The best online safety for kids combines three things: open conversations, clear family rules and sensible technical controls. No filter or app replaces a child who knows what to do when something goes wrong, and who feels safe telling you about it. This guide covers the main risks, internet safety for children by age, practical online safety rules and how to start teaching digital safety.
The main online risks
- Inappropriate content: violent, sexual or frightening material, which can appear through search, videos or ads.
- Contact from strangers: including grooming, where an adult builds trust with a child for harmful purposes.
- Cyberbullying: harassment, exclusion or humiliation through messages, games or social media.
- Privacy and data: sharing personal details, location or photos that can be misused.
- Scams and phishing: fake prizes, links or in-game offers.
- Sextortion and image sharing: pressure to send images, followed by threats. This is a growing risk for teens in particular.
- Excessive use: compulsive design features that make it hard to stop.
- Misinformation and harmful communities: content promoting self-harm, extreme diets or hateful ideas.
Internet safety for children by age
Ages 2–5
- Use devices together, in shared spaces.
- Choose curated, ad-free apps and enable parental controls and child profiles.
- Teach one basic rule: ask a grown-up before tapping or clicking.
Ages 6–9
- Keep computers and tablets in common areas.
- Use filters and safe search, and approve games and apps in advance.
- Teach "stop, close, tell": if something upsetting appears, close it and tell you.
- Explain that people online may not be who they say.
Ages 10–13
- Agree on rules before social media or messaging accounts begin, and check the current age requirements for each platform and your country.
- Review privacy settings together.
- Talk about cyberbullying, sharing photos and what to do if a stranger contacts them.
Ages 14–17
- Discuss healthy relationships, consent, image sharing and sextortion.
- Talk about scams, misinformation and digital footprints.
- Respect growing independence while keeping communication open.
10 online safety rules for the family
- Keep personal information private: full name, address, school, phone number and passwords.
- Use strong, unique passwords and never share them with friends, only with parents.
- Only talk to people you know in real life, and be cautious about friend requests.
- Never agree to meet an online contact without a parent, and do not do it in secret.
- Think before you post. Once online, content can be copied and shared.
- Be kind online. Do not join in bullying, and report it.
- Do not click on unknown links or download files from strangers.
- Tell a trusted adult if anything feels weird, scary or wrong.
- Keep location sharing off unless a parent approves it.
- Balance screens with sleep, play and friends.
Teaching digital safety: how to talk about it
- Start early and keep talking. Short, frequent chats work better than one big lecture.
- Stay curious, not angry. Ask what games and apps they love and who they play with.
- Promise not to overreact. Children hide problems if they fear losing their device. Tell them: "You will never be in trouble for telling me."
- Use real examples. News stories and scenarios make it concrete.
- Teach critical thinking. Ask "Who made this? Why? Can I check it?"
- Make a plan together for what to do if someone sends a message that scares them: record the account details, block, report and tell a trusted adult. Save screenshots of abusive text only; do not copy, download or forward explicit images of a child.
Helpful tools
- Parental controls: built into iOS, Android, Windows, games consoles and many apps.
- Safe search and content filters in browsers and streaming services.
- Privacy settings: set accounts to private, restrict who can message and tag.
- Screen time tools to limit use and set downtime.
- Password managers for older kids.
Tools support rather than replace conversation. Teens can often find ways around them, so trust and communication are the strongest protection.
Signs your child may be struggling online
- Sudden secrecy, hiding screens or deleting messages
- Changes in mood, sleep, appetite or school performance
- Withdrawing from friends or activities they enjoyed
- Receiving gifts or money from unknown people
- Distress after using a device
What to do if something goes wrong
- Stay calm and thank your child for telling you.
- Keep usernames, links and dates, and screenshots of abusive text where safe. Do not copy, download or forward explicit images of a child; follow police or child-protection guidance.
- Block and report the account on the platform.
- Contact the school in cases of bullying involving classmates.
- Report serious crimes such as grooming or sextortion to the police, and in the US to the National Center for Missing & Exploited Children (NCMEC) CyberTipline. For image-based abuse, NCMEC’s Take It Down service can help limit sharing of qualifying images on participating platforms. Use only files already on the original device; do not download an image to submit it.
- Support their feelings and consider counselling.

The takeaway
Online safety for kids is a long conversation, not a one-time setup. Combine clear rules, smart settings and a home where your child knows they can always come to you.
