In the event of a cyber incident, every minute counts. Ransomware, data theft, compromised user accounts, or malware can have significant operational, financial, and regulatory consequences. A professional incident response helps companies respond to security incidents quickly, in a controlled manner, and in a way that is easy to track.
Incident response refers to the structured response to cyberattacks, security incidents, and compromised IT systems. The goal is to quickly contain attacks, minimize damage, and restore the secure operation of affected systems.
The Oneconsult International Computer Security Incident Response Team (OCINT-CSIRT) supports companies, government agencies, and organizations worldwide with:
Our goal is to quickly contain cyberattacks, professionally analyze digital traces, and securely restore affected systems.
Cyberattacks require quick decisions, clear responsibilities, and experienced specialists. Oneconsult combines incident response, digital forensics, and cyber crisis management into a single, integrated approach.
Our specialized DFIR team analyzes security incidents in a structured manner, coordinates technical and organizational measures, and reconstructs the sequence of events in a transparent way – and, if requested, in a manner that stands up in court.
In this regard, we support:
Cyberattacks happen unexpectedly. Customers with an Incident Response Retainer (IRR) benefit from the 24/7 availability of our incident response specialists. Drawing on our experience from over 800 incident response operations, we analyze, coordinate, and resolve cyber incidents quickly and efficiently.
In an emergency, every minute counts. We assist companies in the shortest possible time with technical analysis, containing the attack, and stabilizing affected systems.
Our DFIR (Digital Forensics & Incident Response) specialists combine incident response with forensic analysis to technically investigate attacks and determine the appropriate countermeasures. If necessary, digital evidence is secured in our lab in a manner that meets legal standards.
Our OCINT-CSIRT has many years of experience dealing with real-world cyberattacks, ransomware incidents, and complex security incidents. Our specialists hold certifications such as GCFA, GCFE, GDAT, GRID, GREM, and GCFR.
Our incident response and digital forensics investigations are conducted in accordance with established standards and best practices such as ISO/IEC 27035, ISO/IEC 27037, and NIST.
We treat all information, investigation findings, and security-related data as strictly confidential and in accordance with clearly defined security processes.
We do not consider a cyber incident to be merely an IT problem. Instead, as incident managers, we support and coordinate all stakeholders involved: management, communications, legal, and other members of the emergency or crisis response team.
After the incident response has been completed, we help companies improve their security measures, processes, and detection mechanisms to detect future attacks early and minimize damage.
Through rapid and structured action, we help reduce business disruptions, financial losses, and reputational risks.
Our incident response process follows a structured and proven approach to quickly contain cyber incidents, minimize damage, and securely restore affected systems.
Effective incident response begins before the actual incident occurs. We help companies prepare for cyberattacks – for example, with incident response plans, playbooks, and tabletop exercises.
In the event of an incident, we analyze the security incident, identify the affected systems, assess the extent of the attack, and define the necessary immediate measures.
The goal of containment is to quickly prevent the attack from spreading further, isolate affected systems, and minimize additional damage.
Our analysis provides helpful insights into the malware used, compromised accounts, persistence mechanisms, and other attacker activities within the affected environment, so that these can be effectively removed.
Following the cleanup, we assist with the secure recovery of the systems and a controlled return to normal operations.
Once the incident response has been completed, you will receive a detailed final report that includes technical findings and specific recommendations for action. In a joint lessons-learned workshop (retrospective/post-mortem analysis), we will analyze the incident together, identify opportunities for improvement, and develop targeted measures to sustainably enhance your cyber resilience.

The following information will help us conduct a quick and efficient initial assessment:
The more information we have at the outset, the more accurately we can assess the incident and recommend the next steps.
After a cyber incident is reported, the Oneconsult International Computer Security Incident Response Team (OCINT-CSIRT) works with you to assess the situation and determine the necessary immediate actions. We then initiate the incident response, analyze the incident, assist in containing the attack, and coordinate the recovery of affected systems.
Depending on the situation, we’ll provide support remotely or on-site. Our goal is to bring the incident under control quickly, minimize damage, and restore normal operations as soon as possible.
Effective preparation for cyber incidents involves organizational, technical, and personnel measures. These include, in particular, an incident response plan, clearly defined roles and responsibilities, documented escalation procedures, and regular drills and training sessions.
In addition, technical precautions such as centralized log management, monitoring, backup and recovery strategies, and regular reviews of incident response processes are recommended. Oneconsult supports companies in planning, implementing, and optimizing their incident response readiness.
The duration of an incident response operation depends on the nature, scope, and scale of the cyber incident. While minor security incidents can sometimes be resolved within a few hours or days, complex attacks or ransomware incidents often require an investigation lasting several days to several weeks.
Key factors for a rapid resolution include an early response, a structured incident response process, and the availability of relevant information and log data. The faster an incident is detected and investigated, the more effectively damage can be mitigated and systems restored.
Incident response should be considered whenever there are signs of a cyber incident. These include, for example, ransomware attacks, compromised user accounts, suspicious activity on systems, indications of data theft, or successful phishing attacks.
The sooner an incident is analyzed, the faster risks can be assessed, damage can be limited, and appropriate countermeasures can be implemented.
Yes. Depending on the nature and severity of the incident, we support companies both remotely and directly on-site. In the case of complex security incidents, on-site collaboration can help speed up decision-making and ensure that measures are implemented efficiently.
Yes. Early preparation can be crucial in an emergency. With Oneconsult’s Incident Response Retainer Services, companies benefit from designated points of contact, agreed-upon response times, and direct access to experienced incident response specialists.
This allows security incidents to be assessed more quickly, appropriate measures to be implemented sooner, and potential damage to be reduced. At the same time, companies with an IRR can continuously improve their incident response readiness and prepare specifically for cyber incidents.
With an Incident Response Retainer, companies benefit from rapid access to experienced incident response specialists, defined response times, and clearly established escalation and communication channels in the event of an emergency.
In addition, an IRR helps companies continuously improve their incident response readiness – for example, through workshops, drills, readiness assessments, or the optimization of existing incident response processes.
Yes. Our incident response and digital forensics specialists help companies analyze, contain, and resolve ransomware incidents. This includes, among other things, conducting a technical investigation of the attack, identifying affected systems and data, and assisting with the restoration of operations.
Availability Monday to Friday 8:00 a.m. – 6:00 p.m (exception: customers with SLA – please call the 24/7 IRR emergency number).
Private individuals please contact your trusted IT service provider or the local police station.
