- 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.; Proton Mail paid plan pricing not displayed on vendor site

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.

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.
Proton Mail: Is there a free version of Proton Mail?
Yes, Proton Mail offers a free plan with 1 GB storage, 1 encrypted email address, and basic features like folders, labels, and filters.
SourceBitdefender 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.
Proton Mail: What does the Mail Plus plan include?
Mail Plus includes 15 GB storage, 10 encrypted email addresses, support for 1 custom domain, 10 hide-my-email aliases, priority support, and access to Proton Calendar.
SourceBitdefender 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.
Proton Mail: What is included in Proton Unlimited?
Proton Unlimited provides 500 GB storage, 15 email addresses, 3 custom domains, unlimited hide-my-email aliases, access to Mail, Calendar, VPN, Drive, and Pass, plus dedicated support.
SourceBitdefender 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.
Proton Mail: Does Proton Mail offer a money-back guarantee?
Yes, Proton Mail provides a 30-day money-back guarantee for paid plans.
SourceBitdefender 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.
