MV3-native
Built for Chrome Manifest V3 from day one — no deprecation warnings, no broken background pages.
Why switch
BankGuard vs Chrome Safety Check
Chrome's built-in Safety Check reacts after Google flags a malicious extension. BankGuard runs scoped detection on 50+ banking sites in real time so a rogue extension cannot read your transfer page before Google's catch-up.
| Feature | BankGuard | Chrome Safety Check |
|---|---|---|
| Monthly price | $2.99/mo | Free (with the trade-offs above) |
| Account required | No — install and use immediately | Often yes (varies by competitor) |
| Data leaves the browser | No — on-device by default | See competitor privacy policy |
| Ownership transfer risk | Aegis never sells extensions | Varies — see ExtensionWatch in this catalog |
| Bundled with Aegis Pro Pack | Yes — $9.99/mo unlocks every extension | No bundle |

Common questions
- Which banks does BankGuard cover?
- Chase, Bank of America, Wells Fargo, PayPal, Venmo, Coinbase, Robinhood, Fidelity, Vanguard, plus 40+ more US and EU institutions. The full list ships in the extension's domain registry, no remote update required to add coverage.
- Does Safe Mode lock my password manager out?
- No. Safe Mode disables only general-purpose extensions on the banking tab. Common password managers (1Password, Bitwarden, KeePass) are kept on a trust allowlist so login still works.
- Why a separate tool from Extension Guardian?
- Extension Guardian audits every installed extension. BankGuard is scoped to banking sites and acts in real time when one of those sites is open. Two different jobs — one is "review your installs," the other is "lock down right now."
- How does the Aegis Pro Pack unlock BankGuard?
- Sign in to aegisfirma.com from any installed Aegis extension popup. The cookie-auth flow detects your active Pro Pack and unlocks Pro features instantly — no license key to copy or paste.
- Where is my BankGuard data stored?
- BankGuard stores everything in chrome.storage on your device. Your subscription record lives in our payment provider's account; we do not aggregate browsing or activity data.
- Can I cancel BankGuard Pro anytime?
- Yes — billing stops at the end of the current period. Pro features remain active until the period ends, then drop back to the free tier.
- Why should I trust an extension I just heard of?
- Aegis extensions never change ownership and never sell user data. We publish security audit results and ship MV3-native code so Chrome itself enforces the permissions we claim.
