It is a specialised service that helps organisations deal with cybersecurity incidents from start to finish. This includes immediate actions to contain and stop the threat, a thorough investigation to determine what happened (for example, how the attackers got in and what they did), and guidance on recovery and prevention. In essence, incident response and investigation provides expert help to manage a cyber crisis and prevent it from happening again.
We offer immediate support. As soon as you contact us about a potential breach, our team springs into action – day or night. We can begin triaging the situation quickly to limit damage. Our goal is to contain threats as quickly as possible, often within the first critical hours, and then work methodically to investigate the issue, returning with a completed investigation within two weeks (or even sooner, depending on the complexity).
Our comprehensive incident report details all findings and recommendations from the investigation. It contains an executive summary for high-level understanding, a detailed timeline of the incident, the scope of impact (which systems or data were affected), and root cause analysis (explaining how the incident happened). We also include clear recommendations for improving security, such as fixes and policy changes to prevent similar incidents. The report is written in plain language so both technical teams and executive stakeholders know exactly what occurred and what to do next.
We aim to minimise any disruption. In many cases, we can isolate and contain the threat without shutting down your entire operation. Our team works with your staff to quarantine affected systems and keep unaffected parts of your business running normally. If certain systems do need to be taken offline for safety, we will explain why and work as quickly as possible to get them restored. Throughout the response, we prioritise your business continuity – containing the incident in a targeted way and helping you stay operational wherever possible.
Absolutely. Our service does not stop at containment and analysis of the incident. After we have identified and eradicated the threat, we assist with the recovery phase – restoring data from backups, rebuilding or cleaning affected systems, and verifying that everything is secure. Beyond recovery, we provide post-incident support: we will recommend improvements, update your security measures, and even help retrain or brief your staff. The goal is not only to fix what happened, but also strengthen your defences against future attacks.
Having an incident response plan in place is highly recommended – it is like a fire drill for cyber emergencies. If you have one, we will follow and enhance your existing plan during our engagement. If you do not have a formal plan, do not worry. Part of our service is to bring structured response procedures to the table. We will quickly establish a plan of action when an incident occurs. After everything is resolved, we can help you develop a robust incident response plan for the future, using lessons learned from the experience.
We take a collaborative approach. Our incident responders integrate with your internal IT and security team, ensuring open communication throughout the process. We can lead the more complex forensic and remediation tasks, while your team provides valuable information about your systems and infrastructure. Think of us as an extension of your team during the crisis – we will guide and support your staff so that everyone remains coordinated and effective. We also help with communication to stakeholders (such as management or customers) as needed, aligning with your company’s communication policies.
We are equipped to handle a wide range of cyber incidents. This includes malware outbreaks and ransomware attacks, network intrusions, phishing schemes and business email compromise cases, insider threats, and large-scale data breaches. Our team has experience with both common and sophisticated attacks. Even if you are hit with a brand-new type of attack, our experts can adapt quickly. In short, if it’s a cybersecurity incident, we can help.
Yes. We understand that certain incidents may trigger legal obligations or regulatory notifications (for example, under Australian privacy laws or industry-specific regulations). As part of our incident response service, we help you navigate these requirements. We document evidence during the investigation in a forensically sound manner, which can support any legal proceedings or insurance claims. If needed, we can liaise with law enforcement or regulatory bodies on your behalf. Our comprehensive reports and expertise will also assist your legal counsel in understanding what occurred and determining next steps.
You can engage us in two ways. Many clients choose to sign up for an Incident Response Retainer in advance, which means our team is on standby and familiar with your environment before anything happens. Retainer clients receive priority response and peace of mind. However, if you are in the middle of a crisis right now, simply call us immediately at 1300 667 871 for emergency assistance. We will respond on the spot and begin helping you through the incident. We will arrange any necessary paperwork as we go – our top priority in an emergency is resolving the issue, and the formalities can follow.
