Posted on September 30, 2020 by in Data Breach & Technology, Identity & Privacy, Personal

Phishing attacks and unsecured databases continue to pose a serious risk to Personally Identifiable Information (PII) of millions of individuals. In September, we saw an increased risk to children’s sensitive information with gaming companies and children’s hospitals being targeted.

IdentityForce has recently received the Parent Tested Parent Approved Seal of Approval for the 7th year in a row. Our ChildWatch product is the first of its kind identity theft protection designed for children’s developing identities, delivers alerts and messages directly to parents and safeguards against child identity theft.

Here are the recent data breaches that made headlines in September 2020:
