EresusSecurity

Separate internet-facing risk from scanner noise.

Eresus turns domain, subdomain, cloud asset, exposed service, takeover, leaked secret, and perimeter drift signals into validated attack paths through expert validation.

Vulnerabilities our researchers found and disclosed

Public advisories credited to the Eresus research team. The same people run your engagement.

All advisories

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

Domain and subdomain discovery
Cloud and exposed service mapping
Takeover and misconfiguration validation
Leaked secret and shadow asset triage

Risk signals

Forgotten admin panels
Subdomain takeover
Public buckets and exposed data
Internet-facing staging and debug services

Outcomes

Validated exposure list
Prioritized exploitability
Asset owner mapping
Closure and retest workflow

Evidence standard

Proof you can inspect. Boundaries you can plan around.

Every engagement is bounded by written authorization, evidence handling, and a clear handoff. These are the defaults; the signed scope can tighten them.

Evidence you receive

  • Written scope, authorization, and rules of engagement before testing starts.
  • Reproducible evidence for each validated finding, with sensitive data redacted.
  • Business impact, the affected boundary, and developer-ready remediation direction.
  • Retest status for critical fixes; unresolved items remain visible.

Explicit exclusions

  • Compliance certification or an audit opinion.
  • Unscoped production denial-of-service, destructive actions, or data exfiltration.
  • Full source review unless it is explicitly included in scope.
  • A guarantee that no vulnerability remains after remediation.

Not scanner output. Offensive work that produces proof.

01

Scope and objective

We align assets, workflows, user roles, testing windows, and safe operating boundaries before execution starts.

02

Expert validation

Eresus analysts validate exploitability and business impact instead of forwarding automated scanner output.

03

Proof, fix, retest

Each finding ships with evidence, impact, remediation guidance, and retest steps so teams can close risk quickly.

The questions buyers want answered early.

How do you scope this engagement?+
We start from assets, business workflows, authorization boundaries, and the attack paths that could create material risk. Scope is shaped around exploitability, not checklist volume.
What do we receive at the end?+
You receive proof-backed findings, business impact framing, developer-ready remediation guidance, and a retest path for closure.
Do you help with remediation and retest?+
Yes. We work through remediation direction and validate critical fixes so the team can close risk without guesswork.

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.

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.
