What is the purpose of digital forensics?

Extract data from electronic sources, convert it into actionable intelligence, and present findings in a clear, defensible format for legal or investigative review.

Digital forensic outputs are commonly used for:

• Civil and criminal litigation

• Employment and HR investigations

• Regulatory inquiries

• Data breach investigations

• Fraud and misconduct matters
