Most security programmes are built to watch the inside of the network, but the threats that do the most damage often start outside it: leaked credentials, impersonated domains, dark web chatter, and vulnerabilities under active discussion. This post looks at why the visibility gap exists, what the data says about it, and what closing it involves.

CYJAX intelligence is now built directly into Google SecOps SIEM and Microsoft Sentinel, giving analysts structured, normalised threat data inside the platforms they already use. Four feeds are live in Google SecOps and eight endpoints are available in Microsoft Sentinel's Content Hub.

Fraud against rail operators extends well beyond fare dodging. CYJAX breaks down how compensation scheme abuse, insider fraud and Telegram marketplaces for discounted tickets are combining to create a persistent revenue threat across the UK rail sector.

Domain Monitor's detection engine has been rebuilt to catch impersonation domains that keyword matching was never built to find. This release covers the new evidence-based matching engine, per-keyword Low, Medium and High thresholds, and what's coming next as the improvements roll out in stages.

From a ransomware-as-a-service group that can move from initial access to full encryption in under four hours, to a China-linked affiliate that has quietly pivoted to its own encryptor, these two threat actors show how mature the ransomware ecosystem has become. CYJAX breaks down what each group does, why they matter, and what security teams should know.

UK fintech is one of the country's fastest-growing sectors, but its reliance on APIs, partnerships, and real-time data makes it a prime target for cybercriminals. This blog explores why fintechs are so exposed, what the latest UK data reveals about breach costs and supply chain risk, and how cyber threat intelligence helps firms grow securely.
