I'm dj, based in Norwich. I built the tools that generate these reports to surface the security issues most small business websites have without realising it.
Most web developers focus on how a site looks. Security headers, CSP configuration, and transport policy are often left at defaults — which means they're often wrong. These aren't exotic issues. They turn up on most sites.
The audit is completely passive and free. I don't touch your server, I don't need any access, and there's no obligation. If something needs fixing, I can explain what it takes or point you in the right direction.
