ENS Implementation: How to Comply with the Spanish National Security Scheme
1. Introduction ENS implementation (Spanish National Security Scheme, Esquema Nacional de Seguridad) is the process by which a public-sector entity, or a company providing services to it, adapts its information systems to the requirements of Royal Decree 311/2022. ENS implementation is not an administrative formality: it is a risk management programme that affects people, processes and technology, and that requires a prior risk analysis performed with methodologies such as Magerit. In this guide we walk through the phases of ENS implementation, from system categorization to the conformity audit, with real examples of the statement of applicability and an indicative timeline. …
IT Security Audit: What It Includes and How It Is Performed
1. Introduction An IT security audit is the systematic process by which an organization evaluates the real state of its systems, networks, processes and people against cybersecurity risks. For a business owner or a CTO, an IT security audit is not an optional expense: it is the snapshot that allows you to justify investments, detect weaknesses before an attacker exploits them and demonstrate compliance to customers and regulators. In this guide we explain what an IT security audit includes, how it is performed step by step, what deliverables it should produce and how much it costs. We will also look …
Pentesting Service for Businesses: What It Is, Cost and How to Hire It
1. Introduction Hiring a pentesting service for businesses is one of the best-paid security decisions an organization can make: for a bounded cost, it gets a real picture of its vulnerabilities before an attacker does. But the market is full of very different offers, and the difference between a serious pentest and a window-dressing one is not always obvious to the buyer. This article explains what it must include, what it really costs and how to hire it without surprises. The first thing to clarify is what a pentesting service for businesses is not: it is not installing a vulnerability …
Cybersecurity Incident: 7-Step Response Guide for Your Business
1. Introduction A cybersecurity incident response is not a question of “if it happens”, but “when it happens”. The statistics are stubborn: most companies that suffer a relevant attack do not detect it through their own means, but through a third party: a client who warns them, an insurer who calls or the police showing up at the door. The time between compromise and detection, the so-called dwell time, turns every cybersecurity incident response handled too late into a much bigger invoice. That is why the right question is not how to avoid every cybersecurity incident, but how to build …
Cybersecurity for Businesses: 10 Essential Services Every SME Should Have
1. Introduction Cybersecurity for businesses is no longer an optional expense; it is an operational requirement. Every week we learn about an SME losing weeks of revenue because ransomware encrypted its file server, or because a phishing attack with compromised credentials ended in a fraud worth thousands of euros. The data is sobering: according to industry reports, the average cost of a serious incident for a small company exceeds 40,000 euros once downtime, restoration and reputational damage are counted. Cybersecurity for businesses is not only technology: it is a management decision with clear priorities, budget and owners. The usual problem …
How to Become an Ethical Hacker: Complete Career Guide 2026
1. Introduction Knowing how to become an Ethical Hacker is one of the most repeated questions from people who want to enter offensive cybersecurity. And it is no coincidence: the demand for pentesting and security audit professionals far exceeds supply, and salaries in 2026 keep rising. But becoming an Ethical Hacker is not a two-week course: it is a structured path combining technical foundations, intensive practice, recognized certifications and a demonstrable ethical mindset. The most common mistake is starting with the tool: installing Kali Linux, opening Metasploit and “hacking” something without understanding the underlying network, the operating system or the …
Risk Analysis with Magerit: Methodology Applied to a Real Case
1. Introduction Risk analysis with Magerit is the reference methodology in Spain for assessing and treating risks to information systems. Developed by the former Ministry of Public Administrations and maintained by CCN-CERT, Magerit allows any organization, public or private, to identify its assets, understand the threats against them and calculate impact in an objective, reproducible way. In this article we apply the methodology to the real case of an SME with cloud services. Risk analysis with Magerit is not just a practical obligation to comply with the ENS (National Security Scheme) or regulations such as GDPR: it is a management …
OT and ICS Security: Protecting the Industrial World
1. Introduction OT and ICS security has become one of the strategic priorities of industrial cybersecurity. While confidentiality dominates the CIA triad in IT, availability and integrity are absolute in OT environments: a failing PLC can stop a production line, cut the power supply or compromise people’s physical safety. In this article we explore how to protect these critical systems with a practical methodology based on standards such as IEC 62443. The IT/OT convergence, driven by Industry 4.0, has exposed industrial plants to the same threats as corporate networks: ransomware, APTs and insecure remote access. OT and ICS security is …
Threat Intelligence with MITRE ATT&CK: Prioritize and Defend Better
1. Introduction Threat intelligence with MITRE ATT&CK has become the favorite combination of defense teams that want to stop chasing alerts at random. Threat intelligence provides the data (indicators, campaigns, adversary tactics) and MITRE ATT&CK provides the common language to structure it. Working with threat intelligence with MITRE ATT&CK means applying real information about adversaries to a reference framework that every security professional understands, from the SOC analyst to the security architect. In this article you will see the complete workflow: how to collect intelligence through STIX and TAXII, how to map techniques against the MITRE ATT&CK framework, how to …
