Best fit

This engagement creates value fastest for teams like these.

Teams shipping under delivery pressure

Engineering organizations that need backend, mobile, DevOps, or DevSecOps support without losing security rigor.

CTOs and platform leads

Leads that need architecture, release, and operations support tied back to offensive validation priorities.

Programs that want build plus hardening

Buyers that do not want a separate delivery vendor and a separate security vendor working against each other.

Scope

Backend, API, SaaS, and mobile product delivery

Threat modeling and secure architecture decisions

Secure code review and critical-flow validation

CI/CD, secret, and release-gate controls

Risk signals

Authorization and tenant-boundary failures

Unsafe API or session architecture

Secret and dependency-driven supply-chain risk

Security debt hardens as the product grows

Outcomes

Secure delivery roadmap

Architecture and code-review outputs

DevSecOps control checklist

Pre-release security validation

Engagement model

Not scanner output. Offensive work that produces proof.

Scope and objective

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

Expert validation

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

Proof, fix, retest

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

FAQ

The questions buyers want answered early.

How does Delivery Security integrate with offensive pentesting?+

Offensive validation identifies exploit paths; delivery security engineers embed directly alongside your team to implement architecture hardening, secure CI/CD pipelines, and infrastructure as code fixes.

Can you work within our existing agile sprint and release workflows?+

Yes. Our senior engineers operate inside your GitHub/GitLab repositories, Jira/Linear backlogs, and cloud environments, submitting secure pull requests and resolving security blockers without stalling product velocity.

What deliverables and handoff documentation do you provide?+

You receive production-ready code PRs, automated security linting/testing pipelines, infrastructure hardening templates (Terraform/Kubernetes), and comprehensive architecture runbooks for your internal engineering team.

What are the engagement options and timelines?+

We offer sprint-based embedded engineering (2-8 week focused security implementation sprints) as well as fractional DevSecOps & Security Architecture advisory retainers.

How do you ensure secrets and infrastructure credentials remain secure?+

We work exclusively through client-managed least-privilege IAM roles, temporary ephemeral credentials, and encrypted communications under strict mutual NDA and security SLA agreements.

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.

Research

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.
