Digital Forensics & Incident Response (DFIR)
Respond quickly, recover safely, and understand what really happened with full forensic investigation and incident response support.
About Service
DFIR Overview
When a cyber incident strikes, every minute matters.
Data disappears, attackers hide their tracks, and systems become unstable. Without the right expertise, small issues turn into major breaches.
This is where Digital Forensics & Incident Response (DFIR) becomes essential.
CyberXSoft helps organizations contain attacks, investigate what happened, identify affected systems, and guide recovery with clarity. Our incident response team works step-by-step to ensure evidence is preserved, attackers are removed, and operations return to normal safely.
Our goal is simple: stop the attack, understand the root cause, and prevent it from happening again.
What Is DFIR?
DFIR combines forensic analysis and incident response to answer the most important questions after an attack:
- How did the attacker get in?
- What systems were affected?
- What data was accessed or stolen?
- Are they still inside the environment?
- How do we stop and remove them safely?
Through forensic investigation, log analysis, malware review, and full compromise assessment, DFIR gives your team the truth — not assumptions.

Tools Commonly Used in DFIR
Here are tools widely used across the DFIR industry (we may use some depending on the engagement):
Forensic & Evidence Collection Tools
- FTK Imager
- EnCase Forensic
- Autopsy / Sleuth Kit
- X-Ways Forensics
Endpoint & Incident Response Tools

These tools help uncover attacker behavior, reconstruct timelines, and preserve evidence for investigations.
Real Threat Scenarios Where DFIR Helps
- Unexplained system slowdowns or suspicious account activity
- Files being encrypted or deleted without reason
- Unauthorized logins from unknown locations
- Strange processes running on endpoints
- Sensitive data appearing to be accessed or exfiltrated
- Unexpected privilege changes or new admin accounts
- Alerts from SOC that require deeper investigation
- Systems showing signs of malware or backdoors
These situations require immediate DFIR action — not assumptions or delays.
Common Use Cases for DFIR Services
Organizations typically rely on DFIR when they face events that require fast investigation, clarity, and expert decision-making. Some practical scenarios include:
Suspicion of Unauthorized Access
Unrecognized logins, password resets, unusual user behavior, or unexpected admin accounts often signal a compromise that needs immediate verification through a compromise assessment.
Ransomware or Malware Infection
When files are encrypted, systems slow down, or suspicious processes appear, DFIR helps determine the infection method, affected assets, and safe recovery steps.
Data Exposure or Potential Data Theft
If confidential data is accessed or transferred unexpectedly, DFIR conducts breach analysis services to confirm what was viewed, copied, or exfiltrated.
Unexplained System or Network Activity
Sudden traffic spikes, unknown connections, or new scheduled tasks often require forensic investigation to understand whether an attacker is active.
SOC Alerts That Require Deep Analysis
When SOC or SIEM alerts point to suspicious patterns but lack clarity, DFIR validates whether the threat is real and identifies its root cause.
Compliance or Legal Requirements After an Incident
Regulated industries often require detailed investigations and the preservation of evidence. DFIR ensures proper documentation for legal, compliance, or insurance needs.
Post-Incident Verification Before Returning to Normal Operations
Before systems go back online, DFIR helps ensure no backdoors, persistence mechanisms, or hidden attacker activities remain.
How Our DFIR Process Works
1. Initial Incident Call
We gather critical information, validate the alert, and set the response plan.
2. Containment & Isolation
We stop further damage through isolation and temporary control measures.
3. Evidence Collection
We capture logs, disk images, and memory safely for investigation.
4. Deep Forensic Analysis
We identify attacker actions, movement, and techniques.
5. Remediation Planning
We guide your team on removing the threat completely.
6. Final Reporting & Hardening
You receive a detailed breakdown of what happened and how to prevent recurrence.
Who Can Benefit From DFIR?
- Companies experiencing a suspected or active breach
- Organizations needing clarity after a security incident
- Teams without an internal incident response team
- Businesses required to produce forensic evidence
- Companies preparing for regulatory reviews
- Teams wanting a complete compromise assessment
- Organizations that need fast recovery and guidance
Stop the attack. Find the truth. Recover with confidence.
Your incident deserves expert handling.
FAQ
Frequently Asked Questions
How do I know if I need DFIR services or if it’s just a false alarm?
If you notice unusual account activity, unauthorized access, system slowdowns, or suspicious files, DFIR helps validate whether an incident is real. Early involvement prevents attackers from hiding their tracks and helps avoid a larger business impact.
Can DFIR be performed if systems have already been rebooted?
Yes, but evidence may be partially lost. Our DFIR services can still recover logs, remnants, and artifacts needed for accurate investigation. Memory captures are ideal, but disk analysis and log reconstruction remain effective even after a reboot.
How fast can your incident response team start working?
In most cases, we begin within hours. A fast response is critical because attackers often escalate their access. Our incident response team prioritizes quick validation, containment, and preservation to prevent further damage.
Will forensic investigation disrupt business operations?
No. Most collection and analysis processes run in the background. We avoid downtime unless a device is severely compromised. Even then, we guide you toward safe, minimal-impact isolation.
What is included in a compromise assessment?
A compromise assessment checks if attackers gained access, moved laterally, created backdoors, or stole data. It includes account reviews, log analysis, traffic inspection, and system validation to determine the full impact.
Do organizations need DFIR even if the attack seems small?
Yes. Minor incidents often reveal larger unseen problems — such as unpatched systems or stolen credentials. Breach analysis services help uncover hidden risks and ensure attackers haven’t left persistence behind.
