Cybersecurity is no longer an exclusive problem for Fortune 500 corporations. If you own an SME, you are in the crosshairs of automated attacks scanning the web 24/7 looking for vulnerabilities. The problem is that most executives assume security is an unaffordable expense. Today I will break down exactly how much a web security audit for SMEs in Spain costs, with no beating around the bush or opaque budgets.
As the founder of an agency specializing in pentesting, web development, and AI, I see companies investing thousands of euros in marketing every day, while leaving their databases exposed. A ransomware attack or data breach can bankrupt a business in less than a week. The question is not how much it costs to protect yourself, but whether you can afford the cost of not doing so.
Why the price is not a fixed number
In the tech sector, distrust anyone offering a "complete audit" for €300 without knowing your infrastructure. The cost of a rigorous analysis depends directly on your exposed attack surface. A static corporate blog does not require the same level of effort as a B2B SaaS with complex user roles.
1. Infrastructure size and complexity
An online store with a custom payment gateway and a supplier dashboard is a highly complex environment. Here, the analyst must test for SQL injections, price manipulation, and privilege escalation. In contrast, a presentation website requires a much more superficial review.
2. Automated Scanner vs. Manual Pentesting
There are companies that sell reports automatically generated by tools like Nessus and call it "pentesting." An automated scan detects known vulnerabilities (CVEs) but is blind to business logic flaws. Real pentesting involves manual tactics and hours from a senior consultant.
3. Tech stack and CMS
Using a commercial CMS like WordPress reduces certain uncertainties. However, if you use custom code in Laravel, React, or Node.js, the auditor starts from scratch, requiring an intensive review of authentication, sessions, and API integrations.
Price ranges in Spain (Updated 2026)
Based on current rates in the Spanish market, I have categorized the costs into three operational tiers. These prices assume you are hiring a legitimate agency or a certified professional.
Ideal for simple corporate websites. Combines automated scanning with light manual validation to catch misconfigurations.
For SaaS and E-commerce. Intensive manual testing (OWASP Top 10), token manipulation, and business logic flaw hunting.
For Fintechs and critical data platforms. Source code access, cloud architecture review, and Zero-Day resistance analysis.
Is your web infrastructure leaking data?
Do not wait for a ransomware alert or a fine from the Data Protection Agency (AEPD). We launch real attacks to find your flaws before cybercriminals do.

Comparing the price of a preventive audit against the cost of incident response changes everything. A successful attack paralyzes your sales and destroys your customers' trust.
AEPD and GDPR Fines
In Spain, the Data Protection Agency (AEPD) does not spare SMEs. If you suffer a data exfiltration due to negligence, fines range from €10,000 to several million. Paying €3,000 to secure your infrastructure is corporate legal life insurance.
Loss of profit and system hijacking
Incident response rates under pressure triple the cost of a planned pentest. Hacked SMEs are typically inactive for an average of 5 to 7 days. Do the math on your weekly lost profits.
Technical FAQ for Executives
Q. Will pentesting affect our production website performance?
A.If planned correctly, no. Professional pentests are designed not to cause Denial of Service (DoS). We always request a pre-production environment that is an exact clone.
Q. We use AWS / Google Cloud, don't they handle security?
A.No. Cloud providers operate under a shared responsibility model. They secure the hardware, but your application security and code are 100% your responsibility.
Q. How long does a security audit take to complete?
A.An intermediate-level pentest for a standard SME usually requires between 1 and 3 weeks. The active attack phase lasts between 3 and 7 business days.
Q. We have an internal development team, can they do the audit?
A.This is a bad practice known as "marking your own homework." Developers have biases about their own code and are rarely up-to-date on offensive exploitation techniques.
