Cybersecurity audit in Madrid with technical evidence and a real remediation plan
Hard2bit delivers cybersecurity audits in Madrid for organizations that need to measure their real security posture. We review infrastructure, identity, Microsoft 365, cloud, privileged access and technical exposure against frameworks such as ENS, ISO 27001, NIS2 and DORA, producing prioritized findings, defensible audit evidence and a remediation plan teams can actually execute.
We are a Spanish cybersecurity company founded in 2013, headquartered in the Community of Madrid (Leganés and Las Rozas). The security audit service is part of Hard2bit's own certified scope under ENS High category (Royal Decree 311/2022) and ISO/IEC 27001:2022, audited by an ENAC-accredited body. The same team covers technical audits, pentesting, vulnerability management, Microsoft 365 security and compliance work.

Scope
What a properly designed cybersecurity audit in Madrid should cover
The search behind "cybersecurity audit Madrid" usually comes from buyers who want a local provider with real technical judgment and the ability to connect findings to demanding regulatory frameworks — not a generic PDF. This is the coverage we normally deliver.
Compliance audit (ENS, ISO 27001, NIS2, DORA)
Gap analysis against the applicable framework, control mapping, defensible audit evidence and a prioritized remediation plan with clear closure criteria — designed to hold up under external certification or regulatory scrutiny.
Microsoft 365, Azure and cloud audit
Secure configuration review, identity, MFA, conditional access, external exposure, logging and cloud security posture across Microsoft 365, Azure and other cloud platforms commonly used by Madrid-based organizations.
Identity, privileged access and IT processes
Identity lifecycle, privileged accounts, access recertification, joiner/leaver processes and IT/security governance — a recurring weak point in growing companies and a frequent finding in external audits.
The scope adapts to the goal: preparation for ENS or ISO 27001 certification, NIS2 or DORA alignment, a review requested by a client or investor, validation before a major infrastructure change, or recurring assurance after an incident.
Why Hard2bit
What makes us competitive for cybersecurity audit work in Madrid
Madrid-based team
Offices in Leganés and Las Rozas. Onsite kickoff at no extra cost, working sessions at the client's site when it adds value, and real operational proximity for companies based in the Community of Madrid.
Technical audit and compliance under one roof
We are not a paperwork-led consultancy. The same team delivers technical audits, pentesting, vulnerability management, Microsoft 365 security, incident response and compliance work.
Experience across the Madrid business ecosystem
We have worked with public administration, private healthcare, industrial operators along the Henares corridor, retail, financial services, energy and B2B SaaS — sectors with real economic weight in the region.
From audit to remediation to revalidation
The audit does not end with a report. We help prioritize, support the implementation of corrective actions and revalidate the closure of findings when the project calls for it.
Methodology
How we run an audit engagement
Scope and regulatory context
Assets, sites, criticality, applicable framework (ENS, ISO 27001, NIS2, DORA, GDPR), stakeholders, execution windows and quality criteria are defined before work begins.
Evidence gathering and technical review
Interviews, document review, configuration analysis, technical validation, exposure discovery and controlled testing against the assets in scope.
Analysis, prioritization and framework mapping
Findings are mapped to the applicable framework, scored by impact and exploitability, separated into immediate-impact actions and structural debt, and translated into a remediation plan.
Report, remediation plan and revalidation
Technical report with evidence, executive summary for leadership, prioritized remediation plan, hands-on support during remediation and revalidation of closure where applicable.
Important: a good audit is not measured by the thickness of the report. It is measured by the quality of the decisions it enables afterwards — what gets prioritized, what gets closed, what holds up under external scrutiny and what stops being a real risk.
Frameworks and methodologies
Standards and competent bodies that guide our audit work
A solid audit is not invented from scratch — it builds on internationally recognized frameworks and on guidance from competent bodies, both national (CCN-CERT, INCIBE, ENAC) and international (ISO, NIST, OWASP, CIS, ENISA). That is the basis for the plan, the tests and the evidence we produce.
ISO/IEC 27001:2022 and ISO/IEC 27002:2022
Information security management system and international control catalogue. Hard2bit is certified to ISO/IEC 27001:2022.
ISO/IEC 27007 and ISO 19011
International guidelines for auditing information security management systems. Methodological backbone for audit planning, execution and evidence handling.
