Computer Forensics Investigations

Network Security Breach & Cyber Threat

Computer ForensicsWith any active cyber threat, it is critical to understand the source and full extent of the network security breach in order to effectively respond and eradicate its presence in your environment. Our Computer Forensics and Network Security Specialists move quickly to capture and analyze data stored in your hard drives, CDs, DVDs, thumb drives and other media formats using industry standard incident response procedures.

Following evidentiary procedures to ensure integrity and admissibility, we will thoroughly investigate the incident while keeping you informed of all results. Computer Forensics and Network Security investigations can be performed during Incident Response Handling or independently, depending on your needs.

Understand the extent of the security breach and the compromise

Determining the source and full extent of a breach is vital to containing the incident and addressing the root cause. You need to know how far a hacker has penetrated your organization and systems, and what has been exfiltrated from your environment. In many cases, this can be accomplished only through in-depth Computer Forensics and Network Security Investigation.

The Allegiant Computer Forensics service gets to the bottom of how your systems were penetrated and what has been compromised. If you suspect systems and sensitive data have been compromised but do not have sufficient evidence to declare an incident, proper Computer Forensics Investigation can help you confirm a breach has occurred.

Ensure the integrity of the Chain of Custody

In the midst of an incident, following evidentiary procedures often is overlooked as your team focuses on containing the problem. This can impair your organization’s ability to provide reliable and useful evidence of the breach to proper authorities.

Our Computer Forensics experts perform a proper forensic investigation of your data storage devices, adhering to standards of evidence and legally admissible proof for criminal proceedings. We provide appropriate Chain of Custody documentation for systems, images or data acquired during the investigation. In addition, our investigators prepare reports or forensic evidence for appropriate law enforcement or investigating government agency upon request.

If your organization has become a victim of a security breach, or suspects a breach has occurred, contact Allegiant immediately at (469) 892-8256.
