Architecture of Invisibility
A guide to privacy, pseudonymity and OPSEC — in preparation, no checkout yet.
Products
E-books, checklists, technical materials, tools and other digital products developed around IT and cybersecurity.
Close-the-basics week
A free seven-day plan to close basic security gaps in a small firm: accounts, email, exposure, backup, vendors, and who answers the phone in an incident.
IR Desk
A free browser app for running an IR case: timeline, facts, hypotheses, decisions, gaps and Markdown export — nothing sent to the server.
SOC L1 Home Lab Checklist (product)
An extended paid SOC L1 lab checklist — in preparation. The free version lives under Resources.
DNS for one domain
Public records for one domain you own: MX, SPF, DKIM, DMARC, and records with no named owner. A note, not a host scan.
Hygiene 48h
A paid pack for an IT freelancer or a one-person firm: a 40-point checklist, a password policy, an incident card, prompts for your own exports, and a decision log.
Workshop quarter
One page from your answers about your own workshop: three gaps, three decisions, and the next quarter's date. No one else's target.
After your own secret leaks
The order for revoking a secret that left your repository, mailbox, or chat. A new secret at the issuer, not only a deleted line.
Baseline review
A fixed scope: one target (a domain, a code org, or mail), written permission from the owner, a report or an express note. 349 PLN gross, express 149 PLN gross.
Vendor access register
A register of firms that can reset your mail, domain, hosting, or accounting. Name, scope, end date, and how you revoke it.
Public repos of one organization
A review of up to ten public repositories in one organization you own. Paths that look like secrets, with no cloning of private repos and no exploits.
Start of client access
How to accept access to one client: a named account, an end date, a permission sentence, and no password in email.
One backup restore drill
A drill that restores one file from one backup, with a result date. Not a backup architecture for a whole company.
Domain loss card
The owner's order when a domain expires, DNS changes, or someone asks for a transfer code. Login only at your own registrar.
Close a client job
A close-out list for one freelancer job: access, links, the invoice, a password that arrived by chat, and the revocation date.
Invoice bank-detail change
A procedure for changing the bank account on an invoice: a second channel, a known number, two people, and what you do not confirm by email.
