Web2 and Web3 under one roof
From app pentesting to protocol assessments
Scope to retest, every engagement
How we work
Our workflow stays consistent across every engagement, from web applications to blockchain protocols.
Scope & Threat Model
Define assets, trust boundaries, and the threat actors most relevant to your stack.
Recon & Mapping
Enumerate the real attack surface: endpoints, contracts, infrastructure, and dependencies.
Manual Exploitation
Human-led testing against the logic and trust assumptions automated scanners can't reach.
Severity Triage
Every finding classified by real-world impact and exploitability, not just CVSS defaults.
Reporting & Remediation
Clear writeups with reproduction steps and concrete fixes your team can act on immediately.
Retest & Verify
We confirm every fix actually closes the gap before the engagement is called done.
How we triage findings
Every finding is classified against a fixed severity scale based on real-world exploitability and impact, not a raw CVSS score.
