German companies face many cyber attacks these days. The latest reports from the BSI show that around 89 percent of firms in Germany dealt with at least one attack in the last three years. This number sits higher than in most other countries. Ransomware alone hit the German economy hard and caused about 179 billion euros in losses back in 2024. Attacks keep growing on factories, power systems, and small and medium businesses across the country.

New rules from the BSI Act now make strong cybersecurity a top job for company leaders. This applies to car part makers in Baden-Württemberg, banks in Frankfurt, and big production sites in North Rhine-Westphalia. Many German bosses now look for better ways to protect their data and systems.

What Does ZTNA Mean?

What is ZTNA? Think of it as a smart door system for your company’s apps and files. ZTNA lets the right people reach only the exact tools they need. It never puts them on the full company network. Nothing sits open on the internet.

Old security puts a wall around everything and trusts people once they get inside. ZTNA works the other way. It checks every single request again and again. It looks at who you are, what device you use, where you sit, and what time it is.

The German BSI likes this idea a lot. They say zero-trust methods cut the damage when something goes wrong. If one account gets stolen in a Munich office or a supplier in Leipzig tries to log in, the attacker cannot jump around the whole system. This matters a lot in Germany because supply chain attacks hit Industrie 4.0 factories more and more.

ZTNA grew stronger when companies moved work to the cloud and staff started working from home after the pandemic. German firms now use AWS in Frankfurt, Azure Germany, or their own private clouds. Staff sit in home offices in Hamburg or travel inside the EU. ZTNA creates a hidden path that only opens for checked users.

The main ideas behind ZTNA are easy:

• Check every user and device every time
• Give only the smallest access needed
• Split systems into small, safe parts
• Watch everything all the time
• Reach single apps instead of the whole network

For German companies that must follow GDPR Article 32 and new BSI cloud rules, ZTNA gives clear records. Data stays inside Germany or the EU when possible. This helps with Schrems II rules too.

How ZTNA Actually Works

Let us walk through a normal day with ZTNA. A worker in Berlin opens the company payment system. Or a partner in Stuttgart needs to see one drawing file.

• First, the person asks for access. The ZTNA system checks many things at once. It looks at the login with extra codes, the job role, the laptop health, the location inside Germany, and if the behaviour looks normal.
• Next, it decides yes or no based on clear rules. A finance person in Frankfurt can open SAP only during office hours from a company laptop. A helper from outside gets to read one folder only.
• When everything checks out, the system builds a safe, direct link straight to that one app. The app stays hidden from the whole internet. No open ports, no public address.
• Even after the link starts, the system keeps watching. If the laptop suddenly shows a virus or the user starts acting strangely, the link closes right away.

Good ZTNA tools offer two ways. One uses a small program on the computer. The other works straight in the browser, so outside helpers do not need to install anything. This fits well for German firms that let staff bring their own devices or work with many partners.

Sophos makes this easy. With Sophos ZTN, the system talks directly to the endpoint protection and the firewall. If a device looks risky, it blocks access automatically. German teams see everything on one screen inside Sophos Central. This helps a lot when they must send reports for NIS2 rules.

Speed stays good, too. Sophos has fast connections near Frankfurt.  

Clear Advantages of ZTNA for Companies in Germany

ZTNA brings real help to German firms. Here are the main points in plain words:

1. Stronger protection against ransomware. Attacks cannot spread easily across the company.
2. Better GDPR fit. You control exactly who sees what data and keep flows inside Europe.
3. Direct support for NIS2 and BSI rules. The checks, logs, and small safe zones match what auditors want.
4. Happier staff. People open apps without slow logins or extra steps. This helps with hybrid work that is normal now in Germany.
5. Lower costs in the long run. Less hardware, less manual work, and fewer big losses from attacks.
6. Safer work with partners. Suppliers and helpers reach only what they need without touching the main network. This is key for the connected car and machine industry in Germany.
7. Ready for tomorrow. It handles new threats, more cloud use, and machines connected to the internet.

Sophos ZTNA – A Good Fit for German Needs

Many German companies pick Sophos ZTN because it is practical. It sits inside the Sophos Workspace Protection package.

It works without a complicated setup. Users just click their app and go.  

It connects smoothly with Sophos endpoint and firewall tools. All parts share information live, so bad devices get blocked fast.

You can run it in the cloud or on your own servers in Germany. Points of presence near Frankfurt keep everything fast and data close.

It offers the small program way or the browser-only way. This helps when you work with many outside people.

Everything is managed from one place in Sophos Central with clear reports for audits.

You can start with Sophos ZTNA even if you do not use other Sophos tools yet. But when you combine them, the protection gets even stronger.

Many system houses in Germany, like Bechtle, recommend it for factories that need safe remote help for machines and for banks that must keep data inside the country.

How to Bring ZTNA into Your German Company

Follow these easy steps to start:

1. Look at what you have now. List all apps, who uses them, and where data sits.
2. Write clear rules based on jobs and BSI advice.
3. Pick the setup that fits your data rules – full cloud, mix, or own servers.
4. Test with one small team first, like the design group in Bavaria.
5. Link your current login system and extra security codes.
6. Roll it out and explain the benefits to everyone.
7. Watch the numbers and improve step by step.

Sophos gives a clear checklist, and local partners across Germany can help you move fast.

Final Words!

Old wall-style security no longer works for companies in Germany. Attacks keep coming, rules get stricter, and people work from many places. ZTNA gives the protection, rule following, and easy use that German firms need in 2026.

Whether you run a big car supplier, a medium factory in the Mittelstand, or a finance office in Frankfurt, ZTNA helps you stay safe and work more smoothly. Tools like Sophos ZTN and zSophos ZTNmake the change simple and practical.

The question today is not what ZTNA is anymore. The question is, when will your company start using it? Firms that begin now will follow the rules more easily, lose less money to attacks, and work better with partners across Germany.
