The firm's design-intensive applications (AutoCAD, Revit, Bluebeam, Adobe Creative Suite) were tied to office workstations. Remote access was unreliable. Support overhead was rising. Scalability was a guessing game. We deployed a dedicated physical server in our private cloud and configured Microsoft RDS for secure multi-user access — shifting the firm to a more agile IT model with centralized data, simpler support, and predictable costs.
Interlock's team has raised security awareness across our entire workforce. The platform, the phishing simulations, the reporting — it all works together. We've delivered nearly 19,000 training courses in 18 months and our people now recognize and report attacks before they cause damage.
We needed an IT partner who could speak to our ISO 27001 auditors and to our finance team in the same conversation. Interlock does both. Our reporting and security posture have never been clearer — and our auditors were impressed.
Since partnering with Interlock, we've seen a significant reduction in employees clicking malicious links, and our ISO 27001 evidence is easy to produce. Their security operations and training have become integral to how we manage risk across 25 business areas.
Most MSPs are run by salespeople. Interlock has always been run by engineers — people who answer to the work, not to a quota. If you call us, an engineer picks up. If we tell you something needs fixing, it's because it does. And if we're not the right fit for your business, we'll tell you that too.
