We unpack the "web" approach to security, and why signal jamming is exactly the threat it's built for. Plus: a major SA tech distributor gets hit, what Investec pays to protect two executives, and the hidden inner workspace researchers just found inside an AI.

But first…

A spider web looks flimsy, but it survives anyway, and the reason is worth stealing…

Hit one strand and the web absorbs the shock; snap one and the tension reroutes through its neighbours. No single thread carries the load, so no single attack break brings it down. Engineers call it redundancy.

Now squint at a well-run South African property. Same trick.

One guard was never the plan

SA has quietly built one of the largest private security industries on the planet: Over 580,000 active officers, more than double the 150,000 police serving 62 million people. That's roughly one private officer for every 106 people, versus one cop for every 359.

When the state strand can't carry the load, the load reroutes: Armed response, alarm monitoring, vehicle tracking, neighbourhood patrols, the WhatsApp group that lights up before the siren does. Woven together, they become what no single one of them is.

The same logic runs down to a single site. A modern estate never leans on one thing; it stacks strands, each with a job:

None of it is there to look good on a spec sheet. They’re there to absorb a hit without failing.

The night one strand goes dark

Now let’s put the concept into practice: Signal jamming is one of the most common tools in SA crime: hijackings, follow-home robberies, cash-in-transit. And it targets a real weak point, because hijackings now make up around 56% of all car thefts in SA, where a jammer buys the criminal a crucial few minutes.

In one hit, a cheap jammer can: block the alarm panel from reaching the control room, kill the electric gate motor, silence the panic button and cut the GPS tracker mid-getaway. Four "layers" all failing at the same time.

And if every one of those runs over the same wireless signal, they were never separate strands — they were one strand wearing four hats.

That's the whole idea behind the dual-path monitoring in the SAIDSA bylaws: split the critical jobs across different transmission paths so no single jammer can take them all.

The Olarm APP-connected MAX pushes this further. It sends every message over 4G and WiFi at the same time, across dual SIMs, then deduplicates them in the cloud, so the signal is already travelling several roads at once and knocking out one changes nothing.

The new Olarm ONE system hardens the strands themselves: Its Olarm HALO wireless resists jamming far better than traditional wireless, and the Olarm HUB at its centre adds a wired Ethernet option too. Cut a strand, the tension finds a new path.

That's the spider web, in a DIN rail.

Rectron, one of SA's largest tech distributors, confirmed a cyberattack on 22 July that shut down its systems, closed its offices, and left resellers unable to place or dispatch orders. It has notified the Information Regulator that customer data may be affected.

Signal: Your supplier's breach becomes your problem. Ask who holds your data upstream, not just how you lock your own doors.

Investec became the first big SA-listed company to foot its executives' personal security bill, and the figure is public: about R3 million a year for two people, R12.6 million over four years. Vodacom's disclosure implies even more for its CEO.

Signal: Close protection is quietly becoming a board-level line item. If you offer it, this is the market telling you exactly what it'll pay.

Humanoid robots are being tipped for explosive growth, with analysts projecting a market worth tens of billions within a decade as manufacturing scales and unit costs drop.

Signal: Patrol and guarding roles sit squarely in the blast radius. Worth tracking who ships a security-grade unit first.

Microsoft's July update fixed 622 vulnerabilities, including three zero-days already being exploited. That’s one of the largest single batches on record.

Signal: Every Windows box in your control room is on that list. "We patched" should have a date next to it.

A new empirical study on "fraud-cyber convergence" found teams that treat physical fraud and cyberattacks as one problem catch more and lose less than those running them in silos.

Signal: The wall between "security" and "IT security" is dissolving. The operators who bridge it win the contract.

When an Olarm communicator talks to monitoring software, it sends Contact ID (CID) signals, and if those aren't set up right, the control room sees the wrong event or misses it entirely. Olarm has rolled out a set of Olarm-specific CID signals, and getting your templates updated is a small job that prevents big headaches:

Updating your signals template takes minutes, but only if your team knows which signals changed and why.

Olarm Academy's free New Olarm Signals course walks your team through the full list.

Anthropic went digging inside its own Claude models and found something nobody built on purpose: a hidden internal "workspace" where the AI quietly thinks before it speaks. Using a new tool called a Jacobian lens, researchers could read that silent layer, and in one test scenario watched the model privately reason through words like "leverage" and "blackmail" that never showed up in its actual reply.

Here’s the weird bit: Switch the workspace off and its fluent chat survives, but real multi-step reasoning collapses.

Signal: We're wiring AI into cameras, alarms and control rooms fast. This is a reminder that the box can be "thinking" things it doesn't say out loud, so demand tools that show you what your AI is actually doing, not just its polished answer.
