What is Emergency Incident Response?
Emergency Cyber Incident Response provides immediate specialist support when an organisation is experiencing or suspects a serious cyber attack.
The objective is to rapidly understand what has happened, contain malicious activity, preserve evidence and prevent further damage while preparing the organisation for safe recovery.
Integrity360's Emergency Incident Response specialists can investigate active and suspected compromises, support containment decisions, conduct Digital Forensics and help organisations determine the scope and impact of an incident.
When Should You Call an Emergency Incident Response Team?
You do not need to know exactly what has happened before contacting an Incident Response provider. If there are signs that systems, identities or data may have been compromised, early investigation can help prevent a potentially manageable incident becoming a major breach.
Contact Integrity360's Emergency Incident Response team if you are experiencing or suspect:
Ransomware
Systems have been encrypted, ransom notes have appeared or there are signs that attackers may have stolen data before deploying ransomware.
Data Breach
Sensitive, personal or regulated information may have been accessed, downloaded or disclosed without authorisation.
Business Email Compromise
An email account has been compromised or impersonated, particularly where fraudulent payments or sensitive information may be involved.
Malware or Endpoint Compromise
Malicious software, suspicious processes or unexplained endpoint activity indicates that systems may have been compromised.
Account or Identity Compromise
Suspicious logins, stolen credentials or unusual account activity suggests an attacker may have gained access to legitimate identities.
Cloud Compromise
Unauthorised or suspicious activity has been identified within Microsoft 365, Azure, AWS or other cloud environments.
Network Intrusion
There are signs of lateral movement, unusual network activity or unauthorised access to internal systems.
Suspected Compromise
Something appears wrong but the cause is unclear. An investigation can determine whether malicious activity has occurred and whether an attacker remains present.

Emergency Incident Response FAQs
When should you call an Incident Response provider?
You should contact an Incident Response provider as soon as you suspect a significant cyber incident, particularly if ransomware, unauthorised access, compromised accounts, data theft or widespread malware may be involved. You do not need to know the full scope of the incident before seeking help. Early investigation can reduce further damage and preserve important forensic evidence.
What should I do first after discovering a cyber attack?
Start by escalating the incident internally and preserving relevant evidence. Avoid making unnecessary changes to affected systems until the situation has been assessed, as this can destroy forensic information. If possible, isolate clearly compromised systems and contact an Incident Response specialist to help determine the safest next steps.
Can Integrity360 help if we do not have an Incident Response retainer?
Yes. Organisations do not necessarily need an existing Incident Response retainer to request emergency support. Integrity360 can provide assistance to organisations experiencing an active or suspected cyber incident, subject to availability and the required engagement arrangements.
How quickly can an Incident Response team respond?
Response times depend on the nature of the incident, location and existing engagement arrangements. Organisations with an Incident Response retainer may benefit from predefined escalation procedures and response terms, helping specialists mobilise more quickly when an incident occurs.
What information should I have ready when calling an Incident Response provider?
Provide as much information as is currently available, including when suspicious activity was first identified, which systems or users appear to be affected, what alerts or ransom messages have been seen and whether critical services are disrupted. Do not delay contacting a responder simply because the full picture is not yet known.
What evidence should be preserved during a cyber incident?
Relevant evidence may include security alerts, system and authentication logs, suspicious files, emails, endpoint data, network activity, ransom notes and details of affected accounts or systems. Avoid deleting or modifying potential evidence before it has been captured, as this information can help establish how the incident occurred and what the attacker did.
What happens during an Incident Response investigation?
An Incident Response investigation typically involves triage, containment, forensic evidence collection, analysis of attacker activity, eradication of malicious access and support for recovery. The investigation aims to establish how the attack occurred, what was affected and what actions are required to remove the threat and reduce the risk of recurrence.
What is the difference between Emergency Incident Response and an Incident Response retainer?
Emergency Incident Response provides specialist support when a cyber incident is already happening or has recently been discovered. An Incident Response retainer is arranged in advance and establishes predefined contacts, commercial terms and response procedures before an incident occurs, helping reduce delays when emergency support is required.
