The insurance sector faces mounting pressure from both commercial growth and a persistent, evolving cyber threat landscape. This blog examines why insurers remain key targets, where their security gaps lie, and how cyber threat intelligence helps close the gap between ambition and resilience.

The NHS, MoD, and Metropolitan Police have each built deep operational dependency on Palantir through contracts largely awarded without competitive tender. Parliament has called it "an unacceptable point of weakness," Sadiq Khan blocked a £50 million Met Police deal, and the pattern keeps repeating: enter below scrutiny thresholds, build dependency, make exit expensive.

Rail networks sit at the intersection of critical national infrastructure and daily public life, making them a persistent target for protest, industrial action, infrastructure crime and, in parts of Europe, suspected sabotage tied to geopolitical tensions. This analysis from CYJAX sets out the physical threat picture in the UK alongside that of the wider continent.

The final part of CYJAX's rail cybersecurity series sets out a practical, five-step roadmap for building a rail-specific threat intelligence capability, covering regulation, coverage, and where to start regardless of maturity.

An OpenAI agent broke out of its test sandbox and autonomously breached Hugging Face with no human direction, an incident both companies called unprecedented. CYJAX examines why this doesn't fit existing threat actor categories, maps it to the standard attack lifecycle, and outlines three additions CTI teams should make to their collection plans and PIRs to track autonomous offensive tooling before it hits their own network. On 16th July 2026, Hugging Face disclosed that it had been breached.

Part two of CYJAX's rail cybersecurity series looks at why generic threat intelligence falls short in a rail environment, from safety-constrained response options to legacy protocols and a fragmented supply chain, and what rail-specific intelligence needs to deliver instead.

UK railway cybersecurity spending is accelerating as ransomware, insider incidents, and IT/OT convergence expose the sector's growing attack surface. Part one of CYJAX's rail security series looks at the numbers behind the trend and what they mean for UK operators.

From a fast-scaling ransomware operator to a Russian state-sponsored espionage group now experimenting with LLM-powered malware, and a data extortion collective that has weathered arrests without slowing down, these three threat actors span the full spectrum of financially and geopolitically motivated cybercrime. CYJAX breaks down what each group does, why they matter, and what security teams should know.

The CLOUD Act compels US-incorporated vendors to hand over data on request, regardless of where it's hosted. Here's why vendor jurisdiction matters for CTI.

The CSRB has cleared the House of Commons and Royal Assent is expected before the end of 2026. CYJAX breaks down scope, reporting timelines, penalties, and how threat intelligence underpins compliance.
