How to Use CyberGuard AI

Set Protection Once. Let the App Handle the Noise.

CyberGuard AI is structured around simple actions: choose who can reach you, decide when blocking is active, and review what was stopped.

Choose Contacts

Allow saved contacts, block unknown callers, or create a specific allowed contact list for strict filtering.

Set Timings

Schedule call blocking for meetings, sleep, travel, study time, or any fixed period when calls should not disturb you.

Add Rules

Create prefix, suffix, range, number, country, and exception rules to match the way spam reaches your phone.

Review Activity

Blocking Modes

Block the Right Calls, at the Right Time

CyberGuard AI is built for real-life call control. You can block everyone, block only selected contacts or numbers, or block everyone except the contacts you trust.

For stricter protection, create an allowed contact list inside the app and reject every other caller. You can also apply time-based rules when you need calls blocked for a fixed period.

  • Block everyone with no exception during selected timings
  • Block everyone except your saved contacts
  • Block every contact except a specific allowed contact list
  • Block callers who are not in your contact list
  • View and manage all active rules from the app

Reject by prefix, suffix, range, or country code when a full series of numbers keeps calling.
