    Octotel’s Trevor van Zyl on the fibre merger question

    2026/09/16 | 25 mins.
    Octotel CEO Trevor van Zyl joins the TechCentral Show to talk about where South Africa’s fibre market goes next – including a potential merger with MetroFibre Networx. Van Zyl told TechCentral that Octotel and MetroFibre Networx are assessing a combination that would create the country’s third-largest fibre network operator, with both companies sitting under a common investor in an AIIM-led consortium.

    In the interview, he sets out Octotel’s position: just under 400 000 homes passed across the Cape Town metropole, the West Coast and the Garden Route; a balance sheet he says lets the company deploy capital when and where it chooses; and a Western Cape footprint he argues overlaps very little with MetroFibre’s.

    He discusses the next phase of roll-out, too. As networks push into lower-LSM areas, “the commercials and the economics start changing”, he says, and affordability now reaches well into the middle class.

    He rejects the idea that fixed-wireless access can substitute for fibre in dense settlements – wireless has improved dramatically, he says, “but when you look at the actual demand case and what is required in those environments, it absolutely has to be fibre”. The more important question, in his view, is how to distribute it economically once you get there.

    On Openserve’s move into the ISP business, Van Zyl is relaxed. He says he understands why Openserve did it, but that Octotel will not follow: “We certainly don’t want to become an ISP. We’re not good at being an ISP.”

    He also expects consolidation among ISPs as networks saturate, sees low-Earth orbit satellite as complementary to fibre rather than a threat to it, and will not rule Octotel out of any future move by MTN on fibre network assets.

    Herotel CEO Van Zyl Botha on beating Starlink to South Africa

    2026/08/14 | 22 mins.
    Amazon’s Leo satellite constellation is coming to South Africa in 2027 through Herotel. TechCentral deputy editor Fanie van Rooyen speaks to Herotel CEO Van Zyl Botha about Evry, the brand that will sell Amazon Leo to South African homes, and about how a company with no local licence walked into a market that has kept Starlink out for years.

    Botha explains why low-Earth orbit satellite technology changes the equation for anyone living beyond the reach of fibre and fixed-wireless services.

    He addresses the awkward questions directly:

    • How does Amazon get in without giving up 30%?

    • Does a wholesale-retail split leave anything behind in the country?

    • Would he sign the same deal with Starlink tomorrow?

    • What about the regulatory asymmetry?

    Also covered: what Evry is likely to cost; why studies on the market’s size range from 480 000 to 2.4 million potential customers; why Herotel is taking registrations for a service that has not launched commercially anywhere; whether Evry will cannibalise Herotel’s own fibre and wireless base; what Vodacom’s stake in Maziv means for Herotel’s independence; and why LEO satellites are viable now when the idea is 40 years old.

    Money just became native to the internet - Steven Boykey Sidley

    2026/08/12 | 45 mins.
    Steven Boykey Sidley has been a chief technology officer at a Fortune 500 company, a private equity investor, a videogame designer, a jazz musician and, for the past four years, a professor of practice at the University of Johannesburg. He is a partner at Bridge Capital, heading its futures advisory, and the author of eight books – two of them on bitcoin and crypto – with another due in October.

    TechCentral deputy editor Fanie van Rooyen spoke to him about the moment money finally became native to the internet, why the South African Reserve Bank appears to be walking in the opposite direction, and what AI is quietly doing to science and schooling while everyone argues about chatbots.

    TCS+ | Specops' Darren James on continuous trust in an AI world

    2026/08/07 | 45 mins.
    Specops Software’s Darren James explains why identity checks alone no longer stop determined attackers.

    Traditional approaches to access security no longer hold up in hybrid, cloud-first environments – and AI is widening the gap.

    In this episode, host Kevin Smith speaks to Darren James, senior product manager at Specops Software, about the distance between how organisations secure access and how people actually work.

    Businesses have poured money into identity-based controls – passwords, multi-factor authentication, zero-trust initiatives – yet breaches keep rising, because attackers increasingly exploit trusted identities rather than technical vulnerabilities. An intruder holding legitimate credentials looks like an authorised user and can operate undetected.

    That points to a shift in security thinking: verifying the user’s identity is no longer enough. Access decisions must also account for the device being used, its security posture and whether trust should hold for the length of a session.

    Working through a real-world breach, James shows how a single compromised account escalates into a serious incident, and where a more contextual approach to access control could break the attack chain before damage is done. The discussion reframes zero trust as an ongoing process rather than a one-time authentication event, and makes the case for layered verification.

    He also looks ahead to automated attacks and the rise of non-human identities – service accounts and AI agents among them. As organisations lean harder on autonomous systems, identity-centric models will face pressures they were never designed for.

    The executive takeaway is this: the cybersecurity battleground is shifting from identity verification to continuous trust. In an era of AI-driven threats and hybrid work, organisations need to stop asking “who is accessing the system?” and start asking, continuously, “should this access still be trusted?”

    TCS+ | Why South African workers must become supervisors of digital labour

    2026/07/31 | 43 mins.
    ADG’s Cliff de Wit on why the next management challenge is overseeing teams of autonomous software agents.

    Not long ago, organisations were experimenting with generative AI to draft e-mails, summarise documents and answer questions. Today agentic AI is changing what the technology is for.

    In a conversation on TechCentral’s TCS+ podcast, Cliff de Wit, MD for South Africa and group chief innovation officer at Accelera Digital Group (ADG), argued that the real story is not machines replacing people but a fundamental shift in how work gets done — and where humans create value.

    Rather than completing individual tasks on command, AI agents can be given an objective and left to determine how best to achieve it. De Wit illustrated this with a know-your-customer (KYC) use case in which agentic AI is already automating complex workflows and accelerating business outcomes.

    AI is no longer simply a tool that assists workers. Increasingly, it is a digital workforce in its own right.

    In a country with one of the world's highest youth unemployment rates, concerns about automation are understandable. But De Wit challenges the idea that AI should be viewed purely as a job-replacement technology.

    "The human skills involved in business are fundamentally changing, but the basics of business still remain," he said.

    Businesses will still need people to solve problems, exercise judgment, build relationships and drive innovation. What changes is how those outcomes are achieved: as routine and administrative work is automated, workers move up to activities where uniquely human skills matter most.

    The sharper risk is distributional. Without investment in education, training and digital skills, AI's productivity gains could widen existing inequalities — not because jobs disappear, but because opportunity concentrates among those who know how to work with the technology. AI literacy may soon matter to employability as much as computer literacy did during the digital revolution.

    Organisations are already deploying agents into operational environments, in some cases slotting them into workforce structures alongside human employees. Leaders are no longer managing only people; they are managing mixed teams.

    De Wit believes businesses are better prepared for this than they think. Companies have long used governance frameworks and risk controls to oversee human decision-making, and many of the same principles adapt to digital workers. Whether a decision is executed by a person or a system, accountability, escalation and oversight remain essential.

    Which decisions should be delegated, then, and which should stay under human control? De Wit's answer comes down to risk, and he sets out a framework for categorising it. The future, on his reading, is unlikely to be fully autonomous. Successful organisations will run human-in-the-loop models in which AI handles execution while people supply direction, judgment and accountability.

    De Wit is optimistic. Many local organisations are still experimenting, but a growing number are moving past pilots to solve real problems and generate measurable value.

    For leaders, the question is no longer whether to adopt AI, but how to do so responsibly, effectively and inclusively. The future workforce will consist neither solely of humans nor solely of machines — it will consist of humans who know how to lead, govern and orchestrate digital labour.

    And that future is arriving faster than many realise. Don’t miss a great discussion!
