60% of SMEs That Are Attacked Close Within 6 Months.
Is Yours Protected?
Cybersecurity is no longer optional — it is a matter of business survival. Across Europe, attacks on small and medium-sized businesses have tripled in the past year. Ransomware, phishing, data theft and GDPR breaches can destroy years of work in minutes.
We implement complete protection solutions: security audits, defence against ransomware, GDPR compliance and continuous 24/7 monitoring — tailored to the reality and budget of SMEs.
The 4 Risks That Are Leaving Your Business Vulnerable
Most SMEs have at least 3 of these problems. Each one is an open door for cybercriminals who actively look for easy targets.
Employees Click on Phishing Links
91% of cyberattacks start with a phishing email. It only takes one employee clicking the wrong link to compromise the entire company network — passwords, customer data, financial information. Without adequate training and regular simulations, your team is the weakest link in the security chain. Attackers know this and invest more and more in convincing, personalised emails.
No Functional Backup Strategy
Many businesses only discover that their backups do not work when they need them — after a ransomware attack or hardware failure. Backups on the same server, outdated copies, lack of restore testing or simply non-existent backups are recipes for disaster. When ransomware encrypts everything, without a working backup the only option is to pay the ransom — with no guarantee of recovery.
Outdated Software with Vulnerabilities
Every postponed update is a known vulnerability that attackers can exploit. Unpatched operating systems, obsolete WordPress plugins, router firmware that is never updated, old versions of Office and Adobe — every outdated item represents an entry point that hackers know about, document publicly and exploit with automated tools. It only takes minutes to compromise an unprotected system.
Zero Incident Response Plan
When the attack happens, most SMEs do not know what to do. Without a documented and tested plan, the team panics, critical time is lost in the first hours and damage multiplies exponentially. The difference between recovering in hours or in weeks lies in prior planning. Who to contact, which systems to isolate, how to communicate with customers — everything must be defined before the incident happens.

View full case →Complete Protection. Without Complexity.
Six layers of defence that turn your SME into a digital fortress, without the need for an in-house IT team dedicated to security.
Security Audit
We carry out complete penetration tests (pentesting) on your infrastructure. We simulate real attacks — both external and internal — to identify every vulnerability before criminals do. We analyse the network, servers, web applications, email configuration and access policies. We deliver a detailed executive report with risk prioritisation by severity and a step-by-step remediation plan.
Email & Phishing Protection
We implement advanced AI-powered email filters that block 99.7% of phishing attacks before they reach your employees' inboxes. We configure DMARC, SPF and DKIM to prevent attackers from spoofing your company domain in attacks on third parties. We add attachment sandboxing to detect zero-day malware and real-time malicious link protection.
Access Management & MFA
A password alone is not enough. We activate multi-factor authentication (MFA) on the systems your company already uses — Microsoft 365, Google Workspace, ERP, CRM and cloud. To log in, the employee needs the password plus a confirmation on their mobile: if the password is stolen in a phishing attack, the attacker is locked out. For legacy systems without native MFA, we set up a single sign-on (SSO) gateway with Microsoft Entra ID or Duo. Each person only accesses what they need for their role, and when they leave the company they lose access immediately. Blocks 99.9% of attacks based on stolen credentials.
Backup & Disaster Recovery
Encrypted automatic backups following the 3-2-1 rule: three copies of the data, two different media types, one offsite copy in a secure datacenter. We test the restore monthly to ensure it works when you need it. Guaranteed recovery time (RTO) under 4 hours for critical systems. Disaster recovery plan documented and tested every six months.
24/7 Monitoring
Our SOC (Security Operations Center) monitors your network 24 hours a day, 7 days a week, 365 days a year. We detect suspicious activity in real time — intrusion attempts, lateral movement, privilege escalation, data exfiltration — and respond automatically before the attack materialises. Immediate alerts to your team via SMS and email.
Team Training
Security Awareness programs tailored to your team. Realistic phishing simulations that test employee resilience, practical workshops on security best practices and monthly email micro-training that keeps security awareness active. We transform your employees from a vulnerability into the first line of defence. Certificate included for every participant.
