IT Security – Audits, Concepts & Protection for Your Systems

Audits, security concepts and protection for your systems. We help you find and reduce security risks.

Cybersecurity for Your Business Applications

Cyber threats are growing. Security is no longer optional. Ransomware can stop operations; data breaches can destroy trust. We help you find weak spots, set up strong protections and respond to incidents.

We think like developers. We know how apps are built and where holes appear – injection, auth flaws, bad data handling, wrong cloud settings. So we give practical, doable advice, not generic lists.

We offer security audits, penetration tests and architecture reviews. We make sure your systems are designed securely from the start. We also help with GDPR and other rules – what you must do and how to do it in practice.

We don't only report issues – we help fix them. Hardening web apps, encryption, secure CI/CD, secure coding training. We work with you to improve security step by step.

Zero Trust: Verify Everything

The Zero Trust model says no user or device is trusted by default. Every access is checked – e.g. with two-factor auth and strict roles. With a well-set VPN for remote access you get tight control and limit how far attackers can move. We help you roll out Zero Trust step by step.

Encryption at Every Layer

Encryption is one of the best defences against data theft. SSL/TLS secures browser–server traffic; end-to-end encryption keeps messages and files readable only by the recipient. A proper firewall filters bad traffic at the edge. Together you get strong, layered defence.

Backup & Disaster Recovery

No system is unbreakable. A clear backup and recovery plan is essential. We define RTO and RPO with you, set up automated backups and test restores. So you are ready even for ransomware: you can restore from clean backups instead of paying.

Frequently Asked Questions

IT Security

Audits & Ongoing Security

What does an IT security project include?

Audits, penetration tests and secure development (security by design, code reviews, hardening). We define scope and deliverables so you get a fixed quote.

How much do security audits cost?

A basic web application test from around €5,000 excl. VAT; broader audits from €15,000 excl. VAT. We give a fixed quote after a short briefing.

Is secure development part of development projects?

Often yes – we build security in from the start. We can also quote it as a separate phase so you can plan budget clearly.

What about ongoing security?

Monitoring, incident response and updates can be billed as a retainer or as part of a maintenance contract. We recommend starting with an audit to prioritise remediation.
