Penetration Testing

Real attackers don't wait for your next audit cycle. Our penetration testing puts your systems under the same pressure they face in the wild, so you find the vulnerabilities before someone else does.

Web Applications

Our web application penetration testing goes beyond automated scanning. From injection flaws and broken authentication to insecure direct object references, cross-site scripting, and weak session management, we test the full attack surface of your application the way a real attacker would.

Network Testing

Internal and external network penetration testing uncovers what's hiding in your infrastructure. Misconfigurations, rogue services, weak credentials, unpatched systems, and lateral movement paths are all tested against real-world attack scenarios.

Web3 and Blockchain

Blockchain applications operate differently, and the attack surface reflects that. We test smart contract interactions, wallet integrations, RPC endpoints, bridge infrastructure, and frontend injection vectors, bringing the same adversarial mindset to decentralised systems that we apply across all our engagements.

Built on real experiences

Our testing methodology is grounded in OWASP, PTES, and NIST frameworks, refined through hundreds of real engagements. We don't run playbooks. We test the way attackers actually operate.

Experienced team

HYDN's team brings over 35 years of combined cybersecurity expertise. Our testers hold CISSP, CCNP, and GCIA certifications and have worked across financial services, critical infrastructure, and Web3 protocols.

Web3 specialization

Where your stack includes blockchain, DeFi, or decentralised infrastructure, we bring specialist knowledge that general-purpose firms don't carry. Our team understands the protocols, the economics, and the attack patterns specific to this environment.
