Advanced Forensic Investigative Solutions
Turning Investigative Insight into Proactive Cyber Defense

Eric Mazur, Founder and President, Advanced Forensic Investigative SolutionsEric Mazur, Founder and President
Most organizations today discover insider-driven security incidents only after the damage is done. While they invest heavily in defending against external threats, 83 percent face insider threat attacks from departing employees or unauthorized actors who already have access to critical systems and information. Intellectual property may leave with departing employees and remain undiscovered until it appears online months later, while malicious insiders and compromised accounts may continue operating undetected within trusted environments. Organizations often discover these incidents months after the warning signs first appeared, by which time response costs have already escalated dramatically.

After more than 35 years conducting digital investigations across law enforcement and the private sector, Eric Mazur, founder and president of Advanced Forensic Investigative Solutions (AFIS), repeatedly saw this pattern. As a detective with the Metropolitan Police Department's Financial Investigations Unit in Washington, D.C., he conducted hundreds of investigations involving financial crimes and digital evidence. He later instructed federal, state, and local law enforcement officers through the Department of Defense Cyber Crime Center and developed deep expertise in investigating fraud, unauthorized access, trade secret theft, data manipulation and data destruction.

Those experiences led him to establish AFIS, helping organizations identify risks early and respond with defensible, cost-effective solutions.

“We're not in the business of speculation. We're in the business of finding facts, preserving evidence, and helping clients understand exactly what happened,” says Mazur.

Rather than waiting for incidents to surface, AFIS helps organizations identify risks before they escalate.

The firm's Departure Assurance Program (DAP) emerged from a recurring investigative problem. In many cases, organizations discovered after an employee's departure that confidential information, intellectual property, financial records, or other sensitive data had been accessed or removed. DAP categorizes departing employees by risk and business exposure, enabling proportionate, cost-effective forensic reviews before concerns evolve into larger disputes. The goal is straightforward: provide assurance when everything checks out and identify situations that warrant closer examination.

We're not in the business of speculation. We're in the business of finding facts, preserving evidence, and helping clients understand exactly what happened.

AFIS applies the same philosophy through RogueHunter. While organizations routinely invest in penetration testing to strengthen perimeter defenses and rely on incident response after a compromise, RogueHunter addresses the critical space in between. Operating from an “assume breach” mindset, it searches for unauthorized access, long-term persistence, reconnaissance activity, privilege escalation, and other evidence of active compromise before threat actors weaponize stolen data for ransomware, fraud, or extortion. It complements traditional security assessments by looking for evidence of compromise rather than simply evaluating defensive controls.

Both offerings reflect AFIS's evolution from investigating damage after the fact to helping organizations act on warning signs before crises develop.

As digital evidence spreads across cloud platforms, mobile devices, email systems, endpoints, and collaborative technologies, investigations have become more complex. AFIS supports clients through legally defensible data collection and preservation, forensic analysis, eDiscovery consulting, and expert witness services designed to withstand legal, regulatory, and courtroom scrutiny.

That proactive approach extends beyond internal networks through ShadowTr8ce, which combines deep- and dark-web intelligence with AI-assisted discovery to identify leaked credentials, exposed corporate information, stolen data, and threat-actor activity before they become larger business risks. AI accelerates discovery, while human investigators remain responsible for validation, context, conclusions, and testimony, ensuring defensible findings when the stakes are highest.

“Threat hunting is about answering a fundamental question: is there anyone in your systems who shouldn't be there?” says Sergio Kopelev, operating partner at AFIS. He joined AFIS to expand the firm's proactive cybersecurity services, particularly RogueHunter and ShadowTr8ce. Drawing on three decades of experience across law enforcement, Fortune 10 investigations, incident response, and cybersecurity consulting, he is helping make proactive threat hunting and information exposure monitoring, once reserved for organizations with six- and seven-figure budgets, accessible to small and midsize businesses through new technologies and strategic partnerships.

Supported by growing AI capabilities, strategic partnerships, and investigative rigor, AFIS continues expanding its ability to identify threats before they become crises. The firm's blend of forensic expertise, proactive risk identification, and evidentiary discipline has earned it recognition as one of the Top Digital Forensics Services Provider. The distinction reflects a mission that remains unchanged: helping clients uncover the truth before the consequences become irreversible.

Deep Dive

Selecting Digital Forensics Services for Defensible Evidence

Digital forensics has moved from a post-incident technical function to a board-level control point for litigation readiness and data protection. The modern enterprise stores evidence across laptops, mobile devices, cloud repositories, collaboration tools, and email systems, leaving organizations with limited visibility into relevant data when an urgent issue emerges. When an allegation of data theft, unauthorized access, insider misuse or credential exposure emerges, executives cannot rely on broad cyber-security reporting alone. They need findings that explain what happened, preserve the underlying evidence, support counsel and withstand scrutiny from regulators, insurers, courts or counterparties. The most effective forensic providers add value long before a full investigation becomes necessary. Employee departures, especially those involving executives or staff with access to confidential information, create a narrow window in which early review can prevent later uncertainty. A disciplined provider should help management teams identify whether files were copied, deleted, transferred to personal accounts or moved through external devices. That review should also account for cloud activity and unusual access patterns, because modern data movement rarely follows a single path. The value lies not only in detecting misconduct, but in separating routine business activity from behavior that warrants deeper inquiry. That distinction helps legal and security leaders avoid both underreaction and overreach. Defensibility is equally important. A forensic finding has limited value if the collection process, chain of custody, source handling or interpretation cannot survive legal challenge. Providers should be able to preserve data from varied sources, document each step and interpret artifacts in context. Reports must be clear enough for executives yet precise enough for counsel and expert testimony. This is where technical skill must be paired with investigative judgment. Automated tools can accelerate searching, filtering, clustering and anomaly detection, but human review remains essential when findings may influence employment action, litigation strategy, regulatory response or settlement posture. The procurement decision should also test how the provider communicates uncertainty. Digital evidence often contains gaps, conflicting timestamps, user behavior and system artifacts that can be read too broadly. A mature partner will state limits clearly and avoid converting incomplete signals into conclusions. "Effective Cyber Investigations Combine Technology, Human Judgment and Defensible Evidence." The same logic applies to external exposure. Data loss is no longer confined to systems controlled by the organization. Credentials, personal information, intellectual property and internal documents may surface across leak sites, criminal forums or other hard-to-reach online sources. A capable forensics partner should know how to search these environments and distinguish genuine exposure from noise after validating possible matches. Speed matters, but so does context. A false positive can waste legal and security resources, while a missed signal can extend business risk. Leaders should also expect cost discipline, since unfocused reviews can produce large bills without improving the quality of the decision. Advanced Forensic Investigative Solutions (AFIS) is a strong choice for executives that need digital forensics tied to practical risk decisions rather than generic incident reporting. It provides computer and mobile forensics, data preservation, IP theft investigations, unauthorized access analysis, log interpretation, eDiscovery and expert witness support. Its Departure Assurance Program addresses departing-employee risk through targeted early review, while RogueHunter reflects an assumed-breach approach to finding threats already inside the environment. ShadowTr8ce extends that discipline to deep and dark web intelligence, combining AI-assisted search with human validation. For organizations that need defensible findings and seasoned interpretation, AFIS Consulting merits serious consideration. ...Read more
