The global cyber security market size was valued at $153.65 billion in 2022 and is projected to grow from $172.32 billion in 2023 to $424.97 billion in 2030. There’s a reason for this exponential growth. The 2023 World Economic Forum’s (WEF) Global Risks Report places cybersecurity in the current and future top ten risks globally, with the cost of cybercrime projected to hit an annual $10.5 trillion by 2025. Gartner analysts predict that over the next two years, 45% of global organisations will be impacted in some way by a supply chain attack. Cybercrime is big business, and so investing in the tools, solutions and skills to combat cyber threats has become big business too.
The question is, what is the foundation of true cyber resiliency in the face of this accelerating market, particularly when the threat is so asymmetrical? A threat actor just has to get through one vulnerability, but cyber security specialists need to rebuff hundreds or even thousands of attacks each year.
Which is where digital forensics plays such a vital role in overall security posture of an organisation. The good news is that cybercriminals and malicious attackers, like real-world offenders, leave a trail. At the heart of effective corporate governance and regulatory compliance, digital forensics allows organisations to identify, investigate, and resolve any suspicious or destructive activity, effectively responding to cybersecurity threats, investigating incidents, and maintaining the integrity of their digital assets. If you want to help your business to stay secure in today’s ever changing digital climate, working with a digital forensics partner is a key element in your overall cyber security strategy.
When are digital forensics necessary?
A digital forensics expert is usually brought in when an incident or breach has occurred. The forensics team will help to find, record and document evidence, which is then used in reporting to courts, filing insurance claims and preventing the attack from happening again.
For example, companies may need digital forensics in response to any of the following scenarios:
- Ransomware attacks
- Distributed denial of services (DDoS) attacks
- Trade secrets and intellectual property theft
- Disagreements at work
- Billing fraud, which is frequently enabled through phishing emails
- Inappropriate use of company assets
- Regulatory adherence / compliance
What is the value of digital forensics to your business?
Digital forensics is a complex field requiring specialised expertise. It is not just about having the right software tools; it requires a deep understanding of different operating systems, network protocols, and digital storage methods. A slight misstep can corrupt the data and the integrity of the investigation. Here are a few key ways that digital forensic partners add value to a business’s cyber security posture:
Cybersecurity and incident response: When a security breach occurs, a quick response is critical in order to regain operations and reduce the risk to your business’ reputation. When compared to conventional approaches, digital forensics has a substantially faster turnaround time in identifying the source of the breach, the extent of data compromise, and mitigating further damage. It allows organisations to respond swiftly, minimise downtime, and establish plans for recovery and future prevention.
Essentially, digital forensic experts search for evidence by looking for items including:
- Files that might be hidden, encrypted, or erased from the device
- Evidence of unauthorised access in system event logs
- Evidence of backdoors or rootkits installed on the system in question
- Unusual scheduled tasks set to run
- Instances of chosen keywords ran across all files on the system
Legal compliance and litigation: As data protection and privacy laws become increasingly stringent and with the Protection of Personal Information Act (POPIA) fully in effect in South Africa, organisations need to ensure they are prepared to conduct thorough investigations when required. Evidence from digital forensics can be used in court cases, for instance in proving data breaches or intellectual property theft.
Data recovery: Accidental deletions, system failures, or malicious activities can lead to data loss. A forensic approach helps recover this information while maintaining its integrity for use in legal proceedings if necessary.
Insider threat detection: Digital forensics isn’t just about external threats. It’s also instrumental in detecting insider threats. Whether unintentional (a disgruntled employee leaking sensitive information) or deliberate (malware installed on a company network), digital forensics tools can identify and trace such actions back to the source.
Preventing future attacks: The ability to find out why an attack or breach happened allows you to make proactive changes. Alternatively, your digital forensics partner can also work with you to put together a forensic strategy before an attack or breach does occur, helping you to review your data security and implement a policy to handle encountering legal privilege material or other sensitive data.
Working with the experts
Today, digital forensics isn’t limited to computers and networks—it extends to mobile devices, cloud platforms, IoT devices, and more. Each new tech frontier presents unique challenges that must be addressed to maintain robust and effective forensic capabilities. Within this digitally charged business environment, understanding and implementing digital forensics principles is no longer an option—it’s a necessity. Businesses that fail to recognise its value risk falling behind, suffering reputational damage, and potentially facing legal consequences. With an effective digital forensics strategy and partner, you can protect your digital assets but also build a stronger, more secure future.
