NetherlandsChecked 18 August 2026
Depends on your industryWork: HighEnforcement: Aggressive
- In one paragraph
- For most businesses the Netherlands follows the ordinary European rules: data may leave the country once you have the right paperwork in place. Two areas are much harder. Online gambling firms must keep their regulator-facing database physically in the Netherlands, and central government now has to keep all its information inside Europe. The Dutch privacy regulator hands out some of the largest transfer fines in Europe.
- The catch
- The relaxed headline stops being true the moment you touch online gambling, central government work, health records or a regulated financial firm. An online gambling licence forces one database onto Dutch soil. Central government contracts now bar storage outside Europe. And a brand-new cybersecurity law switched on three days ago, on 15 August 2026, with a 24-hour incident alarm most companies have not built yet.
- Does this apply to me?
- Yes, it reaches you with no Dutch office. Europe's privacy law applies to any organisation anywhere that offers goods or services to people in the Netherlands or watches what they do online, and there is no size or revenue floor. Separately, the new Dutch cybersecurity law says that if you are a cloud provider, data centre, managed service provider, online marketplace, search engine or social network based outside Europe but selling into the Netherlands, you must appoint a representative inside the European Union.High confidence
- Can the data leave the country?
- In general yes, with paperwork, because the Netherlands is an EU country and European rules govern transfers. But three Dutch walls override that. An online gambling licence holder must physically place its regulator-facing control database in the Netherlands. Central government must keep all its information inside the European Economic Area plus Switzerland. And a healthcare provider, bank or insurer can put data abroad only if the supervisor can still see and audit it.High confidence
- What do I have to do to send it abroad?
- The model is an allowlist run at European level, not a Dutch one. You may send personal data outside Europe only if the destination has been officially approved, or you sign the standard European contract, or you use approved group-wide rules. The approved list is full and active. The Netherlands adds no national approval step and keeps no blocklist of its own.High confidence
- Who enforces this — and are they actually working?
- The Dutch Data Protection Authority, and it is very much operational and very much willing to fine. It has a full three-person board, and a new chair, Geert Potjewijd, took office on 1 August 2026. It has issued two of the largest cross-border transfer fines in Europe: 290 million euros against Uber in 2024 and 100 million euros against a taxi app in May 2026. Cybersecurity is enforced separately, by sector ministries and inspectorates, and that machinery is only now being assembled.High confidence
- How long must I keep it, and when must I delete it?
- There is a firm floor and a soft ceiling. You must keep your books and tax records for seven years, and money-laundering records for five years after the relationship or transaction ends. Against that, privacy law says you must delete personal data once you no longer need it, and there is no fixed number. When the two collide, the legal duty to keep wins for as long as it lasts, and deletion follows immediately after.High confidence
- What happens when something goes wrong?
- Count three clocks, not one. For a personal data breach you have 72 hours to tell the Dutch Data Protection Authority. If you are covered by the new cybersecurity law that started on 15 August 2026, you must raise an early warning within 24 hours, file a full report within 72 hours, and deliver a final report within one month. Telecom operators have a fourth clock and must tell the privacy regulator without delay.High confidence
- What's the trap?
- Five things that are not in the summary. Your works council can block an HR or monitoring system. Breaking a professional secrecy duty is a crime, not a fine. The telecom retention duty printed in the law cannot be enforced. Children need a parent's permission until they turn sixteen. And the new cybersecurity law started on 15 August 2026 with a phased exception for universities that most checklists miss.High confidence
- What's about to change?
- Three dated changes. On 1 September 2026 an amendment act tidies up the Dutch privacy law and adds new rules for handing over health files, but one part of it has deliberately been left switched off. Registration and incident duties under the cybersecurity law that started on 15 August 2026 are being phased in now. And by 12 January 2027 every cloud provider must drop switching and data export charges to zero across Europe.High confidence

GreeceChecked 18 August 2026
Depends on your industryWork: HighEnforcement: Active
- In one paragraph
- For most businesses Greece is a normal European country: personal data can leave, as long as you use one of the standard European transfer tools. But Greece has two hard walls that Europe does not. Phone and internet connection records must physically sit on machines inside Greece. Online gambling operators must keep their records on a server inside Greece too. The privacy regulator is fully staffed and fining companies today.
