What Securitum does

Securitum is a Polish cybersecurity services company headquartered in Kraków, founded around 2016 by Michał Sajdak. It self-describes as the largest pentesting company in Poland and operates through three legal entities: Securitum Audyty Sp. z o.o. Sp. k. for audits, Securitum Szkolenia Sp. z o.o. Sp. k. for training, and Securitum Wydawnictwo Sp. z o.o. for publishing (established 2023). The company claims 1,000+ commercial penetration tests performed annually, 8 years on the market, and a team of CISSP/CEH/OSCP/OSEP certified practitioners.

The company's service portfolio spans four product lines. The audit practice covers web application security audits (blackbox methodology), LAN network security audits, and social engineering (phishing) tests. The training arm runs Sekurak.Academy — a multi-tier annual subscription launched in 2023 with Standard, Starter, and Hacker (internship) tracks reaching 14,000+ participants — plus flagship courses including Websecurity Master (a 12-session advanced web security course) and Cyber Awareness training for non-technical office workers delivered through the Bezpieczny.securitum.pl sub-brand. The publishing arm produces Polish-language cybersecurity books, with the flagship 'Bezpieczeństwo aplikacji webowych' (Web Application Security) selling 15,000+ copies. The sekurak.pl knowledge portal functions as the company's content marketing engine and community hub, supported by a Discord community for training participants.

Securitum's revenue model combines professional services (penetration testing engagements, typically project-based in Polish złoty), recurring subscription training (Sekurak.Academy at 199-3,950 PLN per seat annually), corporate training packages (4,800-10,000 PLN for 10-25 seats with optional phishing tests), and one-time book/ebook sales (9.99-95 PLN). Go-to-market is hybrid: direct enterprise field sales for audits and corporate training, self-serve e-commerce via sklep.securitum.pl for individual learners, and community-led demand generation through sekurak.pl and Discord. The company is privately held with no disclosed external funding or institutional investors, and serves the Polish market with no stated international expansion.

Broad incumbents

• OffSec (Offensive Security): Established provider of offensive security training and certifications including OSCP. Comparable to Securitum's OSCP-certified team and advanced training offerings, but operating at much larger global scale as the benchmark credentialing body in pentesting.
• SANS Institute: Largest global provider of cybersecurity training, certifications (GIAC), and research. Comparable in breadth to Securitum's combined pentest, awareness, and technical training portfolio, but at vastly greater scale and price points.

Regional players

Direct peers

• Hack The Box: Global hands-on cybersecurity training platform with labs, academies, and corporate programs. Closely comparable to Sekurak.Academy's lab-based, community-driven IT security training model, though operating at much larger international scale.
• PortSwigger (Web Security Academy): Creator of Burp Suite and a free, deeply technical Web Security Academy covering OWASP Top Ten and advanced web vulnerabilities. Highly comparable to Securitum's Websecurity Master course, which also centers on OWASP-aligned web app security training.
• TryHackMe: Subscription-based cybersecurity training platform offering guided learning paths from beginner to advanced penetration testing. Directly comparable to Sekurak.Academy's tiered curriculum (Standard, Hacker, Starter) and Websecurity Master course structure.
• KnowBe4: Market-leading security awareness and phishing simulation platform. Directly comparable to Securitum's Cyber Awareness Training for office workers and social engineering test services (sklep.securitum.pl).
• PentesterLab: Subscription platform for hands-on web application and network penetration testing exercises with badge-based certification. Closely comparable to Sekuritum's lab-driven, practitioner-authored training methodology in the Websecurity Master course.
• INE Security: Provider of cybersecurity and IT training including penetration testing, web application security, and certification preparation. Comparable to Securitum's Websecurity Master and Sekurak.Academy enterprise training offerings, with overlapping instructor-practitioner positioning.

Others
