As policing continues to adapt to the realities of modern crime, digital forensics is facing increasing operational pressure. With discussions growing around a proposed national framework for digital forensics across UK policing, leading digital forensics consultancy SYTECH believes that while government programmes focused on governance, consistency and standardisation are both necessary and welcome, there is also a need to address the operational challenges facing forces today: scale, speed and technology capability.
Jessica Clewlow, Director at SYTECH, explains:
Frameworks, accreditation and clearer accountability are essential components of modern digital forensic capability – they protect evidential integrity, support public trust and ensure digital evidence can withstand scrutiny in court. However, governance alone will not resolve the systemic pressures now being experienced across digital forensic units.
The real challenge is volume and complexity. Investigators are now handling unprecedented quantities of digital evidence, increasingly sophisticated devices and growing expectations for rapid, actionable intelligence. Without a step change in scalable technology, automation and national infrastructure, backlogs and delays will continue to persist.
The opportunity now is to ensure that standardisation is matched by equivalent investment in infrastructure, technology and operational capability. The issue facing digital forensics is not simply one of governance and consistency, but of capability at scale.
When Standardisation Meets Operational Reality
Without parallel investment in infrastructure and capability, there is a risk that a stronger focus on frameworks and standardisation may not fully address the operational pressures facing digital forensic units.
Many police forces and agencies are now managing workloads at a scale far beyond what existing infrastructure was designed to support. Core IT systems and networks are struggling to accommodate multi-terabyte evidence flows; storage and computing resources are often fragmented across legacy systems; and the volume and variety of modern data constrain ingestion pipelines. At the same time, the expansion of frontline policing is driving a growing volume of digital evidence into the system, often faster than forensic processing capacity can keep pace.
Accreditation requirements such as ISO 17025 remain essential for maintaining evidential quality and integrity. However, they can also create operational challenges where forces lack the resources to deliver training, competency management and assurance at scale. As a result, tools such as frontline kiosks may be underutilised, with more devices routed back to already stretched forensic laboratories.
This highlights an important distinction: compliance and operational effectiveness are closely linked, but not always the same. A unit may have aligned processes, robust quality management and comprehensive audit trails, yet still experience significant backlogs if the underlying infrastructure cannot process evidence quickly enough. The result can be delayed investigations, extended bail periods and slower access to information that supports safeguarding and operational decision-making.
The Scale of Digital Forensics Has Fundamentally Changed
Digital forensics is now operating at a scale many existing processes and systems were never designed to support.
Investigations today routinely involve:
- Multiple devices linked to a single suspect or case
- Terabytes rather than gigabytes of data
- Cloud-based accounts, encrypted applications, IoT devices and rich media
- A growing frontline workforce empowered, and expected, to seize digital assets.
Alongside this, the volume of online offending is sharply rising. Agencies including the National Crime Agency and Internet Watch Foundation have reported sustained, double-digit increases in indicators linked to child sexual abuse material and other illegal content year on year. While precise figures vary between datasets and reporting periods, the broader trend is clear: more suspects, more devices, more data and greater investigative demand.
At the same time, much of the sector’s investment has understandably been directed towards governance, accreditation and framework development; however, there remains a wider discussion around whether equivalent long-term investment has been made in the operational infrastructure needed to manage this growth sustainably. Areas such as high-throughput evidence ingestion pipelines, scalable secure storage, and modern platforms capable of orchestrating workflows end-to-end are becoming increasingly critical to the effectiveness of digital forensic operations.
Against this backdrop, traditional “analyst-per-device” or “case-per-analyst” models are becoming progressively harder to sustain at scale, regardless of how well documented or governed those processes may be. Additional layers of process, oversight and alignment can improve consistency and reliability however, they do not resolve the underlying challenge created by exponential growth in data volume and complexity.
This is one of the key reasons why backlogs can persist even within well-governed environments. Process alignment can improve efficiency around the edges, but it cannot alone absorb the scale of modern digital demand. Sustained progress is more likely to depend on continuous investment in technology, automation and appropriately shared infrastructure capable of supporting the future needs of policing.
What Meaningful Transformation Could Look Like
Lasting improvements in digital forensics are likely to depend on a more scalable and technology-enabled operating model, with governance embedded from the outset rather than treated as a separate consideration.
This could include several key areas of focus.
Modern, Integrated Platforms
Many digital forensics environments still rely on multiple disconnected tools and manual handoffs between teams and processes. Greater integration across seizure, intake, analysis, review and disclosure could help to create more streamlined workflows capable of supporting higher data volumes and faster investigative timelines.
High-Capacity Infrastructure and Frontline Capability
As digital evidence volumes continue to increase, digital forensics increasingly needs to be treated as core operational infrastructure. Networks, storage and computing environments must be designed for high-volume forensic processing, while forces also need the training, competency management and oversight required to deploy kiosks and frontline tools safely and consistently at scale.
Automation and Advanced Analytics
Processes such as ingestion, de-duplication, routine processing, first-pass review and reporting can be streamlined through automation, allowing specialist investigators to focus on analytical judgement and investigative decision-making, rather than administrative workload. Carefully governed analytical and AI-enabled tools could also accelerate search, classification and pattern detection, augmenting specialist capability and reducing reliance on time-intensive manual review while remaining under human oversight.
National or Regional Infrastructure
There may also be value in exploring more regional or national approaches to digital forensic infrastructure, including shared processing capability, repositories and intelligence. This could help reduce duplication, improve resilience and avoid individual units trying to solve the same scale challenges independently, often with different levels of resource and maturity.
In this model, governance evolves too. Standards become more outcome-driven and technology-aware, defining the principles that must be upheld such as integrity, auditability, explainability and reproducibility, without unnecessarily limiting how innovation and modern technology can be used to achieve them.
Defining Success in Modern Digital Forensics
If the core challenge facing digital forensics is one of scale, and the infrastructure required to support it, then success may need to be measured not only by compliance, but also by operational outcomes, including:
- Time from seizure to meaningful result, including ingestion.
- Sustainable backlog reduction over time
- The proportion of cases where frontline tools such as kiosks and triage safely accelerate decisions
- Impact on safeguarding, charging decisions and investigative outcomes
Ultimately, the question is not simply whether processes are aligned, but whether policing is delivering faster, more effective justice and protection in an environment where digital evidence continues to grow in volume and complexity.
Governance should not act as a barrier to innovation, but as the framework that enables investment in the technology, infrastructure and operational capability needed to meet that challenge. The future of digital forensics will depend on how effectively these elements come together to deliver the speed, scale and resilience that modern investigations demand.
