Penetration testing for businesses: find your vulnerabilities before attackers do

A proper penetration test isn't an automated scan. It's an expert who thinks like an attacker, looks for the least expected path and shows you exactly how far someone with bad intentions could get.

Is your company secure, or does it just think it is?

73% of companies that suffer a serious cyberattack thought their systems were up to date. Firewalls, antivirus and patches aren't enough if there are vulnerabilities in your web application, in your internal network configuration or in the way your employees manage credentials. Penetration testing simulates what a real attacker would do: it searches, exploits and shows you the path before someone with bad intentions finds it first.

What type of pentesting do I need?

  • Web pentesting: applications, customer portals, e-commerce, APIs
  • Internal and perimeter network pentesting: exposed IPs, VPNs, firewalls
  • Active Directory pentesting: privilege, GPO and lateral movement audit
  • API pentesting: REST, GraphQL, OAuth/OIDC
  • Mobile application pentesting: iOS and Android
  • Red Team: advanced and persistent attack simulation

How we run a penetration test

  1. Reconnaissance: We gather information about your infrastructure, domains, technologies and possible attack vectors without direct access to your systems.
  2. Enumeration: We identify active services, software versions, entry points and possible exposed credentials.
  3. Controlled exploitation: We attack the vulnerabilities found in a controlled way to confirm their real impact and how far an attacker could get.
  4. Post-exploitation: We assess what can be done once inside: privilege escalation, access to sensitive data, lateral movement.
  5. Report and remediation: We document every finding with evidence, classify it by severity and give concrete instructions to fix it.

What you get when we finish

  • Executive report: risk in business terms, for management and the CISO
  • Technical report: vulnerabilities with PoC, CVSS and step-by-step recommendations
  • Closing meeting to explain the findings to the technical team
  • Availability to answer questions during remediation
  • Optional re-test to verify that critical issues have been fixed

When should you hire a penetration test?

  • Before launching a web or mobile application to production
  • After a merger or acquisition (cybersecurity due diligence)
  • When an enterprise client or external auditor requires it
  • After implementing major infrastructure changes
  • To comply with NIS2, DORA, PCI-DSS or other regulations
  • If it's been more than a year since your last intrusion test

Frequently asked questions about pentesting

How much does a penetration test cost in Spain?

The price depends on the scope: number of IPs, URLs, applications and depth of the analysis. A standard web pentest is usually between 1,500 EUR and 5,000 EUR. More complex projects such as a Red Team or a full infrastructure pentest can exceed that. We always start with a free first call to give you a quote tailored to your reality.

Can pentesting affect the availability of my systems?

We define the scope precisely before starting. By default, we avoid actions that could interrupt the service (DoS, data deletion). If any test carries potential risk, we agree it with you and run it during a maintenance window.

What's the difference between a pentest and a vulnerability assessment?

A vulnerability assessment is an automated scan that detects possible flaws but doesn't verify or exploit them. A pentest goes further: a human expert confirms the vulnerability is exploitable, demonstrates its real impact and assesses whether it allows escalating the attack. The result is far more actionable.

What's the difference between a pentest and ethical hacking?

A penetration test is a technical test scoped to one specific system or surface: a web app, an API, a network. Ethical hacking is a broader assessment that combines multiple vectors — OSINT, external perimeter, internal network, privilege escalation — to simulate a full attack campaign against your organization. If you need to assess a specific system, choose penetration testing; if you want to know how far a real attacker would get across your whole organization, choose ethical hacking.

What information do you need to start?

It depends on the type of test. For a black-box pentest, we only need the URLs or IPs in scope. For grey or white box, we may need test credentials, source code access or architecture documentation. We agree everything before starting.

How long does a pentest take?

Between 3 and 10 business days for the technical phase, depending on the scope. The report is usually delivered 2-3 days later. For Red Team projects or complex infrastructures, the timeline can extend.

How do I hire a penetration test for my company?

The process is simple: you describe your environment (URLs, IPs, applications or internal network in scope), we hold a free initial call to understand your needs, and within 24-48 hours you receive a proposal with scope, methodology and price. No fine print, no charges for the initial analysis.
