The Up&Up Group on the hidden cost of AI

Companies large and small are pouring capital into AI projects, chasing the promise of efficiency, speed and scale. But as Jason Harrison, chief operating officer of The Up&Up Group, argues in this episode of TechCentral’s TCS+, the upfront price tag tells only a fraction of the story – and many South African boards are signing cheques without fully understanding what they’re buying. Harrison uses The Up&Up Group’s own experience in experimenting with and implementing AI to glean insight into the gap between the large promises by the technology (and its Silicon Valley pundits) and harsh realities of stalling projects in enterprises, especially at the integration layer. The conversation digs into the costs that rarely make it into a chief financial officer’s spreadsheet: • Policy and governance, Harrison argues, are not soft considerations – they are line items, often substantial ones. • The costs of error: the reputational damage, financial exposure and legal risk when copyrighted material slips into outputs or autonomous agents go off-script. • Agents that run amok, with companies then only discovering the problem once the cloud bill lands. Beyond the balance sheet, Harrison flags AI’s energy footprint as a societal cost the industry is still reckoning with. AI adoption is accelerating despite these risks and Harrison describes the current moment as a kind of nuclear arms race, driven by share-price pressure and a deep fear of being last. Much of today’s AI spend, he suggests, is Fomo (“fear of missing out”) dressed up as strategy. For tech leaders trying to make sober decisions inside a hype cycle, separating signal from noise has become a leadership skill in its own right, he says. Suggested solutions include a “test and learn” philosophy where many small, inexpensive AI experiments are run throughout an organisation before viable instances are scaled appropriately. Harrison cautions against one-size-fits-all deployments and argues that governance must sit close to the work rather than only in the boardroom. Quarter-to-quarter measurable objectives matter, he says, but only if they live inside a long-term strategy. Despite his sober-minded view on AI’s high costs, Harrison still has an optimistic perspective on the technology and its potential to transform society, especially on the African continent. While the developed world is using AI to get answers, Harrison suggests African organisations may end up using it to learn how to think – a subtle but important distinction, and a timely note for any leader weighing their next AI investment.

The retirement decision most South Africans get wrong

What happens to your retirement savings when you leave an employer is one of the most consequential financial decisions most South Africans will make – and one of the most commonly mishandled. In this podcast conversation with Mpho Chitapi, 10X Investments senior investment consultant Michael Rossouw sets out what should happen, what often does, and where the costs lie. When an employee resigns, their pension or provident fund does not automatically follow them. Money is frequently left behind in an old employer fund by default, or withdrawn in cash during the transition. The cash option is the most damaging. Rossouw cautions against it not because the money is needed less in the short term, but because removing capital interrupts compounding in a way that is extremely difficult to recover from later, even on higher future earnings. A point Rossouw made bluntly is worth restating, because it is widely misunderstood: under the Pension Funds Act, individuals do not own pension or provident funds. Only a company can establish one, and employees are members of an employer-sponsored fund rather than owners of it. When the employment ends, the relationship with the fund changes, too. What individuals can own are retirement annuities and preservation funds. A preservation fund is the vehicle into which an employee can transfer their accumulated retirement savings when they leave a job, taking direct control of how the money is invested and what they pay to have it managed. That control matters. A preservation fund lets the holder choose an asset allocation aligned to their risk profile and time horizon, and integrates with a retirement annuity or a new employer fund as part of a single retirement plan. Leaving money behind in an old employer fund offers none of those advantages. Rossouw’s sharpest warning is on fees. Even a well-structured retirement plan can be quietly undermined by costs that compound in the same way returns do – only in the wrong direction. He urged savers to interrogate the effective annual cost (EAC) of any product they sign on for. A 1.5 percentage point difference in annual fees sounds modest, but compounded over a working lifetime it can erode a meaningful share of an eventual retirement balance. Higher fees are not always justified by better performance, Rossouw says, and savers should be especially cautious about committing to high-cost products on long contracts. He is more measured on the role of online calculators and AI-powered tools, which have made it easier than ever for individuals to model their own retirement scenarios. The tools are useful, he says, but their inputs and assumptions need to be checked carefully – and outputs interrogated rather than accepted at face value. The underlying message is straightforward. Retirement planning when changing jobs does not require expertise. It requires attention, an understanding of the available vehicles and a clear-eyed view of what fees will cost over time. The decision made at the point of resignation – leave it, transfer it or cash it out – is one of the most consequential a person makes for their own future self. It is, ultimately, your money.

‘The ISP for ISPs’: Vox’s shift to wholesale aggregator

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.

Vodacom Business moves to crack the SME tech gap

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

Arctic Wolf unpacks the evolving threat landscape for SA businesses

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.

Vox Kiwi: a wireless solution promising a fibre-like experience

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.

Flipping the narrative on AI in the Global South

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.

Cloud On Demand and Consnet: inside a real-world AWS partner success story

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.

Why cybersecurity is becoming a competitive advantage for SA businesses

Cybersecurity is undergoing a quiet but important shift in South African boardrooms: from a defensive cost centre to a strategic business enabler. That was the central theme of a recent TechCentral TCS+ podcast discussion featuring Vodacom Business acting executive head for cloud security Lukhanyo Zahela and KnowBe4 Africa senior vice-president for content strategy Anna Collard. Once seen primarily as an IT problem, cybersecurity is now recognised as a material business risk with direct financial, operational and reputational consequences. But the discussion made clear that security, done well, can also signal organisational maturity to regulators, investors and partners – and increasingly, become a source of competitive advantage. Collard likened strong security controls to having “good brakes on a fast car”. Without them, businesses cannot safely deploy emerging technologies such as artificial intelligence or scale digital platforms with confidence. Availability and resilience, she argued, are foundational: “Businesses are in business to stay in business.” That foundation is under growing pressure. Zahela said South Africa’s threat landscape is evolving rapidly, driven by a criminal ecosystem that is itself adopting automation and AI. Phishing attacks have become far more convincing, while ransomware continues to disrupt cloud migrations, often exploiting misconfigured environments rushed into production. Defenders, however, are also using AI. Vodacom Business has integrated AI-driven detection and response into its managed security services, reducing the time taken to detect and respond to threats from hours to minutes, or even seconds. Crucially, these systems are adaptive, learning continuously from global threat intelligence rather than relying on static rules. Despite advances in automation, human behaviour remains central to security outcomes. Many breaches still involve simple mistakes. Collard argued that well-trained employees can act as an extension of the security function, providing judgment and context that AI cannot. The challenge is that organisations must now secure not only people, but also the AI tools and agents they use – all of which can themselves be manipulated. This requires what Collard described as “digital mindfulness”: a security-aware culture led from the top. Executives must model good behaviour, while organisations adopt zero-trust principles that continuously verify identity and access rights across employees, partners and devices, enforcing least-privilege access by default. To turn security into an enabler rather than a blocker, it must be embedded from the start. “Security by design” – integrating safeguards into systems, processes and digital initiatives upfront – avoids costly retrofits later and allows innovation to move faster with clearer risk boundaries. The payoff can be tangible. A strong security posture can reduce cyber-insurance costs, improve business continuity and prevent expensive operational disruptions. More broadly, trust built through resilience and good governance can attract customers, partners and investors. The key message for business leaders, the speakers agreed, is to stop treating security as reactive. The more powerful question is no longer, “How do we protect what we have?”, but rather, “How does security enable us to do what we couldn’t do before?” Don’t miss this important conversation!
