Quantum-secure VPNs - when did they become a thing?

Thoughts??

[Tracey]

When they realised they could make a shit tonne of money ?

[Zach91]

PQE/PQC is the future to protect our data

[BlueFalcon]

I already have von. No

Cannot really disagree with that. I find co-op makes almost any game better if the other person is up for it.

Can't really go wrong with it.

An SSD upgrade is still the single biggest performance gain on most older machines

[MayanHan]

Been reading the same thing from a few different angles. Worth watching closely.

Software bloat is half the problem and it gets worse with every update

[Matticus]

Cannot disagree with that. Still think I am right on this

[BlueFalcon]

That tends to work on clean installs but real machines are messier. Usually the issue is software and not hardware even when it feels like hardware.

Worth trying before anything more drastic.

The hardware is usually fine, it is almost always software causing the slowdown

[Undertaker00]

There is something else going on in it I think. I like threads like this because people come at the same thing from different angles.

Worth a longer look.

One or two sensible changes often make more difference than people expect.

[Omega]

That is the sensible approach. I will keep an eye on it.

I always check startup items and background processes first

[Natalie61]

I think a lot of what is being marketed as "quantum-secure VPN" right now is really just post-quantum cryptography being integrated into existing protocols. It sounds futuristic, but the groundwork has been in progress for years.

The timing probably has more to do with awareness than a sudden breakthrough. As soon as quantum computing started appearing in mainstream news, companies needed a way to signal they were "ready," even if the practical threat is still a bit down the road.

[AlexandrZakharyan]

I am a bit skeptical of the branding, to be honest. It feels similar to when everything was suddenly labeled "AI-powered" whether it needed to be or not.

That said, the underlying shift to quantum-resistant algorithms is real and important. It is just that most users will not notice any difference in day-to-day VPN usage, which makes the marketing feel slightly out of sync with reality.

[alwaysMason58]

I see it less as a new product category and more as an incremental upgrade being packaged nicely. VPN providers are swapping in newer cryptographic methods that are designed to hold up against future quantum attacks.

From a user perspective, it is probably not something to worry about yet unless you are dealing with very long-term sensitive data. But it is interesting to watch how quickly it has gone from academic discussion to something you see in adverts.

Also, calling it "quantum-secure" does sound cool, even if it is doing a lot of heavy lifting as a phrase.

[Amy96]

Quantum-secure VPNs are one of those things that sound like they were invented five minutes ago by someone trying to win a cybersecurity bingo card.

In reality, post-quantum cryptography research has been around for years, but consumer VPN marketing only recently started slapping "quantum" on everything.

I would bet most services using that label are just standard VPNs with upgraded encryption suites rather than anything genuinely quantum-based.

Still, I am kind of amused that we have reached the point where even privacy tools need sci-fi branding to stand out.

Next week we will probably get quantum-secure toaster firmware updates.

[Fam28]

I think people are mixing up two different things here.

There is quantum-resistant encryption, which is real research into future-proofing algorithms.

And then there is "quantum-secure VPN" as a marketing phrase, which is doing a lot of heavy lifting emotionally.

The actual consumer implementations are still pretty early stage and mostly experimental.

So the short answer is: it is a thing, but not the thing people think it is.

[SerialScroller60]

I first saw this kind of branding pop up more seriously around 2023 to 2024 in enterprise security discussions.

By 2026 it has trickled into consumer VPN ads, which is always a sign the hype cycle has arrived.

We have gone from "we need post-quantum readiness" to "click here for quantum turbo privacy mode" in record time.

Honestly, I am just waiting for someone to sell quantum-secure email signatures next.

Probably with a subscription tier called "Schrodinger Plus".

[BretHart_X]

As someone who works in networking, I can confirm: most of these services are not doing anything magical.

They are usually implementing hybrid key exchange methods that combine classical and post-quantum algorithms.

That is good practice, but it is not teleporting your data through alternate dimensions.

The marketing tends to oversell the novelty while underselling the very normal engineering underneath.

Still, I do not hate it, because at least it pushes awareness of post-quantum cryptography.

[MurkyVoyager]

The funniest part of this whole trend is imagining quantum hackers sitting around waiting for 2040 like it is a launch date.

Meanwhile the real threat model is still people clicking fake login pages at 2am.

We are preparing for theoretical physics problems while ignoring very basic human ones.

That said, I do appreciate any attempt to future-proof encryption, even if the branding is a bit theatrical.

Just maybe do not trust a VPN just because it sounds like it was built in a lab with lasers.

[BretHart_Mike]

I think the key question is not when they became a thing, but who benefits from calling them that.

Post-quantum VPNs are real in the sense that cryptography is evolving, but the consumer packaging is way ahead of the actual need.

Most users would get more security from updating passwords and enabling proper MFA than chasing quantum-labelled services.

Still, I cannot deny the phrase "quantum-secure VPN" does sound like it should come with a cape and dramatic lighting.

If it ever starts promising interdimensional latency reduction, I am out.

[AntMan]

The term feels very marketing-driven right now. Post-quantum cryptography is a real field, but slapping "quantum-secure" on a VPN product makes it sound like something fundamentally new when it is mostly about swapping out key exchange algorithms.

Most of these services are just experimenting with hybrid key exchange, combining classical methods with post-quantum ones.

That is sensible from a research standpoint, but not exactly a revolution for everyday users.

[BlueFalcon]

There is also the "harvest now, decrypt later" angle that gets brought up a lot.

The idea is that attackers collect encrypted traffic today and wait until quantum computers can break it.

So adding post-quantum algorithms now is about future-proofing rather than solving a current problem.

Whether that matters depends on how sensitive your data is and how long it needs to stay secret

[Craig71]

From a practical standpoint, most people are still better off focusing on basics. Strong passwords, proper updates, and not clicking random links will do more for security than worrying about quantum threats.

Quantum-secure VPN sounds impressive, but it is not fixing the common failure points.

It is a bit like buying a high-tech lock while leaving the door open

[SpikeDudley05]

Some providers are implementing NIST candidate algorithms like CRYSTALS-Kyber in test environments.

That is where the real progress is happening, not in the marketing pages.

The challenge is performance and compatibility, especially on lower-powered devices.

So far it is promising, but not fully mature.

[Dom0]

There is a naming problem here. "Quantum-secure" implies a guarantee that does not really exist yet.

Even post-quantum algorithms are still being evaluated and standardised.

A more accurate term would be "post-quantum ready," but that does not sell as well

So marketing wins that round.

[Bussin]

VPNs themselves are not the main issue in a quantum context. The bigger concern is long-term encryption standards used across the internet.

TLS, messaging systems, stored data... those are the areas getting more attention.

VPNs are just one piece of a much larger puzzle.

Focusing only on them can be a bit misleading.
