Security testing is not a checkbox exercise. It's an adversarial simulation.
Every engagement is led by our 30+ senior offensive engineers. We utilize Pair Hacking - the synergy of elite human strategy and proprietary offensive agents - to identify deep-tier flaws that generic scanners miss.
We test complete exploit chains - not isolated vulnerabilities. From client manipulation to backend privilege escalation and data exfiltration, we validate how systems fail under adversarial pressure.
We secure live multiplayer games, fintech platforms, mission-critical SaaS, and blockchain infrastructure operating at scale. High-concurrency environments introduce unique security risks; we test for the edge cases others miss.
Our internal tools, including Cyrex Protoceptor™, enable deep network traffic inspection across custom stacks, engines, and complex protocol layers.
This is security testing designed for production environments - not staging-only validation.
Standard security tools miss deep-tier exploit chains. We built the technology to find them.
Proprietary Network & Protocol Analysis
Engineered by Cyrex to provide deep-tier visibility into network traffic, custom TCP/UDP protocols, and complex multiplayer infrastructure.
This enables deeper validation during:
It enhances manual testing - it does not replace it.

We provide structured, manual security testing across multiple environments.
Security testing should align with risk exposure - not arbitrary timelines.
Security is most effective before users test your system for you.

Cyrex delivers security testing across high-risk, high-scale industries.
Each industry presents distinct threat models. Our testing reflects that.
Cyrex has delivered structured security testing across AAA gaming, enterprise SaaS, and blockchain ecosystems.

Clear structure. No ambiguity.
We define the attack surface, privilege boundaries, and data flow to identify critical business logic risks before testing begins.
Active security testing using our Pair Hacking methodology. We simulate adversarial exploit chains across application, network, and protocol layers.
You receive a detailed technical report with reproducible steps, CVSS-aligned severity scoring, and actionable remediation guidance.
We re-evaluate your environment to verify fixes, ensuring all identified vulnerabilities are fully mitigated before project closure.
Exploits discovered post-launch are exponentially more expensive to remediate. Partner with our offensive security engineers to harden your environment using Pair Hacking.
