A plain-English breakdown of the technology behind each product — DNS filtering, MDM profiles, VPN proxies, AI scanning, and desktop sync. Understanding the mechanism tells you exactly what each tool can and can't do.
How it works The Gryphon replaces your existing router entirely. Every packet from every device on your network flows through Gryphon's hardware before reaching the internet. Gryphon maintains a continuously-updated blocklist of millions of domains across 50+ content categories. When a device requests a blocked domain, Gryphon's DNS resolver returns a null/blocked response — the request never leaves your home.
Key insight Because Gryphon IS the router, there's no way to "uninstall" it from within the network. A child would have to physically unplug the router and reconnect to a different internet source — which is very detectable. This makes it the most bypass-resistant home network solution available.
HomeBound is a VPN companion app (included with Premium) that creates an encrypted tunnel from iOS/Android devices back to your Gryphon router. When a device leaves home, all traffic still routes through Gryphon — same DNS filters, same rules. Uses the iOS VPN slot. Parent gets an alert if it's disabled.

How it works on iOS Qustodio installs two things: (1) an MDM configuration profile for device management — controls which apps run, enforces time limits, requires parent password to remove; and (2) a VPN profile that routes all web traffic through Qustodio's cloud servers for content filtering and monitoring. Both live in Settings → General → VPN & Device Management.
Plan difference Basic ($59.95/yr, 5 devices): web filtering, app blocking, screen time, location, social monitoring, AI alerts, gaming alerts. Complete ($109.95/yr, unlimited devices): adds YouTube monitoring, 30-day activity history, AI-powered message and search alerts, panic button, app download alerts. For multi-kid families or anyone who wants YouTube visibility — Complete is the right plan.
iOS limitation Qustodio cannot read iMessage, SMS, or in-app messages from Snapchat, TikTok, or Instagram on iOS. Apple does not allow any third-party access to these. The calls & messages monitoring feature on iOS requires running Qustodio Family Portal on a Mac or Windows computer — when the device syncs to the desktop app, call logs and some message metadata are captured. This is NOT real-time and NOT available without the desktop app running.

Three separate components Bark Premium combines three distinct technologies: (1) Cloud OAuth — you connect your child's Google account, iCloud email, YouTube, etc. Bark reads these via authorized API access, continuously, from anywhere. (2) Desktop sync — Bark Desktop on Mac/Windows syncs texts, photos, notes when the iPad is home on WiFi. (3) Bark Kids VPN app — a VPN-based web filter on the device that travels everywhere. These three components work independently of each other.
Why cloud monitoring is powerful Cloud-based Gmail/Drive monitoring works even when the device is off, broken, or at a friend's house — because the data lives on Google's servers, not the device. A child can't "block" this by turning off their phone. This is why Bark catches concerning emails and Drive documents that other products miss entirely.
Bark Jr vs Premium Bark Jr ($49/yr): screen time, web/app blocking, location tracking only. No AI content monitoring. Essentially a basic controls-only tool. Bark Premium ($99/yr): adds full AI monitoring of cloud accounts, Android social/text monitoring, desktop sync for iOS. Most families need Premium.
iOS fundamental limitation Snapchat, TikTok, Instagram, and Discord do not allow any third-party app to access their message content on iOS — period. This isn't a Bark limitation, it's Apple's privacy architecture. On Android, Bark has full access to these apps via device-level permissions. For an iPad household, Bark's value is cloud accounts (Gmail, YouTube, iCloud email) plus the web filter — not social media message monitoring.

|---|---|---|
| Gmail / Google Drive | ✓ Cloud OAuth — always-on | ✓ Cloud OAuth — always-on |
| iCloud email | ✓ Cloud OAuth — always-on | ✓ Cloud OAuth — always-on |

How the AI scanning works Canopy's VPN routes all device internet traffic through their servers. As images and video frames pass through, Canopy's computer vision model analyzes them in real-time for explicit content — nudity, sexual content, suggestive imagery. This happens before the content reaches the screen. If an explicit image is detected, it's replaced with a block screen and the parent is alerted.
Sexting prevention Canopy can detect explicit images being sent or received through any channel that passes through its VPN — browsers, most apps. The caveat: end-to-end encrypted apps (iMessage, Snapchat, Signal) encrypt their traffic before it hits the VPN tunnel. Canopy cannot scan inside that encrypted payload. So sexting detection works on browser-based sharing, web apps, and some non-E2E channels — but NOT iMessage or Snapchat on iOS.
Family plan Individual plan = $7.99/mo (3 devices, billed annually). Family plan = $9.99/mo (10 devices, billed annually). For families with multiple children, the Family plan is necessary and still less than Qustodio Complete or Aura.
Data usage warning Because ALL device traffic routes through Canopy's servers — including video streaming — it can consume 10–13 GB of cellular data per month on an active device. For families on limited data plans, this is a real cost to factor in.

Three separate systems in one subscription Aura bundles three independent technology layers: (1) Parental controls — MDM-based device profile on iOS/Android for content filtering, screen time, app blocking; (2) Identity protection — API connections to the three major credit bureaus plus dark web scanning for SSNs, passwords, financial accounts; (3) Safe Gaming — a Windows PC desktop agent that hooks into game audio/video output to monitor voice and text chat.
Parental controls on iOS Uses an MDM profile (similar to Qustodio) for device management: content filtering via SafeSearch, app blocking, screen time schedules, internet pause. Activity reports show browser history and app usage. Requires iOS 16+. No location tracking — Aura's parental controls do not include GPS/location features.
Safe Gaming is unique No other product in this comparison monitors gaming voice chat. The Windows desktop agent runs alongside games and uses AI to analyze conversations in 200+ PC games — flagging predatory language, threats, and grooming attempts. Reports are weekly, not real-time. Windows only — does not work on consoles, iPad, or Mac games.
Plans Kids Plan ($10/mo annually, $120/yr): parental controls + safe gaming + wellbeing tools. Family Plan ($32/mo annually, $384/yr intro, renews ~$35/mo): adds identity theft protection for the whole family — credit monitoring, $5M insurance, antivirus, VPN, password manager. Aura also owns Circle Home Plus, whose network-filtering tech is integrated into the Family Plan.
