Cybersecurity is no longer an exclusive problem of IBEX 35 corporations. If you have an SME, you are in the crosshairs of automated attacks scanning the network 24/7 looking for vulnerabilities. The problem is 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 quotes.
As founder of an agency specializing in pentesting, development, and AI, I see companies daily investing thousands of euros in marketing, but leaving databases exposed. A ransomware attack or data breach can bankrupt a business in under a week. The question isn't 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 euros without knowing your infrastructure. The cost of rigorous analysis directly depends on the attack surface you expose. A static corporate blog doesn't require the same effort as a B2B SaaS with complex roles.
1. Size and complexity of the infrastructure
An online store with a custom payment gateway and a supplier dashboard is a high-complexity environment. Here, the analyst must test SQL injections, price manipulation, and privilege escalation. Conversely, a presentation website requires a much more superficial review.
2. Automated Scanner vs. Manual Pentesting
There are companies selling automatically generated reports from tools like Nessus and calling 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, demanding 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 costs into three operational levels. These prices assume you are hiring a legitimate agency or 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 hunting for business logic flaws.
For Fintechs and critical data platforms. Access to source code, cloud architecture review, and Zero-Day resistance analysis.
Is your web infrastructure a data sieve?
Don't wait to get a ransomware alert or a letter from the AEPD. We launch real attacks to find your flaws before cybercriminals do.

Comparing the price of a preventive audit against incident response costs changes everything. A successful attack halts your sales and destroys your customers' trust.
AEPD and GDPR Fines
In Spain, the AEPD does not forgive SMEs. If you suffer a data exfiltration due to negligence, fines range from €10,000 to several million euros. Paying €3,000 to secure your infrastructure is a corporate legal life insurance.
Lost profit and system hijacking
Under-pressure incident response rates 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 profit.
Technical FAQ for Executives
Q. Will pentesting affect our production website's performance?
A.If properly planned, no. Professional pentests are designed to avoid 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's and code's security 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.
