Marcin Białczyk
Founder and Cybersecurity Operator at CHORS.NET. I help B2B companies understand where their infrastructure meets the internet, what risks that creates, and what to fix first. No scare tactics — only verifiable signals.
Who I am and how I work
CHORS.NET was built on a simple observation: most B2B companies do not need another jargon-filled report. They need visibility of what is already publicly visible: domains, DNS records, mail configuration, certificates, security headers, and basic misconfigurations.
My role combines business operations architecture with hands-on cybersecurity practice. I design processes where exposure screening, authorised vulnerability audits, and security status reports give management and technical teams a shared language for decisions.
I work remotely with clients in Poland, the United Kingdom, and the United States. Every engagement starts with a scope lock: what is included, what is not, and what a realistic outcome looks like.
What I do specifically
- 01. Internet exposure screening. A fast, non-invasive review of public attack surface: domains, DNS, mail, TLS, headers, common misconfigurations. No internal access required.
- 02. Authorised vulnerability audit. A deeper technical review of a specific domain, website, or application. Always after written client consent.
- 03. Security status report. A synthesis of screening, audit, and client data into a format both management and IT can use.
- 04. Prioritised recommendations. I do not deliver a list of 100 issues. I point out what to fix first to materially reduce risk.
What I do not do: I do not run full penetration tests as a standard service, promise "100% security", issue compliance certificates, or present invented case studies.
