Recommendations from the field
Here you will find practical guidance on protecting your business or household: e-mail phishing, SMS and WhatsApp scams (smishing), voice scams including fake relatives or IT support (vishing), fake “bank” messages, smartphone and home-router IoT hygiene, domain and mail setup (SPF, DKIM, DMARC), backups, strong sign-in, guest Wi‑Fi, system updates, CCTV and analytics, integrated building security, and ransomware recovery. We keep the language plain but include technical detail and real-world examples where they help.
