After a breach, you need to know exactly what happened before you can report it or recover. Our investigators establish how the attacker got in, which systems and accounts they touched, and — crucially — what data was accessed or exfiltrated. We acquire and analyse disk, memory, cloud and log evidence under a documented chain of custody, then reconstruct a defensible timeline. The findings give your leadership, legal counsel and, where required, the Autoriteit Persoonsgegevens a clear, evidence-based account for GDPR breach-notification decisions.
When the risk comes from inside, discretion and rigour matter equally. We investigate suspected data theft, sabotage, policy violations and negligent handling by employees or contractors, working carefully to preserve evidence and respect employment and privacy law. By correlating endpoint, email, file-access and cloud activity, we reconstruct what an individual did and when, under a chain of custody that holds up in a disciplinary or legal setting. You receive a clear, factual report your HR, legal and management teams can rely on to act with confidence.
When an intruder reaches your network, we determine how they got in and everything they did next. Analysing firewall, proxy, VPN, endpoint and server logs alongside captured traffic, we identify the initial entry point, the lateral movement, the accounts and systems compromised and any persistence left behind. We map the activity to the MITRE ATT&CK framework so the story is clear and actionable. The output supports containment, eradication and hardening, and feeds directly into our incident response team when an active intrusion must be shut down fast.
Evidence increasingly lives on phones and in cloud tenants rather than on a single laptop. We perform forensic acquisition and analysis of iOS and Android devices and of cloud environments such as Microsoft 365, Google Workspace, AWS and Azure — recovering messages, app artefacts, access logs and audit trails while maintaining a defensible chain of custody. This is essential for investigating account takeover, business email compromise and insider activity. You receive clear findings and, where needed, expert reporting suitable for legal counsel, insurers or regulators.
