In a dangerous era for journalism – a powerful new tool to help protect sources

The Guardian09-06-2025

Today, the Guardian launches a unique new tool for protecting journalistic sources. Secure Messaging is an important new technological innovation that will make it easier for people to share confidential information with us.
Blowing the whistle on wrongdoing has always taken bravery. As threats to journalists around the world increase, so does the need to protect confidential sources. One of the most dramatic global shifts against whistleblower safety comes as part of the Trump administration's continued assault on the free press.
Investigative reporting is extremely important to the Guardian; we have been exposing wrongdoing and scrutinising power with complete independence for decades. We know first-hand how impactful investigations depend on trusted reader-reporter interactions. From the Frank Hester revelations to the Pegasus project, Uber files, Pandora papers and the Michelle Mone/PPE Medpro scandal, many of our most powerful recent investigative projects – as well as our biggest stories throughout the decades – have relied on sources feeling confident they can safely share information with the Guardian or our reporting partners. Secure Messaging is the latest tool in our armoury to protect whistleblowers.
Built by our product and engineering team, in partnership with the University of Cambridge's department of computer science ​and technology​, Secure Messaging is unlike traditional information-sharing platforms​. The technology behind Secure Messaging conceals the fact that messaging is taking place at all by making the communication indistinguishable from other data sent to and from the app by our millions of regular users. By using the Guardian app, other users are effectively providing 'cover' and helping us to protect sources.
Secure Messaging is not just a tool for the Guardian. As part of our commitment to protecting the media and the public interest globally, the Guardian has published the source code for the technology that enables this system. This means that other organisations will be able to use this technology freely to implement secure messaging tools within their own apps.
If you have any information to share with us, you can use Secure Messaging within the Guardian app by clicking on the app menu and scrolling to 'Secure Messaging'. For more information on how to share tips with our journalists please read our comprehensive guide.

I tried world's thinnest vacuum at Dyson's labs – skinny ‘PencilVac' is the SAS of cleaning gear with three killer perks

