FAQ

Everything you need to know

about the product and billing.

  • Are there any usage limits or quotas?

    Each plan includes fixed allowances: Core: 2 protected root domains (unlimited subdomains), 1 TB of traffic, 50M requests per month, 10 rate limit rules, 7-day log retention. Advanced: 5 protected root domains (unlimited subdomains), 5 TB of traffic, 100M requests per month, 50 rate limit rules, 20 custom global filters, 10 custom content filter rules, 14-day log retention. If your requirements go beyond these allowances, our sales team will scope the right setup with you: email sales@link11.com or arrange a callback via our contact form.

  • What support do I get?

    Your plan starts with a complimentary onboarding call: a Link11 engineer helps you go live, included once in every Core and Advanced plan. After that, our support team assists you via ticket and email, directly from your Link11 account, the same way for both plans. If you ever need more, for example phone support or a personal contact, our sales team will create an individual offer for you: email sales@link11.com or arrange a callback via our contact form.

  • How does the money-back guarantee work?

    All Core and Advanced plans purchased on or after January 1, 2026 include a 90-day money-back guarantee, based on the conditions valid at the time of purchase. Use Link11 in your own environment for up to 90 days. If you’re not satisfied, cancel within this period and you’ll receive a full refund of your subscription fee: once per customer, via your original payment method, no justification required. To request your refund, email finance.de@link11.com.

  • Is there a free trial?

    The 90-day money-back guarantee is your test phase: you evaluate Link11 with real traffic in your real environment, and if you’re not convinced, you’ll get your subscription fee back in full.

  • Can I cancel my subscription at any time?

    Yes. Monthly plans can be cancelled to the end of the current billing month. Annual plans can be cancelled up to one month before renewal (the renewal date is your purchase date). Cancel in writing by emailing finance.de@link11.com; you’ll receive written confirmation with the effective date.

  • Can I change my plan later?

    Yes. Upgrades take effect immediately: open a ticket in your Link11 account. Downgrades follow the same notice periods as cancellations. For requirements beyond Core and Advanced, our sales team will scope the right setup with you: email sales@link11.com or arrange a callback via our contact form.

  • Can I use multiple domains or users?

    Yes. Core protects 2 root domains and Advanced protects 5. Subdomains are always unlimited, and multiple user accounts are included in every plan. To protect more domains, our sales team will scope a setup that fits: email sales@link11.com or arrange a callback via our contact form.

  • How is billing handled (monthly or annually)?

    You can choose between monthly and annual billing. Monthly customers receive an initial pro-rata invoice up to the end of the current month, followed by full calendar-month invoices. Annual customers are billed upfront for the full twelve months and save 20%.

  • What payment methods are supported?

    Self-service plans are paid by credit card. Enterprise agreements can also be settled by wire transfer, and our finance team supports custom invoicing and procurement processes.

  • Where is my data stored?

    By default, your data is stored in Europe. If you prefer a specific region, our support team will move your setup to Germany only, North America, or Asia Pacific: simply open a ticket in your Link11 account or email support@link11.com.

  • How is my data secured?

    Link11 follows strict security protocols to protect your data at rest and in transit. This includes end-to-end encryption, access control, network segmentation, and continuous monitoring. Our infrastructure is hardened and operated in accordance with global best practices and compliance requirements.

  • Is this suitable for small businesses or large enterprises?

    Core and Advanced are self-service plans for teams that set up protection themselves, live in about 30 minutes. Enterprise is our managed plan for organizations with compliance, SLA, or integration requirements. Not sure which fits? Email sales@link11.com or arrange a callback via our contact form.

  • Which documents govern my contract?

    Self-service plans are governed by the Terms of Service, the Data Processing Agreement, and the Money-Back Guarantee Terms.

  • Your question isn’t answered here?

    No problem at all. Whether something is still unclear or your requirements go beyond Core and Advanced: talk to us. Our sales team will find the answer with you and, if you need it, create an offer that fits exactly. Email sales@link11.com or arrange a callback via our contact form. We look forward to hearing from you.
