The short version

  • Only Arnica has a free tier, so it costs nothing to try first.
  • Each has a real cost: Arnica per-identity pricing ($25-$50/person/year) requires tracking active developers; 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.
  • They diverge on capability: Arnica covers AI SAST, Bitdefender VPN covers Suite integration.
  • 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.

Arnica

  • Per-identity pricing ($25-$50/person/year) requires tracking active developers
  • Overage identity tracking via 90-day PR activity can be unpredictable
  • Free plan limited to weekly updates, requiring upgrade for real-time scanning
  • Advanced add-ons (Image Scanning, AI SAST, Agentic Rules Enforcer) pricing not published
  • On-premises deployment limited to Enterprise tier

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.

Answered from the vendors’ own pages

Arnica: How are identities defined in Arnica pricing?

Identities are any users and other contributing entities that contributed code and/or had PR activity during the last 90 days. This ensures billing matches active developers.

Source
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.

Arnica: What is the annual discount?

Annual prepayment offers approximately 17% savings versus monthly billing. Core Business annual is $300/identity versus $360 for monthly.

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.

Arnica: Can I cancel or downgrade Arnica anytime?

Yes. Subscriptions can be cancelled or downgraded at any time. Overage identities receive automatic protection with true-up invoicing.

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.

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.
