Security, in plain English

The security gaps small firms are never told about

Big companies pay consultants to find these problems. Small firms usually find out the hard way — after the fraud, the leak or the hacked website. We check for them, explain what we find in plain English, and help you close the gap.

Start with email impersonation

What we check

Each check looks at something a criminal could already see from the outside, finds the real weakness, and gives you a plain report plus the option to keep watch. We never touch your website, your email or your settings — we tell you; you or your provider fix it.

Hacked website

Is your site quietly compromised — injected spam, hidden pages, a Google blocklist flag? We spot the signs from outside.

Exposed systems

Are databases, admin panels or backup files reachable from the open internet without you realising? We look for what’s left exposed.

How it works

Start with the one that costs businesses the most

“We’ve changed our bank details” scams cost UK victims £41.3 million in 2025 (UK Finance). A forged email in your name is invisible until it’s used — and simple to check.
