DDoS Protection for Businesses: From the 5.6 Tbps Record to Your Downed Site
1. Introduction DDoS protection for businesses is usually treated as a “bandwidth problem”, and that simplification is why so many websites go down every year. A distributed denial-of-service attack is not a network problem: it is a design, provider and response problem. Meanwhile, the numbers keep growing: Cloudflare mitigated 21.3 million DDoS attacks in 2024, 53% more than the previous year, and the historic record was set on Halloween 2024 with 5.6 Tbps generated by around 13,000 Mirai IoT devices. In this article we cover DDoS protection for businesses from start to finish following the denial-of-service chapter of the author’s …
Brute Force and Dictionary Attacks: How to Protect RDP, SSH and Panels
1. Introduction Brute force attack protection is rarely the first thing that comes to mind when a company thinks about its cybersecurity budget, and that is exactly the problem. In 2026, brute force remains the first door attackers try before spending a single hour on exploits or malware. It does not trigger red lights in most companies because failed attempts are archived in the SIEM as background noise that nobody reads. But one successful guess is all it takes for that noise to become access with legitimate credentials. The paradox is that brute force attack protection is also one of …
Insider Threats in Your Company: 7 Signs and How to Respond Legally
1. Introduction Insider threat in business refers to any risk born from a person with legitimate access, current or past, to systems, data or facilities: active employees, former employees with unrevoked access, interns, contractors, consultants, suppliers and partners with connections. While most organizations invest in defending against external attackers, more than half of significant data leaks involve an insider. The data confirms it: according to the Ponemon Cost of Insider Risks 2025 report, covering more than 1,400 organizations, the average cost per insider incident is $17.4 million, and the average time to contain is 81 days. According to Gartner, more …
Selling to the Spanish public sector: the security requirements you must meet
ENS conformity, GDPR with Spanish specifics, data location, certifications, NIS2 flow-down and incident notification: what Spanish public tenders actually require from foreign suppliers. …
DLP Plan for Businesses: Prevent Data Loss (Even from Human Error)
1. Introduction A DLP plan for businesses (data loss prevention) is the organized answer to an uncomfortable question: what sensitive data does your company have, who can access it, and through which channels could it leave without anyone noticing? Most data leaks are not carried out by sophisticated hackers but by human error: a misdirected attachment, an accidental public link or a copy to a personal USB drive to “work better from home”. A well-built DLP plan combines three elements: technology, processes and a governance framework. Technology without the program that sustains it ends up expensive and unused; the program …
Cybersecurity Maturity: From Tier 1 to Tier 4 with NIST CSF 2.0
1. Introduction Cybersecurity maturity measures the degree to which your organization has formalized, consistent and improvable capabilities to identify, protect, detect, respond and recover. It is not the same as sophistication: a small business can be mature for its risk profile without a red team, and a multinational with the most expensive tools on the market can be deeply immature if nobody knows who operates them or what their data actually decides. In this article we will explain how to assess your company’s cybersecurity maturity with NIST CSF 2.0, what Tiers 1 to 4 really mean, how to complement the …
Modern Password Policy: Goodbye to 90-Day Changes per NIST
1. Introduction Your company’s password policy probably still forces employees to change passwords every 90 days and to combine uppercase, lowercase, numbers and symbols. Those two rules, ubiquitous in corporate environments, have been discredited by the standard that security teams cite as their reference: NIST SP 800-63B. In this article we explain what the standard says, why arbitrary expiry and superficial complexity protect nothing, and how to build a modern business password policy aligned with the guidelines NIST published from 2017 onward and updated in 2024. The underlying reason is simple: today’s attacker does not “guess” passwords at the keyboard; …
CEO Fraud and BEC: 8 Controls Before You Accept a Transfer
1. Introduction CEO fraud is the best-known form of Business Email Compromise (BEC): an email that appears to come from senior management orders an urgent transfer, and the victim executes it. But BEC is much more than that final click: it is an industrialized fraud that in 2024 exceeded ransomware in direct economic damage, according to FBI IC3 statistics, and it targets mainly the company’s payment process. In this article we explain how it works, why the corporate mailbox is the stage of the fraud and which eight controls your company needs before an employee presses “accept transfer”. The goal …
ENS security categories: BASIC, MEDIUM and HIGH explained
How the five security dimensions determine your ENS category, why one high rating drags the whole system up, and why over-categorising is not the safe option. …
Simulated Phishing for Businesses: The 5 Metrics That Really Matter
1. Introduction Simulated phishing for businesses is the most effective exercise available to measure and improve how your employees actually respond to a malicious email. It consists of sending messages that are practically identical to a real phishing attack, in a controlled and authorized environment, to observe what your workforce does before a real attacker finds out for you. For years, cybersecurity training was limited to annual courses that nobody remembers. A simulated phishing for businesses program changes the paradigm: instead of talking about threats in the abstract, every employee faces a concrete scenario and receives immediate feedback. Results are …
