Cybersecurity basics that still stop most breaches

Most incidents are not “advanced persistent threats”. They are reused passwords, shared admin accounts, and unpatched dependencies — boring problems with expensive consequences.

People and process

Train teams to report suspicious messages without shame. Phishing tests are useful only if they build habits, not blame.

Third-party risk

Keep an inventory of vendors with access to your data. If you cannot name them, you cannot revoke them when someone leaves.

Custom software

For software you ship to clients, insist on dependency updates and penetration tests before major releases. Security is a release criterion, not a slide in a pitch deck.
