CyberHerd Guardian by Cyberherd Ltd

Spot the risk. Understand the choice. Practise the skill.

CyberHerd Guardian is a free, privacy-conscious browser companion designed to help children, young people and families recognise online risks, make safer decisions and develop practical cybersecurity skills.

Guardian works directly in your browser, examining supported webpage content locally and providing friendly, age-appropriate guidance when it recognises potential warning signs.


🛡 Online safety guidance

Guardian looks for selected warning signs, including suspicious messages, phishing attempts, requests for personal information, harmful language, bullying, threats and potentially inappropriate content.

🐮 Friendly CyberHerd characters

Helpful characters explain potential risks using approachable language and practical advice, rather than technical jargon.

👨👩👧 Age-appropriate support

Choose from three guidance modes: ages 7–9, 10–12 and 13+. Guardian adjusts its warnings and explanations to suit the selected age group.

🔐 Password tools

Generate stronger passwords, explore memorable story-based passwords and receive password-strength guidance.

🔎 Safer browsing tools

Includes SafeSearch assistance, potentially risky download warnings, sensitive-information reminders and cookie-consent assistance.

♿ Accessibility options

Personalise text size, fonts, line spacing, colours and contrast to create a more comfortable browsing experience.

🎮 Learn with CyberHerd

Guardian connects relevant online safety topics to interactive educational games at cyberherd.online, helping learners practise what they have discovered.


Guardian's page-risk analysis runs locally in your browser. CyberHerd does not receive your browsing history, scanned webpage text or detected safety warnings.

No CyberHerd account is required. Supported preferences may be stored using browser storage, while optional learning links open the CyberHerd website separately.


CyberHerd Guardian is an educational safety aid, not a substitute for parental supervision, professional safeguarding advice or browser security protections.

Its detection uses rule-based checks, which can sometimes miss harmful content or identify harmless content incorrectly. Images, videos and some embedded content are not analysed.

Built by CyberHerd to make online safety and cybersecurity education more accessible.
