IT Security Audit for Businesses
Discover and fix your vulnerabilities before an attacker does.
Una IT security audit assesses the real state of your protection and detects vulnerabilities before an attacker uses them. We audit your web, your code, your servers, your networks and your whole ecosystem, in Madrid and across Spain, with controlled, risk-free tests, and a report that actually makes sense.
No Risk
Controlled tests, without endangering your operations.
Certified
Auditors with certifications and years of experience.
Preventive
We detect and also fix the vulnerabilities.
Clear Report
Executive and technical, with a prioritized action plan.
Don’t Test Your Vulnerability, Get Ahead of It
43% of cyberattacks target SMEs and most get in through a flaw the company didn’t know about. An IT security audit tells you, with data, the real state of your cybersecurity.
We run a battery of controlled tests, always risk-free for your operations, to determine the state of your infrastructure, detect vulnerabilities, inform you with a complete report and, if you wish, fix them.
From Scope to Action Plan
A clear, measured process, from start to finish, that ends with concrete actions to harden your company.
Audits for Your Whole Ecosystem
Web Audit
We analyze your web and applications to detect injections, XSS, session flaws and every OWASP vulnerability.
Source Code Audit
We review your code for security bugs, backdoors and bad practices before they reach production.
Perimeter Audit
From the outside, we assess your perimeter to discover ports, services and vulnerabilities exposed to the Internet.
Internal Audit
From your local network we simulate an internal attacker to measure the real level of internal security.
Server & Infrastructure Audit
We review hardening, patches, configurations and exposure of servers, hypervisors and critical services.
Mobile Device Audit
We assess the security of BYOD devices and your employees’ corporate mobility.
WiFi Network Audit
We measure the security of your wireless network inside and outside your premises.
SCADA / ICS Audit
We audit industrial control systems and critical infrastructure (OT) with a specific, risk-free methodology.
Red Team Exercise
We simulate a real adversary: our auditors attempt the intrusion to test your detection and response.
Already Been Attacked?
If you have suffered an incident, our computer forensics team collects and analyzes the digital evidence to determine the origin, scope and how the attack happened.
A rigorous analysis, with expert-witness validity, to respond, recover and prevent it happening again.
Does NIS2 Affect You? Start Here
The NIS2 directive and frameworks like ISO 27001, ENS or DORA require you to demonstrate, with evidence, the state of your cybersecurity. An audit is the first step: it tells you where you are and what you’re missing.
We cross the audit findings with the requirements that apply to you and deliver a prioritized compliance plan, ready to face certification or inspection.
We Audit with International Standards
OWASP
The reference methodology for auditing web applications and APIs (OWASP Top 10 and ASVS).
OSSTMM
An open, measurable and repeatable security testing standard for penetration testing.
PTES
Penetration Testing Execution Standard: a complete framework for the professional pentest lifecycle.
MITRE ATT&CK
We map each finding to real attacker tactics and techniques to prioritize by impact.
NIST
NIST frameworks (CSF and SP 800-115) to structure the assessment and risk management.
CIS Benchmarks
We verify system and service hardening against the recognized CIS Benchmarks.
From Scope to Action Plan
We scope it with you, test thoroughly (manual and automated), verify each finding with a proof of concept and deliver a clear, prioritized report, with a re-test after remediation.
We follow recognized methodologies (OWASP, OSSTMM, PTES) and support you until we verify that every risk is closed.
We Answer Your Questions
Can the audit take down or damage my systems?+
No. We work with controlled tests agreed with you, with no risk to the integrity or availability of your operations.
How long does a cybersecurity audit take?+
It depends on the scope (web, code, infrastructure, network…). After an initial meeting we give you a plan with timelines and a fixed quote.
Does it help me comply with NIS2 or ISO 27001?+
Yes. We cross the findings with the requirements that apply to you and deliver a prioritized compliance plan to face the regulation or certification.
What do I get when it’s finished?+
An executive report for management and a technical one for your team, with each vulnerability prioritized by criticality and its remediation recommendation.
Do you only detect or also fix?+
Both. We can stop at the diagnosis or support you in remediation and re-verify that everything is closed.
How often should I be audited?+
At least once a year and after major changes. More and more companies opt for a continuous exposure management approach (CTEM).