Sean Keach, Head of Technology and Science Published: Invalid Date, AM I really looking forward to cleaning? Dyson has achieved two impossible feats: making me thrilled about the idea of tidying the floor, and inventing the world's slimmest vacuum. I'm not sure which is more impressive. 10 It's called the PencilVac, and I've had a go with it behind closed doors at Dyson's Oxfordshire labs. Before I even grabbed the thing, I was blown away. Surely this is just a broom in disguise? Is Sir James Dyson having me on? It measures a frankly ludicrous 38mm across. That's about three Dairy Milk bars stacked on top of each other. BIN-CREDIBLE! All of the usual Dyson tech – the batteries, bin, and motor – has been crammed into the handle. So you've got battery cells at the top, followed by the computer system, then a shrunken motor that's Dyson's fastest yet. Next comes the bin, which uses a new compression system to fit five times more dust than its apparent 0.08-litre capacity. After all, Dyson tells me that most of a 'full' bin is usually air – so there's plenty of room for squashing. Then there's a dust separation mechanism, brush bars, and a Fluffycones cleaner head with a cone design that shifts long hair off to the side – so it can be sucked back up instead of requiring you to cut it out with scissors. You don't see most of this, of course. PencilVac just looks like a Dyson that's been hitting the treadmill. I'LL Naturally it all sounds like a vacuum cleaning dream, so I grab the handle and away I go. Watch Sir James Dyson unveil secret PencilVac, world's slimmest vacuum cleaner 10 It's feathery light and easy to manoeuvre. Dyson has built a kind of vacuum cleaning assault course for me that I whizz along effortlessly. I suspect my success is down to the gadget's hi-tech design and not my own cleaning skill – but they don't crush my dreams. This course has straights and hairpin bends – the Nürburgring of vacuuming. And at the end is a low shelf that I drop straight under. This thing lays almost flat – which is no surprise, given that is pretty much is flat. DYSON PENCILVAC – THE TECH SPECS Here's what you need to know... Size: 38mm x 226mm x 1,160mm (W x L x H) Weight: 1.8 kilos Motor: Dyson Hyperdymium 140k motor Motor RPM: 140,000 Filtration: Up to 99.99% (dow to 0.3 microns) Runtime: Up to 30 minutes Charge time: Four hours Cleaner Head: Fluffycones cleaner head (for detangling long hair and to-edge cleaning) Accessories: Rotating combi-crevice tool / conical hair screw for mattresses and stairs / magnetic floor-charging dock Picture Credit: Dyson 10 It feels like a tactical weapon: the sort of thing that SAS squaddies would use if dust mites were the baddies. Helping this image is a built-in laser that exposes dirt and debris. It's the vacuuming equivalent of night vision goggles and a red-dot sight. I dart between objects with stunning agility. I was born to do this. The room fades away. I daydream about running off with it, and living out my days as a kind of vacuuming sensei, cleaning the most complicated floor-spaces I can find. But I can't become Dyson's Mr Miyagi just yet, because the PencilVac isn't out until 2026, and still doesn't have a UK price. SIR JAMES DYSON SPEAKS TO THE SUN Here's what famed British inventor Sir James Dyson told The Sun's Sean Keach... Does PencilVac mark the beginning of a whole new era for vacuum cleaner design? Yes, it's a reinvention of the format of the vacuum cleaner – our third reinvention in fact! We started off by removing the bag to ensure vacuums didn't lose suction. Then we pioneered the simplicity and ease of cleaning with really powerful battery-powered cordless vacuums, which were lighter and much easier to use. Now, with the Dyson PencilVac, we're taking it a stage further, pioneering a new way to clean. All the technology is contained in a very slim handle that is just 38mm in diameter. The new Fluffycones cleaner head floats across floors making it very manoeuvrable as you clean; all while it detangles long hair, so you don't have to worry about that. A vacuum cleaner this thin must have seemed impossible for years – when did you first realise it was possible to actually manufacture a working device like this? When something seems impossible, it makes us as engineers want to solve it all the more! Especially if people say, 'It can't be done.' I've wanted to make a vacuum like the Dyson PencilVac for many years. But it required us to miniaturise everything about the product – which is a huge task. The diameter of our hair tools was the inspiration. Through lots of research, we realised that 38mm is the optimal size for most people to hold, and so this was the diameter chosen for our hair tools like the Supersonic hair dryer and Airwrap multi-styler and dryer. In order to fit it in the handle of the machine, we had to reengineer every component of the motor – down to the micron – while increasing its speed to 140,000RPM and maximising its power density for high-performance. It was clear that we couldn't use cyclones for the dust separation, because they were too big for the 38mm diameter, so we had to develop something entirely new. The new slim, in-line format meant we could use dust compression technology in a small diameter, but over a long area to maximise the bin capacity, all while ensuring effective filtration performance and no loss of suction. What was the biggest challenge to overcome in building the PencilVac? Developing the new Fluffycones cleaner head was perhaps the greatest challenge we faced – but also the most rewarding! We wanted to develop a cleaner head that would detangle hair, clean right up to skirting boards, and pick up dust and debris in all directions – a cleaner head that would solve many frustrations with existing cleaner heads. The new Fluffycones cleaner head features four conical brush bars. The challenge was engineering the drive system to ensure that all four cones, which are powered by two motors and four epicyclic gear boxes, spin at the same, consistent speed while maintaining its 7.5-degree angle for optimal pick-up performance. I'm delighted not only that we managed this, but in doing so made a vacuum cleaner which is a joy to use. Who do you see PencilVac being the perfect vacuum cleaner for? Once you've used it, and felt it float effortlessly across the floor, you'll realise it's unlike anything that has come before. It may be the only vacuum cleaner you need! Picture Credit: Dyson 10 CLEAN-UP TIME It's a thrilling bit of kit, which might be the first time that's ever been said about a vacuum cleaner. This thing is easy to use, takes up very little space, and gets into difficult nooks and crannies. It feels purpose-built for British homes. It'll make cleaning under and around the dining table an absolute breeze. A treat, even. It really is the SAS of cleaning gear: it's light and agile for tactical cleaning operations, it dispatches long hairs with ruthless efficiency, and it has whole-house endurance with a 30-minute runtime. I can already see myself arguing with my wife over who gets to use the PencilVac – but no matter who does, everyone's a winner. Maybe that's the real Dyson magic. 10 10

Zuckerberg's political shift didn't shock Meta staff: ‘The whole time this was all one inch underneath'

Meta CEO Mark Zuckerberg 's recent public support for President Donald Trump did not come as a shock to those who know or have closely worked with him, with dozens of people saying some changes at the company are part of the tech billionaire's long-held beliefs. Dozens of people who have either worked with or known Zuckerberg told the Financial Times that the CEO's more public shift toward Trump is just Zuckerberg displaying the more 'authentic' version of himself to the world, even though he was once known to support liberal ideology and voiced opposition to Trump's policies during the first administration. 'Mark was trying to keep his real feelings tight inside and put on a suit and cut his hair and be a good boy. But the whole time this was all one inch underneath,' an unnamed Meta insider told the outlet. 'Then he said, 'F*** it. I might as well be the person I really am.'' Since Trump was elected in November, the Meta CEO has met with Trump at Mar-a-Lago, donated $1 million to Trump's inaugural fund, attended the inauguration, co-hosted a reception, and changed company policy to align more closely with the administration. Insiders told the newspaper that the tech billionaire's unapologetic pro-'masculine energy', free speech-loving shift is only a shift to the public. 'The public is seeing him more how we have, internally, since the beginning.' Andrew Bosworth, Meta's CTO, told FT. Bosworth suggested that Zuckerberg's former suit-wearing, government-obeying self was just the Meta CEO doing what he thought he was supposed to be doing. The Independent has asked the White House for comment. Meta declined to comment for this story. Zuckerberg's private shift toward more conservative figures, such as Trump, was reportedly a slow movement that was seemingly triggered by constant pushback against Facebook – Meta's former name – from both the public and lawmakers, especially those seeking to regulate the tech industry. One major shift came in 2020, when Biden administration officials pressured Zuckerberg to censor misinformation about Covid on his social media platform, which he did and later regretted. But under the Trump administration, Zuckerberg appears less concerned with appeasing the public. Appearing on Joe Rogan's podcast recently, the Meta CEO said he believes 'masculine energy is good.' Even when executives challenged Zuckerberg's comments, he refused to apologize. Those familiar with Zuckerberg told FT that his decision to lean into hobbies such as Brazilian jiu-jitsu or wear more streetwear or cozy up to the administration is all part of Zuckerberg's efforts to get people to like him. 'He saw that Elon Musk was popular among the tech bros,' a former insider said. 'There was a push to make him cool. The core of the Social Network movie is true — he just wants people to like him.'

