Identity theft happens when someone steals your personal information — Social Security number, card details, account logins — and uses it to commit fraud in your name. The good news: most of it is preventable with a handful of habits. Strong unique logins, a credit freeze, transaction alerts, and a healthy suspicion of unexpected messages stop the overwhelming majority of attempts. Here’s a practical, prioritised guide to locking down your identity — and exactly what to do if you’re targeted anyway.

Zero-knowledge encryption is a security model in which the provider has zero knowledge of your data: everything is encrypted and decrypted on your own device, and only you hold the key. Even the company storing your information can’t read it — and neither can a hacker who breaches their servers or an authority that demands access. It’s the gold standard behind trustworthy password managers and secure cloud storage. Here’s how it works, and why it should shape which services you trust.

A web application firewall (WAF) is a security layer that sits in front of a website or web app, inspecting incoming traffic and blocking malicious requests before they reach your server. Unlike a traditional firewall that guards your network’s perimeter, a WAF understands web traffic specifically — so it can stop attacks like SQL injection, cross-site scripting, and malicious bots that target applications directly. Here’s how a WAF works, the types available, and whether you need one.

AI workflow automation uses artificial intelligence to carry out multi-step business processes — reading information, making decisions, and taking actions — with little or no human input. It goes beyond rule-based automation by handling the messy, judgement-based steps that used to need a person: understanding an email, classifying a document, drafting a reply. Here’s what it really means, ten concrete examples of it in action, and how to start without writing code.
