Cyberbullying, online predators, phishing scams, and inappropriate content are real risks for kids on any device. You don’t need to be a tech expert to stop most of them. The right combination of built-in device controls, router-level filtering, and honest conversations covers the majority of threats your child will encounter.
What Are the Biggest Online Threats for Kids in 2025?
Most parents focus on screen time, but the real risks go deeper. Here are the threats we hear about most from Boca Raton families who come in after something goes wrong on a child’s device.
- Cyberbullying — Happens on Instagram, Snapchat, Discord, and group chats. Often invisible to parents until the damage is done.
- Online predators — Adults posing as peers on gaming platforms (Roblox, Fortnite) and social apps. They build trust slowly over weeks.
- Phishing scams — Fake prize links, “free Robux” offers, and spoofed login pages that steal account credentials or payment info.
- Inappropriate content — Explicit material, graphic violence, and extremist content that bypasses basic filters on unmanaged devices.
- Privacy oversharing — Kids posting their school name, neighborhood, or daily schedule without realizing the risk.
- Malware and spyware — Downloaded through game mods, cracked apps, or suspicious links. Can compromise your entire home network.
How to Set Up Parental Controls on Every Device
Every major platform has built-in parental controls — most parents just haven’t turned them on. Here’s exactly where to find them and what to enable first.
iPhone and iPad (iOS 17+)
Go to Settings → Screen Time → Content & Privacy Restrictions. Enable it and set a passcode your child doesn’t know. From here you can block explicit websites, restrict App Store downloads by age rating, and prevent changes to privacy settings.
The Downtime feature is the most underused tool here. Set it to block all non-essential apps from 9 PM to 7 AM. Your child can still call you, but social media and games go dark. Takes about 3 minutes to configure.
Android (Google Family Link)
Install Google Family Link on your phone and your child’s Android device. You approve every app download, set daily screen time limits, and can lock the device remotely from anywhere.
Family Link also filters Google Search and YouTube by default on supervised accounts. You can block specific websites in Chrome and get a weekly activity report showing which apps your child used and for how long.
Windows PC (Microsoft Family Safety)
Add your child as a family member at Microsoft Family Safety. Once linked, you can set content filters in Edge, cap daily screen time, and block specific apps or games by age rating.
The spending limit feature is worth enabling if your child has access to any Microsoft Store purchases. Set it to $0 and require your approval for anything.
Mac (Screen Time via macOS)
Go to System Settings → Screen Time and enable it for your child’s account. The Mac version mirrors the iPhone controls — app limits, content restrictions, and communication limits all work the same way. Enable Family Sharing in iCloud to manage it from your own iPhone.
Router-Level Controls: Network-Wide Protection
Device controls only work on the device. Router-level filtering covers every device on your home network — including smart TVs, gaming consoles, and any device your child connects to your Wi-Fi.
Built-In Router Controls
Log into your router’s admin panel (usually at 192.168.1.1 or 192.168.0.1 in your browser). Most modern routers from Xfinity, AT&T, and Comcast have a parental controls section built in. You can block categories of websites, set internet curfews by device, and pause Wi-Fi for specific devices on demand.
Look for your child’s device in the connected devices list, then assign it to a profile with restrictions. Xfinity’s xFi app makes this especially easy — you can pause your child’s internet from your phone in seconds.
DNS-Based Filtering (Free and Effective)
Change your router’s DNS server to CleanBrowsing Family Filter (185.228.168.168) or OpenDNS Family Shield (208.67.222.123). This blocks adult content and known malicious sites at the network level — no app required, works on every connected device automatically.
Log into your router
Type 192.168.1.1 into your browser. Use the admin credentials on the back of your router if you haven’t changed them.
Find DNS settings
Look under WAN settings, Internet settings, or Advanced. The exact location varies by router brand.
Enter the new DNS addresses
Primary: 208.67.222.123 (OpenDNS Family Shield). Secondary: 208.67.220.123. Save and reboot the router.
Test it
Try visiting a known adult site from any device on your network. It should be blocked immediately.
Third-Party Parental Control Apps Worth Using
Built-in controls are a good start. These apps go further — especially for monitoring social media activity and location.
| App | Best For | Cost | Works On |
|---|---|---|---|
| Bark | Social media monitoring, alerts for bullying/self-harm language | Starting at $14/mo | iOS, Android, Chromebook |
| Circle | Router + device control in one app | Starting at $10/mo | All home devices |
| Qustodio | Detailed activity reports, app blocking | Starting at $55/yr | iOS, Android, Windows, Mac |
| Net Nanny | Real-time content filtering, profanity masking | Starting at $40/yr | iOS, Android, Windows, Mac |
Bark is worth highlighting separately. Instead of blocking everything, it monitors your child’s messages and alerts you only when it detects warning signs — bullying language, mentions of self-harm, or contact from strangers. It’s less invasive than full monitoring and catches real problems without reading every message yourself.
