Every piece of email security advice eventually lands in the same place: you are the last line of defense. Recognize the red flags. Do not click suspicious links. Think before you act. It is good advice. It is also advice that assumes you will be alert, rested, and unhurried every single time — a standard no human can sustain at inbox scale.
The Problem with Solo Email Security
The security industry has spent decades training individuals to be their own defenders. And it works — until volume, urgency, and fatigue collide. The average adult receives more than 120 emails a day. Phishing attacks are engineered specifically to exploit the moments when your guard is down: unexpected messages that claim urgency, authority, or personal relevance. They are designed to short-circuit the skeptical pause that training tries to install.
For older adults, the pressure is compounded. Seniors are targeted at disproportionate rates not because they are less intelligent, but because attackers know that isolation, trust in authority figures, and less familiarity with how email infrastructure actually works are exploitable conditions. No amount of awareness training fully closes the gap between a determined attacker and a human operating alone.
The answer is not more training. It is structural. You need a system where a trusted second person is part of the decision — without that person having to monitor your inbox.
What if Your Trusted Contacts Were Part of Your Defense?
Glance's Circle of Trust is built on a simple premise: the people who know you best are better equipped to judge whether an unknown sender is legitimate than any algorithm acting alone. The Circle of Trust lets you designate between one and five people — family members, partners, trusted friends — as gatekeepers for your inbox.
Here is how it works: when an email arrives from a sender who is not already on your allowlist, that email does not go directly to your inbox. It goes to your gatekeepers for review. Your gatekeeper sees three things: the sender's name, the sender's email address, and the subject line. They also see Glance's threat score for that sender — a 0–100 number derived from six layers of analysis. They do not see the email body. Ever.
Zero-Knowledge by Design
Gatekeepers make decisions based on identity signals, not content. Your email body is never shown to anyone in your Circle of Trust. This is not a setting you toggle — it is enforced at the architecture level.
How Approval Works
When Glance holds an email for review, your designated gatekeeper receives a push notification. The notification shows the sender details and Glance's AI analysis summary — a plain-language explanation of why the sender was flagged, or why it looks clean despite being unknown. The gatekeeper has two options: Approve or Block.
An approval is permanent. The sender is added to your allowlist and all future emails from that address go straight through without review. A block is also permanent — the sender is added to your blocklist, and future emails from that address are rejected automatically. One decision resolves the relationship forever.
If the gatekeeper does not respond within your configured window, the email stays in the quarantine queue — it does not bounce or disappear. You can also configure a secondary gatekeeper so that important decisions are never blocked by one person being unavailable.
Unknown sender arrives
Glance intercepts the email before it reaches your inbox and runs six-layer threat analysis.
Gatekeeper notified
Your designated gatekeeper receives a push notification with sender details, subject line, and Glance's threat score and AI summary.
One tap decides
Gatekeeper taps Approve (sender goes to allowlist) or Block (sender goes to blocklist). Decision is permanent.
Inbox updated
Approved email is delivered. All future emails from that sender arrive directly, no review needed.
Real-World Scenarios
The Circle of Trust adapts to how families actually work, not an idealized security configuration.
Adult child protecting a parent
A 68-year-old receives a message from 'Medicare Benefits Dept.' — an address she has never seen. The email holds. Her daughter gets a notification: sender flagged 91/100, domain registered 4 days ago. One tap: blocked. Her mother never saw the scam.
Partners protecting each other
Two spouses add each other as gatekeepers. When one is traveling and receives a suspicious wire transfer request from an unknown finance address, their partner flags it from across the country in under two minutes.
Small business team
An operations manager adds two trusted colleagues as gatekeepers. Business email compromise attempts — fake invoices from lookalike domains — get caught at the gatekeeper review stage before any payment decision is made.
Caregiver managing a household
A professional caregiver is added as gatekeeper for an elderly client. Unknown senders are reviewed by someone who understands the client's situation, not a generic algorithm making binary decisions.
What Makes This Different from Normal Email Forwarding
The most common objection to the Circle of Trust model is a privacy concern: does adding a gatekeeper mean someone can read my emails? The answer is no — and this is the most important distinction between Glance's system and forwarding a copy to a family member.
Email forwarding gives the recipient full access to your message content. There is no way to limit what they see. Glance's gatekeeper model is architecturally different: email content is never transmitted to gatekeepers. The gatekeeper decision is made on sender identity and threat signals only. This preserves your privacy completely while still giving a trusted person meaningful input on whether an unknown sender should reach you.
- Known contacts — people already on your allowlist — always go through. Gatekeepers only review truly unknown senders.
- Gatekeeper access can be revoked at any time from your settings.
- You receive a digest of all gatekeeper decisions so you always have full visibility.
- Gatekeepers can protect multiple people — one trusted family member can be a gatekeeper for both parents.

Build Your Circle FreeFrequently Asked Questions
How long does gatekeeper approval take?
Most approvals happen within minutes. Gatekeepers receive a push notification the moment an unknown sender arrives. One tap approves or blocks. If a gatekeeper does not respond within a configurable window, the email is held in the quarantine queue — it does not bounce or disappear.
Can gatekeepers read my emails?
No. Gatekeepers see only the sender name, sender email address, subject line, and Glance's threat score. The email body is never shown to gatekeepers. This is not a policy restriction — it is enforced at the architecture level. Zero-knowledge means the gatekeeper decision is made on identity signals, not content.
What happens if my gatekeeper ignores a notification?
The email stays in your Glance quarantine queue. You can configure a fallback — either auto-approve after a set number of hours, or keep it held indefinitely until manual review. You also have the option to add a second gatekeeper so that important emails are not delayed by one person being unavailable.
Can I be my own gatekeeper?
Yes. If you prefer to handle approval decisions yourself, you can designate yourself as your own gatekeeper. You will receive the same threat-score notification for every unknown sender and make the call directly. This is useful for technically confident users who want full control without involving others.
