Critical Digital Forensics & Incident Response | Diamond Cyber Security

Incident Response

Incident Response is the process of responding to and recovering from a cyber incident or attack. When your business experiences a cyber-attack or security breach it is critical to respond immediately. Diamond Cyber Security maintains a highly skilled Critical Incident Response Team (CIRT) staffed by experienced cyber operators capable of identifying, analysing, containing and eradicating cyber intrusions to your network.

The extent of the breach will determine the level of response. Your response must be thorough and effective, and reinstate confidence with investors, customers and regulators to show the business is taking steps to reduce any impact and provide a solution.

Our CIRT service provides the assurance businesses need to ensure continuance of operations even in the current high threat environment.

CIRT Capability

The CIRT capability is a structured response to addressing and managing a security breach or attack. Our goal is to handle the situation in a way that limits damage, reduces recovery time and controls the cost of recovery. The Diamond Cyber Security CIRT processes are drawn from the NIST 800-61 methodology.

During an engagement one of our experienced operators will be assigned to provide incident management, bringing together your internal staff, relevant third-parties and dedicated technical assistance from the CIRT.
