24/7 Cyber Incident Response  

For immediate support, Deloitte’s cyber specialists are on call.

Our NCSC accredited Cyber Incident Response and Forensics service is a 24/7 standby service for cyber incidents or data breaches. Our call handlers will connect you to a cyber specialist first responder by telephone to assess the support required. We are bound by confidentiality and you have no obligation to proceed.

We’ll deploy specialists as quickly as we can from our global network; normally within hours of your initial call. The speed of response is often crucial to limiting brand damage. Our specialists are skilled and practiced at scoping and sizing an incident for technical analysis, containment, and immediate remediation.

We work alongside other Deloitte specialist services including Crisis Management and Communications, Technology Recovery, and Customer Breach Support. Where the initial evaluation identifies these services are needed, they can be deployed within hours to support the recovery.

If you are experiencing a cyber incident, please call us on our 24/7 hotline for immediate advice and assistance from our cyber specialists.

Who are we?

Our experienced Cyber Incident Response team are full time Deloitte employees from our UK and global network. Our retained clients have response Service Level Agreements in place and we work with them regularly to understand their business and risks. We also regularly help non-retained organisations on a ‘walk-in’ basis. Our responders bring their practical hands-on experience to response situations, to help our clients better prepare themselves for cyber security incidents; reducing internal response times and building capability.

What are we asked for most in CIR and what are we best at?

No two incidents are the same, but there is some commonality in the types of support asked for by our clients. The following are the activities we are best practiced at:

  • Cyber Incident Management – Reducing the impact of an incident through efficient, coordinated, and structured management including activity prioritisation, work stream design, resolver team management, and senior stakeholder liaison and communication. 
  • Network Forensics – Analysis of network traffic to detect, understand, and analyse anomalous activity for indicators of compromise and active adversaries. 
  • Endpoint Forensics – Examination of endpoints to collect, preserve, and analyse information or evidence gathered from applications, memory, and files.
  • Malware Analysis – Analysis of executables, scripts, or known malicious software to understand their purpose and identify malicious activity through dynamic and static reverse engineering.
  • Log File Analysis – Investigation of logs from existing sources to detect anomalous activity and identify indicators of compromise.
