The short version

  • Only Keil MDK has a free tier, so it costs nothing to try first.
  • Each has a real cost: Keil MDK pricing for Essential and Professional subscriptions not disclosed on primary site; NordVPN a server in a Finnish datacentre was accessed in March 2018 through a remote management interface left exposed by the hosting provider, and NordVPN did not disclose it until October 2019, so a buyer relying on the company's transparency is relying on a track record that includes a nineteen-month delay.

Where each one falls short

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

Keil MDK

  • Pricing for Essential and Professional subscriptions not disclosed on primary site
  • Customers must contact Arm Developer Tools store for subscription rates

NordVPN

  • A server in a Finnish datacentre was accessed in March 2018 through a remote management interface left exposed by the hosting provider, and NordVPN did not disclose it until October 2019, so a buyer relying on the company's transparency is relying on a track record that includes a nineteen-month delay.
  • Pricing depends on a long initial term and reverts to the standard rate at renewal, so the monthly figure that justified the purchase is not what the subscriber pays in the third year, and the cheapest way to stay is usually to cancel and re-subscribe.
  • Panamanian registration is selected for the absence of a data retention law, but it also means a subscriber with a dispute has little practical recourse, and the protection rests on a corporate structure the customer cannot inspect or enforce against.
  • NordLynx is unavailable for manual and router configurations, so the one device that could cover an entire home network falls back to OpenVPN or IKEv2 with the associated throughput loss, and obfuscated servers likewise only run over OpenVPN.
  • Features such as Threat Protection are implemented in the client rather than in the network, so any device using a manual configuration, a router or an unsupported platform receives a bare tunnel without the protections the subscription is sold on.

Answered from the vendors’ own pages

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
NordVPN: What jurisdiction is NordVPN under?

The VPN service company is registered in Panama, which has no mandatory data retention law for these services. The wider Nord Security group operates from Lithuania.

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
NordVPN: Has the no-logs claim actually been audited?

Yes, more than once. PwC Switzerland examined it in 2018 and 2020 and Deloitte in later engagements. Each is a point-in-time assurance report over stated policy and server configuration, not ongoing monitoring.

NordVPN: What happened in the 2018 breach?

An attacker reached one rented server in Finland via an insecure remote management tool left in place by the datacentre provider, and obtained a TLS key that had expired. NordVPN disclosed it in October 2019, nineteen months later, and afterwards moved the estate to RAM-only servers.

NordVPN: How many devices does one subscription cover?

Ten simultaneous connections. A router configured with the service counts as one connection regardless of how many devices sit behind it.

NordVPN: Does it work on restrictive networks?

There are obfuscated servers intended for networks that block VPN protocols, but they run over OpenVPN only and no provider can guarantee access in a country that actively filters. Treat it as best effort.
