Incident Response Services
At Trilight Security, we provide incident response services for organisations across the USA and the EU, including a strong focus on Germany. The average breach lifecycle in 2025 is 241 days — and organisations often have just four hours to respond before damage becomes irreversible. The difference between a $500,000 incident and a $5 million one is frequently determined in the first 24 hours. Our certified IR specialists contain active threats, conduct forensic investigation to establish root cause and scope, support regulatory notification obligations under GDPR, NIS2, and DORA, and produce the documented evidence chain that auditors, insurers, and regulators require. We also help you prepare before an incident occurs — through IR plan development, tabletop exercises, and IR retainer agreements that eliminate the critical delay of contract negotiation during a live attack.

Deliverables
- Incident Timeline Report: A chronological account of the complete incident — from first indicators of compromise through detection, containment, eradication, and recovery — with timestamps, evidence references, and documentation of every action taken.
- Root Cause Analysis: A detailed technical report identifying how the attacker gained initial access, what techniques were used, which systems were affected, and what data was accessed or exfiltrated.
- Forensic Evidence Package: Memory dumps, disk images, log extracts, network traffic captures, and other forensic artefacts preserved in chain-of-custody format for use in legal proceedings, insurance claims, and regulatory submissions.
- Regulatory Notification Documentation: Drafted notifications for GDPR, NIS2, DORA, HIPAA, and other applicable frameworks — including supporting evidence and timeline documentation required for supervisory authority submissions.
- Remediation Plan: A structured plan addressing every vulnerability and misconfiguration exploited during the incident, with specific recommended actions, timelines, and responsible parties.
- Executive Summary: A board-level summary of the incident — what happened, what was affected, what the response achieved, and the three to five most critical improvements required to prevent recurrence.
- Lessons Learned Report: A post-incident review document covering detection gaps, response effectiveness, communication quality, and specific programme improvements recommended for each phase of the response.
- Updated Incident Response Plan: Revisions to your IRP and playbooks incorporating lessons learned from the engagement, tested against the specific techniques used in the incident.

FAQ
Incident response is the structured process of detecting, containing, eradicating, and recovering from a cyberattack or security breach — minimising damage, preserving forensic evidence, and meeting the regulatory notification requirements that apply from the moment of discovery.
An IR retainer is a pre-negotiated agreement with an incident response provider that gives you guaranteed access to their team when an incident occurs — with priority response, pre-agreed rates, and typically annual readiness reviews. Without a retainer, finding a vendor and executing contracts during a live attack adds hours or days to your response timeline when every minute has financial consequences. Retainer clients resolve breaches 54 days faster than those without pre-established arrangements.
Under GDPR you have 72 hours to notify the supervisory authority of a personal data breach. Under NIS2 it is 24 hours for an early warning to the national CSIRT, 72 hours for full notification, and one month for the final report. Under DORA, the initial notification window is 4 hours for major ICT incidents. Missing these deadlines carries severe financial and reputational consequences regardless of how well the technical response was handled.
We respond to ransomware and extortion attacks, data breaches and exfiltration, business email compromise (BEC), phishing and credential compromise, insider threats, DDoS attacks, supply chain compromises, and any other security incident impacting your IT systems, cloud infrastructure, or operational technology.
Digital forensics is the systematic investigation and documentation of what happened during an incident — how the attacker gained access, what techniques they used, which systems and data were affected, and what evidence exists for legal and regulatory purposes. Forensic evidence preserved correctly during the incident is essential for regulatory submissions, insurance claims, legal proceedings, and preventing recurrence. Evidence destroyed or contaminated during a rushed response cannot be recreated.
Our ransomware response begins with immediate isolation of affected systems to prevent further encryption, followed by forensic preservation of affected systems before any remediation. We assess the ransomware strain, determine whether data exfiltration occurred, identify the full scope of compromise, and work with your legal team and cyber insurer on the ransom decision. We do not advise on paying — that decision requires legal, forensic, and insurance counsel. We focus on containment, evidence preservation, clean restoration from verified backups where available, and notification to applicable regulators and law enforcement.
Our incident response team is available 24/7. For IR retainer clients, response begins within the hour. For new engagements, we aim to have our team engaged and active within four hours of first contact. We establish an emergency hotline number for retainer clients so that incident notification never routes through a ticketing system.
Yes. We assist with drafting, reviewing, and submitting breach notifications under GDPR, NIS2, DORA, HIPAA, PCI-DSS, and other applicable frameworks. We provide pre-drafted notification templates as part of every retainer and IR plan engagement, and support the notification process in real time during an active incident.
A tabletop exercise is a structured, discussion-based simulation of a cyberattack scenario — bringing together your IR team, legal counsel, communications lead, and executive stakeholders to walk through how they would respond to a realistic incident. It tests whether your IR plan works in practice, exposes gaps in escalation paths and communication protocols, and generates the evidence of tested procedures that NIS2 and ISO/IEC 27001 auditors require.
MDR is a continuous, ongoing service — monitoring your environment 24/7 to detect threats before they become incidents. Incident response is activated when an incident has occurred or is actively in progress. The two are complementary: MDR reduces the likelihood and size of incidents; incident response contains and remediates them when they happen. Trilight Security offers both services.
Containment of an active incident typically takes 24–72 hours for straightforward cases. Full investigation, eradication, and recovery can take one to four weeks depending on the scale and complexity of the attack. Post-incident review and hardening activities extend the timeline further. We provide regular status updates throughout and a timeline estimate after the initial scope assessment.
Our incident response services satisfy requirements under GDPR, NIS2, DORA, ISO/IEC 27001, PCI-DSS, HIPAA, SOC 2, and other applicable regulatory frameworks. We provide the documented evidence chain — incident timeline, forensic findings, notification records, and remediation documentation — that auditors and supervisory authorities require.
