What are Cyber Incident Response Services?
Cyber incident response services help your organization identify, contain, investigate and recover from a cyber attack or security breach.
You get incident response and digital forensics specialists who establish what has happened, stop the malicious activity, determine how far the compromise reached, and support the safe restoration of affected systems. They work alongside your team, on-site or remotely, and are available around the clock through our Canadian team and global SOC network for emergency callouts and for organizations with a retainer in place.
How the incident response process works
The incident response process runs in six stages, from triage through to post-incident review. Speed matters during an incident, and so does sequencing. Acting before the situation is understood can destroy evidence, take down systems the business still needs, or leave an attacker in place with a route back in.
From the first call, we work through the incident response process alongside your team, moving fast enough to limit the damage and carefully enough to preserve what you'll need afterwards for the investigation, your insurer and any regulatory reporting. You'll know what we're doing and why at each stage, including the decisions that affect your operations.
1. Triage and initial investigation
We start by establishing the nature, severity, and likely scope of the incident, working with your team to identify affected systems, gather available evidence, and agree on the actions that can't wait.
2. Containment
Once we understand the threat, we limit its spread and cut off further attacker movement. That can mean isolating compromised systems, disabling affected accounts, blocking malicious infrastructure or restricting access between parts of your environment. Every containment measure is weighed against preserving forensic evidence and keeping your critical operations running, and we talk through those trade-offs with you before acting.
3. Digital forensics and investigation
We analyze evidence from endpoints, servers, identities, networks and cloud environments to establish how the incident happened and what the attacker did with the access they gained. The investigation identifies the initial attack vector, which accounts and systems were compromised, any persistence mechanisms left behind, whether data was accessed or removed, and the timeline of events. We share what we find as the picture develops, so your decisions don't wait on the final report.
4. Eradication
With the scope established, we remove malicious files, attacker tooling, persistence mechanisms and compromised credentials from your environment. Stopping the immediate attack is the starting point. The work's objective is to ensure the threat actor has no viable route back in.
5. Recovery
Your IT and security teams work alongside ours to support the safe restoration of affected systems and services. Based on what your business needs running first, we agree on the restoration order, then validate systems before they return to production, watch for renewed activity, and sequence remediation so operations resume without reopening the same exposure.
6. Post-incident review
After containment and recovery, you receive an assessment of what happened, how the incident developed, and what would reduce the risk of it recurring. We walk your team through the findings and the decisions worth making next.
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
Containment comes first. We isolate affected systems, investigate attacker activity, identify potential data exfiltration, and work with your team to recover operations safely.
Data breaches
Our investigation establishes how access was gained, which systems were affected, and whether sensitive information was accessed, altered or exfiltrated, giving you the evidence your notification decisions depend on.
Business email compromise
Compromised mailboxes, fraudulent transactions and identity-based attacks are investigated to identify which of your users are affected and close off further misuse of accounts and credentials.
Malware and endpoint compromise
Where malicious software or suspicious activity is detected, affected endpoints and servers are analyzed for malware, attacker tooling, persistence mechanisms and indicators of further compromise.
Cloud and SaaS compromise
We investigate suspicious and malicious activity across your cloud environments, identities and SaaS platforms to identify compromised accounts and unauthorized access.
Credential and account compromise
Attackers holding valid credentials can move through an environment without deploying malware. We investigate suspicious logins, account takeover and identity abuse to establish the extent of the compromise and contain further access.
Insider threats
Where an employee, contractor or other trusted user is suspected of malicious, unauthorized or high-risk activity, we investigate while preserving forensic evidence to the standard your HR, legal or law enforcement process may later require.
DDoS and disruptive cyber attacks
When systems are deliberately taken offline, we help you assess the incident, coordinate containment with your providers, and establish whether the disruption forms part of a wider compromise.
Unauthorized access and network intrusions
If you suspect an attacker has reached your environment, we examine systems, network activity, identities and forensic evidence to determine the scope of the intrusion and whether they are still present.
Suspected cyber compromise
Not every incident begins with a confirmed breach. Unusual activity, unexplained alerts or behaviour that doesn't add up is reason enough to call. We investigate and establish whether malicious activity has occurred.
Speak to an IR expert
If an incident is underway, call now and we'll start immediately. If you're planning ahead, a response retainer puts agreed response times, a named team and pre-agreed terms in place before anything happens, so the first call isn't also a procurement exercise.
