Vox, a well-established retail internet service provider is expanding its services to the wholesale market through aggregation. In this episode of TechCentral’s podcast series TCS+, Andre Eksteen, senior product manager for fibre to the business at Vox, discusses the rationale behind this strategy and the services Vox is offering as “the ISP for ISPs”. Eksteen delves into: • The thinking behind Vox’s move into the wholesale space; • The detail regarding Vox’s operating model as an aggregator with no physical infrastructure of its own; • The financial benefits ISPs derive from engage via an aggregator against connecting to a wholesaler themselves; • How aggregation services lower the operational burden on retail ISPs; • Vox’s white-labelling service and how wholesalers benefit from it; • The tooling Vox providers to help ISPs run their businesses more efficiently; • How Vox balances the potential internal conflict of interest arising from it being a retail competitor to the same ISPs to which it supplies wholesale services; and • The impact the existence of a wholesale aggregator like Vox will have on the retail ISP market.

The pace at which artificial intelligence is reshaping the threat landscape is outstripping the ability of most organisations to defend themselves, with shadow AI, synthetic identity attacks and a looming quantum computing disruption all converging at once. That’s the view of DataGroupIT CEO Werner Lindemann, who joined Duncan McLeod on the TechCentral Show to unpack what business leaders should be doing about AI and information security. Lindemann, who spent more than 30 years in senior roles at BCX and Clickatell before joining the security solutions distributor, says the African threat environment is no longer a watered-down version of what is happening elsewhere. Attackers are deploying the same AI-powered tools globally, and AI-enabled phishing campaigns now achieve click-through rates that traditional defences were never designed to withstand. A bigger blind spot, he argues, is shadow AI – employees pasting sensitive data into unapproved AI tools without oversight. Lindemann says this is fast eclipsing the shadow IT problem of the past decade because the tools are free, frictionless and often invisible to security teams. The conversation also tackles the credibility crisis facing identity verification. With AI now able to clone a CEO’s voice in real time or generate synthetic profiles that pass biometric checks, Lindemann believes traditional verification methods are fundamentally flawed. A big challenge is helping boards understand the issue in business rather than technical terms. Lindemann also weighs in on the rise of the chief AI officer role, following Sanlam’s recent appointment, and on whether African organisations are equipped to adopt AI at the pace global peers are setting given the continent’s acute skills shortage. The discussion closes on quantum computing. Lindemann challenges the conventional view that the quantum threat is a decade away, and outlines what business leaders should be doing now to prepare for the post-quantum cryptography world – even if the risk still feels distant.

Award-winning South African film director Donovan Marsh has pivoted to artificial intelligence filmmaking and believes generative AI tools could fundamentally reshape how movies are made – and who gets to make them. Marsh, whose 30-year career includes directing the Hollywood submarine thriller Hunter Killer starring Gerard Butler and Gary Oldman, the Spud films and iNumber Number, is the latest guest on the TechCentral Show. The economics, he tells TechCentral editor Duncan McLeod, are extraordinary: a single complex scene in a traditional production requires crews, equipment, locations and days of scheduling, while AI tools collapse much of that overhead into work that can be done at a desk. But Marsh is clear that the creative work has not disappeared. He still directs shot by shot, much as he would on a conventional set, and uses a patchwork of different AI tools – no single product yet does everything. He has found that simpler prompts produce better results, saying over-prescription tends to degrade output quality. Marsh acknowledges the disruption this implies for camera operators, lighting crews, set designers and extras. But he argues that AI filmmaking could prove liberating for smaller filmmaking markets like South Africa, where the budgets to make ambitious local movies have dwindled. He has co-founded Dragon Studios AI with Ronnie Apteker and Stephen Cholerton, and is developing what he believes will be among the first AI-generated feature films. The tools are not quite there yet for a full 90-minute production, he says, but the gap is closing fast. Marsh also weighs in on where the so-called “uncanny valley” still trips up generative video, the future of the acting profession and what AI filmmaking could look like by 2029. TechCentral

