Thoughts??

[Tracey]

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

[Zach91]

PQE/PQC is the future to protect our data

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.

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.

[James_46]

Corporate environments are taking it more seriously than consumer VPN services.

Long-term data protection and compliance requirements make future-proofing more relevant.

That is where hybrid approaches are being explored in a structured way.

Consumer products are mostly following that trend, but with more hype attached.

[IronQuarry]

Post-quantum VPNs are real, but the timeline is easy to exaggerate. Quantum computers capable of breaking current public key cryptography at scale are not sitting in every data centre waiting for someone to press the button.

That does not mean the preparation is pointless. Security changes usually happen before the emergency arrives because replacing infrastructure takes years.

The funny thing about security is that the boring planning stage is usually the part that prevents the exciting disaster story later.

A good VPN provider talking about post-quantum support should be explaining the actual algorithms and implementation, not just showing a picture of a glowing quantum computer.

[Rashford49]

One practical downside is increased handshake size and latency.

Post-quantum key exchanges tend to be heavier than traditional ones.

For most users it is negligible, but on mobile or slower connections it can add up.

So there are trade-offs, not just benefits.

[KnotKnull]

The term "quantum-secure VPN" is a bit newer than the underlying idea. The actual work on post-quantum cryptography has been going on for years, but companies have only recently started packaging it as a feature people can buy.

A lot of the marketing appeared because of the concern around "harvest now, decrypt later" attacks. Someone could collect encrypted traffic today and hope future quantum computers can break it.

The VPN itself is not magically quantum-proof though. The important part is the cryptographic algorithms being used for key exchange and authentication. The VPN is just the tunnel carrying it all.

[QuantumDay]

There is also a trust question. If a provider claims quantum security, you have to trust their implementation is correct.

Without transparency or audits, it is hard to verify.

So brand reputation and technical detail matter more than the label itself

[Arty Leah]

At this stage, it is interesting but not urgent for the average user. Worth keeping an eye on, not worth paying a premium for.

If it comes bundled at no extra cost, great.

If it is being sold as a must-have feature, that is where skepticism kicks in

[Glassy Crow]

I think the biggest benefit of the discussion is that it pushes people to look beyond the marketing names. A VPN already has several jobs, and adding post-quantum protection is only one piece of the puzzle.

A provider can claim quantum resistance and still have poor logging policies, weak account security or bad privacy practices.

It is a bit like buying a tank with excellent armour but forgetting to check if there is an engine inside.

For anyone choosing a VPN, the basics still matter: reputation, transparency, security audits and a clear explanation of what they actually protect against.

[TrainingGhost]

Part of the confusion comes from quantum computing itself being poorly understood by most people.

It gets treated like a magic switch that suddenly breaks everything.

Reality is more gradual and complex.

That makes it easier for vague claims to slip through unchallenged.

[NoLimitsOscar42]

The interesting part is how the phrase has moved from research papers into consumer products. A few years ago most people outside security circles would never have heard of post-quantum cryptography.

Now it is appearing in VPN announcements because companies know future-proofing is a selling point.

There is nothing wrong with that as long as the claims are accurate. Security improvements becoming easier for normal users to access is a good thing.

The only danger is making people think they need a "quantum VPN" because their laptop is going to be hacked by a quantum computer next Tuesday. That is probably a slightly more dramatic movie plot than reality.

[TommyB_20]

That last point is probably the most important one. There is a difference between a company adding post-quantum algorithms and a company sticking a big "quantum secure" label on a normal VPN subscription.

The useful question is what standards they actually support, not how futuristic the advert sounds. We have seen plenty of security products use scary words to sell ordinary features.

The transition is similar to older changes like moving away from weak encryption methods. It happens slowly because businesses have huge amounts of equipment and software that all need to work together.

For most home users, the risk is not that their weekend browsing is suddenly going to be cracked tomorrow. It is more relevant for governments, research organisations and companies protecting data that needs to stay private for decades.

[LunarDriftJaguar]

There is some value in early adoption though. Testing these algorithms in real-world conditions helps identify weaknesses.

Even if it is not essential yet, it pushes the ecosystem forward.

Just needs to be communicated clearly so people know what they are actually getting

[Gerrard]

A lot of it feels like a repeat of past security buzzwords. "Military-grade encryption" all over again, just updated for 2026.

The underlying tech may be solid, but the way it is presented can be exaggerated.

That gap between reality and marketing is where confusion creeps in.