- The catch
- The relaxed European headline stops being true the moment you touch three things. Telecoms connection records must be stored on physical media inside Greek territory for twelve months. Online gambling records must sit on a server or safe inside Greece for ten years. And Greek public bodies must run their central systems on the Greek state's own clouds, not on a commercial cloud of their choosing. Outside those three, plus the health and public sectors, Greece imposes no storage-location rule of its own.
- Does this apply to me?
- Yes, it reaches a foreign company with no office in Greece. The European privacy rules apply to anyone anywhere who offers goods or services to people in Greece, or who watches what they do online. The Greek national law adds that it also covers anyone processing data on Greek soil. There is no size or revenue threshold that lets you off. If you have no establishment anywhere in Europe, you must appoint a written representative inside the European Union.High confidence
- Can the data leave the country?
- In general, yes. Greece adds no storage-location rule of its own to the European baseline, so ordinary business data can be sent abroad once you have the right European transfer paperwork. Three industries break that rule completely. Telecoms companies must keep their connection records on machines physically inside Greece. Online gambling operators must keep their records on a server inside Greece. And Greek government bodies must run their main systems on state-operated clouds. Health, banking and insurance have extra hoops but no location rule.High confidence
- What do I have to do to send it abroad?
- You need one of the standard European transfer tools before data leaves Europe. The simplest is sending it to a country the European Commission has already approved. If the destination is not approved, you sign the European Commission's standard contract with the recipient, or use approved group-wide internal rules, and you write down why you think the data will still be safe there. Greece adds no extra permission, filing or fee of its own.High confidence
- Who enforces this — and are they actually working?
- Six bodies, and all six are genuinely working. The Hellenic Data Protection Authority is the main privacy regulator and is issuing numbered decisions and fines every month — its most recent published decisions run to July 2026 and include fines on a bank and an electricity supplier. A separate constitutional authority polices the secrecy of communications. There is also a national cybersecurity authority, a telecoms regulator, the central bank for finance and insurance, and a gambling regulator. This is not a paper regime.High confidence
- How long must I keep it, and when must I delete it?
- Both directions apply, and they collide. Business books must be kept five years. Medical files must be kept ten years in a private practice and twenty years everywhere else. Online gambling records must be kept ten years. Telecoms connection records must be kept exactly twelve months and then automatically deleted. In the other direction, the European rule says you must not keep personal data longer than you need it. When a specific keeping rule and the general deleting rule clash, the specific keeping rule wins.High confidence
- What happens when something goes wrong?
- Count three clocks, not one. If personal data is lost or exposed, you have 72 hours to tell the privacy regulator. If you run important infrastructure, you have only 24 hours to send a first warning to the national cybersecurity authority, then 72 hours for a fuller report and one month for the final one. If you are a phone or internet provider, you have 24 hours to report a personal data breach and a separate duty to tell the communications secrecy authority. Missing the 24-hour clocks is the most common failure.High confidence
- What's the trap?
- Five things that will cost you a weekend. First, a child in Greece can consent to an online service at fifteen, not sixteen — so an age gate built to the European default is set wrong. Second, misusing personal data is a crime here, with prison time, not just a fine. Third, several articles of the Greek privacy law are printed in the statute but the regulator has formally said they must not be applied, because they clash with European law. Fourth, telecoms connection records must physically stay in Greece. Fifth, government bodies cannot simply pick a commercial cloud.High confidence
- What's about to change?
- Three dated changes. Electronic invoicing between businesses became compulsory for large Greek companies on 2 March 2026 and becomes compulsory for everyone else on 1 October 2026. Greece's new artificial intelligence law took effect on 22 July 2026 and forces public bodies to register every artificial intelligence system before switching it on. And from 12 January 2027 European law bans cloud providers from charging you to move your data out.High confidence
