- Did US Tiger Securities Inc. offer free credit monitoring?
- Check your letter from US Tiger Securities Inc.. If free credit or identity monitoring is offered, the enrollment code and deadline are printed in the notice itself. Signing up doesn't waive any legal rights you may have.
- Can I sue US Tiger Securities Inc. over the data breach?
- It depends on what was exposed, the law in Washington and your own state, and whether you've been harmed. Most people take part through a class action rather than suing alone. Keep your notification letter — it's the proof that connects you to the breach.
- Do I need a US Tiger Securities Inc. data breach lawyer or attorney?
