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.
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.
The First Hour

The First Week
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.
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.
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.
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
