What BIT SENTINEL does

Bit Sentinel is an independent cybersecurity services company founded in 2015 in Bucharest, Romania, by CEO Andrei Avădănei, operating primarily across Central and Eastern Europe with global service delivery. The firm delivers professional penetration testing (network, application, mobile, wireless, IoT, DDoS, and now LLM/AI applications), SOC-as-a-Service with 24/7 monitoring, managed security, incident response and CSIRT, security code review, blockchain and smart contract security, and cybersecurity consultancy covering GDPR, NIS Directive, and financial-services regulations. Service delivery is direct enterprise field sales, low-volume, and partnership-oriented, with free retesting included in every pentest engagement.

The company has productized parts of its offering through three proprietary assets: FENDLY (vulnerability management), PhishEnterprise (automated security awareness and phishing simulation with gamification), and a custom-built SOAR platform layered over an Elastic SIEM deployment to automate SOC workflows. Integration coverage spans Azure Active Directory, Office 365, Fortinet/FortiGate, NetFlow, SIEM, and SOAR. The team holds 40+ certifications including OSCP, OSCE, CISSP, CISA, GPEN, and OSED.

Revenue mechanics blend one-time professional-services fees (penetration tests, code reviews, audits), subscription-based recurring streams (SOCaaS billed monthly by infrastructure or endpoints, annual incident response retainers), an outcome-based bug bounty pentest model, and a fixed-price Startup Security Essentials package. Customer mix spans large enterprises (Orange Romania, Alliance Healthcare, OMNIASIG, Fildas Catena Grup), SMBs, and early-stage startups in blockchain, SaaS, fintech, and telecom. Bit Sentinel is founder-owned and bootstrapped, with no disclosed external funding or institutional investors.
