Combine source code, runtime application, and manual testing into one risk decision.
Eresus combines code, running application, API, identity, business logic, secret, and release-pipeline signals to turn application security testing from scanner output into a proof-driven program.
This engagement creates value fastest for teams like these.
Security and engineering leadership
Teams that need exploit-backed proof before they reprioritize application, API, cloud, or identity work.
Product teams with customer-facing risk
Organizations shipping auth-heavy, multi-tenant, regulated, or internet-exposed systems where logic and authorization flaws matter.
Buyers who need proof, not alert volume
Programs that want reproducible findings, remediation direction, and a closure path instead of scanner noise.
Scope
Risk signals
Outcomes
Turn application security from a tool list into a decision system.
Problem
We identify which app, API, repository, and release flow carry material risk.
Attack scenario
We combine code signals, runtime surfaces, and business logic abuse in one attack path.
Proof
Findings are validated with exploit steps, HTTP requests, code traces, secret evidence, or CI output.
Delivery
Source code analysis, runtime testing, manual validation, and DevSecOps gates become one prioritized program.
The questions buyers want answered early.
How do you scope this engagement?+
How are pricing and engagement models structured?+
What is the typical test duration and delivery timeline?+
What deliverables and report formats do we receive?+
Is retesting included to verify our security fixes?+
Do your reports satisfy DORA, NIS2, SOC 2, and KVKK requirements?+
We tie risk to business impact.
Findings do not stop at severity labels. We explain which customer workflow, data class, or operational objective is affected.
Deliverables work for engineers and executives.
Engineering teams get reproducible proof and remediation direction; leadership gets the risk narrative, priority, and closure status.

Critical Authentication Bypass via JWT Signature Verification Disabled in yargi-mcp
yargi-mcp decodes Clerk JWT tokens with signature verification disabled, enabling authentication bypass, forged identities, and arbitrary scope escalation.
Let’s scope this work against the surface that matters most.
Whether this starts as a pilot, a single application, a critical API, an AI agent flow, or a wider program, we start from the highest-impact surface.
