From “nice to have” to necessity: Why digital forensics matters more than ever

By: Chad Gish – Magnet Forensics

One truth I’ve been emphasizing a lot lately at conferences and talks is just how important digital forensics has become.

When I first started in this field over 20 years ago with the Metro Nashville Police Department, digital forensics was more of a nice-to-have. If we could get to a phone or computer, great—it might help move a case along. But it wasn’t considered essential.

Over the years, that changed. After working thousands of violent crime and child exploitation cases, I can tell you firsthand—digital evidence is the key to unlocking the truth.

Messages, location data, deleted files, and timelines buried in those devices frequently reveal truths that would otherwise remain hidden. Again and again, that data helped us uncover the truth, protect victims, and bring closure to families.

Today, digital forensics isn’t a luxury. It’s a necessity.

It’s not just supporting the investigation—it is the investigation. Nearly every case today has a digital component, and if you don’t have the tools or training to uncover it, you’re already behind.

The difference between a solved case and a dead end often comes down to what you can recover and interpret from that digital footprint.

Steve Gemperle and I recently created a presentation called The 6 Pillars of Digital Evidence, which has become a popular topic at conferences. And when you look at these six sources of evidence, ask yourself—can you think of a modern investigation that doesn’t involve at least one of them?

• Physical devices – Mobile phones, laptops, computers, tablets, flash media
• Video – DVRs, doorbell cams, CCTV, highway cams, dash cams, BWCs, city/safety cams
• Call detail records (CDRs) – Timing advanced data, call, and text records
• Cloud content – Social media activity, device backups, email, location data
• Open-Source Intelligence (OSNIT) – Social media, public records, geospatial data
• Vehicle infotainment systems – Call logs, text, location data, vehicle system data

That’s why I’m so passionate about what I do now—helping agencies get the right technology into the hands of the people who need it most. Because I’ve seen the difference it makes when they have it.

And the consequences when they don’t.

Digital forensics is more accessible than you think

One of the biggest misconceptions I hear from agencies, especially smaller or rural ones, is that digital forensics is financially out of reach. And I get it. When people hear “forensics,” they often picture expensive wet labs, DNA sequencing, and highly specialized environments. But digital forensics isn’t like setting up a DNA lab.

Yes, there’s an investment, including tools, training, and sometimes infrastructure, but it’s far more attainable than many realize. In fact, many departments are already sitting on the most important piece of the puzzle: the digital evidence itself. Phones, computers, cloud accounts, and video are part of nearly every case.

The real question is whether you have the means to access and interpret it.

The good news? You don’t need a million-dollar lab to get started. There are scalable solutions—from extracting, to parsing and reporting—that can fit a wide range of budgets and agency sizes.

Grants can also help bridge the gap. 

And here’s the real kicker: this is the evidence every police chief, sheriff, and prosecutor wants early in the investigation. It’s often the fastest path to leads, suspects, and corroboration. But too often, agencies are forced to wait weeks, or even months, for an outside lab to process a device. In some cases, the devices don’t get prioritized at all. That kind of delay just isn’t acceptable anymore—not when the answers are sitting in the palm of your hand.

Digital forensics: Evolving from reactive to proactive

The demand for early access to digital evidence isn’t just a preference, it reflects how dramatically the field has evolved.

What once required specialized labs and days of manual processing can now be done in hours, and sometimes, even in real-time. The tools, techniques, and expectations have shifted so rapidly that digital forensics is no longer a back-end support role, it’s frontline investigative work.

To understand just how far we’ve come, and why every department, regardless of size or budget, needs to prioritize digital evidence, it helps to look at how the field has evolved over the last 15 years.

The evolution of digital forensics: 2010–2025

• 2010–2012: Early adoption phase
  • Digital forensics was seen as a niche specialty.
  • Focused mainly on computer hard drives.
  • Mobile forensics was limited and relied heavily on call detail records (CDRs).
  • Few investigators had formal training or tools.
• 2013–2015: Rise of the smartphone era
  • The explosion in mobile device usage changed the game.
  • Tools like Magnet IEF and Magnet Axiom have become staple forensic tools.
  • Call logs and photos became key evidence sources.
  • Social media data began playing a role in investigations.
• 2016–2018: Cloud and app data emergence
  • Investigators began targeting cloud backups (iCloud, Google).
  • Messaging apps became increasingly popular.
  • Agencies started building in-house digital forensics labs.
  • Encryption and locked devices became significant challenges: Graykey comes online to help with these challenges
  • Graykey has become a force to deal with encryption challenges.
• 2019–2021: Integration into mainstream policing
  • Digital evidence became central to nearly every case type.
  • First responders were trained to preserve digital evidence at scenes.
  • Cross-training between detectives and digital examiners increased.
  • Courts and juries began expecting digital evidence and metadata in trials.
• 2022–2024: Automation and AI assistance
  • AI tools began helping to triage and analyze large datasets.
  • Cloud-first forensics and remote acquisitions became more common.
  • Emphasis on speed: from weeks to hours for extractions.
• 2025 and beyond: A core investigative discipline
  • Digital forensics is now foundational, not optional.
  • Agencies are investing in full-time examiners and dedicated units.
  • Training and certification are becoming standard for investigators.
  • Digital forensics is integrating into other technical units, such as Real-Time Crime Centers, Cybercrime Centers, and Fusion Centers.
  • Real-time analysis and SaaS-based platforms—like Magnet Review—are becoming standard tools in modern investigations.

Real cases, real impact: The power of one artifact

If there’s any doubt about the value of digital forensics, just look at the That One Artifact series I’ve written for Magnet Forensics. Each blog highlights a case where one digital artifact—just one—either solved the case outright or significantly advanced the investigation.

In How Bluetooth Artifacts Cracked a Case, a single Bluetooth connection between a suspect’s phone and a getaway vehicle helped identify the make and model of the car, leading investigators directly to the suspect.

In Snapshot to Justice, an iPad Mini found at a crime scene held the key to solving the tragic murder of a child, despite being the only piece of digital evidence available.

Then there’s The Search History That Spoke Volumes—a case where a locked phone sat in evidence for months until access was finally gained. What investigators found was a search history so incriminating, it became the cornerstone of the prosecution.

And in How Cloud Forensics Revealed Evidence When Devices Didn’t, physical devices seized from a suspect’s home yielded almost nothing. But cloud data—retrieved through search warrants—contained thousands of disturbing search terms and images that directly tied the suspect to child exploitation. The breakthrough came not from the devices themselves, but from the suspect’s cloud activity, including a personal email login and search history placed him behind the keyboard.

These aren’t hypotheticals. They’re real cases, real victims, and real justice made possible by digital evidence. And they underscore a simple truth: every department needs the ability to access and interpret digital artifacts. Because sometimes, one artifact is all it takes.

Digital forensics is no longer optional

The journey from “nice-to-have” to necessity isn’t just a shift in mindset—it’s a reflection of how far digital forensics has come.

What was once a specialized, back-end discipline is now a front-line investigative tool that every department, regardless of size or budget, must prioritize. The evolution of tools, training, and accessibility has made it possible for agencies to act faster, dig deeper, and uncover the truth in ways that were unimaginable just a decade ago.

And the proof isn’t theoretical; it’s in the cases. From Bluetooth connections and search histories to cloud-based evidence and app data, digital artifacts have repeatedly delivered breakthroughs to solve a case, protect a victim, or bring justice to a family.

Digital forensics isn’t just part of the future of policing; it’s the present. The question isn’t whether your agency can afford to invest in it. It’s whether you can afford not to.
