The short version

  • Only Keycloak has a free tier, so it costs nothing to try first.
  • Each has a real cost: Bitdefender VPN the network is not Bitdefender's: the servers and the Catapult Hydra protocol are licensed from Aura, formerly Pango and AnchorFree, so the company physically handling your traffic and subject to legal process is a United States based third party, not the Romanian vendor whose brand is on the client.; Keycloak requires self-hosted deployment and operational expertise to install, configure and maintain
  • 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.

Bitdefender VPN

  • The network is not Bitdefender's: the servers and the Catapult Hydra protocol are licensed from Aura, formerly Pango and AnchorFree, so the company physically handling your traffic and subject to legal process is a United States based third party, not the Romanian vendor whose brand is on the client.
  • Catapult Hydra is proprietary and closed source, so unlike OpenVPN or WireGuard there is no public implementation for researchers to audit, and a buyer choosing on cryptographic grounds has nothing to inspect.
  • There is no published independent no-logs audit of this service comparable to the Deloitte, PwC and KPMG engagements the standalone VPN vendors commission, so the no-logging position rests on the privacy policies of two separate companies rather than on any external assurance.
  • The free tier bundled with the antivirus suites is capped at a small daily allowance and selects the server for you, so it is a demonstration rather than a usable VPN, and customers who assumed their suite included a VPN find they need a further paid upgrade.
  • Feature depth is well below the dedicated market: no port forwarding, no dedicated IP, no multi-hop, no city-level server selection and no Linux or router client, so routers, NAS devices, consoles and anything needing an inbound connection cannot be covered at all.

Keycloak

  • Requires self-hosted deployment and operational expertise to install, configure and maintain
  • No managed cloud option provided by Red Hat; organisations must operate infrastructure themselves or use third-party distributions
  • Clustering and high-availability configurations require additional operational knowledge
  • Community support only; commercial support requires third-party vendors or distributions

Answered from the vendors’ own pages

Bitdefender VPN: Who actually operates the servers?

The underlying VPN network and the Catapult Hydra protocol are licensed from Aura, previously known as Pango and AnchorFree, the operator of Hotspot Shield. Bitdefender identifies the arrangement in its VPN terms. Your traffic therefore passes through a United States based provider's infrastructure.

Keycloak: What protocols does Keycloak support?

Keycloak supports OpenID Connect, OAuth 2.0 and SAML 2.0 protocols for authentication and authorisation.

Source
Bitdefender VPN: Is the free version enough?

Only as a taster. It is capped at a small daily traffic allowance and chooses the server itself, which rules out streaming and any sustained use. It exists to demonstrate the feature inside the antivirus suite.

Keycloak: Can Keycloak integrate with existing user directories?

Yes. Keycloak supports user federation with LDAP and Active Directory systems, allowing organisations to leverage existing user directories.

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

There is no published independent no-logs audit of this service equivalent to those commissioned by the dedicated VPN providers. If an audited no-logging claim is what you are buying, this is not the product for it.

Keycloak: Is Keycloak free?

Yes. Keycloak is fully open-source and free to deploy and use. No licensing fees are required.

Source
Bitdefender VPN: Does it work with streaming services?

Sometimes, but it is not built around that use case, there is no per-service server labelling, and there is no commitment to restoring access when a platform blocks a range. A streaming-focused provider is a better fit if that is the reason you want a VPN.

Bitdefender VPN: Can I run it on Linux or a router?

No. There is no Linux client and no router firmware or manual configuration option, so coverage is limited to the Windows, macOS, iOS and Android clients.
