INFRASTRUCTURE SECURITY
System hardening that reduces your attack surface
We harden servers, containers and endpoints with secure configurations, patching and least privilege, and document every change so the baseline stays verifiable.
System hardening that reduces your attack surface
System hardening matters when you want to harden servers, containers and endpoints with secure configurations, patching and least privilege to reduce the attack surface of your infrastructure. Before running any test, we agree in writing on the scope, limits, assets and success criteria so the result is verifiable and auditable.
We work from Barcelona and Madrid and remotely with teams across Spain, Europe, LATAM and the United States. The process combines scope sessions, verifiable deliverables and documentation of every finding so progress stays visible.
We hand over reports, evidence and configurations in accounts owned by your company and under a confidentiality agreement. You can therefore audit, remediate or change supplier without relying on private access or undocumented results.
We harden servers, containers and endpoints with secure configurations, patching and least privilege, and document every change so the baseline stays verifiable. That is why we prioritise a repeatable, documented process you can audit and reuse for every security review.
THE CHALLENGE
The challenge of systems hardening
default systems leave a wide attack surface
Uninventoried attack surface
Servers accumulate open services and ports nobody reviews, so without an inventory you cannot decide what to harden first.
Default configurations still active
Factory credentials and settings remain in production, leaving known entry vectors that are easy to exploit.
Irregular, unprioritized patching
Teams apply patches without criticality order, so exploitable vulnerabilities stay open longer than necessary.
APPROACH
How we fix reducing the attack surface
We move forward with measurable decisions and releases that already add value.
Audit and baseline
We review systems, services and accounts to establish the real state before changing anything.
Layered hardening
We apply controls by layer — system, network, applications and access — from lowest to highest risk.
Documented rules and exceptions
We define what gets hardened and what is allowed for business reasons, with traceability of each decision.
Continuous verification
We check compliance after every change and leave guidelines to keep the security posture.
DELIVERABLES
What systems hardening leaves ready
We deliver an operational foundation your team can govern and keep improving.
Baseline report
Document with the initial security state and findings ordered by criticality.
Hardened systems
Configuration applied and verified on the agreed machines without breaking business services.
Rules and exceptions catalog
Traceable record of each applied control and each authorized exception with its justification.
Secure maintenance guide
Clear instructions to review and sustain hardening after project closure.
TRUST
Technology applied to real operations
We carry out audits and penetration tests from Barcelona and Madrid, with actionable reports and fully under client control.
- Scope, limits and assumptions agreed in writing before any test begins.
- Findings prioritised by real exploitation risk, with reproducible evidence.
- Verifiable remediation and documented re-testing, without promising zero vulnerabilities.
- Reports, artefacts and configurations delivered under your ownership and confidentiality.
