How Alex works

“I start by asking whether there is a real security problem or just a scary-looking message. I want to know what happened, what evidence supports it, what information may be exposed, and what the safest practical response is.”

Alex writes for DepartmentOfInternetSecurity.net, helping people understand online threats without turning cybersecurity into jargon or panic.
