The Call Logs feature displays a complete history of all phone calls in a clear and easy-to-understand format.

Different icons are used to clearly identify call types:

  • Outgoing calls are shown with an arrow icon
  • Incoming calls are shown with a different arrow direction
  • Missed calls are shown with a separate icon

If a call is received from an unknown number, the app searches the number in its database, similar to how caller identification apps work. If the number is found, the name is fetched from the app’s and shown in the call log.

This feature helps users easily track their call history while also identifying unknown numbers with accurate details.

Summary

Unique Feature: Purpose-Based Calling (CDEF to CDEF Users)

When both the caller and receiver are using the CDEF app, the Quick Call button is replaced with a red Purpose icon.

After tapping it, the caller can:

Select the type of call from a dropdown:

  • Emergency Call
  • Promotional Call

  • What the Receiver Sees:

When the receiver gets the call, a priority pop-up alert appears on their screen showing:

  • Caller’s Name

  • Call Type (e.g., Emergency Call)
  • Other (e.g., “HELP ME”)
  • AI Threat Score (analyzed in real-time)

This ensures the receiver understands the urgency and context of the call before answering, enabling faster and more informed decisions.

Dark web scanning for leaked credentials is a proactive cybersecurity measure that continuously monitors hidden areas of the internet for compromised data related to individuals or organizations. Early detection of exposed credentials allows for immediate remediation, such as password resets, to prevent account takeovers, financial fraud, and data breaches.

Dark web scanning services use a combination of automated tools to find mentions of your data on illicit platforms. Users can enter their sensitive credentials like Mobile number, email ID, credit card, etc., Credit Card etc and check if they are leaked in any Darkweb websites.

Alerts are generated, providing details about the compromised data (e.g., username, password, source of the leak) and recommended next steps. This helps in taking preventive steps against possible cyber attacks based on your credentials by using this intelligence to prioritize risks and respond effectively before the credentials can be weaponized by threat actors for credential stuffing or other attacks.

The Filters feature helps users manage and control incoming calls by automatically blocking unwanted, spam, and potentially harmful calls. When a user taps on Filters, they will see four filtering options designed to improve call safety and reduce disturbances.

Available Filter Options

Users can enable or disable the following filters based on their preference:

1. Block Spam Calls

Automatically blocks calls identified as spam through our database and user reports. This prevents repeated nuisance calls from reaching the user.

2. Block Promotional Calls

Stops telemarketing and promotional calls from businesses and marketing agencies, helping users avoid unnecessary interruptions.

3. Block Cyber Fraud Calls

Blocks calls that are identified as suspicious or associated with cyber fraud activities such as phishing, financial scams, or identity theft attempts.

4. Block Contacts / Numbers

This option allows users to manually block any phone number or contact directly from the app. Once a number is blocked, calls from that particular contact will no longer reach the user.

Each option includes a toggle button on the right side, allowing users to turn the filter on or off anytime according to their preference.

How does it work?

Our system uses AI-powered threat scoring and advanced database analysis to evaluate phone numbers. Each number is assessed using multiple data points, including:

Previous spam reports from users

Call activity patterns

Number of hang-ups and suspicious behavior

Spam markings in the database

Historical call records associated with the number.

Based on this analysis, the system determines whether a number is genuine, promotional, spam, or potentially fraudulent, and filters the call accordingly.

By enabling these filters, users can significantly lower the risk of interacting with fraudulent callers while ensuring only relevant calls reach them.

Unlike traditional call-blocking solutions that rely only on static spam lists, our Filters feature uses AI-powered threat analysis and real-time database intelligence to identify risky numbers.
