Incident Response
When a cyber security incident strikes, the speed and quality of your response determines the difference between containment and catastrophe. Cyse provides rapid-deployment incident response services delivered by experienced practitioners who have managed breaches across every major sector. From initial triage through to full forensic investigation and recovery, we work alongside your team to minimise damage, preserve evidence, and restore normal operations as quickly as possible.
What We Respond To
Our incident response team handles the full spectrum of cyber security incidents, from commodity malware through to sophisticated nation-state intrusions. Whatever the scenario, we bring structured, evidence-led response capabilities.
Ransomware & Extortion
Containment, negotiation support, decryption assessment, and recovery planning for ransomware incidents, including double-extortion and data leak scenarios.
Data Breaches
Rapid scoping to determine what data was accessed or exfiltrated, regulatory notification support, and evidence preservation for potential legal proceedings.
Business Email Compromise
Investigation of compromised mailboxes, forwarding rule abuse, invoice fraud, and lateral phishing campaigns targeting your employees and supply chain.
Advanced Persistent Threats
Detection, tracking, and eviction of sophisticated threat actors with long-term access to your environment, including nation-state and organised criminal groups.
Insider Threats
Investigation of malicious or negligent insider activity, including unauthorised data access, IP theft, sabotage, and policy violations with forensic-grade evidence collection.
Cloud & SaaS Compromise
Investigation of compromised cloud environments including IAM takeover, storage exposure, lateral movement across tenants, and supply chain compromise via SaaS integrations.
Our Incident Response Services
We provide end-to-end incident response capability, from proactive preparation through to post-incident recovery and lessons learned. Engage us before, during, or after an incident.
Emergency Incident Response
Rapid-deployment response to active incidents, providing immediate triage, containment, and coordination to stop the bleeding and stabilise your environment.
Digital Forensics
Forensic acquisition and analysis of endpoints, servers, memory, network traffic, and cloud artefacts to reconstruct the full attack timeline and determine root cause.
Malware Analysis
Static and dynamic analysis of malicious binaries, scripts, and implants to understand capabilities, persistence mechanisms, and indicators of compromise for threat hunting.
Threat Hunting
Proactive hypothesis-driven hunting across your environment to identify undetected adversary activity, dormant implants, and signs of compromise that automated tools miss.
IR Readiness Assessment
Evaluation of your incident response plans, playbooks, tooling, and team capabilities against real-world scenarios to identify gaps before an incident occurs.
IR Retainer
Pre-agreed retainer providing guaranteed response SLAs, pre-positioned tooling, and regular readiness activities so that when an incident occurs, we are already embedded.
Tabletop Exercises
Facilitated simulation exercises that test your organisation's response to realistic cyber attack scenarios, exercising decision-making, communication, and escalation procedures.
Recovery & Remediation
Guided recovery from compromised state to secure operations, including environment rebuild, credential reset, hardening recommendations, and monitoring deployment.
Post-Incident Review
Structured lessons-learned process delivering a comprehensive post-incident report with root cause analysis, timeline reconstruction, and strategic improvement recommendations.
Incident Response Lifecycle
Our response process is aligned to the NIST Incident Response Lifecycle and SANS frameworks, ensuring a methodical approach that maximises evidence preservation and minimises business impact.
Preparation
Establishing response capabilities, tooling, playbooks, and communication plans before an incident occurs. For retainer clients, this includes pre-positioned EDR agents and log forwarding.
Detection & Triage
Rapid assessment of alerts and reported anomalies to confirm whether an incident has occurred, determine its scope and severity, and mobilise the appropriate response resources.
Containment
Implementing short-term and long-term containment measures to prevent further spread, isolating compromised systems while maintaining business continuity where possible.
Investigation & Analysis
Deep-dive forensic analysis to determine the full extent of compromise, reconstruct the attack chain, identify the threat actor's TTPs, and collect indicators of compromise.
Eradication & Recovery
Complete removal of adversary presence from the environment, followed by controlled restoration of systems, credential resets, and deployment of enhanced monitoring and controls.
Lessons Learned
Formal post-incident review documenting root cause, timeline, response effectiveness, and actionable recommendations to strengthen defences and improve future response capability.