Everyone agrees that small and medium enterprises are the backbone of the South African economy. But the reality on the ground tells a different story – too many small businesses are still running on spreadsheets and WhatsApp, locked out of the tools that could help them compete. In this episode of TCS+, TechCentral editor Duncan McLeod is joined in-studio by two members of the recently established Vodacom Business advisory board: Sannesh Beharie, managing executive of SME and mobile products at Vodacom Business, and Andrew Fulton, co-founder of data analytics firm Eighty20, a Vodacom Business partner. Vodacom Business set up its advisory board last year to bridge the gap between enterprise-grade technology and the small businesses that need it most, bringing together tech leaders and external specialists to help companies – as well as SMEs – navigate digital transformation. In the conversation, McLeod, Beharie and Fulton dig into what’s actually stopping small businesses from going digital, whether bundled connectivity and cloud offerings are genuinely good for SMEs or just a polite way of locking them in, and where AI fits into the picture for a 20-person business in South Africa. They also tackle how Vodacom Business positions itself against the likes of AWS, Google and Microsoft in the SME market, where a small business owner should spend their first R10 000 a month on tech, and the most common mistakes SMEs make when they do invest in technology. Don't miss the discussion on what a genuinely SME-first solution looks like – and whether the tech industry is guilty of designing for corporates and simply shrinking solutions down for smaller businesses. * TCS+ episodes are sponsored by the party concerned TechCentral

MTN South Africa has launched Pi, a digital-only mobile operator that runs on MTN’s network but operates as a standalone brand, offering contract-free mobile and home 5G connectivity through a single app, with no call centres, no credit checks and no lock-in. In this episode of the TechCentral Show, TechCentral editor Duncan McLeod talks to Divyesh Joshi, chief commercial officer at MTN South Africa, about the thinking behind the launch and what it signals about the direction of the local telecommunications market. Pi’s pricing is aggressive: R79/month for 500 voice minutes and R199/month for 20GB of mobile data, for example, alongside home fixed-wireless broadband plans. McLeod asks whether Pi is essentially MTN’s fightback against Telkom, which has been quietly gaining prepaid market share with competitive data pricing – and whether the launch is also a response to mobile virtual network operators like Melon Mobile. The conversation explores what Pi means for MTN’s margins, particularly on voice, and whether the aggressive pricing on calls is an admission that voice has become a commodity in a market where many consumers have shifted to WhatsApp for calls. McLeod also asks whether Pi represents MTN’s attempt to get ahead of a structural shift in how people consume telecoms services – drawing a parallel with MultiChoice’s failure to adapt quickly enough to changing market demands in the video entertainment space. A key question is what happens to MTN’s existing SuperFlex product, which targets a similar customer base. Is Pi going to cannibalise MTN’s own subscribers? Finally, McLeod and Joshi discuss MTN’s new eSim-based roaming deals, which offer data at R12/GB in markets like China and France – though curiously, roaming in eSwatini, where MTN has a subsidiary, costs R85/GB.

The South African Post Office has been in business rescue – a form of bankruptcy protection – since July 2023. Business rescue practitioners Anoosh Rooplal and Juanito Damons have made it clear to parliament that the entity will not survive liquidation unless a R3.8-billion bailout is received soon. With some 5 500 jobs on the line, the big question is: is the Post Office worth saving? Rooplal spoke to TechCentral’s Nathi Ndlovu and was asked that question. In this episode of the TechCentral Show, Rooplal talks about: • The case for the bailout: The business rescue practitioners have already received R2.4-billion from government, while bailouts for the Post Office over the past decade amount to nearly R10-billion. Rooplal attempts to answer why this latest funding request is worth it. • The current state of the Post Office: Rooplal outlines what the R2.4-billion tranche was used for and what the R3.8-billion request would do, if provided. He also details what the future state of the entity might look like and how, without much in terms of income, salaries are currently being paid. • The need for a state-owned postal service: Even if national treasury were to agree to save the Post Office, does it have a place in a modern digital economy? • External funding and asset sales: If the business case for the Post Office’s revival is so strong, why have the businesses rescue practitioners not sold or rationalised assets or gone to the open market for funding? • Social grants and Post Bank: Rooplal explains what would happen to the many grant recipients processed via the Post Office should it not survive business rescue. • Private sector partnerships: The department of communications & digital technologies in November issued a request for information seeking private sector partnership proposals. Rooplal explains the “chicken and egg” problem at the core those discussions. • No more options: Chapter 6 of the Companies Act compels business rescue practitioners to file for liquidation if they see “no reasonable prospect” of rescue. Rooplal explains why he and his associate, Damons, are close to pulling the trigger. Don’t miss the discussion! TechCentral

