Scope
What a properly designed pentest in Madrid should cover
The search intent behind “pentesting Madrid” is usually commercial and operational. Buyers are not looking for theory. They are looking for a provider able to execute meaningful testing, validate real exposure and deliver output that is useful for engineers, security managers, leadership teams and auditors.
APIs and backend services
Security testing of REST APIs and exposed services to identify broken authentication, broken authorization, excessive data exposure, rate-limiting weaknesses, enumeration and endpoint abuse.
Internal network and Active Directory
Controlled simulation of privilege escalation, lateral movement, segmentation weaknesses, insecure trust relationships, credential exposure and paths to critical assets.
External perimeter and exposed infrastructure
Testing of domains, subdomains, public services, remote access, VPNs, perimeter controls and attack surface exposed to the Internet.
This kind of engagement is also valuable for third-party assurance, pre-production validation, security improvement initiatives, audit preparation and technical evidence gathering for frameworks such as ISO 27001, ENS, NIS2 or DORA.

Methodology
How we run a pentesting engagement
Scoping and rules of engagement
Assets, windows, testing mode, exclusions, escalation paths, contacts and business objectives are defined before execution begins.
Reconnaissance and technical analysis
Technology fingerprinting, exposure mapping, discovery, initial control review and attack-path selection based on the agreed scope.
Controlled exploitation
Manual validation and exploitation of weaknesses to measure real impact, access, lateral movement opportunities, data exposure or privilege escalation risk.
Reporting, remediation and retest
Prioritized findings, evidence, practical recommendations and optional retesting once remediation has been implemented.
Important: a good pentest is not about “producing a PDF”. What matters is measuring real impact, translating that into priority, supporting remediation and verifying whether the exposure has genuinely been reduced.
When it makes sense
Typical business scenarios
- Before an audit, assessment or third-party review
- Before launching a critical web platform or API
- After major infrastructure, network or M365 changes
- When leadership needs to understand real exposure
- When technical evidence is needed for ISO 27001, ENS, NIS2 or DORA-related initiatives

FAQ
Frequently asked questions about pentesting in Madrid
What does a pentesting service in Madrid typically include?
It usually includes scoping, rules of engagement, technical testing against the agreed assets, manual validation, a technical report with evidence, an executive summary and, where needed, a retest phase after remediation.
What is the difference between pentesting and a technical security audit?
A technical audit reviews posture, configuration and security controls. Pentesting goes further by attempting controlled exploitation to measure real impact and practical risk. In many cases, both are complementary.
Do you cover web, API and internal network pentesting?
Yes. Hard2bit can cover web applications, APIs, internal networks, perimeter testing, Active Directory, Microsoft 365 and other corporate scenarios depending on the agreed scope.
Do you only deliver a report, or do you also help with remediation?
In addition to the report, we can help prioritize corrective actions, support remediation and retest the fixes so the project reduces real risk rather than just producing documentation.
Do you only work in Madrid?
No. We operate in Madrid and across Spain, and we also work with organizations that have national or international operations. This page is localized for Madrid search intent, but the service is not limited to Madrid.
Can pentesting support ISO 27001, ENS, NIS2 or DORA initiatives?
Yes. A well-scoped pentest can provide valuable technical evidence for security improvement, third-party assurance, audit readiness and broader control validation in frameworks such as ISO 27001, ENS, NIS2 or DORA.
