The short version

  • Each has a real cost: Adyen there is a minimum monthly invoice, set by industry and business model and only disclosed through the sales team, so small volumes are not economic; Qualys VMDR licensing is per asset and each capability is its own subscription, so patch management, endpoint detection, web application scanning, container security and policy compliance are separate line items, and the platform demonstrated in a proof of concept is rarely the platform in the quote.
  • They diverge on capability: Adyen covers Payment processing, Qualys VMDR covers Cloud Agent.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Adyen

  • There is a minimum monthly invoice, set by industry and business model and only disclosed through the sales team, so small volumes are not economic
  • Published fees are indicative rather than a rate card, with real pricing negotiated
  • Interchange++ means the card cost varies per transaction rather than being a single predictable percentage
  • Alternative payment methods carry their own rates on top, such as 3.3 percent plus $0.10 for American Express in North America

Qualys VMDR

  • Licensing is per asset and each capability is its own subscription, so patch management, endpoint detection, web application scanning, container security and policy compliance are separate line items, and the platform demonstrated in a proof of concept is rarely the platform in the quote.
  • Ephemeral cloud instances consume asset entitlement until they age out of inventory, so an autoscaling group that creates and destroys hosts hourly can burn licence capacity on machines that existed for minutes, and controlling that means tuning purge policies rather than tuning the cloud.
  • Authenticated scanning produces materially better results than unauthenticated, but it requires storing and rotating privileged credentials for every target platform, which is a security project in its own right, and teams that skip it receive reports full of unconfirmed potential findings that nobody trusts.
  • The console is a set of modules with separate interfaces, search syntaxes and report engines, so an analyst moving between vulnerability management, policy compliance and web application scanning learns each one, and cross-module reporting usually ends in a spreadsheet or a script against the API.
  • The tool surfaces findings far faster than any organisation can remediate them, and it does not solve the ownership problem: without an agreed prioritisation policy and a named owner in IT operations, a first scan producing tens of thousands of findings becomes a dashboard that everyone learns to ignore.

Answered from the vendors’ own pages

Adyen: How much does Adyen charge per transaction?

Adyen charges a fixed $0.13 USD per transaction plus a variable fee based on the payment method used. Credit cards typically cost $0.13 + 0.60% + interchange, while digital wallets and BNPL options cost between $0.13 + 0.99% to $0.13 + 4.99%+, depending on the specific method and region.

Source
Qualys VMDR: Agent or scanner: which do I need?

Usually both. The agent covers endpoints and servers you control and gives continuous data; scanners cover devices you cannot install an agent on, such as network gear, printers and appliances, and provide the external perimeter view.

Adyen: Does Adyen have monthly subscription or setup fees?

No, Adyen has no setup fees or monthly recurring charges. You pay only for each transaction processed. The transaction fee structure remains the same regardless of transaction volume or business size.

Source
Qualys VMDR: Does it patch as well as detect?

Yes, through the Patch Management module, which is a separate subscription using the same agent. Core VMDR detects and prioritises but does not deploy fixes.

Adyen: What's Adyen's Interchange++ pricing option?

Adyen offers an Interchange++ transparent pricing model that passes interchange and scheme fees directly to merchants instead of bundling them into a percentage rate. This allows visibility into exact costs for each payment method.

Source
Qualys VMDR: How are assets counted for licensing?

By the number of assets in inventory, which includes cloud instances and containers depending on the modules in use. Short-lived cloud assets count until they are purged, so purge settings directly affect what you consume.

Adyen: Can I process payments in multiple currencies with Adyen?

Yes, Adyen supports 100+ payment methods across multiple currencies. You can link multiple bank accounts in different currencies to avoid currency conversion fees on international transactions.

Source
Qualys VMDR: Can I keep the data in a specific region?

Yes. Qualys operates several regional platform instances and you choose which one your subscription lives on. Moving between them later is not trivial, so decide before onboarding.

Qualys VMDR: Does it scan web applications?

Web Application Scanning is a separate module licensed per application, not part of core VMDR, and it is a dynamic scanner with the usual limits around authenticated flows in single-page applications.
