Penetration testing in Marbella & Costa del Sol: the complete guide.

A penetration test is a human adversary, hired by you. An operator takes the same access a real attacker would have — the public internet, a phished credential, a foothold on one workstation — and chains real weaknesses into demonstrated access to your systems and data, then documents exactly how, with proof. A vulnerability scan, by contrast, is software producing a list of potential issues, most of which were never exploitable and some of which hide the one path that is. Scans are a hygiene tool; a penetration test is evidence. Auditors, regulators, insurers, and courts treat the two completely differently — and so do attackers. If a quote arrives within minutes, prices like a subscription, or promises “unlimited pentesting,” you are being sold a scan. We wrote more on this in why vulnerability scanners are dying.

External network testing attacks what the internet can see — your perimeter, VPNs, mail, and exposed services. Internal testing assumes one workstation is compromised and measures how far an attacker gets: usually the most sobering report a business ever reads. Web application and API testing targets the software your customers touch, from authentication logic to injection paths. Cloud testing hunts IAM over-privilege, exposed storage, and misconfiguration across M365, AWS, Azure, and GCP. AI & LLM testing red-teams the models and agents you’ve deployed against prompt injection, data leakage, and tool abuse — the OWASP LLM Top 10, proven, not theorized (see securing AI’s new attack surface). Social engineering tests your people — phishing, vishing, pretexting. And red team operations combine all of it into a stealth campaign against your detection and response, not just your prevention.

Honest market ranges — every firm scopes differently, but for a typical SMB engagement in this market you should expect:

Scope drives everything: number of external hosts, internal subnets, applications, and whether social engineering or physical access is in play. Two warnings from inside the industry: a price dramatically below these ranges buys a rebranded scan, and a price quoted without a scoping call buys a template. A real firm asks questions before it quotes.

Spain’s NIS2 transposition — the draft Ley de Coordinación y Gobernanza de la Ciberseguridad — is still in the parliamentary process, which creates a trap: the obligations are arriving anyway, through contracts, as larger clients, insurers, and public bodies impose NIS2-grade security requirements on their suppliers today. Meanwhile the law that already binds everyone is GDPR Art. 32, enforced by the AEPD, which mandates regular testing and evaluation of security measures — and Spanish sanctions for inadequate security are among Europe’s most active. The ENS (Esquema Nacional de Seguridad) binds anyone serving the public sector, and PCI-DSS covers the region’s hospitality and retail payment flows. Testing now, with documentation, is how you satisfy today’s law and be ready the day the NIS2 law lands.

The Costa del Sol’s economy runs on high-value transactions: property closings, yacht and marina services, private clinics, boutique hotels, and the family offices behind them. That makes business email compromise and invoice fraud the region’s signature attack — one spoofed mailbox away from a six-figure wire to the wrong account — alongside ransomware against hospitality operations that can’t afford downtime in season. Down the coast, Málaga’s TechPark corridor is scaling SaaS and services on young infrastructure. On engagements here we most often get in through phished M365 credentials, payment-workflow gaps, and remote access set up for convenience and never reviewed.

Five filters separate operators from resellers. Ask who does the work — names and certifications of the actual testers (look for hands-on-keyboard certs like OSCP, CRTO, CPTS, PNPT, earned by exploitation, not multiple choice). Ask for a sanitized sample report — if it’s a scanner export with a logo, walk. Ask how findings are proven — real firms deliver reproduction steps and proof-of-concept, not CVSS scores copy-pasted from a database. Ask what happens after the report — remediation guidance and a retest to verify fixes should be included, not upsold. And ask about scoping — a firm that quotes without understanding your environment is pricing a template, not your risk. We’re happy to be held to all five: meet the team.

A real deliverable has four layers. An executive summary in plain language your leadership and clients can read — what an attacker could do to the business, not jargon. Technical findings, each with severity, reproduction steps, and proof-of-concept evidence. A prioritized remediation roadmap — what to fix first and why, scoped to your team or MSP. And a retest verifying the fixes actually closed the paths. That document then earns its keep for years: it’s the evidence your auditor requests, the artifact your cyber insurer prices against, the attachment that closes enterprise deals, and — under the legal frameworks above — part of your defense file.

For Costa del Sol SMEs, external penetration tests typically run €5,000–€15,000, internal or web-application engagements €8,000–€25,000, and red team or fraud-simulation exercises from €25,000, depending on scope.

GDPR Art. 32 requires a process for regularly testing, assessing and evaluating the effectiveness of security measures. Penetration testing is the most direct way to produce that evidence — and after a breach, the AEPD asks for exactly this kind of documentation.

No. The draft law’s requirements mirror the EU directive, larger clients are already writing NIS2-grade obligations into contracts, and programs take months to build. Testing and documenting now means the day the law is published, you’re already compliant instead of starting a scramble.

Yes — BEC simulation is one of our most-requested engagements in this region: we test mail security, payment-approval workflows, and staff response to realistic pretexts, then harden the exact path a fraud crew would take.

A scan is an automated list of potential weaknesses. A penetration test is a human operator chaining them into demonstrated access — proof, not possibilities. Regulators and insurers treat the two very differently.
