The threat landscape is outgrowing the old model
28th October 2026Why True Transfer is arriving at precisely the right moment
The cyber world we built our defenses for no longer exists. Attackers have stopped battering the front doors of large enterprises and started walking in through their suppliers, and AI now lets them try hundreds of those side doors in the time it takes most businesses to complete a single vendor review. It has happened faster than any of us imagined, and the way we protect our businesses, and the way we insure them, has not kept pace.
But it is not too late. The losses this new reality makes inevitable - the ones that start with a vendor and land on an enterprise with no one able to pay for them - have not yet arrived at scale. That window is exactly what True Transfer has been built for. It gives enterprises and their vendors a way to move the financial impact of a vendor incident onto cover designed to carry it, so that unpaid vendor loss is something they are protected against rather than something they discover the hard way.
Here is why the timing matters, and why True Transfer is arriving at precisely the right moment.
Vendor risk used to be a side issue
For most of the last decade, third-party cyber risk was something enterprises managed through questionnaires, contract clauses and an annual review, and for the world as it was, that approach made sense. The attacks that mattered were aimed at large organizations with valuable data and deep pockets, and the smaller suppliers around them were rarely the way in. When a vendor did suffer an incident, the knock-on effect for its clients was usually contained, and the losses were small enough to be absorbed, negotiated or quietly written off.
Vendor exposure was real, but it was marginal. The way enterprises protected themselves, and the way cyber insurance was structured, reflected that. There was simply no pressing reason to build anything more, because the scale of the problem did not demand it.
Attackers no longer need to break down the front door
Attackers have worked out that the easiest way into a well-defended enterprise is through the suppliers, platforms and software it shares with everyone else. Enterprises have spent years hardening their own perimeters, but the smaller businesses they depend on have not had the resources -or funds - to keep up.
The Stripe merchant key leak in August 2026 shows how little effort this now takes. Stripe itself was never breached. Instead, attackers searched for API keys that merchants had accidentally left in public view, then used them to pull customer and payment data from 659 businesses across 42 countries, with claims of around 20,000 more keys in reserve. There was no sophisticated malware and no attack on the big platform, just a search across a supplier hundreds of businesses had in common. Your vendors do not need to be targeted to be compromised; they only need to share a weakness with everyone else.
Shared software works the same way. In October 2026, a critical flaw in Atlassian's Data Center products, including Jira and Confluence, drew exploitation attempts within two hours of its details going public, exposing credentials and keys for organizations in almost every sector. The window to patch is now measured in hours, not weeks.
What has changed is the cost of doing this at scale. AI is turning work that once took skill, time and patience into little more than a set of instructions.
When hitting hundreds of vendors at once takes hours instead of months, the volume and impact of these attacks will rise sharply, and the protections most businesses rely on today were never built for it.
Why this matters: one weak link, many clients
The reason this shift matters so much is the way modern supply chains are connected. An enterprise relies on its vendors, those vendors rely on their own suppliers, and those suppliers rely on shared platforms, cloud services and software. Third, fourth and nth party relationships mean that a single weak link can spread across a vendor's entire client base, and from there into its clients' client bases, often far beyond anything the original enterprise could see or assess.
For enterprises, this means carrying risk that sits largely outside their view and their control. When an incident starts with a vendor, the disruption, data loss and recovery costs still land on the enterprise, and getting that money back depends on whether the vendor can pay. For a large supplier that may be possible; for the smaller, less defended businesses, attackers are increasingly reaching, it often is not. The result is unpaid vendor loss: real financial damage that falls on the enterprise because there is no one positioned to absorb it.
Vendors face the other side of the same problem. A single incident can now affect many clients at once, creating financial exposure far larger than the vendor's own business was ever sized to carry. That puts client relationships, contracts, and in some cases the survival of the business on the line, all from a weakness that may have been shared with hundreds of other suppliers. This is the exposure True Transfer exists to take off the table, for both sides of the relationship.
Insurance built for a different world
Cyber insurance grew up in the world described at the start of this piece, where vendor exposure was marginal, and its structure still reflects that. An enterprise's own cyber policy is built mainly around incidents in its own systems. A vendor's cover is sized for the vendor's own business, not for losses spread across its whole client base. Neither was designed for a world in which one supplier's weakness can cause damage to many enterprises at once.
The space between those two policies is where unpaid vendor loss sits. It was a narrow gap when attacks on suppliers were rare and contained. With attackers deliberately reaching enterprises through their vendors, and AI making that cheaper and faster every month, the gap is now real and growing, and it is exactly the gap True Transfer has been built to close.
Just in time
None of this means the battle is lost. If the market had already outgrown the old model, we would have heard about unpaid vendor losses piling up across every sector. We are not there, yet.
What we can see instead is every condition for that future falling into place: attackers who have learned to reach enterprises through shared suppliers, AI that lets them do it at scale in hours, and an insurance structure that leaves the resulting losses with nowhere to go. We are at the tipping point, and that is exactly the moment to act.
That is why True Transfer is launching now, not in five years' time when the losses are already on the books. For enterprises, it means the financial impact of a vendor incident no longer depends on whether that vendor can afford to pay. For vendors, it means a clear, credible answer when clients ask what happens if something goes wrong, and the ability to stand behind those clients without staking their own business on it.
This is a genuine opportunity, and a rare one: the chance to get ahead of a risk before it becomes a crisis. Enterprises and vendors that move before the losses arrive at scale will not be reacting to the next shared-supplier attack; they will already have an answer to it. The obvious next question is why something this logical has not existed before, and the answer lies in a problem that had to be solved first: you cannot transfer a risk you cannot measure. That is the subject of our next piece.
