Businesses lose more than $8B every year to IRSF attacks.

IRSF is the most menacing type of communication fraud. Fraudsters unethically obtain a range of premium rate numbers and target companies that generate a high volume of calls and messages. Fraudsters deploy sophisticated attacks to inflate traffic across their number range while siphoning money from every interaction. An IRSF attack happens in minutes and costs businesses $50k per attack, on average.

IRSF methods:

  • Multi-factor authentication (MFA) onboarding
  • Callback spam
  • SMS/Voice spam
  • Bots/Scripted attacks