Anton Fatti, chief technology officer of HealthBridge, says the doctor-patient relationship must remain at the centre of digital transformation in healthcare, even as AI reshapes how medical practices operate. Speaking on TechCentral’s Meet the CIO podcast series, brought to you by NTT DATA, Fatti said AI and cloud computing are already easing the administrative burden on doctors and medical professionals, allowing them to spend more time with patients rather than on paperwork and back-office tasks. Fatti joined Healthbridge as CTO in February 2025, bringing experience from senior technology leadership roles at the South African Revenue Service, where he served as chief technology and innovation officer, as well as at Discovery, where he was chief digital officer, and data business Lightstone, where he was CIO. Healthbridge, founded in 1999, positions itself as a technology partner that helps medical professionals run their practices so they can focus on patient care. The company’s offerings have evolved significantly since its early days – from a pre-cloud, pre-AI era to a modern cloud-based software-as-a-service platform built in partnership with Google Cloud. In the interview, Fatti discusses how the company has structured its innovation efforts. He also addresses which parts of clinical workflows are ready for AI automation today and which must remain human-led, and how far the industry is from AI playing a decisive role in diagnosis. On the shortage of medical professionals in South Africa, particularly in certain specialities, Fatti explores how AI and other modern tools can make doctors more productive – and whether practitioners are receptive to adopting them. He also shares his views on how policymakers should be thinking about AI in healthcare, the new skills emerging inside his teams and his approach to disrupting Healthbridge’s own business model before a competitor does.

Most security teams can tell you what they've deployed. Far fewer can answer the board's next question: are we actually less exposed than we were three months ago? In many organisations, the gap between security activity and real risk reduction remains stubbornly wide, even as threats become faster, more adaptive and harder to spot. In this episode of TCS+, Clare Loveridge and Jason Oehley from Arctic Wolf unpack what the 2026 Arctic Wolf Threat Report reveals about how the risk landscape is shifting, both globally and in South Africa. They discuss whether organisations are genuinely becoming more proactive, how AI is changing the game for attackers and defenders alike, and why familiar blockers continue to undermine even well-funded security programmes. The conversation also explores what it means to "end cyber risk" in practical terms, why continuous improvement matters more than one-off projects, and how organisations should think about residual risk — the portion that remains even after controls are in place. The episode closes with a look at Arctic Wolf's cybersecurity warranty in South Africa and what role warranties can play in risk management when prevention alone is not enough. TechCentral

Access to stable, reliable, high-speed internet is crucial to participating in the modern economy. Although fibre connectivity offers the highest speeds and reliability, fibre penetration rates unfortunately remain relatively low in South Africa, leaving may would-be customers wanting. Vox recently launched Kiwi, a wireless connectivity solution promising a fibre-like experience with speeds of up to 200Mbit/s. In this episode of TechCentral’s TCS+, Theo van Zyl, head of wireless at Vox, provides more details about the Kiwi service and how it works. Van Zyl delves into: * The rationale behind building a wireless service that offer a fibre-like experience; * Why customers should choose Kiwi over a 4G or 5G fixed-wireless solution; * The technical innovations Vox took advantage of to get the speed and reliability Kiwi offers its customers; * How Kiwi behaves in disruptive scenarios such as thunderstorms; * The various tiers customers can subscribe to and the speeds they offer; * The kind of spectrum Kiwi uses and how it does so efficiently; * The installation process and the hardware involved; and * Why the name Kiwi was chosen and its relevance to wireless technology.

