talk to an expert

Tenendo as a company consolidates extensive knowledge and rich hands-on experience of the best industry experts in a number of areas, ranging from offensive security to SecureSDLC and QA. The primary division of Tenendo is the Offensive Operations team, responsible for red teaming/adversary simulation and penetration testing. Its main focus is simulating an advanced threat by employing similar techniques and establishing analogous internal processes, such as:

  • A lot of time spent on internal research
  • An established private tooling development process
  • Additional attention is paid to social engineering, OSINT, or on-site activities that are usually left out-of-scope for compliance penetration tests
  • A demonstrated ability to simulate a known APT group

Tenendo employs experts in a number of offensive security fields that are capable of working both as a group or as a self-sufficient red team operator. We constantly develop our technical skills and undergo training and certifications, which include:

  • Offensive Security courses (OSCP, OSEP, AWAE, OSED, OSMR, OSWP)
  • Sektor7 malware and evasion development training
  • Pentester Academy and HackTheBox adversary simulation labs (CRTE, HtB Pro Labs 1-3)
  • Private social engineering and long-term offensive operation training from other experienced teams

We try to make sure our Offensive Operation team does not only provide excellent technical services but that the results make a measurable impact on the Customer’s security practices. Tenedo will conduct on-demand Purple Team exercises and provide consultancy for our red team operator to improve detection and monitoring. We are also open to sharing our private research with customers to ensure that they are adequately protected against emerging threats.
