Cyber Incident Response Toronto — When Every Minute Counts
When you call us, you get experienced responders — not a helpdesk. We contain the damage, preserve the evidence, and get you operational again as fast as possible.
A cybersecurity incident — whether it's ransomware encrypting your files, a data breach exposing customer information, or a business email compromise draining your accounts — is one of the most disruptive events a business can face. The speed of your response directly determines how much damage you sustain.
The Cyber Arm provides 24/7 emergency incident response services to businesses in Toronto and across the Greater Toronto Area. We are on-call every hour of every day, and when you reach us, you immediately speak with an experienced security professional — not a helpdesk.

Our Incident Response Process
Contain First
Our first priority is stopping the spread. We isolate affected systems to prevent the incident from expanding to unaffected parts of your environment.
Preserve Evidence
We follow forensically sound procedures to preserve evidence throughout the response — critical if you need to involve law enforcement, your insurance provider, or legal counsel.
Investigate and Understand
We determine how the attacker got in, what they did, what data they accessed or exfiltrated, and how long they were in your environment.
Eradicate the Threat
We remove all traces of the attacker — malware, backdoors, persistence mechanisms — and remediate the vulnerabilities that allowed initial access.
Recover Operations
We support your recovery process, helping restore systems from clean backups, reconfigure security controls, and validate that your environment is clean before returning to full operations.
Post-Incident Report
You receive a complete incident report documenting the timeline, attack vector, impact, and recommended improvements — suitable for regulatory notification, insurance claims, and board reporting.
PIPEDA Breach Notification Requirements
Under PIPEDA, Canadian businesses are required to report data breaches to the Office of the Privacy Commissioner of Canada and notify affected individuals when a breach creates a real risk of significant harm. Failure to comply can result in significant fines.
Our incident response process includes guidance on your notification obligations and documentation to support the reporting process. We've helped Toronto businesses navigate PIPEDA breach notifications and understand exactly what must be reported, to whom, and within what timeframes.
