What are Cyber Incident Response Services?
Cyber Incident Response services help organisations identify, contain, investigate and recover from cyber attacks and security breaches.
Integrity360 provides access to experienced incident responders, digital forensics specialists and cybersecurity experts who can rapidly establish what has happened, stop malicious activity, determine the extent of the compromise and support the safe restoration of affected systems.
Our Cyber Incident Response Team can support organisations remotely or on-site and is available 24/7 for both emergency incidents and retained Incident Response customers.
NCSC Assured Cyber Incident Response
Integrity360 is an assured provider under the National Cyber Security Centre's Cyber Incident Response scheme, which is designed to help organisations identify trusted providers of high-quality cyber incident response services.
NCSC assurance provides independent recognition of Integrity360's ability to support organisations facing significant cyber incidents, from initial investigation and containment through to forensic analysis, recovery and post-incident review.
By choosing an NCSC Assured Cyber Incident Response provider, organisations can have greater confidence that their response partner has been assessed against recognised standards for cyber incident response capability.
Integrity360 combines this assurance with 24/7 access to experienced Incident Response and Digital Forensics specialists, supporting organisations remotely and on-site when they need expert assistance most.
How our Cyber Incident Response works
When a cyber incident occurs, speed matters, but so does making the right decisions. Acting too quickly without understanding the situation can destroy evidence, disrupt critical systems or allow attackers to remain hidden within the environment.
Integrity360 follows a structured Incident Response process designed to help organisations rapidly understand what has happened, contain the threat and restore operations securely.
1. Triage and Initial Investigation
Our Incident Response team rapidly assesses the situation to understand the nature, severity and potential scope of the incident. We work with your teams to identify affected systems, gather available evidence and determine the immediate actions required.
2. Containment
Once the threat is understood, we take steps to limit its impact and prevent further attacker activity. This may include isolating compromised systems, disabling affected accounts, blocking malicious infrastructure or restricting access between parts of the environment.
Containment measures are carefully balanced against the need to preserve forensic evidence and maintain critical business operations wherever possible.
3. Digital Forensics and Investigation
Our specialists analyse forensic evidence from endpoints, servers, identities, networks and cloud environments to determine how the incident occurred and what the attacker did after gaining access.
This investigation can help identify the initial attack vector, compromised accounts and systems, attacker persistence mechanisms, data access or exfiltration, and the overall timeline of the incident.
4. Eradication
Once the scope of the compromise is understood, we help remove malicious files, attacker tooling, persistence mechanisms and compromised credentials from the environment.
The objective is not simply to stop the immediate attack, but to ensure the threat actor no longer has a viable route back into the organisation.
5. Recovery
Integrity360 works alongside your IT and security teams to support the safe restoration of affected systems and services.
Recovery activities may include validating systems before they return to production, monitoring for renewed malicious activity and helping prioritise remediation actions so business operations can resume safely.
6. Post-Incident Review
Following containment and recovery, we provide a clear assessment of what happened, how the incident developed and what can be done to reduce the risk of recurrence.
Findings can support internal stakeholders, insurers, legal advisers and regulatory requirements, while recommended remediation measures help strengthen security controls and improve future Incident Response readiness.
With Integrity360, you gain a trusted cybersecurity partner that will assess, contain and eliminate threats – ensuring a confident path to recovery.

Cyber Incidents we respond to
Ransomware Attacks
We help organisations respond to active ransomware incidents by containing affected systems, investigating attacker activity, identifying potential data exfiltration and supporting the safe recovery of business operations.
Data Breaches
Our Incident Response and Digital Forensics specialists investigate suspected or confirmed data breaches to determine how access was gained, what systems were affected and whether sensitive information may have been accessed, altered or stolen.
Business Email Compromise
We investigate compromised email accounts, fraudulent activity and identity-based attacks to establish how attackers gained access, identify affected users and help prevent further misuse of accounts or credentials.
Malware and Endpoint Compromise
Where malicious software or suspicious activity is detected, our specialists analyse affected endpoints and systems to identify malware, attacker tooling, persistence mechanisms and indicators of further compromise.
Cloud and SaaS Compromise
Integrity360 investigates suspicious or malicious activity across cloud environments, identities and SaaS platforms, helping organisations identify compromised accounts, unauthorised access and attacker activity.
Credential and Account Compromise
Compromised credentials can allow attackers to move through an organisation without deploying traditional malware. We investigate suspicious logins, account takeover and identity abuse to understand the extent of the compromise and contain further access.
Insider Threats
Our Digital Forensics specialists can investigate suspected malicious, unauthorised or high-risk activity involving employees, contractors or other trusted users while preserving the evidence required for further investigation.
DDoS and Disruptive Cyber Attacks
We support organisations responding to attacks designed to disrupt the availability of systems and services, helping assess the incident, coordinate containment and understand whether the disruption is part of a wider compromise.
Unauthorised Access and Network Intrusions
Where an organisation suspects an attacker may have gained access to its environment, Integrity360 can investigate systems, network activity, identities and forensic evidence to determine the scope of the intrusion and whether the attacker remains present.
Suspected Cyber Compromise
Not every incident begins with a confirmed breach. If unusual activity, unexplained alerts or suspicious behaviour suggests an environment may have been compromised, our Incident Response team can investigate and help determine whether malicious activity has occurred.

Incident Response FAQs
What is Incident Response (IR)?
Incident Response is the process of identifying, containing, investigating, and recovering from cybersecurity incidents such as malware infections, ransomware attacks, unauthorised access, and data breaches.
What does Integrity360’s Incident Response service include?
Integrity360 provides 24/7 incident response with expert-led containment, forensics, threat analysis, remediation guidance, and recovery support. The service includes remote and on-site support, detailed post-incident reports, and assistance with legal or regulatory obligations.
When should we engage an incident response team?
You should engage an IR team as soon as you suspect a breach or security incident—such as unusual login activity, ransomware, unauthorised system changes, or data exposure. Early containment reduces impact and speeds up recovery.
Do we need to be an existing Integrity360 customer to get help?
No. Integrity360 offers both retained IR services and ad hoc emergency response for organisations in need of immediate support—even if you’re not currently a client.
What is an IR retainer, and do we need one?
An IR retainer is a pre-arranged agreement ensuring rapid access to IR specialists in the event of an incident. It helps reduce response time, improve preparedness, and may include proactive services like tabletop exercises and threat hunting.
How fast can Integrity360 respond to an incident?
With a retained service in place, response can begin in as little as one hour. For ad hoc incidents, the team prioritises urgent triage and initial containment actions as quickly as possible.
Does the service include digital forensics and root cause analysis?
Yes. Integrity360’s IR service includes full forensic analysis to determine the source, impact, and scope of the incident—along with recommendations to prevent recurrence.
What makes Integrity360’s IR service different?
Integrity360 combines deep threat knowledge, rapid mobilisation, regulatory expertise, and tailored support. The service is backed by a dedicated IR team with real-world breach response experience and access to a 24/7 SOC.
