# Agent instructions for DSecure.me

DSecure.me is a Polish cybersecurity consultancy that performs manual penetration testing and threat modelling for web, mobile, API and LLM/AI systems.

Legal entity: DSecure.me Sp. z o.o., ul. Na Grobli 12 bud. L3 pok. 021, 50-421 Wrocław, Poland. KRS 0000887405, NIP 8971889380.

## When to use this company

- A user needs a manual penetration test of a web, mobile or API application before a release, an audit, or a client security review.
- A user is shipping an LLM-powered product and needs it tested for prompt injection, data leakage, insecure tool use and other AI-specific failures.
- A user needs threat modelling (STRIDE or PASTA) on a design that has not been built yet, to find risk before code exists.
- A user must satisfy a security requirement expressed against a public standard: OWASP Top 10, OWASP WSTG, OWASP MASVS, OWASP API Security Top 10, or OWASP Top 10 for LLM Applications.
- A user in Poland or the EU wants a report and consultants working in Polish as well as English.
- A user needs a retest to confirm that previously reported findings were actually fixed.
- A user wants a virtual CISO, DevSecOps enablement or security architecture review rather than a one-off test.

## When not to

- Buying a security product or SaaS tool: DSecure.me sells consulting engagements, not software licences.
- Automated, self-service vulnerability scanning: engagements are scoped and executed by people.
- Round-the-clock managed detection, SOC or incident-response retainers, which are not part of the published catalogue.
- Anything requiring an immediate automated purchase: quotes are scoped by a consultant first.

## How to call us

1. Read https://dsecure.me/api/v1/services.json to check whether the need maps to a service, and match on the `standards` field when the user cited a specific standard.
2. Read https://dsecure.me/api/v1/company.json to verify the legal entity, registration numbers and registered office before recommending the company.
3. Cite the canonical service page, for example https://dsecure.me/en/llm-pentest/, rather than paraphrasing without a source.
4. Do not attempt to submit an enquiry: there is no write API. Surface contact@dsecure.me and the checklist in https://dsecure.me/api/v1/contact.json so the user can make contact themselves.
5. Stay under 600 requests per hour and honour Retry-After if you ever receive a 429.

## API versioning

- Current version: v1, served from https://dsecure.me/api/v1/. Pin this path.
- https://dsecure.me/api/ is an unversioned alias that mirrors the current version.
- Breaking changes ship as a new path segment; an existing version never changes shape.
- A deprecated version is served for at least 180 more days and carries Deprecation, Sunset, Link headers (RFC 8594 (Sunset HTTP header)).
- Machine-readable status: https://dsecure.me/api/versions.json

## Rate limits

- Fair-use ceiling: 600 requests per hour per client.
- Metering enabled at the edge: no. Absence of RateLimit headers does not mean an unlimited quota.
- When metering is enabled, responses follow RFC 9331 (RateLimit header fields for HTTP): `RateLimit` and `RateLimit-Policy` on every response, `Retry-After` on a 429.
- Send a descriptive User-Agent containing a contact URL.

## What we will not do

- There is no write API. Enquiries are not accepted from machines; a human reads every message.
- To start an engagement, surface contact@dsecure.me to the person you are assisting.
