Incident Investigation

Cyber Incident Investigation

When a security incident occurs, understanding the full scope requires systematic investigation across systems, identities, and infrastructure — not assumptions.

When this service is needed

  • Suspected unauthorized access to systems or accounts
  • Unusual network activity or outbound connections
  • Reports of compromised credentials or data exposure
  • Security alerts indicating potential breach activity
  • Unexplained changes to system configuration or files
  • Ransomware or extortion-related incidents requiring scope assessment

What we investigate

  • Entry points and initial access vectors
  • Affected systems, accounts, and data
  • Attacker activity timeline and lateral movement
  • Persistence mechanisms and backdoors
  • Data access and potential exfiltration
  • Scope of compromise across the environment

Methodology

01

Scope

Identify potentially affected users, systems, and infrastructure.

02

Evidence

Collect logs, artefacts, and technical indicators from relevant sources.

03

Timeline

Reconstruct the sequence of events across systems and identities.

04

Root Cause

Determine how the incident occurred and what weaknesses were exploited.

05

Remediation

Guide containment and removal of attacker access and persistence.

Typical deliverables

  • Incident timeline and scope assessment
  • Technical findings report
  • Root cause analysis
  • Remediation recommendations
  • Evidence preservation guidance

Frequently asked questions

How quickly can an investigation begin?

For active incidents, initial scoping can typically begin once access to relevant systems and logs is established. The priority is preserving evidence while understanding scope.

Do you work with our existing security team?

Yes. Pratikar provides independent investigation expertise that complements internal teams, MSSPs, and legal counsel.

What if the incident is still active?

Active incidents require careful balance between containment and evidence preservation. We guide decisions to minimize further damage while maintaining investigability.
