What 17 53c does

17 53c is a Polish non-profit organization operating through a dual legal structure comprising a Foundation (Fundacja) and an Association (Stowarzyszenie), both unified under the 1753c.io brand. The Foundation is focused on building cybersecurity awareness, supporting knowledge exchange, evaluating technical and organizational solutions, and conducting research, while the Association concentrates on gathering knowledge, creating analyses and expertise, organizing conferences and meetings, supporting projects, and integrating cybersecurity experts. The organization serves Polish cybersecurity enthusiasts and professionals — ranging from students to experienced practitioners — through a community-driven model rather than commercial products.

Its core operational stack is a web-based platform (1753c.io) supplemented by a Discord community server, a monthly Meetup event series, and social media channels on YouTube, Facebook, and Instagram. Two offerings are publicly listed as "coming soon" on the website: structured cybersecurity courses (Kursy) and a CTF (Capture The Flag) team service for cybersecurity training. No proprietary software product, commercial pricing, or paid plans are offered; the organization does not sell software or services.

The business model is non-commercial. The organization is funded primarily through a Patronite crowdfunding partnership — a Polish patronage platform through which supporters contribute recurring donations in exchange for exclusive content access. There is no disclosed revenue, no funding rounds, no headcount, and no commercial revenue stream. The organization is member-driven and independently operated, with no disclosed parent company, institutional investors, or external ownership structure.

Recent moves6 records

Expansion highlights3 records

Emerging players

• Cybrary: Cybersecurity training and community platform. Comparable in the planned CTF/courses direction 17 53c is pursuing, though Cybrary is a venture-backed commercial platform.
• Women in Cybersecurity (WiCyS): Community-based nonprofit advancing cybersecurity diversity through events, conferences, and member programs. Comparable as a grassroots community-first model, though focused on a specific demographic mission.

Direct peers

• OWASP Foundation: Global open-source cybersecurity foundation with chapters and educational initiatives. Highly comparable as a nonprofit foundation driving community-led cybersecurity awareness, standards, and training.
• ISACA: Global professional association focused on IT governance, risk, and cybersecurity. Comparable as a membership-driven organization running conferences, research, and credentials for security professionals.
• Cloud Security Alliance (CSA): Membership-driven nonprofit organization advancing cybersecurity best practices and standards. Comparable as a member-and-research-led cybersecurity association hosting events and working groups.
• (ISC)²: International nonprofit professional association for cybersecurity professionals, offering membership, certifications, and community events. Directly comparable in mission and member-based engagement model.
• ISSA (Information Systems Security Association): Nonprofit membership organization for cybersecurity practitioners running local chapters, monthly meetings, and educational events — closely mirroring 17 53c's meetup-driven community model.

Broad incumbents

• SANS Institute: Largest cybersecurity training and research organization globally. Overlaps with 17 53c on training and community, but at vastly larger scale and with a paid commercial model.
• CompTIA: Large IT industry association offering certifications including Security+. Overlaps with 17 53c's educational objectives but covers a much broader IT scope with a commercial certification focus.
• EC-Council: Global cybersecurity education and certification body (e.g., CEH). Comparable in cybersecurity training focus, though operates as a commercial certification entity rather than a community foundation.
