Incident Responder

Stop the damage, keep the evidence, and bring the business back.

An incident responder is the first call when something goes wrong: a compromised account, a malware outbreak, ransomware. The work combines calm decision-making under pressure with solid technical skills in logs, endpoints and cloud, and a habit of writing everything down.
