What SiteCheck · CRM is and what it's for

Consulting CRM with a web security analyzer.

An IT consulting CRM whose jewel is SiteCheck: a real web security analyzer (HTTP, headers, TLS matrix, DNS/DKIM/DMARC, /.git and /.env exposure, malware scanner) with PDF audit reports.

The problem it solves

A consultancy needs to review the security of its clients' websites, but doing it by hand is slow and hard to repeat. There's no tool to automate the analysis and produce a presentable report.

How I approached it

I built a CRM with its own analyzer (SiteCheck): it checks TLS, headers, DNS/DKIM/DMARC and exposures (/.git, /.env), runs a malware scanner and generates PDF audit reports, with agentless multi-host monitoring.

Highlights

  • Real scanning of TLS, DNS, headers and exposures
  • Malware scanner with clean/suspicious/malicious verdict
  • Agentless multi-host monitor + PDF reports
