Case Studies
These case studies show the kind of work ITried does for Cape Town and South African SMEs: securing Microsoft 365, improving VoIP reliability, planning internet failover, and turning scattered IT problems into clear next steps.
Most IT problems are not isolated. A Microsoft 365 issue often touches DNS, email authentication, user access, devices, and security policy. A VoIP issue often touches fibre, firewall rules, Wi-Fi, failover, and call routing.
The case studies below are written as practical reading material. They explain the situation, what was at risk, what ITried checked, what changed, and why the outcome mattered to the business.
Some client details are anonymised. The aim is to show the business problem and technical approach without exposing private environments, users, suppliers, or internal systems.
Start with these two proof pieces. They match the core services ITried is positioning around: secure Microsoft 365 and reliable customer communication.
Microsoft 365 Security
A growing SME had Microsoft 365 working, but the tenant had grown through years of ad hoc changes. ITried reviewed users, admin roles, MFA, Exchange Online, SharePoint, Teams, Defender, and DNS records to give the business a cleaner security foundation.

A business with no fibre access relied on slow wireless and microwave links. ITried implemented SD-WAN to manage multiple weak links, prioritise VoIP and Microsoft 365, improve failover, and give the client better link-quality visibility.
