Security now one of the UK’s fastest-growing career paths | Computer Weekly


Cyber security is now the UK’s fifth fastest-growing profession, with the number of people working in the field having almost trebled since 2021 to 83,700, according to an analysis of more than 400 occupations tracked by the Office for National Statistics.

The analysis was conducted by managed security services provider Socura, which claimed this means there are now more cyber professionals than there are architects, bricklayers, farm workers, armed forces officers and vets – and there is now one cyber security pro for every 68 businesses in the country, up from one per 196 just five years ago.

Socura CEO Andrew Kays said the figures demonstrated that security is far from a niche industry, and has instead become a cornerstone of the British economy.

“AI may be changing the landscape, but skilled professionals are still the front line of our national defence,” said Kays. “For the UK to remain a global leader in online safety, we must ensure that we continue to develop talent with the skills needed to keep pace with modern threats and that a career in cyber is accessible to everyone.”

Yulia Cherdantseva, a reader at Cardiff University’s School of Computer Science & Informatics and director of its Academic Centre of Excellence in Cyber Security, said that in spite of the “extraordinary growth”, there was still a lot more to be done to address persistent skills gaps in the security profession.

She pointed to a need to better align academia, certification bodies and the industry itself, on areas such as training and qualifications, standardised language in job descriptions and pathways that support global mobility.

“The need for a structured knowledge framework that addresses emerging cyber security concerns in a timely manner and provides clear guidance to the community is critical,” said Cherdantseva. “Frameworks such as CyBOK exemplify this approach by offering a foundation that underpins university degree programmes, professional certifications and assured training led by the NCSC.”

An imbalanced picture

Despite the impressive top-line growth, it is important to note that the total number of cyber professionals is still a fraction of the number of active programmers and software developers, whose number exceeds 500,000 in the UK. Security workers are also outnumbered by IT directors and managers, IT business analysts, architects and system designers, IT project managers and IT user support technicians.

The data also revealed significant regional imbalances, with most security workers based around London and in South East England, followed by North West England.

And nor has much progress been made since 2021 on addressing the gender gap in security. Even though the number of women working in the sector has also more than doubled over the same period, barely 20% of cyber professionals are female, and the numbers have hovered around this point for years. This trend is reflected in the wider IT industry, where the number of women in the workforce continues to grow at a snail’s pace.

Reflecting on this, Clare Johnson, founder of Women in Cyber Unlimited, said: “It is disappointing that gender diversity in the sector remains fairly static, with women making up just over 20% of the cyber security workforce. Initiatives such as the CyberFirst Girls competition and the increasing number of “women in cyber” networks are important in addressing this imbalance. 

“Providing a platform for women to showcase their skills and meet other women, alongside being visible role models, all helps to raise awareness of the importance of diversity. The more brilliant minds we have working on cyber security challenges, the more resilient we will all be,” said Johnson.

Tata Communications unveils self-healing network | Computer Weekly

Tata Communications unveils self-healing network | Computer Weekly


Tata Communications has launched a self-healing network platform called IZO datacentre Dynamic Connectivity, which is designed to eliminate costly datacentre downtime and support the demands of an artificial intelligence (AI)-driven world.

In explaining the rationale for the launch, Tata Communications said that in the current digital economy, disruptions from cable cuts, route failures or sudden AI workload spikes can bring business to a standstill.

Specifically, that is every enterprise depends on the ability to always be connected with an uninterrupted data flow. From financial transactions, information technology-enabled services (IT-ITeS) and manufacturing to streaming platforms and online retail, the connections between datacentres keep the modern world running. Tata Communications added that when those connections are interrupted, businesses do not just slow down, they are brought to a complete standstill.

The company warned that the networks connecting many enterprise datacentres were built for a different era. Traditional datacentre (DC)-to-DC links were designed for predictable workloads and stable traffic patterns. It stressed that the current reality is far more dynamic. In this, enterprises operate across global locations and cloud environments, moving massive volumes of data in real time to support AI workloads and business needs.

In an environment shaped by increasing geopolitical constraints, cable outages, route failures or sudden spikes in demand, these can quickly cascade into service disruption and operational risk, leading to a costly downtime. In such scenarios, the response is often reactive and manual, consuming valuable time when business need certainty and speed.

The IZO datacentre Dynamic Connectivity platform is designed to address these issues by creating an intelligent network that covers key global datacentres across five continents. 

Tata Communications, said that unlike conventional architectures, the new platform uses deterministic multi-path routing to deliver predictable latency and performance. It said this transforms resilience from a reactive process into an autonomous capability, changing how enterprises connect their datacentres in an increasing AI-driven and distributed world. 

This means the platform is smart enough to automatically re-route traffic within seconds without manual intervention during disruptions. This is said to enable enterprises to achieve >99.99% service availability across mission-critical infrastructure that supports business-critical applications, “turning resilience from a contingency into a default state”.

The platform is also attributed with giving enterprises access over their connectivity. Through a unified digital interface and APIs, enterprises can monitor performance, receive proactive alerts and dynamically scale bandwidth as workloads evolve.

Tata Communications said the result is that business impact is a shift from crisis management to strategic growth with business leaders no longer having to guess their future needs or over-pay for “just in case” bandwidth. Instead, leaders have access to Al-driven predictive insights allowing them to forecast their capacity requirements in advance. If a sudden workload demands more capacity or choice of route, users can instantly scale their bandwidth or add route through self-service feature.

Tata Communications calculates that by moving to a flexible, consumption-based pricing model, enterprises can reduce the need for idle backup capacity and save up to 30% on operational costs. Enterprises can activate resilience and bandwidth when required, helping to optimise costs while maintaining deterministic performance across geographies.

