Frequently Asked Questions
22 years! S3 was founded by Marc, Vince, and myself in June 2003 after we all graduated in computer engineering together. Our vision was to become an outsourced IT department for SMBs which is still what we are today. We were, therefore, a Managed Service Provider before the term was used.
We are still the three sole owners of S3 and work hard at it every day.
Our typical client is an SMB based in the Greater Montreal, often with additional offices across Canada or the U.S. Many operate in a hybrid work model, and some are fully remote.
They all have in common that they take cybersecurity and employee productivity very seriously. They want IT to drive their business forward, not hold it back.
Our clients are in different industries:
- 60% are professional services firms
- 40% are in distribution or manufacturing
They all operate within the Microsoft ecosystem, using tools like Microsoft 365, Windows, and Azure. Most have a mix of cloud and on-premise infrastructure, while others are fully cloud-based.
We support two types of clients:
- Businesses without internal IT staff, where we act as their fully managed IT department
- Businesses with internal IT teams, where we work collaboratively with their IT team to extend their capabilities
Clients usually find us when they outgrow their IT provider or their IT team needs help.
