Is Your Current IT Support Meeting Your Business Needs?
As your business grows, technology becomes more important — and more complicated. Reactive support, recurring issues and increasing cybersecurity risks can take time and attention away from running your business.
Third Octet helps businesses that:
- Have outgrown break-fix IT support or rely too heavily on one internal IT person.
- Need more reliable IT support and stronger cybersecurity.
- Want predictable IT costs without unexpected support bills.
- Need strategic IT guidance or additional expertise for an existing IT team.
Whether you’re looking to replace your current IT provider or get more from your existing IT resources, we can help.

Either way, you get one accountable IT partner focused on keeping your business running securely and reliably.

What is managed IT support?
Managed IT support is an ongoing service where an IT provider takes responsibility for managing, maintaining and supporting your business technology. This includes IT support, device management, cybersecurity, Microsoft 365 administration and infrastructure monitoring.
What is the difference between managed IT support and outsourced IT?
The terms are often used interchangeably. Managed IT support describes the ongoing management of your technology, while outsourced IT describes having an external provider take responsibility for some or all of your IT functions. Third Octet provides both fully outsourced and co-managed services.
Can you work alongside our existing IT team?
Absolutely. Our co-managed IT services provide additional expertise, cybersecurity support, technical resources and coverage for businesses with internal IT staff.
Do you provide cybersecurity as part of your services?
Yes. Cybersecurity is integrated into our managed IT services and can include endpoint protection, Microsoft 365 security management, email filtering, patch management and vulnerability management.
Do you provide onsite IT support in Toronto?
Yes. We’re based in Mississauga and support businesses throughout the Greater Toronto Area. Onsite support can be arranged when required, depending on your location and service agreement.
How much does managed IT support cost?
Pricing depends on your business size, number of users and devices, infrastructure, locations and support requirements. We provide transparent, predictable monthly pricing based on your actual environment. Visit our IT Support Pricing for more details.
