We simulate real threats. You build real resilience



Targeted adversarial testing, continuous attack simulation, and advanced red teaming — for organizations that take cybersecurity seriously.


25+ years of experience in the Industry

We provide deeply realistic offensive security services focused on real-world threat emulation.
Our engagements don’t just find weaknesses; they demonstrate how adversaries exploit them, end to end.

Prevent exposure of your valuable assets by posing as real attackers targeting your company.

Review your solution design before, during, or even after implementation.

Uncover vulnerabilities in your network infrastructure. Have you properly segmented and protected your business?

Impersonate employees or vendors to simulate a malicious incident. Threats don't always just come from outside.

Test the security of your implementation that processes personal information, health data, credit card data, media assets, etc.

Trusted by critical infrastructure, finance, and tech companies

Serious Penetration Testing



Dien8 offers a full range of offensive security services, including black-box, gray-box and white-box security audits of applications/services/software, as well as penetration testing and network/wifi/infrastructure vulnerability assessments.

Real targeted attacks

We use a mix of two main approaches while testing your systems and applications: black box testing (usually in the first part), followed by a grey/white box phase. In both cases, the audit process is essentially manual, so it outperforms any existing automated solution in terms of quality of results.

Mobile Security

Breaking mobile applications using a manual approach. Test how your applications communicate with the server infrastructure and whether they behave properly on user devices. We have extensive experience with different platforms and device environments.

Network & WiFi

Our network and wireless penetration tests simulate an attacker's attempt to break into your network infrastructure and gain access to your databases, financial data, customer information, and other sensitive areas.

Client-side Attacks

Identifying weak spots of your internal network by targeting your employees and their mobile/workstations, before they turn into an entry point for malicious actors.