ENS — Royal Decree 311/2022 and CCN-STIC guidance
Spain's National Security Framework and the Series 800 guidance issued by the Centro Criptológico Nacional (CCN-CERT) — required reading for the public sector and its technology providers.
NIST SP 800-53 and NIST Cybersecurity Framework
Control catalogue and risk management framework from the US National Institute of Standards and Technology — a global reference for audit work and benchmarking.
OWASP ASVS and OWASP Testing Guide
Application Security Verification Standard and Testing Guide maintained by the Open Web Application Security Project — the technical foundation for web and API assessment.
CIS Benchmarks and CIS Controls
Secure configuration guidance and controls from the Center for Internet Security, widely used to assess hardening across operating systems, cloud platforms and services.
ENISA and NIS2 guidance
Guidance from the European Union Agency for Cybersecurity, directly relevant for entities in scope of NIS2 and their compliance audits.
NIST SP 800-115 and PTES
NIST's technical guide to information security testing and the Penetration Testing Execution Standard — references for the technical validation component of the audit.
Framework selection is matched to the goal: ENS and CCN-STIC for systems in the Spanish public-sector scope; ISO/IEC 27001 for corporate certification; the NIST CSF as a common international language; OWASP for the web/API layer; CIS for platform hardening; ENISA for NIS2.

FAQ
Frequently asked questions about cybersecurity audit in Madrid
What does a cybersecurity audit in Madrid typically cover?
A cybersecurity audit in Madrid usually includes scoping, a technical review of infrastructure, identity, Microsoft 365, cloud and processes, a gap analysis against the applicable framework (ENS, ISO 27001, NIS2, DORA or GDPR), a technical report with evidence, an executive summary for leadership and a prioritized remediation plan.
What is the difference between an audit and a pentest?
An audit reviews posture, configuration, processes and controls against a chosen reference framework. Pentesting goes further by attempting controlled exploitation to measure real impact. In many projects they are complementary: the audit provides breadth, the pentest provides technical depth where it matters most.
How long does a cybersecurity audit take?
It depends on scope. A focused audit on Microsoft 365 or a single system can typically be delivered in two to three weeks. A full ENS or ISO 27001 readiness audit across a mid-sized organization usually takes four to eight weeks, including interviews, technical review and final reporting.
Is the audit useful for ENS, ISO 27001, NIS2 or DORA certification?
Yes. The audit is designed to map findings to the applicable framework, identify gaps against certification or legal obligations, prioritize corrective actions and leave a clear evidence trail. It is the natural step before a certification audit or a sector-specific inspection.
Do you only work with companies in Madrid?
No. We deliver across Spain and support clients with international operations as well. This page is localized for Madrid search intent because much of our work is here, but the service is delivered nationally without travel surcharges within the Community of Madrid.
Do you only deliver a report, or do you also support remediation?
We support remediation. After the report we help prioritize, work with internal teams or third parties to implement corrective measures, validate closure of critical findings and, where it makes sense, confirm a real reduction in exposure with a revalidation phase.
What deliverables does the client receive?
A technical report with findings, evidence and recommendations; an executive summary for leadership and the steering committee; a prioritized remediation plan; a framework mapping matrix where applicable; and, for certification engagements, a complete evidence dossier ready for external audit.
Who actually runs the audit?
Our own in-house team. Auditors with real hands-on experience in infrastructure, identity, cloud and regulation — not subcontracted profiles. Hard2bit's ENS High accreditation and ISO 27001 certification require strict control over the personnel delivering sensitive engagements.
Is Hard2bit's own audit service part of a certified scope?
Yes. The security audit service is part of Hard2bit's own certified scope under ENS High category (Royal Decree 311/2022) and ISO/IEC 27001:2022, audited by an ENAC-accredited body. The service we deliver to clients is itself subject to a recurring external audit against public criteria.
Which methodologies and standards do you use?
Our audit work draws on internationally recognized frameworks: ISO/IEC 27001:2022 and ISO/IEC 27002:2022 for controls, ISO/IEC 27007 and ISO 19011 for audit methodology, NIST SP 800-53 and the NIST CSF as international references, OWASP ASVS and the OWASP Testing Guide for the web and API component, CIS Benchmarks for hardening, CCN-STIC Series 800 for ENS work, and ENISA guidance for NIS2.
