The evidence
A warning is only useful when you know why.
GuardScope separates technical evidence from guesswork. Every assessment shows the signals that shaped it and the action worth taking next.
Link reputation
Phishing and malware intelligence across every detected destination.
Domain history
Age, registrar signals, lookalikes and suspicious infrastructure.
Message intent
Impersonation, urgency, credential theft and payment pressure.
A deliberate workflow
Inspect only when something feels wrong.
GuardScope does not sit noisily between you and every email. You choose the message. GuardScope returns the evidence.

Clear answers
Trust should begin with scrutiny.
Does GuardScope store my email content?
No. The selected message is processed for the scan you request and its body is not stored in GuardScope databases.
What happens after five trial scans?
Scanning pauses until the account has an active subscription. Your account and local results remain available.
Why is an account required?
Your account keeps trial usage and subscription access synchronized between the website and Chrome extension.
Is a low score a guarantee of safety?
No security product can provide that guarantee. GuardScope gives you evidence and a practical recommendation for a better-informed decision.
