What Incident Response Delivers for US Enterprises

Incident response (IR) is a structured methodology for handling cybersecurity breaches — from initial detection through containment, eradication, and recovery. For US enterprises, effective IR must also satisfy regulatory obligations under SEC Cybersecurity Disclosure Rules (4-day reporting), CIRCIA (72-hour CISA notification), HIPAA compliance (60-day breach notification to HHS), and NYDFS 500 (72-hour superintendent notification). CyberSilo's ThreatHawk SIEM + SOAR platform provides the technology backbone for automated detection and response, while our certified incident handlers deliver on-site and remote support 24/7/365.

CyberSilo's incident response services are built for the US regulatory landscape. We handle everything from ransomware attacks and business email compromise (BEC) to nation-state intrusions and insider threats, ensuring every engagement produces admissible evidence and meets your specific compliance obligations — whether you operate in healthcare, finance, federal contracting, or critical infrastructure security.

Our IR retainer model gives enterprises guaranteed priority access to US-based incident handlers, with a contractual 15-minute SLA for initial contact and 60-minute SLA for active containment. Unlike firms that subcontract to overseas teams, CyberSilo maintains a fully US-licensed DFIR team with CISSP, GCFA, and CISA certifications, ensuring chain of custody and compliance with CIRCIA reporting requirements and federal evidence rules.

What CyberSilo Incident Response Covers

Six integrated capabilities that ensure rapid containment, thorough forensics, and regulatory compliance for every US enterprise engagement.

IR Capability 1

Rapid Containment & Eradication

Stop the breach within 15 minutes

CyberSilo's incident handlers deploy ThreatHawk SIEM + SOAR automated playbooks to isolate compromised assets, block C2 traffic, and remove threats at machine speed. Our average containment time is under 15 minutes, compared to the US industry average of 72 hours, reducing breach costs by up to $1.2M per incident.

Containment Actions
  • Network segmentation & host isolation
  • C2 infrastructure takedown
  • Malware removal & persistence cleanup
  • Account credential rotation
  • External threat takedown coordination

CIRCIA SEC HIPAA NYDFS 500
IR Capability 2

Digital Forensics & Investigation

Admissible evidence for litigation and regulators

Our GCFA- and GCFE-certified forensic examiners conduct disk forensics, memory analysis, network forensics, and cloud artifact examination using industry-standard tools (EnCase, FTK, Volatility, and CyberSilo's proprietary forensic platform). Every report meets Federal Rules of Evidence and regulatory standards for CMMC compliance, FedRAMP, and SEC investigations.

Forensic Capabilities
  • Disk & memory forensics (RAM dumps)
  • Network packet capture analysis
  • Cloud artifact recovery (AWS, Azure, GCP)
  • Timeline & root cause reconstruction
  • Chain of custody documentation

Breach Notification & Regulatory Reporting

Meet every US breach notification deadline

We prepare and submit breach notification packages for SEC (4-day Form 8-K), CIRCIA (72-hour CISA report), HIPAA (60-day HHS notification), NYDFS 500 (72-hour superintendent), and 50-state attorney general notifications. Our compliance team maintains templates and relationships with state AG offices to ensure timely, compliant submissions.

Notification Services
  • SEC Form 8-K materiality assessment
  • CIRCIA CISA incident report filing
  • HIPAA breach notification to HHS OCR
  • NYDFS 500 superintendent filing
  • Multi-state AG notification coordination

Ransomware Negotiation & Dark Web Intelligence

Reduce ransom payments and recovery costs

Our ransomware response team includes certified negotiators with law enforcement experience (FBI, Secret Service) who handle communication with threat actors, verify data exfiltration claims, and coordinate with insurance carriers. We also provide dark web monitoring through ThreatSearch TIP to detect leaked data and prevent secondary extortion.

Managed Detection & Response Integration

Proactive threat hunting paired with instant IR

CyberSilo's MDR services combine continuous 24/7 monitoring with instant IR escalation. When ThreatHawk SIEM detects anomalous behavior — from ransomware encryption to lateral movement — our SOC analysts validate and escalate to the IR team within 5 minutes, enabling sub-15-minute containment without requiring the client to self-identify the breach.

MDR+IR Integration
  • 24/7 SOC analysis with instant IR escalation
  • Automated playbook execution via SOAR
  • Threat hunting for zero-day and APT
  • Continuous compliance monitoring
  • Shared incident dashboard for CISO visibility

Post-Incident Remediation & Compliance Audit

Prevent recurrence and satisfy regulatory audit

After containment and eradication, CyberSilo delivers a comprehensive incident report with root cause analysis, remediation roadmap, and compliance gap assessment. We help you implement the controls needed to prevent recurrence and prepare for regulatory audits from HHS, SEC, or state AGs — with measurable KPIs and timelines.

Remediation Services
  • Root cause analysis report
  • Remediation roadmap with SLA tracking
  • Compliance gap assessment & remediation

What Poor Incident Response Coverage Costs US Enterprises

Without a dedicated incident response retainer, US businesses face exponentially higher costs, regulatory penalties, and reputational damage. The numbers speak for themselves.

$4.5M

Average Breach Cost — US Enterprises

IBM's 2025 Cost of a Data Breach report shows the average US breach costs $4.5M, 30% higher than the global average. For healthcare organizations, the figure rises to $9.48M. Organizations with an IR retainer save an average of $1.2M per incident compared to those without.

277

Average Dwell Time — Days Unnoticed

The average time to identify and contain a breach in the US is 277 days (IBM 2025). During this period, attackers exfiltrate data, establish persistence, and move laterally. CyberSilo reduces dwell time to under 6 hours through integrated MDR and IR.

$5.6M

SEC & FTC Penalties for Delayed Reporting

The SEC has fined companies up to $5.6M for failing to disclose breaches within 4 days (Form 8-K). FTC enforcement under GLBA Safeguards has resulted in penalties of $1.5B+ combined. CIRCIA imposes fines of up to $1.1M per day for non-compliance with 72-hour reporting.

82%

Breaches Involving Cloud Assets — Without Forensic Coverage

82% of US breaches involve cloud-stored data (IBM 2025), yet most legacy IR providers lack cloud forensic capabilities. CyberSilo's cloud-native DFIR team recovers artifacts from AWS, Azure, and GCP — ensuring you can meet HIPAA and SEC evidence requirements even for cloud-only incidents.
