Is my site blocked on Orange in Poland?
Orange Polska blocks sites from four sources: the Finance Ministry's gambling register, CERT Polska's phishing warning list, a list of disinformation sites tied to the war in Ukraine, and its own detections in CyberTarcza, a free filter that covers every Orange internet customer and cannot be switched off. A blocked visitor is sent to Orange's servers, so on an https site they usually see a certificate warning before any explanation. Orange's own checker tells you whether a domain is blocked on its network.

What does CyberTarcza block on Orange's network?
CyberTarcza blocks domains and single server addresses that CERT Orange Polska, Orange's security team, links to phishing, fraud or malware. Orange says the team adds hundreds of domains and addresses every day. It applies to every customer of Orange's internet services, whatever the type of service, so home and mobile lines are both covered. Orange describes the gambling register, CERT Polska's list and the disinformation list as further sources of what CyberTarcza blocks. How CyberTarcza fits next to the national lists is on the Poland page.

In the first half of 2026 CERT Orange Polska blocked 330,000 fake domains used to steal data or money, 30% more than in the same period of 2025, and 3.2 million customers who tried to open them were told the site had been blocked. In 2025, almost 70% of the fake sites it blocked were fake investment offers.

What does an Orange customer see when your site is blocked?
Usually a browser security error first. Orange sends blocked traffic to its server sh.cert.orange.pl and forwards phishing traffic to alert.cert.orange.pl, where its warning page lives. Over https Orange accepts the connection with its own certificate (a site's proof of identity), issued for Orange's domain, not yours. The browser then reports a bad certificate, an HSTS error (HSTS is a setting by which a site tells browsers to accept only secure connections to it) or a possible interception. Orange itself advises not to accept certificates that do not match the address of the site you meant to open. To the visitor, your site looks broken. Why a warning costs you visitors: red warnings and lost visitors.

Is Orange mobile filtered differently from Orange home internet?
The free filter is the same on both, but Orange also sells a paid add-on under the same name. CyberTarcza mobilna works only on Orange's mobile network in Poland, covers three numbers in its price and lets the customer block ads and whole categories of sites. So if only a few Orange mobile users cannot open your site, a category rule set on their account is one possible cause, next to the free filter. The reverse does not work: Orange says that allowing a site in the paid service does not lift a block by the free filter, which takes priority.

Who can lift a wrong block on Orange?
That depends on which list your domain is on, so check that first. Enter the domain in Orange's domain checker to see whether Orange blocks it at all. Then search CERT Polska's list and the gambling register, as described on the Poland page.
- On CERT Polska's list. Orange follows the list; the formal route is an objection to UKE, Poland's telecom regulator, explained on the Poland page.
- In the gambling register. The objection goes to the Minister of Finance, also explained on the Poland page.
- On neither. The block is most likely Orange's own detection. Orange asks for reports to cert.opl@orange.com, a mailbox its team watches 24 hours a day. It publishes no separate form and no time limit for site owners.
Orange admits that among tens of millions of events some are wrongly classified, and says such cases are few. Its public report form on cert.orange.pl is for reporting threats, not for disputing a block.

What does linkspect check on Orange?
We open your URL through the home broadband connections of Orange customers in Poland. Orange mobile can be included in a check: we measure it when we have a suitable test connection at the time, and otherwise that answer says "not measured". If Orange's network answers with a certificate that is not yours, the result says so. Other Polish providers: T-Mobile and Netia.
