Digital Forensics & Incident Response
Investigate with Evidence. Respond with Control. Recover with Confidence.
When a cyber incident occurs, organisations need reliable facts and decisive action quickly.
Cyber Octet provides Digital Forensics & Incident Response services to help organisations investigate incidents, preserve critical evidence, determine the scope and root cause, support containment, and make informed recovery decisions.
Our structured approach combines forensic investigation, evidence preservation and incident response expertise to help organisations respond effectively while maintaining the integrity of critical evidence.
The Business Imperative
Poorly coordinated incident response can increase downtime, compromise valuable evidence and delay effective recovery.
A structured, evidence-led response helps organisations understand what happened, contain the threat, assess the impact and take appropriate corrective action.
Effective incident response requires three capabilities working together:

FAQ's
1. What is Digital Forensics and Incident Response (DFIR)?
DFIR helps organisations determine what happened during a cybersecurity incident, identify affected systems, understand the root cause, preserve digital evidence, contain threats and support secure recovery.
2. When should an organisation engage a DFIR or cyber incident response team?
- Unauthorised system access
- Malware infection
- Ransomware attack
- Data breach or data compromise
- Suspicious email activity
- Account compromise
- Security breach
- Other unexplained malicious activity
3. What types of Digital Forensics and cyber investigations do you provide?
- Cybercrime Investigation
- Digital Evidence Collection & Preservation
- Disk Forensics
- Memory Forensics
- Network Forensics
- Email Investigation
- Malware Analysis
- Ransomware Investigation
- OSINT Investigation
- Root Cause Analysis
4. How is digital evidence collected and preserved during a cyber investigation?
Appropriate evidence handling and collection records help document what evidence was collected, its source and how it was handled throughout the investigation.
5. What is the difference between Disk Forensics, Memory Forensics and Network Forensics?
Memory Forensics examines volatile system memory to identify malicious processes, activity and forensic artefacts that may not be available on disk.
Network Forensics analyses network communications and activity to identify suspicious behaviour, attack patterns and indicators related to a cybersecurity incident.
6. Can you investigate malware, ransomware and phishing emails?
Ransomware Investigation helps establish the scope, impact and possible attack vectors associated with a ransomware incident.
Email Investigation analyses suspicious emails, headers, attachments and associated evidence to identify potential phishing, compromise or malicious activity.
7. How do you determine the root cause of a cybersecurity incident?
The investigation can help identify the incident timeline, affected assets, Indicators of Compromise (IoCs), contributing security weaknesses and the likely root cause of the incident.
8. How do you support cyber incident containment and recovery?
Evidence-based recommendations are provided to limit further impact, securely restore affected systems and support informed recovery decisions.
9. What deliverables will we receive after a Digital Forensics or Incident Response engagement?
- Incident Assessment
- Digital Evidence Collection Records
- Digital Forensic Analysis Report
- Incident Timeline
- Indicators of Compromise (IoCs)
- Root Cause Analysis
- Affected Asset Assessment
- Malware Analysis Findings
- Containment Recommendations
- Recovery Guidance
- Executive Incident Summary
- Post-Incident Improvement Plan
10. How can DFIR improve cybersecurity after an incident?
Investigation findings can then be converted into corrective actions, stronger security controls and improved incident response procedures, helping organisations reduce the likelihood and impact of similar cybersecurity incidents in the future.
