The short version

  • Only Keil MDK has a free tier, so it costs nothing to try first.
  • Each has a real cost: CyberGhost VPN kape Technologies, the parent, was formerly Crossrider, a browser extension platform whose technology was widely used to distribute adware, and Kape now also owns VPN review sites, so third-party rankings a buyer might use to verify the product can come from the same corporate group.; Keil MDK pricing for Essential and Professional subscriptions not disclosed on primary site

Where each one falls short

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

CyberGhost VPN

  • Kape Technologies, the parent, was formerly Crossrider, a browser extension platform whose technology was widely used to distribute adware, and Kape now also owns VPN review sites, so third-party rankings a buyer might use to verify the product can come from the same corporate group.
  • Pricing is structured so that the deep discount applies to the longest initial term and the standard rate applies at renewal, which means the figure used to make the decision is not the figure paid in year three unless the subscriber renegotiates or churns.
  • The Deloitte engagement is point-in-time assurance over stated policy and server configuration, so it confirms things were as described when examined and says nothing about how the infrastructure behaves today or after an ownership change.
  • Client capability differs sharply by platform: the Linux client is command-line only and lacks the kill switch and split tunnelling that the Windows client has, so a mixed-device household does not get the protection that reviews of the Windows app describe.
  • Streaming-optimised server labels go stale because platforms block address ranges continually, and the practical support answer is to try a different server, which makes the labelled-server feature less dependable than the marketing implies.

Answered from the vendors’ own pages

CyberGhost VPN: Who owns CyberGhost?

Kape Technologies, which acquired it in 2017. Kape was formerly called Crossrider and also owns ExpressVPN, Private Internet Access and Zenmate, plus the review sites vpnMentor and Wizcase.

Keil MDK: Does Keil MDK have a free version?

Yes, Keil MDK Community Edition is free for non-commercial projects. Essential and Professional editions are available as monthly or annual subscriptions.

Source
CyberGhost VPN: Has the no-logs claim been independently audited?

Yes. Deloitte has examined the no-logs policy and server configuration and published an assurance report. Note that this is a point-in-time engagement, not continuous monitoring.

Keil MDK: How much do Keil MDK paid editions cost?

Specific pricing for Essential and Professional editions is not published on the main site. Rates are available from the Arm Developer Tools store or by contacting Arm sales.

Source
CyberGhost VPN: What jurisdiction is it under?

The service is operated from Romania, which has no mandatory communications data retention law in force and is not a member of the Five, Nine or Fourteen Eyes intelligence-sharing arrangements. Ownership sits with Kape, headquartered in the UK.

CyberGhost VPN: Does it work with streaming services?

Often, using the servers labelled for each service, but this changes constantly as platforms block address ranges. Treat streaming access as a feature that may stop working on any given day rather than a guarantee.

CyberGhost VPN: Can I use it on Linux or a router?

There is a command-line Linux client with fewer features than the desktop apps, and router use requires manual OpenVPN configuration rather than an official app.
