The scope is still unknown
Early alerts rarely show how the attacker entered, which systems are affected, whether access persists, or what data may be at risk.
CulperSec security services
Incident Response
Contain the incident. Establish the facts. Recover with a plan.
Support before, during, and after an incident
- Emergency response
- DFIR investigations
- Incident containment
- IR retainers
- Readiness exercises
The first hours decide how much uncertainty becomes damage.
Incident response requires technical investigation and disciplined coordination at the same time. CulperSec helps organizations stabilize the situation, establish reliable facts, recover securely, and prepare for the decisions that follow.
Evidence can disappear quickly
Routine system changes, rushed recovery actions, and incomplete logging can overwrite the artifacts needed to reconstruct the incident and support later decisions.
The business still has to operate
Containment, legal obligations, insurance coordination, customer communication, and recovery all compete for attention while facts are incomplete.
Engage now, or prepare before the call.
Choose event-driven professional assistance for an active or focused investigation, or establish an ongoing managed retainer for priority access and readiness support.

- Recovery and remediation guidance
Managed service
Incident response retainer
Establish the commercial, technical, and communication groundwork before an incident so your organization has priority access and a known response process when time matters.
- Priority access and contracted response terms
- Predetermined response hours
- Readiness assessments and planning
- Tabletop exercises and process validation
A response built around evidence and decisions.
The technical investigation matters, but so does the structure around it. Our responders help connect containment, forensics, recovery, and stakeholder needs throughout the engagement.
Establish command and communication
Create a working incident channel, identify decision-makers, align outside counsel and insurance contacts when applicable, and define the immediate objectives.
Give the response structure
Stabilize and contain
Identify immediate attacker access and work with system owners on containment actions that reduce further harm while considering business impact.
Limit additional damage
Preserve forensic evidence
Collect and protect relevant endpoint, identity, log, network, and cloud artifacts using methods appropriate to the investigation and potential legal needs.
Protect the factual record
Determine scope and root cause
Reconstruct the timeline, identify the initial access path, evaluate persistence, determine affected systems, and assess potential data exposure.
Replace assumptions with facts
Guide eradication and recovery
Support removal of malicious access, credential resets, secure restoration, validation, and the sequencing needed to return systems to operation safely.
Recover with confidence
Document findings and improvements
Provide an investigation record, key findings, response actions, and prioritized recommendations that strengthen readiness after the immediate incident ends.
Carry lessons forward
Move from uncertainty to controlled recovery.
Each incident is different, but a disciplined response follows a clear sequence that protects evidence, reduces harm, and keeps recovery tied to validated facts.
Engage
Confirm the request, establish secure communication, identify stakeholders, and collect the facts currently available without delaying action.
Stabilize
Assess immediate risk, preserve critical evidence, and coordinate containment steps that reduce active harm and attacker access.
Investigate
Analyze available telemetry and forensic artifacts to establish the timeline, root cause, scope, persistence, and potential data impact.
Recover
Guide eradication, credential and configuration changes, secure restoration, validation, and the monitored return to normal operations.
Improve
Document the incident, brief stakeholders, prioritize corrective actions, and update plans, controls, and detection based on what occurred.
Ready before the incident. Supported through recovery.
Whether the engagement begins during an emergency or through a retainer, CulperSec provides experienced response capacity while your organization retains the business authority and internal context required for critical decisions.
- Contain active threats with business impact in mind
- Preserve evidence before critical artifacts disappear
- Establish incident scope, timeline, and root cause
- Coordinate recovery around validated facts
- Support insurance, legal, and leadership communication
- Improve readiness through findings and exercises
Respond now, or prepare before it happens.
If you are experiencing an active or suspected incident, start the emergency intake. For retainers, planning, or non-emergency DFIR work, request a scoped conversation.
