What APPSEC does
APPSEC s.r.o. is a private Czech cybersecurity firm founded in 2016 and headquartered in Prague, operating as a project under AppToCloud.com. The company delivers a two-track security offering: Blackhat (offensive) services, including penetration testing, vulnerability scanning, and IT security training, and Whitehat (defensive) services, including information security audits against ISO/IEC 27001 and COBIT, security strategy creation, and executive training. A combined Blackhat & Whitehat test produces the proprietary APPSEC Tested certification with a star rating. All consulting services carry publicly listed CZK pricing, with penetration tests starting at 12,900 CZK and the combined test priced at 49,900 CZK.
Underlying the consulting practice is a proprietary vulnerability scanning engine built and maintained in-house, complemented by Python tooling used by the CTO for custom offensive security development. APPSEC also acts as an authorized regional reseller and implementer for four third-party security vendors: SentinelOne (next-generation endpoint protection), Cato Networks (SD-WAN with integrated cloud security), Clavister (network security appliances), and PhenixID (identity and access management). Distribution is direct, with no disclosed channel partners, and product pricing is not publicly listed.
The business model blends professional-services revenue from project-based consulting with subscription/recurring revenue from product distribution. APPSEC targets a horizontal segment of organizations of all sizes in the Czech Republic and Slovakia, with go-to-market executed through its website, a free security consultation funnel, and a newsletter. There is no disclosed external funding; the company is controlled by three co-founders, Pavel Krátký (CEO), Milan Bartoš (CTO), and Adam Paclt (also CEO of IceWarp and co-founder of AppToCloud.com and eM Client).
