Cyber Incident Response Services

If you're dealing with an incident right now, call us. Our incident response team is available 24/7 to contain the threat, establish what happened and return your operations to a safe footing.

Whether you're facing ransomware, a data breach, business email compromise, malware, an insider threat or a cloud compromise, you'll work with experts who have handled it before.

 

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.

IR-CRA Camp_Posts_1

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.

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, unauthorized 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, unauthorized 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 organizations 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 prioritizes 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?
