Incident Response
Digital Forensics & Incident Response
We preserve relevant evidence, investigate what happened and support informed containment and recovery decisions.

The challenge
Early decisions shape the evidence
Early incident decisions can contain harm or erase the evidence needed to understand it. Digital forensics and incident response balances containment with evidence preservation, investigation and a controlled route back to operation.
From first report to informed recovery
Incident response organizes technical and business decisions when suspicious activity may affect systems, identities or data. Digital forensics examines available evidence to develop a supported timeline and scope.
Cyberus helps triage what is known, preserve relevant evidence and test incident hypotheses. Containment and recovery recommendations consider business impact, while final lessons focus on practical changes to controls and preparedness.
From alert to recovery decision
- Evidence held. Relevant records are kept intact so later conclusions rest on material that was not altered by early reactions.
- Analysis of scope. Timelines and hypotheses are tested to show which systems and accounts are involved and which are not.
- Containment choice. Options are weighed against evidence needs and business dependencies before disruptive steps are taken.
- Recovery decision. Restoration is staged and validated, so services return on the basis of what the investigation established.
Why it matters
- Business risk: Rushed clean-up can destroy the records needed to learn what happened, leaving leaders to recover without knowing what was touched.
- Decision it supports: Leaders can choose when to contain, what to restore first and what to tell stakeholders, based on evidence rather than assumption.
- What you receive: You receive a documented timeline, handling notes, stated uncertainty and prioritized improvements, within the agreed scope.
Support across the incident lifecycle
Triage and coordination
Clarify observed activity, immediate risks, decision owners and secure communication channels.
- Why it matters
- Early confusion about who decides and who is told slows every later choice and can widen the damage.
- Supports
- A clear decision owner and a safe channel for updates
Evidence preservation
Identify volatile and durable evidence, collection priorities and handling records.
- Why it matters
- Volatile data disappears quickly, and poorly handled records are hard to rely on if they are later questioned.
- Supports
- Defensible evidence for investigation, insurers or legal review
Host and account investigation
Examine relevant systems, logs and identity activity to test hypotheses and determine scope.
- Why it matters
- Knowing which hosts and identities were involved keeps response proportionate instead of broad and guesswork-driven.
- Supports
- A scoped list of affected systems and accounts
Containment support and recovery guidance
Present options, dependencies and evidence needs before disruptive actions are taken. Help define validation checks, monitoring and staged restoration for affected services.
- Why it matters
- Isolating the wrong system can alert an intruder or break a critical service, so options need their trade-offs stated. Restoring too early can reintroduce the problem, while restoring too late prolongs disruption.
- Supports
- Informed containment choices with known side effects; criteria for judging when a service is fit to return
Lessons learned
Document the timeline, decisions, control gaps and prioritized readiness improvements.
- Why it matters
- Without a written account, the same control gaps remain and the next incident starts from zero.
- Supports
- A prioritized list of logging and readiness improvements

Frequently asked questions
What should we do before contacting an incident responder?
Record what was observed, preserve relevant systems and logs where practical, use a trusted communication channel and avoid broad changes until evidence needs are considered.
Can an investigation always determine exactly what happened?
No. Conclusions depend on available and reliable evidence. Reporting should distinguish confirmed facts, supported assessments, unknowns and evidence gaps.
Who makes containment decisions?
Technical responders provide evidence and options, while authorized business and system owners decide actions that could disrupt services unless a plan assigns those decisions differently.
What happens after recovery?
A lessons-learned review should examine the timeline, decisions, control performance, logging gaps and specific improvements with accountable owners.