“Datacentres are the core engines of today’s digital economy, and the connections between them must be as resilient as the networks that connect them,” said Genius Wong, chief technology officer and executive vice-president of core and next-gen connectivity services at Tata Communications. “They must be just as dynamic as the applications they support.

“With IZO DC Dynamic Connectivity, we are shifting resilience from a reactive process to an autonomous capability. By combining global reach, deterministic routing and intelligent automation, we are enabling enterprises to build a digital foundation that scales with confidence and operates without disruption.”

Can a Home Appliance Fix the Problem of Soft-Plastic Waste?

Can a Home Appliance Fix the Problem of Soft-Plastic Waste?


Soft plastics are notorious for jamming sorting machines, slipping through processing lines, and wreaking havoc on the environment. They’re also not accepted in most municipal curbside recycling programs.

Facilities for recycling these types of plastic exist, but getting waste to these locations clean and free of what some call “wishful recycling” items (compostable cups, plastic utensils) is such a challenge that the majority of soft plastics, even the bags recycled at the front of grocery stores, end up in the trash. The SPC is what Arbouzov calls a “pre-recycling device,” designed to simplify this stream and deliver plastic that’s contained, traceable, and more likely to make it through the system.

I tried to envision how the blocks would turn into patio furniture, as advertised, but didn’t learn exactly how until months later, when Arbouzov sent me a video of the blocks at their final destination—a facility in Frankfort, Indiana, that specializes in processing polyethylene and polypropylene films. The blocks get shredded into crumbles resembling, at least on video, handfuls of wet newspaper, which are then compressed into composite decking, chairs, garden edging, and more.

“The full cycle from mailing a block to it entering recycling processing typically takes a few weeks,” Arbouzov said, “depending on shipping time and batching schedules.” Right now, the Frankfort location is the only facility processing the blocks, but Arbouzov said he hopes this is only temporary.

“Our goal is to shift more of this processing closer to where the material is generated, so blocks can move in bulk through regional recycling infrastructure rather than through mail-based logistics,” he said. “The mail-back system is essentially a bridge that allows the material to be captured today while that larger infrastructure develops.”

Recycling, Rewired

I found that my household of three was able to produce a block every couple of weeks, which quickly outpaced the provided supply of mailers. As the blocks started piling up on the floor of my office, I found myself wishing the SPC made something useful for consumers. Spoons, straws, 3D-printing filament … anything that could be used at home.

However, a 2023 Greenpeace report found that recycling plastic can actually make it even more toxic than it already is—heating it can not only cause existing chemicals to escape into the air and water supply, but even create new ones, like benzene. Would I want this in my house? Does recycled plastic actually belong in a circular economy? I asked Arbouzov what he thought.

Can Modular Phone Accessories Finally Evolve Beyond MagSafe?

Can Modular Phone Accessories Finally Evolve Beyond MagSafe?


Predating the launch of Moto Mods in 2016, the first batch of Jolla The Other Half concepts included back covers with an extra E Ink display, an infrared camera, and an Angry Birds tie-in that activated themes and ringtones. But probably the most popular was a Blackberry/Nokia Communicator-style slider keyboard made and sold by two entrepreneurs from the original Jolla community. That trend is back in—at CES 2026, accessory company Clicks showed off a magnetic keyboard accessory you can slap on the back of any Qi2 or MagSafe smartphone, though it uses Bluetooth for connectivity.

Quite a bit has changed in what’s achievable, not least more bandwidth, more capability, and more accessible, high-quality 3D printing. “We have seven pogo pins [on the Jolla Phone] which give you the capability to get power out and power in,” says Jolla CEO Sami Pienimäki. “So you can do maybe wireless charging, and you can power external circuit boards.” Pienimäki imagines E Ink interfaces or low-bandwidth radios on the back of its upcoming phone—it has an I3C interface, which delivers bit rates up to 12 megabits per second, allowing data to flow between the phone and the mod, enabling new kinds of smarter modular accessories.

Jolla has promised to release the final phone specifications by the end of the month, with shipping due for the first preorder customers at the end of June. Pienimäki teases that it’s “tempting” for him to release one of Jolla’s own internal concepts for a TOH back cover even earlier as “a showcase of what you can actually do.” (The Jolla Phone doesn’t have FCC approval in the US, but the company is considering a US launch in the future.)

With more than 10,000 preorders since December 2025, Jolla is back in business but still far from mainstream. So why, despite plenty of internet hype over the years, did truly modular phones never quite take off?

“During the LTE days, there was thinking that these devices would morph into ‘cloud phones,’ where the rest of the phone could be cost-optimized,” Fieldhack says. “Swappable parts and lower costs, as most of the compute would be done in the cloud.”

But things changed as flagship phones went from costing $350 to around $1,000. Both the camera and media production and consumption became much more important: “Great displays, great cameras, multiple cameras, more memory, better sound and mics, as well as more elegant and thin devices—this is not easily done on a modular smartphone,” Fieldhack says. “There are huge compromises, and phones are thicker and heavier with less performance. Then, agentic AI, on-device for lower costs and better security, made modular design even less optimal.”

Repairable Modules

One strong and emerging argument for true hardware modularity is repairability. Another European smartphone maker, Fairphone, has been making that case for over a decade. “It’s about thinking about how do we group the actual phone itself into modules?” says Fairphone chief technology officer Chandler Hatton. The latest FairPhone Gen 6 smartphone is made up of 12 modules. A customer sitting at the kitchen table with a single T5 screwdriver (included) and a guitar pick can repair the phone quickly, easily, and cheaply.
