The cheapest VPS to host Security Onion, by its own requirements

Security Onion is a network security monitoring and threat hunting platform. At its minimum spec (4 vCPU, 24 GB RAM, 200 GB disk), the cheapest plan we track is Contabo Cloud VPS 8 at $16.80 a month (ex VAT), and 16 providers have a plan that fits.

What Security Onion's documentation asks for

Minimum: 4 vCPU, 24 GB RAM, 200 GB disk
Recommended: not stated

From the documentation: In a standalone deployment, the manager components and the sensor components all run on a single box so your hardware requirements will reflect that. You’ll need at minimum 24GB RAM, 4 CPU cores, and 200GB storage.

Source: Security Onion documentation, read 2026-10-11.

A standalone deployment runs the manager and sensor components on one box; the docs suggest more memory if you monitor even a small amount of network traffic.

One row per provider: its cheapest unmanaged plan with at least 4 vCPU, 24 GB RAM, 200 GB disk. Ranked on the real monthly cost, including a separately billed IPv4 address where that applies.

All figures are the providers' own published list prices in USD, on-demand monthly. The index was last refreshed 2026-10-14, and every row shows the date its own price was read. Nothing here is live or negotiated pricing. Where a provider bills a public IPv4 address on top, it is added to the monthly price, the ranking and every cost per vCPU or per GB, and the row shows the parts: the server, any disk priced apart, and the IPv4 charge. Some prices exclude VAT or need a commitment; the plan notes say which. Check the provider's pricing page before you commit.
