are you, really?

8 questions. 2 minutes. See where your real gaps are — then fix them today, for free.

✓
I use a unique password for every account
⚠ One breach exposes everything if you reuse passwords. Use free Bitwarden password manager.
✓
Two-factor authentication (2FA) is enabled on my email
⚠ Your email is the master key to every other account. Enable 2FA today.
✓
2FA is enabled on my social media accounts
⚠ Takes 2 minutes per platform. Stops 90% of takeover attacks.
✓
My devices have the latest software updates installed
⚠ Updates patch security holes attackers actively exploit.
✓
I have a recent backup of important files (last 7 days)
⚠ If ransomware hits, a backup is your only escape.
✓
My work passwords are different from personal account passwords
⚠ Reusing passwords means one breach exposes both environments.
✓
I can recognize a suspicious link or phishing email
⚠ 91% of all cyberattacks start with phishing.
✓
My Wi-Fi router has a custom password (not the default one)
⚠ Default router passwords are publicly listed online.

Understand what
happened to you.

The three attacks that hit small organizations most.

Threat 01

Ransomware

Your files are locked by criminals who demand money to unlock them. Hospitals, schools and NGOs are the most targeted globally — ransomware attacks on healthcare surged 36% in 2025.

Right now:

Disconnect from internet immediately. Do not restart. Do not pay. Use First Aid above.

Threat 02

Phishing

A fake email or message tricks someone into clicking a bad link. In 2026, attackers use AI to write convincing messages in local languages — Arabic, Hindi, Swahili, Tagalog.

Prevention:

Never click links in emails. Type the website address directly into your browser.

Threat 03

Data Breach

Someone stole your patient records, student data, or donor information. NGOs are 3× more likely to suffer breaches than private companies — and rarely find out until it's too late.

Right now:

Change all passwords from a clean device. Notify affected people within 72 hours.