In this thought-provoking episode of TechCentral's TCS+, Mpho Chitapi sits down with Dr Josefin Rosén, principal trustworthy AI specialist in SAS's Data Ethics Practice and co-author of the influential report Constraint to Capability: Flipping the Narrative on AI in the Global South. What unfolds is a rich conversation that challenges long-held assumptions about Africa's role in the global AI ecosystem — and reframes governance, ethics and constraint not as obstacles but as strategic advantages. The discussion explores how deeply regulated environments sharpen one's appreciation for integrity, accountability and human impact — principles that are now indispensable in the design of trustworthy AI systems. This sets the tone for a broader conversation on why governance-by-design, representative data and bias mitigation are not "nice-to-haves" but foundational to sustainable AI adoption, particularly for public-facing systems operating in diverse and unequal societies. A central theme is "flipping the narrative" — moving away from the idea that the Global South must simply catch up, and instead recognising its unique opportunity to shape AI differently. Rosén offers compelling insights into Africa's position as the youngest continent, cautioning that demographic advantage alone does not automatically translate into leadership. The discussion interrogates what must change — across policy, education, data strategy and governance — for Africa's youth dividend to become real AI leadership, and why the window to do so is open but narrow. Listeners are taken deeper into Africa's distinct AI opportunity set: smaller, more context-specific language models; mobile-first innovation; and the potential to build systems that are locally relevant, linguistically inclusive and ethically grounded from inception. Rosén underscores that when AI systems — especially those interfacing directly with the public — are not sufficiently representative of the people and environments they serve, trust erodes quickly. Integrity, reliability and contextual relevance are therefore not abstract principles but practical necessities for AI systems that aim to endure and scale responsibly. The episode closes by exploring practical use cases and forward-looking responsibilities, asking who must do what next — from policymakers and universities to business leaders and technologists — if Africa is to seize this moment. The conversation leaves listeners with a powerful message: the future of AI in the Global South will not be determined by scale alone but by the choices made now around governance, representation and trust.

Artificial intelligence isn’t just changing how work gets done, it’s rewriting the rules of business. Organisations are scrambling to redefine processes and job descriptions, while employees are grappling with new tools and new ways of thinking that are transforming the way they approach their daily tasks. In this episode of the TechCentral Show, Antony Makins, acting CEO at TForge and chair of the special group on AI and robotics at the Institute of IT Professionals South Africa, unpacks the skills revolution unfolding alongside the AI one. Makins delves into the patterns emerging across organisations and the broader labour market as AI adoption accelerates. He also explores the mindset shift it’s imposing on the workforce, and which roles are being hit hardest by AI-driven changes to how we work. He delves into the opportunities that exist despite the very real threat AI poses to jobs – and what government can do to create an enabling environment for workers to adapt to a labour market increasingly shaped by AI, machine learning and data analysis.

Safety is a core concern for e-hailing operators as it ensures that platforms engender trust among drivers, passengers and the general public. Bolt recently commissioned market research firm Ipsos to conduct research into the perceptions of rider safety in South Africa's e-hailing market. In this episode of TechCentral's TCS+, Simo Kalajdzic, senior operations manager at Bolt South Africa, discusses findings from the report and how Bolt has used them to inform decision-making regarding its approach to safety on its platform. Kalajdzic delves into: * The rationale behind Bolt's commission of the report; * Why market research firm Ipsos was chosen to conduct the research; * Key findings from the report and the products Bolt has developed using those insights; * The key drivers fuelling e-hailing adoption in South Africa and where safety ranks compared to other factors like reliability and cost; * Scenarios that lead to South African's choosing e-hailing over other transport types; * How e-hailing compares to other modes of transport in terms of safety perception; * What survey respondents said about e-hailing's impact on drunk driving in their respective cities; * Those features of e-hailing apps that make users feel safer compared to other types of transportation; and * What users can do to maximise their safety levels when using the platform.

