Fraudulent disputes are brutal—especially for small providers, like myself.

A single “test” payment or low-value order can turn into a chargeback that wipes out the revenue and slaps you with an extra fee. My PSA: **turn on Stripe Radar and tune it for our kind of business ** so you’re not paying real money for €1.50 card tests.

What Radar does: Stripe scores every payment for risk (0–99) and can automatically block, review, or step-up authenticate (3D Secure) the sketchy ones. Defaults are sensible, but a few tweaks make a big difference for hosts and other small shops.
Three quick tips:

• Use the default thresholds (block ≈ 75, review ≈ 65) as a baseline, then tighten if you’re seeing card tests or “low-amount” fraud spikes.
• Ask for 3D Secure on higher-risk payments (for example: new customers, high amounts, IP/card country mismatch). 3DS can shift fraud liability to the issuer when the authentication succeeds.
• Lean on allow/block lists for repeat good customers and known abusers (emails, IPs, BINs). It’s fast and reduces false positives.

About dispute fees: if a dispute lands, Stripe debits the payment amount plus a dispute fee (and sometimes an additional counter-dispute fee). Exact amounts depend on region, so check your local pricing. Prevention really does pay.
If anyone wants a starter set of Radar rules tailored to low-ticket hosting, I’ve put some examples below, use them for your safety!

1. Quick “turn this on” checklist (Stripe Dashboard)

• Risk thresholds: keep the default block/review thresholds to start; backtest before tightening.
• 3D Secure: enable/request 3DS dynamically for elevated-risk scenarios (you can do this with Radar rules.
• Analytics/Insights: check Radar Analytics to see top fraud drivers and tune rules from real data.

2. Copy-paste Radar rule ideas

Keep in mind these are examples, test and adjust the rules to your liking.

1. High-risk payments
   Block if :risk_level: = 'highest'
   Review if :risk_level: = 'elevated'

(Use these with your thresholds so ML + rules work together.)

2. Country/IP mismatch (common with card testing)
   Block if :card_country: != :ip_country:

3. Step-up auth for suspicious combos
   Request 3DS if :risk_level: = 'elevated'
   Request 3DS if :is_anonymous_ip: OR :is_proxy:

(Use request-3DS rules before block/review rules; that’s the evaluation order.)

4. Velocity limits (burst attempts)
   Block if :authorized_charges_per_ip_address_hourly: > 3
   Block if :authorized_charges_per_card_number_hourly: > 3

(Adjust thresholds based on your pattern; Stripe calls these “velocity” attributes.)

That’s it from me. Turn on Radar, tune a couple rules, and keep your margins yours. Got questions? Feel free to ask.

Why Cloud Hosting’s Tough on Small Providers
It’s Complicated: Jumping into cloud hosting means learning new tech—hard when you’re a small team.

It’s a Commodity: Cheap cloud plans make it tricky to show why your niche service is worth it.

More Rivals: Fewer customers for traditional hosting means everyone’s fighting for the same slice.

How to Compete (and Stay Fraud-Free)
A few strategies small hosts can use to grab attention and keep operations secure:

Make Simple Videos: People love quick tutorials. Shorts on DDoS protection setup, and it cut support tickets by 10%.

Use Social Media Smartly: Answer hosting questions on platforms like Twitter or forums like this one. Link back to a secure site (with MFA-enabled forms) to build trust.

Automate the Right Way: Switch to a PCI-DSS-compliant automation tool with 2FA, which saved us 5 hours a week and blocked fake signups.
