About
Independent security expertise for businesses that run on Microsoft
Cyber Tom was founded on a simple idea: smaller businesses deserve the same quality of security work as large enterprises — without the enterprise price tag or the sales theatre.
Why Cyber Tom exists
Most small and mid-sized businesses now run almost entirely in Microsoft 365. Email, files, identities and devices all live in one tenant — which makes it the single most valuable thing an attacker can take over.
Yet most tenants are still running on default settings, with powerful security features already paid for but never switched on. At the same time, stricter rules from Google, Yahoo and Microsoft mean poorly configured email now simply doesn’t arrive.
Cyber Tom closes those gaps. We work directly with you, fix what matters most first, and leave everything documented so you stay in control.
How we think
What you can expect
Practical over perfect
The fix that gets done this week beats the perfect plan that sits in a drawer. We prioritise by real-world risk.
Evidence, not guesswork
Every recommendation is backed by what we actually found in your environment — with screenshots and settings to prove it.
Plain English
You should understand what we changed and why. If we can’t explain it simply, we haven’t understood it well enough.
Let’s talk.
A free 30-minute call. We’ll look at your Microsoft 365 tenant and email setup together and tell you honestly what needs fixing first — whether or not you work with us.
