IVPN has undergone a [no-logging audit from Cure53](https://cure53.de/audit-report_ivpn.pdf) which concluded in agreement with IVPN's no-logging claim. IVPN has also completed a [comprehensive pentest report Cure53](https://cure53.de/summary-report_ivpn_2019.pdf) in January 2020. IVPN has also said they plan to have [annual reports](https://www.ivpn.net/blog/independent-security-audit-concluded) in the future. A further review was conducted [in April 2022](https://www.ivpn.net/blog/ivpn-apps-security-audit-2022-concluded/) and was produced by Cure53 [on their website](https://cure53.de/pentest-report_IVPN_2022.pdf).
As of February 2020 [IVPN applications are now open-source](https://www.ivpn.net/blog/ivpn-applications-are-now-open-source). Source code can be obtained from their [GitHub organization](https://github.com/ivpn).
#### :material-check:{ .pg-green } Accepts Cash and Monero
In addition to accepting credit/debit cards and PayPal, IVPN accepts Bitcoin, **Monero** and **cash/local currency** (on annual plans) as anonymous forms of payment.
IVPN [recommends](https://www.ivpn.net/wireguard/) the use of WireGuard with their service and, as such, the protocol is the default on all of IVPN's apps. IVPN also offers a WireGuard configuration generator for use with the official WireGuard [apps](https://www.wireguard.com/install/).
IVPN previously supported port forwarding, but removed the option in [June 2023](https://www.ivpn.net/blog/gradual-removal-of-port-forwarding). Missing this feature could negatively impact certain applications, especially peer-to-peer applications like torrent clients.
In addition to providing standard OpenVPN configuration files, IVPN has mobile clients for [App Store](https://apps.apple.com/us/app/ivpn-serious-privacy-protection/id1193122683), [Google Play](https://play.google.com/store/apps/details?id=net.ivpn.client), and [GitHub](https://github.com/ivpn/android-app/releases) allowing for easy connections to their servers.
IVPN clients support two factor authentication (Mullvad's clients do not). IVPN also provides "[AntiTracker](https://www.ivpn.net/antitracker)" functionality, which blocks advertising networks and trackers from the network level.
> Cure53とAssured ABは監査の結果に満足しており、このソフトウェアは全体的に好印象を残した。 With security dedication of the in-house team at the Mullvad VPN compound, the testers have no doubts about the project being on the right track from a security standpoint.
In 2020 a second audit [was announced](https://mullvad.net/blog/2020/6/25/results-available-audit-mullvad-app/) and the [final audit report](https://cure53.de/pentest-report_mullvad_2020_v2.pdf) was made available on Cure53's website:
> The results of this May-June 2020 project targeting the Mullvad complex are quite positive. [...] The overall application ecosystem used by Mullvad leaves a sound and structured impression. The overall structure of the application makes it easy to roll out patches and fixes in a structured manner. More than anything, the findings spotted by Cure53 showcase the importance of constantly auditing and re-assessing the current leak vectors, in order to always ensure privacy of the end-users. With that being said, Mullvad does a great job protecting the end-user from common PII leaks and privacy related risks.
In 2021 an infrastructure audit [was announced](https://mullvad.net/en/blog/2021/1/20/no-pii-or-privacy-leaks-found-cure53s-infrastructure-audit/) and the [final audit report](https://cure53.de/pentest-report_mullvad_2021_v1.pdf) was made available on Cure53's website. Another report was commissioned [in June 2022](https://mullvad.net/en/blog/2022/6/22/vpn-server-audit-found-no-information-leakage-or-logging-of-customer-data/) and is available on [Assured's website](https://www.assured.se/publications/Assured_Mullvad_relay_server_audit_report_2022.pdf).
Mullvad provides the source code for their desktop and mobile clients in their [GitHub organization](https://github.com/mullvad/mullvadvpn-app).
#### :material-check:{ .pg-green } Accepts Cash and Monero
Mullvad, in addition to accepting credit/debit cards and PayPal, accepts Bitcoin, Bitcoin Cash, **Monero** and **cash/local currency** as anonymous forms of payment. They also accept Swish and bank wire transfers.
Mullvad [recommends](https://mullvad.net/en/help/why-wireguard/) the use of WireGuard with their service. It is the default or only protocol on Mullvad's Android, iOS, macOS, and Linux apps, but on Windows you have to [manually enable](https://mullvad.net/en/help/how-turn-wireguard-mullvad-app/) WireGuard. Mullvad also offers a WireGuard configuration generator for use with the official WireGuard [apps](https://www.wireguard.com/install/).
Mullvad allows you to [access services hosted on IPv6](https://mullvad.net/en/blog/2014/9/15/ipv6-support/), as opposed to other providers which block IPv6 connections.
Mullvad previously supported port forwarding, but removed the option in [May 2023](https://mullvad.net/en/blog/2023/5/29/removing-the-support-for-forwarded-ports/). Missing this feature could negatively impact certain applications, especially peer-to-peer applications like torrent clients.
Mullvad has published [App Store](https://apps.apple.com/app/mullvad-vpn/id1488466513) and [Google Play](https://play.google.com/store/apps/details?id=net.mullvad.mullvadvpn) clients, both supporting an easy-to-use interface as opposed to requiring you to manually configure your WireGuard connection. The Android client is also available on [GitHub](https://github.com/mullvad/mullvadvpn-app/releases).
Mullvadは、どのノードを[所有またはレンタル](https://mullvad.net/en/servers/)しているのかについて非常に透明性があります。 They use [ShadowSocks](https://shadowsocks.org/) in their ShadowSocks + OpenVPN configuration, making them more resistant against firewalls with [Deep Packet Inspection](https://en.wikipedia.org/wiki/Deep_packet_inspection) trying to block VPNs. Supposedly, [China has to use a different method to block ShadowSocks servers](https://github.com/net4people/bbs/issues/22). Mullvad's website is also accessible via Tor at [o54hon2e2vj6c7m3aqqu6uyece65by3vgoxxhlqlsvkmacw6a7m7kiad.onion](http://o54hon2e2vj6c7m3aqqu6uyece65by3vgoxxhlqlsvkmacw6a7m7kiad.onion).
**私たちは、推奨するいずれのプロバイダーとも提携していません。 This allows us to provide completely objective recommendations.** In addition to [our standard criteria](about/criteria.md), we have developed a clear set of requirements for any VPN provider wishing to be recommended, including strong encryption, independent security audits, modern technology, and more. We suggest you familiarize yourself with this list before choosing a VPN provider, and conduct your own research to ensure the VPN provider you choose is as trustworthy as possible.
We require all our recommended VPN providers to provide OpenVPN configuration files to be used in any client. **If** a VPN provides their own custom client, we require a killswitch to block network data leaks when disconnected.
**Minimum to Qualify:**
- Support for strong protocols such as WireGuard & OpenVPN.
- Killswitch built in to clients.
- Multihop support. Multihopping is important to keep data private in case of a single node compromise.
- If VPN clients are provided, they should be [open-source](https://en.wikipedia.org/wiki/Open_source), like the VPN software they generally have built into them. We believe that [source code](https://en.wikipedia.org/wiki/Source_code) availability provides greater transparency about what your device is actually doing.
A VPN is pointless if it can't even provide adequate security. We require all our recommended providers to abide by current security standards for their OpenVPN connections. Ideally, they would use more future-proof encryption schemes by default. We also require an independent third-party to audit the provider's security, ideally in a very comprehensive manner and on a repeated (yearly) basis.
