Sydney has 149 managed IT and cybersecurity providers with a local office, the largest base of any city on this site. Even so, a multi-office setup is comparatively less common here: 31 of the 149 run more than one location, a smaller share than in either Brisbane or Melbourne, reflecting how much of Sydney's supply is single-site operators serving the metro area from one base. Twelve Sydney providers hold a real, on-file ISO/IEC 27001 certification, more than any other city on this site, though as a share of Sydney's much larger total base it still sits below Brisbane's.
A local office matters most for on-site work; for anything delivered remotely, a provider based elsewhere can still serve a Sydney client well. If a certificate matters to your decision, filter for it below rather than taking a badge on a provider's own website at face value; this list shows only certificates MSP Pie holds a record for.
