Why: Expertise

Defining Best Practices in Digital Forensics & IR

From a foundation in incident response and digital forensics, Mainstream’s experts deliver the full spectrum of information security services—from penetration testing, network assessment and social engineering to risk management, governance and compliance. We have deep experience with digital evidence recovery and frequently serve as expert witnesses.

Through successful investigation, the Mainstream team has helped Fortune 500 businesses and public sector organizations recover from advanced attacks and sophisticated breaches, including:

  • State-sponsored attacks
  • Financial crime
  • Insider threats

Our team specializes in investigating large-scale intrusions performed by the most advanced threat groups. We gather intelligence to identify the actions of the attacker, scope the compromise and data loss, and define the steps required to remove the attacker and re-secure the network.

Mainstream has developed and maintains profiles of key attack groups, including their tools, practices and objectives. By utilizing proprietary network traffic analysis and host inspection tools, Mainstream consultants automate typical investigative tasks and apply intelligence and lessons learned from previous investigations. This allows Mainstream consultants to investigate large-scale network intrusions more quickly and completely than is possible when traditional investigative techniques are used.

We are a top training partner with the US Secret Service and law enforcement officers around the country on forensic best practices. Our approach is built on: CERT, SANS and NCFI methodologies, developed by Department of Defense.