What to Actually Say to Your Kids
Controls and filters work better when your child understands why they exist. A kid who knows what a phishing link looks like is safer than one who just has a filter they’re trying to bypass.
- Explain that you’re not spying — you’re watching for dangers the same way you’d watch traffic before they cross the street.
- Show them a real phishing example. The “free Robux” or “you won an iPhone” scams are easy to spot once you’ve seen one.
- Teach them the rule: never share your real name, school, address, or phone number with anyone you haven’t met in person.
- Make it clear they won’t get in trouble for telling you if something feels wrong online. Fear of punishment is why kids hide problems.
- Review their friend lists together occasionally — not as surveillance, but as a conversation about who they’re talking to.
Red Flags That Something Is Wrong on Your Child’s Device
Sometimes the first sign of a problem isn’t what your child says — it’s what their device shows. Here’s what to look for.
- New apps you didn’t approve, especially ones with generic names or no icon
- The device is unusually hot, slow, or draining battery faster than normal (possible malware)
- Your child hides the screen or closes apps when you walk by
- Unexplained charges on your credit card or gift card requests
- Mood changes after device use — withdrawal, anxiety, or anger
- Accounts you don’t recognize in the browser history or app list
We’ve seen devices come in from Boca Raton families where a child had downloaded a game mod that installed a keylogger — software that records every password typed on the device. A full malware scan caught it before any accounts were compromised. That’s a at either of our locations.
No Protection in Place
- Unrestricted access to any website or app
- No visibility into who your child talks to
- Malware can spread to other home devices
- No record of activity if something goes wrong
Layered Protection (Device + Router + Conversation)
- Content filtered at device and network level
- App downloads require your approval
- Alerts if warning language appears in messages
- Child understands risks and knows to report problems
The families who come in after a problem almost always say the same thing: “I didn’t know that app was even on there.”

Frequently Asked Questions
What age should I start using parental controls?
Start when you hand them their first device — even if that’s age 6 or 7. The controls are easier to establish early than to add later when a child is used to unrestricted access. For younger kids, focus on content filtering and screen time limits. Add social media monitoring around age 10–11 when peer platforms become relevant.
Can my child bypass parental controls?
Yes, if you don’t set a Screen Time passcode or if they use a VPN app. The most common workaround is a VPN — it tunnels around DNS filters and some content blockers. Block VPN apps specifically in your device controls, and consider a router-level solution like Circle that can detect and block VPN traffic at the network level.
How do I know if my child’s phone has malware?
Watch for unusual battery drain, the phone running hot when idle, unfamiliar apps, or unexpected data usage spikes. These are the most common signs. A at Gadget Medics takes about 15 minutes and will tell you definitively what’s on the device. We serve Boca Raton families at both our Mission Bay Plaza and Clint Moore Road locations.
Are free parental control apps good enough?
The built-in tools — Apple Screen Time, Google Family Link, Microsoft Family Safety — are genuinely solid for content filtering and screen time. They’re free and don’t require a subscription. Where paid apps like Bark or Qustodio add value is in social media monitoring and detailed activity reports, which the built-in tools don’t cover well.
What should I do if my child was contacted by a stranger online?
Screenshot everything before deleting it. Report the account directly on the platform — every major app has a reporting tool. If the contact was sexual in nature or involved threats, report it to the NCMEC CyberTipline and contact local Boca Raton police. Don’t confront the stranger directly or let your child respond further.
Does Gadget Medics help with parental control setup?
Yes. We can set up Screen Time on iPhones and iPads, configure Google Family Link on Android devices, and walk you through router-level DNS filtering — all at our Boca Raton locations. If your child’s device has existing malware or suspicious apps, we’ll run a full diagnostic first. Most setups take under an hour.
The goal isn’t to lock down every device until your child turns 18. It’s to build layers of protection that match their age, and to keep the conversation open so they come to you when something feels off. Start with the built-in controls on whatever device they use most, add router-level DNS filtering, and check in regularly. For anything more complex — malware removal, device setup, or a second opinion on what’s actually on their phone — Gadget Medics is at 20437 State Road 7 (Mission Bay Plaza) and 1906 Clint Moore Rd in Boca Raton. Walk-ins welcome.
