, a big volume, whatever you actually need - on 6 months prepaid. Tell me the spec and I'll quote it in the thread so everyone can see the number.


Looking glass, test IPs, test files

https://mtl-lg.servury.com

  • Looking glass IPv4: 23.155.44.21
  • Looking glass IPv6: 2602:f41c:0:a::1
  • Test files: 100 MB / 1 GB / 10 GB
  • iperf3: iperf3 -c mtl-lg.servury.com -p 5201 -P 4 (add -R for the other direction)

The looking glass keeps no access log and records no visitor IP addresses - same as the rest of the platform. It also serves Bootstrap from our own host rather than a CDN, so opening it doesn't hand your address to a third party either.
