Are these really free?
Yes — completely free, no card, no login, no time-limited trial. We give them away because they're the same diagnostics our paid engineers run on Day One of an MSP engagement. If you like what you see, talk to us. If not, keep the report.
Will you spam me after I get the report?
No marketing automation. A real Drensys engineer reviews your scan and emails once if anything looks worth fixing. Unsubscribe by replying "no thanks" — that's it.
How accurate is this compared to a paid security audit?
These are surface-level passive checks — same signals you'd find in MxToolbox, Google PageSpeed Insights, or a SOC 2 questionnaire. A full Drensys assessment goes deeper (configuration review, internal scanning, employee training) but starts from these same findings.
Can I run these on a domain I don't own?
For email and SEO yes — they use only public DNS and HTTP data. The external security check requires you to confirm you're authorized to scan the target, because some businesses treat any external scanning as unauthorized testing.
What's in the personalized brochure you email me?
A full, branded report with every finding in plain English, business impact ("if you don't fix this..."), priority + effort estimates, recommended Drensys services that fit your specific findings, and a one-business-day expert review request form. PDF-downloadable.
Do you charge for the expert review?
No. 30 minutes with a Drensys engineer to walk through your report is free and there's no commitment. Pricing only comes in if you ask us to actually do work for you.
Skip the tools — talk to an engineer directly.
Tell us what you're worried about. A Drensys engineer will run the right checks for your business, walk you through the findings, and quote anything worth fixing. Free, no commitment.