From Vulnerability to Protection in 4 Steps
A structured, transparent process designed to cause zero disruption to your business operations. No unnecessary technical jargon.
Audit
We carry out a complete analysis of your infrastructure: internal and external network, physical and cloud servers, endpoints (laptops, desktops, mobile phones), email accounts, access and password policies, firewall, Wi-Fi and VPN configurations, and GDPR compliance assessment. We identify every vulnerability and classify each risk by severity and likelihood of exploitation. We deliver a clear report, without jargon, with prioritised recommendations.
Protection Plan
Based on the audit results, we design a security plan tailored to your business. We prioritise actions by impact and cost-benefit, define the budget required for each phase and present the implementation roadmap with clear, measurable milestones. The plan is approved by management before we move forward, ensuring full transparency and alignment with the available budget.
Implementation
We install and configure every protection solution: next-generation firewall, enterprise antivirus and EDR, disk and communications encryption, MFA (multi-factor authentication) on every critical access, automated backup system with offsite replica, network monitoring and SIEM, and documented security policies. All without interrupting the company's normal operation — phased implementation and outside business hours when necessary.
Continuous Monitoring
After implementation, we monitor your infrastructure 24/7 from our SOC. We carry out quarterly penetration tests to validate the defences, update protections against new emerging threats, generate monthly security reports with clear metrics and ensure permanent GDPR compliance with the CNPD. Quarterly review meetings with your management to adjust the security strategy.

Companies That Are Already Protected
"In January they tried to attack us with ransomware — the monitoring system detected the intrusion in 4 minutes and blocked everything automatically. Without Pro Digital Key, we would have lost access to 12 years of production data. The investment in security paid for itself in that single incident."
"After the audit, we discovered 23 critical vulnerabilities we didn't know about — including former employees' accesses still active. The Pro Digital Key team resolved everything in 5 days and implemented continuous monitoring. Phishing incidents dropped 94% after team training."
"With sensitive clinical data, GDPR compliance was our biggest concern. Pro Digital Key implemented full encryption, granular access control and data retention policies. We passed the CNPD audit without any non-compliance. I recommend it to any clinic or practice."
"On a finance team we're a constant target for sophisticated phishing and wire-transfer fraud attempts. Email monitoring + regular simulations + strong auth completely eliminated fraudulent transfers — we used to see 2-3 real-risk attempts per month. The peace of mind is hard to quantify but enormous."
Frequently Asked Questions
The audit includes internal and external penetration tests, vulnerability analysis across the entire infrastructure (servers, network, endpoints, cloud), review of access and password policies, assessment of email configuration (SPF, DKIM, DMARC), Wi-Fi security testing, verification of backups and restore processes, GDPR compliance analysis and a complete executive report with all findings prioritised by risk level and a detailed remediation plan with deadlines and owners.
Yes, all our solutions are designed to fully comply with the General Data Protection Regulation (GDPR) and the specific guidelines of the Portuguese Data Protection Authority (CNPD). We implement privacy policies, records of data processing activities, impact assessments (DPIA), data breach notification procedures within 72 hours and data processing agreements compliant with Article 28 of the GDPR. We keep all documentation up to date and prepare your company for any regulatory inspection or audit.
Our incident response SLA is 15 minutes for critical incidents (active ransomware, confirmed intrusion, ongoing data exfiltration) and 1 hour for medium-severity incidents (unauthorised access attempts, malware detected and contained). 24/7 monitoring allows us to detect threats in real time and initiate containment automatically in many cases, even before contacting your team. We provide a dedicated emergency line accessible 24 hours a day, 365 days a year, staffed by specialists in incident response.
No. We use next-generation security solutions based on cloud and artificial intelligence that have negligible impact on system performance — typically less than 2% additional CPU usage. Network monitoring is passive and does not interfere with normal data traffic. In fact, many companies report performance improvements after implementation, because we eliminate hidden malware, suspicious background processes and unauthorised network traffic that were consuming hardware resources and bandwidth without the IT team's knowledge.
