Incident Response

When Seconds Count: Incident Response That Minimizes Damage

Incident response services provide rapid breach containment, digital forensics, and guided recovery when a security incident occurs. Vigil Cyber's incident response team works to minimize damage, preserve evidence for insurance claims and law enforcement, and restore normal operations — with response initiated within one hour of engagement.

Critical Window

What Happens in the First Hour, Day, and Week

Incident response is not one event — it is a structured sequence of actions executed against a ticking clock. Our team knows exactly what to do at each phase, because we have done it hundreds of times.

1H

The First Hour

Emergency triage call to assess scope and severity
Network isolation of affected systems to stop lateral movement
Preservation of volatile memory and log evidence
Initial attacker eviction and credential resets
Notification of key stakeholders and legal counsel
1D

The First Day

Full forensic disk imaging of affected endpoints
Log correlation to identify attack timeline and patient zero
Malware analysis and IOC extraction
Scope determination — what data was accessed or exfiltrated
Interim hardening measures for unaffected systems
Communication to regulators if required by law
1W

The First Week

Root cause analysis and full incident timeline
Clean rebuild or reimaging of compromised systems
Credential hygiene sweep across the entire environment
Vulnerability remediation that enabled the breach
Post-incident security hardening recommendations
Written incident report for insurance and regulatory use
Our Capabilities

Full-Spectrum Incident Response

From forensic investigation through recovery and hardening, our team delivers every capability your organization needs — without the overhead of building an in-house IR team.

Digital Forensics

Evidence Preservation and Analysis

Understand exactly what happened, when, and how — with court-admissible documentation.

Our forensic analysts image affected systems, reconstruct attacker activity from logs and artifacts, and produce a documented timeline of the breach. We preserve evidence in a format acceptable for legal proceedings, insurance claims, and regulatory investigations — protecting your organization from downstream liability.

Ransomware Response

Encryption Incident Management

Recover systems and data without paying the ransom — or make an informed decision if you must.

Ransomware response requires speed and precision. We identify the ransomware variant, assess decryption options, evaluate backup integrity, and manage recovery sequencing. When paying the ransom is unavoidable, we support the negotiation and cryptocurrency transaction process while maximizing the likelihood of functional decryption keys.

Recovery and Hardening

System Restoration and Security Uplift

Return to operations on a more secure foundation than you had before the incident.

Recovery is not just restoring backups. We validate backup integrity before restoration, rebuild compromised systems from clean images, and implement the security controls that would have prevented the breach. The post-incident environment is hardened — not just restored to its pre-breach vulnerable state.

Communication and Notification Support

Regulatory and Customer Communication

Meet legal notification obligations without creating additional liability.

Data breach notifications carry legal deadlines and evidentiary weight. Our team coordinates with your legal counsel to produce factually accurate breach scope assessments, supports the drafting of regulatory notifications to HIPAA OCR, state attorneys general, and SEC, and advises on customer communication timing and content.

Containment Strategy

Stop the Bleeding — Then Eliminate the Root Cause

Containment is not a single action. It is a sequence of coordinated steps executed to isolate affected systems without destroying the forensic evidence needed to understand the full scope of the breach. Move too fast and you destroy evidence. Move too slow and the attacker expands their foothold.

Our incident response team has built containment playbooks for ransomware, business email compromise, data exfiltration, and insider threats. Each playbook is adapted to your specific environment — your network architecture, your critical systems, your recovery time objectives.

Recovery is not complete when systems are restored. Recovery is complete when the root cause has been eliminated, the environment has been hardened against re-compromise, and your team understands what happened and why.

Containment Approaches We Deploy

Network Segmentation and Isolation

Isolating affected VLANs, subnets, or individual hosts to stop lateral movement while maintaining critical business operations on unaffected systems.

Identity and Credential Lockdown

Resetting compromised accounts, revoking active sessions, disabling suspicious service accounts, and enforcing MFA across the environment.

Command and Control Disruption

Identifying and blocking attacker C2 infrastructure at the DNS and network layer to sever the attacker's remote access to compromised systems.

Endpoint Isolation and Evidence Preservation

Taking affected endpoints offline in a forensically sound manner — preserving volatile memory and disk state for investigation while preventing further damage.

Communication Support

Breach Notification and Communication Support

How your organization communicates during and after a breach can be as consequential as the breach itself. Legal obligations, regulatory timelines, customer trust — all are in play simultaneously.

Breach scope assessment for regulatory notification thresholds
HIPAA breach notification to HHS Office for Civil Rights
State attorney general notifications under state breach laws
SEC material cybersecurity incident reporting support
Customer and employee notification letter review
Cyber insurance carrier breach notification coordination
Legal hold and evidence preservation guidance
Board and executive communication briefing support
Media statement review for factual accuracy

IR Retainer

A retainer means we are already familiar with your environment when an incident occurs. Onboarding documentation, network diagrams, and critical system inventories are on file. Response starts in minutes, not hours.

  • Pre-onboarded environment documentation on file
  • Guaranteed response time SLA
  • Priority escalation ahead of ad hoc engagements
  • Quarterly tabletop exercises included
  • Lower hourly rates than ad hoc response
  • Proactive threat hunting included

Ad Hoc Response

If you don't have a retainer in place and an incident occurs, we still respond. Ad hoc engagements begin with an emergency assessment call to scope the situation and deploy the appropriate resources.

  • No commitment required before an incident
  • Emergency assessment call initiated within hours
  • Full IR team mobilized based on scope
  • Written incident report delivered post-engagement
Report an Active Incident
