Incident Response

The structured process of containing, investigating, and recovering from a cybersecurity incident.

Also known as IR cyber incident response breach response

Incident response is the organized approach to handling cybersecurity breaches and attacks. Standard phases include preparation, detection, containment, eradication, recovery, and lessons learned. Speed matters: the faster a team contains an incident, the lower the financial and reputational damage.

Infostealer intelligence supports incident response by providing context on how attackers obtained access. If stealer logs show an employee's VPN credentials were sold two weeks before the intrusion, investigators can focus on that access path immediately rather than spending days on false leads.