Open Banking Won't Work Without Trust. Here's How We Enable That.: By Mathieu Altwegg

Open banking isn't just a regulatory shift - it's a generational opportunity. For the UK, one of the most digitally connected economies in the world, it offers a pathway to make managing money simpler, smarter, and more rewarding. It holds the promise for consumers to move money instantly, access better financial tools, switch providers effortlessly, and view their entire financial lives in real time. That future is no longer theoretical - it's here and now is the time for it to scale, but only with the right catalyst. From in-game purchases to managing cross-border transfers, Open Banking is already enabling faster, more flexible money movement. For the consumer, convenience is king. In 2023 alone, 70% of all UK online purchases were made via mobile phones, while over 90% of in-store transactions used contactless. The shift in consumer behaviour is clear: people expect seamless, secure, and intuitive ways to pay – if they trust it they will use it. Yet adoption in the UK remains uneven. Many consumers are still hesitant to embrace open banking as a way to pay - often due to concerns around protection, limited awareness, and inconsistent user experiences. The underlying technology is strong, but trust has yet to catch up. And trust isn't built overnight - it's earned through consistent focus, sustained investment, and a relentless commitment to putting customers first. It goes beyond fraud prevention; it's also about how issues are handled when things go wrong. If a consumer makes a payment to a business and doesn't receive the goods or services, they need the reassurance that they'll be reimbursed. The same goes for merchants – while cost savings and speed are attractive, many have proved reluctant to embrace pay by bank without the systems in place to smoothly handle disputes. Why would they risk turning a hard-won customer into a net cost if something goes wrong? These are the kinds of safeguards that will turn curiosity into confidence, and that's the gap we need to close. Simplicity and Control will Drive Trust and Uptake At its heart, open banking is about giving people more choice. Whether it's streamlining loan applications, enabling one-click checkout, or bringing together multiple accounts into a single, real-time view - open banking empowers consumers to manage their finances on their own terms. Recurring payments are a clear example. Today, Direct Debit dominates but brings friction: delays due to failed payments, manual work to match payments and records, and user visibility. Variable Recurring Payments (VRPs), enabled by open banking, offer a compelling alternative: real-time availability of funds, enhanced transparency, and greater user control. That translates into fewer payment failures and more predictable cash flow for businesses and consumers alike. But it is account-to-account (A2A) payments backed by a trusted provider with additional protections and features that will cement open banking as a go-to mechanism. Open banking unlocks powerful consumer features: tracking subscriptions and bills in one place, setting limits, and stopping unwanted charges. These convenient experiences will build trust, but consumers are both savvy and cautious; aware that risk still exists. They will need the presence of a trusted independent player in the payment process who can provide them protection. Collaboration Is the Key to Change The opportunity is enormous. Innovate Finance estimates that growing the UK's fintech ecosystem - where open banking is foundational - could unlock £328 billion in value over the next five years. But realising that value requires collaboration and consensus. No single organisation can do this alone. It will take coordinated efforts across banks, fintechs, payment providers, and policymakers to deliver consumer-friendly infrastructure that connects easily and works across providers. That's why we support collaborative A2A solutions that are open, secure, and built to scale - because a rising tide lifts all boats. Businesses Needs to Be Part of the Open Banking Story While the consumer opportunity is front of mind, the potential for business-to-business payments is just as transformational. Open banking can modernise how companies - from SMEs to large enterprises - manage cash flow, settle invoices, and access working capital. We should be pushing the boundaries of what's possible, not just for consumers, but for all users of the financial system. A UK Leadership Opportunity The UK has a proven track record of leading in payments innovation - from contactless adoption to the rise of challenger banks and embedded finance. The next leadership opportunity lies in scaling open banking, not just by improving the technology behind the scenes, but by embedding usability and trust across the ecosystem. The policy landscape is moving in the right direction. In her 2024 Mansion House speech, Chancellor Rachel Reeves reaffirmed the government's support for the development of open banking - signalling alignment between regulators and industry. For all these reasons, we're working with partners across the financial ecosystem to unlock the full potential of open banking. We've developed open-access A2A capabilities that support both consumer and business use cases - offering trusted, secure rails that complement card and other payment options. But we're not here to go it alone. We want to work with industry and policymakers to ensure that open banking delivers on its promise - for everyone.