Technology sits at the heart of modern capital markets, and nowhere is that more evident than at the JSE. In the latest episode of Meet the CIO, TechCentral editor Duncan McLeod sits down with Tebalo Tsoaeli, the bourse’s CIO, to unpack how technology underpins Africa’s largest stock exchange – and how it is evolving for a more digital, global and real-time future. Meet the CIO is brought to you by NTT DATA, where global experience meets local impact. Tsoaeli has spent his entire career in financial services technology, starting out as an application developer at Rand Merchant Bank before holding senior technology roles at Standard Bank, Investec, Nedbank, FirstRand and Sanlam. He became CIO of the JSE three years ago, bringing deep experience in large-scale, mission-critical systems to one of the most tightly regulated technology environments in the country. In the conversation, Tsoaeli reflects on his early exposure to computing and how a formal grounding in computer science shaped his career path. While he is clearly a technologist at heart, he explains how his role has evolved beyond pure IT delivery to focus on strategy, resilience, regulatory compliance and enabling market growth. A major theme of the discussion is the JSE’s technology stack and how it has changed over time. Tsoaeli explains how the exchange now works closely with Amazon Web Services, moving away from a purely on-premises model to leverage cloud infrastructure for scalability, resilience and performance. He also addresses the question many market participants ask: can the cloud really be trusted with mission-critical exchange workloads, especially in a world where outages at global providers can have far-reaching consequences? Latency and real-time trading are central concerns for any exchange, and Tsoaeli provides insight into how the JSE’s infrastructure supports the full trading lifecycle – from pre-market activity through live trading to post-trade clearing and settlement. He also touches on the exchange’s networking architecture and how it is designed to deliver predictable, low-latency performance for brokers and market participants. The episode also explores the JSE’s strategic technology partnership with Nasdaq. Tsoaeli explains how this relationship operates at a technology level and what it has delivered so far, including support for market modernisation and international interoperability. Closely linked to this is the modernisation of the JSE’s Broker Dealer Accounting system, a project Tsoaeli describes as critical to improving efficiency, resilience and future-readiness. Given the highly regulated nature of financial markets, security and compliance are never far from the conversation. Tsoaeli outlines how the JSE balances innovation with stringent regulatory requirements, and what this means for data protection, operational risk and trust in the market. Looking ahead, the discussion touches on cross-border capital flows, dual listings and the potential role of emerging technologies such as artificial intelligence and machine learning in trading and market operations – along with the risks that come with them. Finally, Tsoaeli shares his perspective on what success looks like for the JSE’s technology journey over the next three to five years, how he sees the role of the CIO evolving, and – in a lighter moment – his favourite productivity hack.

The cloud revolution has challenged businesses of all sizes by changing how IT teams go about implementing projects and managing infrastructure. IT service firms have been doubly challenged, having to sell a new computing paradigm to their clients while also practising what they preach and adopting cloud-first technologies in-house. Consnet is an IT solutions firm that leveraged the Amazon Web Services distribution model to accelerate its own journey into the cloud, enabling the company to do the same for its customers. In this episode of TCS+, Dion Kalicharan, MD at Consnet, and Xhenia Rhode, AWS partner development manager at Cloud On Demand, speak about the benefits of leveraging the support structures in the AWS partner network. Rhode and Kalicharan delve into: • What the AWS distribution model is and how it benefits partners in the ecosystem; • Consnet’s 21-year history, the services it provides and how its journey into the cloud began; • How Consnet being supported by Cloud On Demand gave it the know-how to support its own customers on their cloud adoption journeys; • The technical and training support that helped guide Consnet to upskill its teams and gain cloud expertise; • How Cloud On Demand “marked Consnet’s homework” by double-checking the quality and efficiency of its cloud deployments; and • How Cloud on Demand strategically meets its partners where their needs are.

TechCentral’s electric car show Watts & Wheels is back for episode 3 of season 1, and while EVs remain the focus, the conversation takes a detour into something far less planet-friendly – and far more jaw-dropping. Duncan McLeod and co-host William Kelly kick off by drooling over a wild new Toyota performance machine they say is real, street legal and due in 2027. It’s a 4l hybrid V8, rear-wheel drive “hypercar” with supercar proportions and serious numbers: 478kW and a quoted top speed of 320km/h or more. It’s the sort of car that feels entirely out of character for Toyota – and that’s exactly why they can’t stop talking about it. From there, the conversation swings hard in the other direction: the all-electric Porsche Cayenne, which is shaping up as a huge statement from Stuttgart. The hosts discuss its performance claims – including a 0-100km/h sprint in the mid-2s range – and a range figure north of 600km. They also debate the realities of EV depreciation and whether buyer anxiety around battery longevity is starting to fade as real-world data shows high-mileage EVs retaining strong battery health. The episode then turns to Ford CEO Jim Farley’s candid admission that big, expensive EV trucks haven’t delivered as hoped – and why legacy car makers may need to refocus on smaller, more affordable models. The discussion touches on Ford’s partnership with Renault on EVs, and what that could mean for markets like South Africa. But the meatiest local segment is BYD’s push into South Africa with an aggressive product and charging strategy. William and Duncan unpack their impressions of the BYD Sealion 5 plug-in hybrid – positioned as a direct rival to the Toyota Corolla Cross – and criticise the lack of technical detail shared at its launch. They also discuss BYD’s planned roll-out of a major charging network, including megawatt-scale sites, and what that could mean for shrinking range anxiety. The episode closes with the show’s “Hot or Not” segment – and one clear takeaway: 2026 is shaping up as a pivotal year for electrification, even as petrolhead fantasies refuse to die.
