THANK YOU FOR SUBSCRIBING


Eric Mazur, Founder and PresidentAfter 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.

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.
What Do Digital Forensics Services Providers Do?
Digital Forensics Services Providers help organizations identify, preserve, analyze and present digital evidence during cyber incidents, fraud investigations, internal misconduct, intellectual property theft and litigation. Their work goes far beyond recovering deleted files. It includes protecting evidence integrity, documenting the chain of custody and producing findings that can withstand legal and regulatory scrutiny. As businesses rely more heavily on digital systems, dependable digital evidence has become essential for establishing facts and supporting informed legal decisions.
How Does Advanced Forensic Investigative Solutions Support Digital Investigations?
Advanced Forensic Investigative Solutions demonstrates the expertise organizations expect from trusted Digital Forensics Services Providers through computer forensic investigations, complex data collection, eDiscovery consulting and expert witness services. It follows repeatable, defensible evidence-handling procedures that preserve, process and analyze digital evidence for legal proceedings. Backed by decades of investigative experience across government and private-sector engagements, the firm's leadership combines technical expertise with investigative judgment to help clients navigate complex matters.
What Should Organizations Look for When Evaluating Digital Forensics Services Providers?
When evaluating Digital Forensics Services Providers, organizations should look for defensible forensic methods, careful preservation of metadata and chain of custody, along with experience supporting litigation and regulatory requirements. The ability to handle large and complex datasets, provide eDiscovery support and offer expert witness services can make a meaningful difference. Equally important is the ability to explain digital evidence clearly so attorneys, executives and courts understand its significance without losing critical context.
Why Is Evidence Preservation Critical During a Digital Investigation?
Experienced Digital Forensics Services Providers know that digital evidence is only useful if its authenticity can be proven. Proper preservation keeps original files, metadata, timestamps, cryptographic hashes, and a clear chain of custody safe before anything can be changed or lost. This careful process makes forensic findings more trustworthy and helps prevent arguments about evidence integrity, especially as AI-generated content and digital manipulation become more common.
How Do Digital Forensics Services Providers Assist in Litigation and Regulatory Matters?
The role of Digital Forensics Services Providers extends beyond identifying technical artifacts. They help legal teams interpret digital evidence through forensic reporting, eDiscovery support, evidence validation and expert witness services. Clear explanations of technical findings allow attorneys, investigators, regulators and courts to better understand what happened and how events unfolded. This support is especially valuable in matters involving data breaches, fraud, trade secret disputes or unauthorized access to sensitive information.
Why Is Advanced Forensic Investigative Solutions Featured Among Top Digital Forensics Services Providers?
Advanced Forensic Investigative Solutions reflects the qualities organizations expect from respected Digital Forensics Services Providers through its focus on defensible evidence collection, forensic analysis, eDiscovery and expert witness services. The firm handles complex investigations involving fraud, unauthorized data access, trade secret misappropriation and data manipulation while combining extensive investigative experience with legal and technical expertise. This balanced approach helps organizations manage digital evidence confidently throughout investigations and legal proceedings.
