Tenendo

🎉 Tenendo is 5! 🎉

When we started Tenendo in 2020, we had deep professional expertise – in offensive security, secure development, and compliance – but little business experience. We simply joined forces to build a company where top experts enjoy complex work, feel like family, and avoid the corporate noise.

Five years later, Tenendo is a trusted cybersecurity provider – from fintech to oil & gas, from startups to global telcos, from boutique consultancies to top QSA firms. Our services grew from basic testing to technical due diligence, multi-cloud and hybrid assessments, threat-led testing, adversary simulations, and custom R&D tooling.

Despite the changes, our core values stay the same:
✔️ We hire the best
✔️ We deliver high-quality work, on time
✔️ We keep learning, always

To our team, clients, and partners – thank you for five amazing years. Wishing you peace, health, and prosperity.

We rock.
Cheers!

Tight deadline? We can help.

Tenendo is rapidly expanding, increasing our ability to accommodate immediate complex projects. We are now able to offer extremely fast turnaround on:

— Application security projects (complex multi-platform application suites, critical APIs, mobile applications, etc)
— Threat-Led Pe*******on Testing (tailored to DORA/TIBER-EU) and regular scenario-based Red Teaming
— Pe*******on Testing with methodologies modelled for compliance or due diligence purposes (PCI DSS, SWIFT requirements or other regulations)

This is especially valuable for those who:
— Are preparing for a PCI DSS assessment or other audit
— Are facing DORA or local regulator-driven red teaming requirements
— Require a cybersecurity assessment as a part of a due diligence/acquisition process
— Have internal/executive deadlines creeping up fast
