Working with us
Our response process
Our team are ransomware recovery specialists with a proven, streamlined approach to resolving incidents quickly and effectively.
Step 1: Triage
We respond the same day you call. Our incident managers quickly assess the situation, establish secure communication channels and gather key information. This allows us to prioritise actions, stabilise affected systems and begin containment immediately.
Step 2: Investigation
Our Digital Forensics and Incident Response (DFIR) team identifies how the attack occurred, what systems were compromised and whether any data was accessed or exfiltrated. We preserve forensic evidence to support insurance, legal or regulatory processes.
Step 3: Contain
We isolate infected devices, remove malicious code and block attacker access. This step prevents further spread and ensures your unaffected systems remain operational while recovery work begins.
Step 4: Remediate & Eradicate
Once the threat is contained, we fix the weaknesses that enabled the attack. This includes patching vulnerabilities, restoring clean system images and strengthening access controls to prevent re-entry.
Step 5: Recover
We restore data, applications and infrastructure in a secure, staged process. Our goal is to get your business operational as quickly and safely as possible, with full verification that systems are clean and stable.
Step 6: Post Incident
After full recovery, we review the incident in detail, identify root causes, assess response effectiveness and recommend measures to improve your resilience.
