Cornerstone Cyber secures identity, devices, data, and collaboration across Microsoft 365. We deliver secure by design solutions that are practical, repeatable, and built for impact. No fluff. No bloated decks. No tool pushing. Just real results from people who’ve run IT and cybersecurity from the inside.

We help internal teams unlock the full value of their Microsoft stack. Our services include health checks, zero trust architecture, Intune and Defender rollouts, Purview data protection, secure Teams collaboration, and full Microsoft 365 E5 activation. We also help teams modernise how they work, through structured intranets, Teams Voice, and intelligent access to business-critical content.

Every engagement is focused on execution. Our delivery is hands-on, fast, and documented. We don’t hide behind frameworks or drag out discovery phases. We show up, fix what’s broken, secure what matters, and leave you with clarity and control.

Our founders bring decades of experience across IT leadership, cybersecurity, and enterprise-scale projects. We’ve passed Nasdaq audits, built global IT from scratch, and led security programs that hold up to real scrutiny. We know what works, what’s noise, and what breaks under pressure.

We are not a reseller. We’re not chasing licence renewals or partner rebates. We are trusted advisors who build solutions that make sense, scale cleanly, and reduce long-term friction.

We work best with organisations who value substance over spin. You want to see outcomes, not hours. You want clear answers, not vendor waffle. And you want to move fast without compromising security.

If that’s you, we should talk.
