Defensive Cybersecurity for Businesses
We harden every layer of your company before the attack arrives.
Defensive cybersecurity brings together all the measures that prevent, detect and contain threats before they cause harm. At GRUPO LINKA we harden every layer of your company, workstation, network, email, identity and data, with defense in depth and Zero Trust, in Madrid and across Spain, so no threat finds a way in.
The Attack Is Not a Question of If, but of When
Threats are automated and no longer care about the size of your company. Preventing costs a fraction of what it costs to recover from an incident.
Rising Threats
Ransomware, phishing and zero-day exploits strike daily, SMEs included, with automated, AI-powered campaigns.
NIS2 Is Now Mandatory
La directiva europea NIS2 requires security measures and incident notification, with penalties of up to €10M or 2% of global turnover.
The Cost of Doing Nothing
A breach means business downtime, data leaks, reputational damage and possible fines. Recovery far exceeds the cost of prevention.
Never Trust, Always Verify
We apply the Zero Trust model: every access is validated, identity, MFA, device posture and policy, before reaching the resource. We minimize the attack surface and stop the attacker’s lateral movement.
Defensive Cybersecurity Solutions, Integrated
From the workstation to data and identity. These are the solutions we use to harden your company end to end.
Endpoint Security (EDR / XDR)
Protection, detection and response on workstations, servers and mobiles. Automatic attack containment and classification of 100% of processes.
Email Protection
Email is the #1 entry vector. Anti-phishing, anti-spoofing, attachment sandboxing and advanced threat filtering.
Perimeter Firewall (NGFW)
Next-generation firewall with deep inspection, IPS, application control and traffic segmentation.
SASE / SSE Solutions
Converged security and networking in the cloud: SWG, CASB, ZTNA and FWaaS to protect the user wherever they are.
Immutable Backup and Recovery
Immutable backup and recovery plans (DRaaS) to restore your business in hours after ransomware or a disaster. Your last line of defense.
Data Protection (DLP + IRM)
Prevents data leaks and protects the document wherever it travels: classification and blocking via email, web, USB or cloud, and persistent encryption that controls who opens, edits or forwards it.
Data Security Posture (DSPM)
Discovers, classifies and monitors where your sensitive data is and fixes exposures before they become an incident.
Identity Management (IAM / PAM)
MFA, least privilege, privileged access control (PAM) and digital certificates to stop the attacker’s lateral movement.
Network Access Control (NAC)
Controls which devices enter your network: profiling, authentication and automatic quarantine of untrusted devices.
Vulnerability & Attack Surface Management
Continuous discovery of exposed assets, vulnerability prioritization and patch management to close doors before they are exploited.
Managed Detection and Response (MDR)
Nuestro Spartan SOC monitors, detects and responds 24x7 as part of managed cybersecurity, with threat hunting and incident response in minutes, not days.
Awareness & Anti-Phishing
Continuous training and phishing simulations to turn your team, the #1 vector, into your first line of defense.
We Reduce Your Attack Surface to the Essentials
Every open port, every excess permission and every unpatched device is a door for the attacker. We apply the principle of minimum exposure and Zero Trust: only what is needed, only for those who need it and only when they need it.
From Incident to Containment in Minutes, not Days
Prevention is not always enough: when something slips through, what matters is how long it takes you to detect and contain it. Our Endpoint technologies (EDR/XDR) respond automatically and our Spartan SOC monitors 24x7 to stop the attack before it spreads.
From Audit to 24x7 Operation
Assessment & Diagnosis
We audit your exposure surface, identities, data, email and endpoints, to know your real risk level.
Strategy Design
We define the layered defense plan and the roadmap based on the criticality of your data and your budget.
Deployment & Configuration
We deploy and fine-tune each control, endpoint, email, network, data and identity, perfectly integrated with one another.
24x7 Operation & Improvement
We monitor, respond and evolve your defense continuously from our Spartan SOC.
From Exposure to Hardening
Each layer filters part of the risk: the perimeter and email stop the entry, the network and Endpoint halt what slips through, identity and Zero Trust cut the attacker’s movement, and data with its immutable backups guarantee that, whatever happens, your business keeps running. The result is a minimum residual risk, measurable and under control.
from detection to containment, with automatic response on the Endpoint and monitoring by Spartan SOC 24/7.
Your Defensive Cybersecurity Ally, from Start to Finish

A Single Point of Contact
From design to operation, a single responsible team. No finger-pointing between vendors or suppliers.
Our Own Certified Engineers
Our own team with certifications from the main vendors. Real, not subcontracted, expertise.
Our Own CyberSOC 24x7
Our Spartan SOC monitors and responds continuously, including out of hours, 365 days a year.
Independent Approach
We choose the technology that fits you best. We are a Tier-1 Partner of the market leaders, not just one.
We Answer Your Questions
What is defensive cybersecurity?+
It’s the set of measures and technologies that prevent, detect and contain threats before they cause harm: endpoint protection (EDR/XDR), email, network, identity and data, under defense in depth and Zero Trust.
How does defensive cybersecurity differ from offensive?+
Defensive protects and contains (prevention, EDR/XDR, Zero Trust). Offensive cybersecurity attacks in a controlled way to find flaws before a real attacker does (pentesting, red team). They complement each other.
Do I have to replace my current security tools?+
No. We start from what you already have, identify the real gaps and reinforce each layer with the leading technology that is missing. The goal is coordinated defense, not starting from scratch.
How quickly is my company protected?+
The first measures (endpoint, email, access) are usually operational within a few weeks. We prioritize what reduces your risk most from day one.
Does this help me comply with NIS2 or the ENS?+
Yes. Well-documented layered defense is the basis for complying with NIS2, ENS and ISO 27001. We align controls with the regulations that apply to you.
What if I have already suffered an incident?+
We help you contain, recover and, above all, close the door they came in through so it doesn’t happen again, with a clear improvement plan.
