What CORESEC S.A. does

CORESEC S.A. (legal entity CORESEC A.E.) is a privately held Greek cybersecurity services firm headquartered in Athens, founded in 2012. The company provides B2B information security consulting to Greek businesses and organizations, offering a portfolio of nine core services: red teaming, vulnerability assessment, penetration testing (white box, black box, internal, external), DFIR (digital forensics and incident response), wireless network security testing, web application security testing, social engineering assessments, digital forensics investigation, and security awareness training. Engagements span targeted attack simulation, vulnerability identification, incident response, and human-factor security training, with services delivered by specialized engineers using both commercial and proprietary tooling.

The company's technology stack combines commercial security tools from leading international vendors with proprietary attack toolkits developed in-house by a dedicated Research and Development department. These proprietary tools target the detection and mitigation of unknown and emerging threats, including zero-day attacks. The firm references testing methodologies aligned with CWE Top 25 (2025), HIPAA Security Rule, NIST SP 800-53 Rev. 5, ISO/IEC 27001:2022, PCI DSS v4.0.1, SOX, and DISA STIG, indicating capability to test against frameworks used by regulated enterprises across multiple verticals.

CORESEC operates a sales-led, project-based professional services model. Engagements are consultative and quote-based, tailored to each client's specific requirements, with services delivered directly by specialized engineers without disclosed channel partners or resellers. The company markets primarily through its corporate website (coresec.eu), a long-running security blog featuring technical articles dating back to 2011, and direct consultation requests via contact form and phone. Operations are confined to a single country (Greece), the firm has 1-10 employees, and no external funding, partnerships, M&A activity, named customers, or management team details are disclosed in the available source material.
