ADGUARD has just become the last VPN supplier to add quantum -resistant encryption to its software.
More specifically, Adguard VPN now incorporates a combination of conventional encryption methods with one of the post-quantum algorithm standards published by the National Institute of Standards and Technology (NIST) in August from last year. The functionality was deployed on MacOS and Windows on March 6, 2025, the mobile applications that should obtain the upgrade later in the month.
The company now follows in the footsteps of Google Chrome and some of the best VPN suppliers on the market by improving its encryption protections to ensure that user data is protected against new threats posed by quantum IT.
The need for quantum evidence
“We are at the edge of the era of quantum technology, and data protection must remain ahead of threats, not only react to them.
Experts predict that it is only a matter of time before quantum computers break current CRP encryption methods. This is mainly due to the fact that these machines will have the possibility of treating the calculations that today’s computers cannot manage in a few minutes.
Recent versions such as Google’s Willow quantum chip and Microsoft’s Majorana 1 chip, explains Adguard, “bring the quantum calculation of the resolution of complex worlds from the real world.” This can be an overview of what industry has been fearing for a long time – that current encryption will soon become obsolete.
Quantum computers are still a few years old to become current, but it is believed that cybercriminals have already adopted “Harvest Now, Decrypt” attacks later “. These involve malicious actors who collect encrypted data and decrypt it once the quantum machines are ready for the task.
It is exactly in this spirit that NIST experts published the first sets of quantum safety algorithms last year designed for specific tasks, namely protection for key exchanges (ML-KEM) and Authentication of identity (ML-DSA and SLH-DSA).
As mentioned earlier, Adguard VPN has implemented a hybrid encryption approach which includes the classic elliptical curve algorithm X25519 with the post-quantum algorithm Kyber768 ml-kem768.
This double -layer encryption approach, explains the supplier: “Ensures solid protection against current and future risks, allowing secure session keys which are resilient to the progress of quantum computers.”
This is exactly what the tastes of Google, Signal, Tuta Mail, ExpressVPN, NordVPN, Mullvad VPN, Windscribe and Purevpn have also done.
In simple terms, having a hybrid encryption method guarantees that proven algorithms always protect your data, even if post-health protection fails.
If you use the latest version of Adguard VPN on Desktop, you should already be able to activate this function via the Settings menu. This advanced safety option should also land on VPN iOS and Android applications in the coming weeks.
We test and examine the VPN services in the context of legal recreational uses. For example: 1 and 1 Access a service from another country (subject to the terms and conditions of this service). 2 Protect your online safety and strengthen your confidentiality online abroad. We do not support or tolerate the illegal or malicious use of VPN services. The consumption of hacked content that is paid is neither approved nor approved by the future publication.
