// AGENTS · HARDEN PRODUCT & STACK

Use AI agents to harden your product and your infrastructure

At The Vibe Company, we deploy agents that watch secrets, dependencies, IAM, configs and pull requests — continuously, inside your CI/CD and your infrastructure — to shrink the attack surface before anything reaches production.

What you get
  • A fleet of agents and versioned skills, not a one-shot audit delivered as a PDF.
  • Plugged into your stack (CI, repos, cloud, SaaS) with least privilege.
  • Delivered to GDPR and HDS requirements when the context calls for it.
  • The same YC W24 team that ships AI products to production (Monka, LocService, AFP…).

Classic security tools are no longer enough on their own

The surface to protect has changed: dozens of SaaS tools wired into your data, coding agents opening pull requests, years of accumulated configs and permissions. Each tool sees its own slice; nobody sees the whole.

A one-off audit or a quarterly scan captures a state that drifts the very next day: a role widened “temporarily”, a dependency bumped, a bucket opened for a test. CTOs, CISOs and platform leads need a continuous loop, not one more report.

Recent incidents are a reminder: exposed secrets and legacy runtimes are still open doors. We broke them down in Black October: what it means for AI agents.

What the agent fleet covers

Six workstreams, plugged into the tools you already run. Each agent has a clear scope, minimal permissions and skills versioned like code.

01Repos · CI

Secrets & credentials

Detects keys and tokens in repos, CI, tickets and logs. The agents raise the alert and prepare the rotation; a human approves it.

02Supply chain

Dependencies & supply chain

Tracks CVEs, lockfiles and risky packages, with merge policies enforced right in the CI.

03Cloud · SaaS

IAM & SaaS permissions

Role drift, dormant accounts, overly broad OAuth scopes: the agents spot the gap and propose the way back to least privilege.

04IaC

Configs & infrastructure as code

Drift in security groups, buckets and policies between what your code declares and what actually runs.

05Pull requests

Security PR review

Review skills dedicated to sensitive diffs (authentication, crypto, input validation) that comment on the pull request before it merges.

06Agents · MCP

Agent & MCP perimeter

Before agents plug into your systems: tool allowlists, server-side secret injection, sandboxed execution.

What is an MCP server?

The agents propose and automate behind guardrails. Critical decisions (rotating a production secret, changing permissions, a sensitive merge) stay with humans.

How we roll it out with you

Not a scanner you plug in and forget: a fleet of agents running in your environment, with your tools and your teams.

Six steps
  1. 01Mapping

    Map the surface

    Repos, CI, cloud, critical SaaS and the agents already in place: we start from what actually exists.

  2. 02Prioritizing

    Prioritize by risk and effort

    We start with what exposes the most for the least effort. No endless scanner, no backlog of a thousand alerts.

  3. 03Deploying

    Deploy skills and agents in your environment

    The agents run on your side, with minimal permissions and skills versioned like the rest of your code.

  4. 04Integrating

    Wire in CI/CD and your alert channels

    Findings land in the pull requests, tickets and channels your teams already use.

  5. 05Measuring

    Measure the useful signal

    We track true positives handled, not vanity dashboards.

  6. 06Handover

    Hand over, or operate with you

    Documentation, runbooks and training for your teams. Or we keep running the fleet alongside you.

Why The Vibe Company

  • We already run agents and products in production, for clients with real constraints: the case studies below give the details.
  • We write about it in public: Black October, agent authority (in French), and an upcoming series on hardening products and infrastructure.
  • AI agency in Paris, YC W24. We work to GDPR and HDS requirements.

What this is not

01

Not a replacement for your CISO or a pentest

The agents equip your security team, they do not replace it. A penetration test by a qualified provider remains a separate exercise.

02

Not a compliance promise

We sell no label and no certification. We work to the GDPR and HDS requirements of your context, and document what was done.

03

Not just “securing the prompt”

Securing the agents themselves matters, but here the hardening targets your product and your infrastructure.

Frequently asked questions

How do agents differ from a classic SAST/DAST scanner?

They complement each other. Scanners stay useful in the CI. Agents chain context across several tools (code, tickets, configs, permissions), connect the signals and prepare the fix.

Do you touch production?

With minimal permissions. Every sensitive change is a proposal that a human on your team approves before it is applied.

What about data, health data (HDS) in particular?

We work to GDPR and HDS requirements. When health data is involved, the agents run inside the client's covered environment. We claim no certification we do not hold.

How does this relate to securing the agents themselves?

The two reinforce each other. To secure an agent (authority, secrets, execution), read our Black October article and our article on agent authority. For agents that harden your product and your infrastructure, this is the page.

Where do we start?

With a 30-minute call: your current surface, your CI and your critical SaaS. We will tell you straight whether a fleet of agents makes sense for you.
