Configure TurboShield on TurboStack

All TurboShield settings for a host. Covers the protection level, rate limits, bot lists, trusted clients and the bot challenge, with the YAML keys for each.

TurboShield is enabled by default with sensible settings. This page describes every setting, so you can adjust it when the defaults do not fit your traffic. For what each mechanism actually does, see What is TurboShield?.

Where to configure it

TurboShield is configured at the host level and applies to every application on that host:

  1. Open the host.
  2. Go to the Security tab.
  3. Find the TurboShield section, then enable it and choose a protection level.

The GUI exposes the settings you need most often. The remaining settings are available in the Source (YAML) view, grouped under the turboshield key.

Basic settings

Key Default Values What it does
turboshield.enabled true true / false Turns TurboShield on for the host. Setting it to false removes the protection completely.
turboshield.level medium low, medium, high, attack The protection level. Tunes all limits at once and unlocks the attack-only mechanisms.
turboshield:
  enabled: true
  level: medium

What each level actually does

The level is a single dial over several limits. Use this table when you need to know what you are changing, rather than guessing between medium and high.

  low medium (default) high attack
Strictly-limited bots 6 req/s 2 req/s 1 req/s 1 req/s
Any single visitor 60 req/s 40 req/s 30 req/s 20 req/s
Burst allowance 800 600 400 250
Simultaneous connections per visitor 160 120 80 60
Excess requests queued, then refused refused immediately refused immediately refused immediately
Distributed-attack detection - - - active
Disguised-browser blocking - - - active
Outdated-browser blocking - - - active
Ban duration standard standard standard longer

Bot lists

TurboShield ships with a curated classification of hundreds of known bots, and merges in a large community-maintained list of known bad bots on top of it. Two lists let you override that classification for individual bots. Each entry is a piece of the bot's name, in lowercase.

Key Effect When to use it
turboshield.allow_bots Never throttled A crawler your business depends on, such as a price-comparison or marketplace feed
turboshield.limit_bots Strictly throttled A crawler that is costing you capacity, such as an AI training or scraping bot
turboshield:
  allow_bots: [channable]
  limit_bots: [bytespider, gptbot]

Both lists are editable in the GUI: Allowed Bots and Extra limited bots, on the host's Security tab, in the TurboShield section under Advanced Settings. Each list is a table of names:

  1. Click Add Allow Bots or Add Limit Bots to add a row.
  2. Type the name, or the part of the name you want to match, and click Save.
  3. Use Edit to change an existing entry and Delete to remove it.

Need a bot treated somewhere between these two, or blocked outright? Ask Support - there are finer gradations available than the two lists above.

Trusted clients

This is the most important list on the page. Addresses on it bypass every TurboShield check, are never rate-limited or challenged, and can never be banned automatically. The same list is also applied at the network firewall.

Key Values What it does
firewall_whitelist List of addresses or ranges Marks sources as fully trusted, across TurboShield and the Firewall
firewall_whitelist:
  - 203.0.113.10        # office
  - 198.51.100.0/24     # partner integration

Use it for:

  • Your own office or virtual private network (VPN), so your team is never affected by protection meant for strangers.

  • Partner and supplier integrations that poll frequently, such as an ERP, PIM or feed exporter.

  • External monitoring and uptime checks, which by nature look like a repetitive bot.

  • Load and security testing you run yourself, which otherwise looks exactly like an attack.

Hosted Power's own monitoring addresses are always trusted automatically, and you do not need to add them.

Bot challenge

The bot challenge asks suspicious visitors to complete an automatic browser check before they reach your site. It is off by default. See what it does.

Key Default Values What it does
turboshield.bot_protection false true / false Turns the bot challenge on. Requires Nginx.
turboshield:
  bot_protection: true

Some clients cannot solve a browser check at all, so whole categories of requests are never challenged: APIs, webhooks, payment callbacks, health checks and the standard endpoints of the common applications are excluded automatically.

The challenge also weighs how a page is being requested. Filtering, searching and sorting are the expensive operations that scrapers abuse, so a request that carries one of those counts as more suspicious. TurboShield already recognises the parameter names the common shop platforms use for this.

When a level does not fit your traffic

Pick a different level first - that is the intended way to change how strict TurboShield is, and it is what almost every environment uses.

If the ladder genuinely does not fit, there are lower-level overrides for the individual rates, bursts and connection limits. They are not documented here because getting them wrong either removes your protection or blocks real visitors. Contact Support with what you are seeing, and they will set the right value for your environment.

Which lists matter most

If you only maintain one thing, maintain the first row.

List Why it matters
firewall_whitelist Prevents your own team, integrations and monitoring from ever being blocked. The single most common cause of a "we are locked out" support ticket.
turboshield.limit_bots Your lever against crawlers that consume capacity without bringing customers.
turboshield.allow_bots Protects the crawlers your revenue depends on, such as marketplace and comparison feeds.
