Is my site blocked on Play in Poland?

Play, run by the company P4, blocks the domains on two national lists: the Finance Ministry's register of illegal gambling sites and CERT Polska's list of phishing domains. On top of that, Play sells its own filter, Bezpieczny Internet ("safe internet"), which blocks pages it judges dangerous for the mobile and home customers who switch it on. If a Play customer says your site does not open, search both lists first, then ask whether that customer has the filter.

Which official blocks does Play apply?

The same two national lists as other big Polish providers. Every internet provider in Poland must send visitors of a domain in the gambling register to a Finance Ministry notice saying the site offers gambling illegally. P4, as the operator of Play, signed the March 2020 agreement under which providers block the domains on CERT Polska's warning list in their DNS (the internet's address book, which turns a domain name into a server address). How both lists work, and what gets a legitimate site onto them, is on our Poland page.

What is Play's Bezpieczny Internet filter?

Bezpieczny Internet is a paid filter inside Play's network that a customer has to order. When Play launched it in November 2021, it was for contract, MIX and prepaid mobile customers, it cost 6 złoty a month after a free first month, and it ran in the network on the customer's phone number, with no app to install. The technology comes from Allot, an Israeli security company: Telepolis reported that Play uses Allot's NetworkSecure product, and the filter's terms name Allot Ltd. as the company that licenses the service to P4.

Play's current product page says the filter guards against worms and viruses, spyware, phishing, malware and botnets, and offers it for "mobile devices or the whole home network". Why a warning in front of your page costs you visitors: red warnings and lost visitors.

Is Play home internet filtered the same way as Play mobile?

Not quite: home lines get their own version. On 30 May 2025 Play extended the filter to its fibre customers as Bezpieczny Internet dla Domu. It works in the network and covers every device on the home Wi-Fi, guests included. It cost 6.99 złoty a month with a new 12- or 24-month contract, or 9 złoty a month without one, at launch. On mobile, as launched in 2021, the filter covered only the device with the Play SIM card for the number it was ordered on, while using Play's internet; protection on Wi-Fi needed a separate app. So one customer can be filtered on the phone and not at home, or the other way round.

Play bought UPC Polska on 1 April 2022 and merged it into P4 on 31 August 2023. UPC is now Play.

What does a Play customer see instead of my site?

It depends on which block hit. For a domain in the gambling register, it is the Finance Ministry's notice. When Play launched its filter in 2021, it said the phone would show a notification warning about the threat. Play also runs a warning page at blokada.play.pl. Its heading reads "Wykryliśmy zagrożenie" ("we have detected a threat"), and it says the page you want to open is potentially dangerous and could steal your personal data, logins and passwords. Play's pages that we read do not say which blocks lead there.

Who can lift a wrong block on Play?

It depends on which list your domain is on. For the gambling register, the domain holder can object to the Minister of Finance. For CERT Polska's list, the objection goes to the head of UKE, Poland's telecom regulator. Both have deadlines and formal rules, explained on our Poland page.

For a block by Bezpieczny Internet, Play documents no route for a site owner, and we found none from Allot either. The filter's terms let Play customers send complaints and questions about the service to Play's customer service, for example by e-mail to ok@pomocplay.pl. abuse@play.pl is the network's abuse contact listed in RIPE, the public register of European network operators; it is not described as a way to contest a block.

How can I check my site on Play myself?

Search your domain on hazard.mf.gov.pl and in CERT Polska's list, which you can download as plain text. A customer on a Play connection can open lista.cert.pl to see whether that connection uses CERT Polska's list. If your domain is on neither list, ask the customer whether Bezpieczny Internet is switched on; at its 2021 launch Play said customers could order it in the Play24 app, in Play shops or by phone. The lists show what should be blocked, not what each visitor sees.

What does linkspect check on Play?

We open your URL through the home broadband and mobile connections of Play customers and give a separate answer for each. On Play mobile, a block in the DNS is reported as "likely" at most, because we see only what the customer's phone received. Other Polish providers: Plus, Orange, T-Mobile and Netia.
