User privacy concerns are exacerbated by Superonline's extensive data collection practices, processing personally identifiable information, contact data, subscription details, network traffic, location data, payment information, and usage patterns, operating within Turkey's restrictive legal framework that has been documented by Freedom House as increasingly authoritarian.<ref>{{cite web |url=https://freedomhouse.org/country/turkey/freedom-world/2023 |title=Turkey: Freedom in the World 2023 |website=Freedom House |publisher=Freedom House |date=4 November 2023 |access-date=3 June 2025}}</ref> Regarding market control, Superonline operates as the largest alternative ISP with approximately 15% of the broadband market share in 2021, positioning itself as the leading challenger to dominant player Türk Telekom which holds 65.3% market share.<ref>[https://www.btk.gov.tr/uploads/pages/pazar-verileri/ceyrek-raporu-2021-4-ceyrek-22-03-21-kurum-disi.pdf BTK Market Share Statistics 2021 Q4]</ref>

==Incidents==

===Blue Coat Incident (2013)===

There are allegations and discussions that Superonline uses Blue Coat products for censorship. Products manufactured by Blue Coat Systems are known as "dual-use" technologies that can be used to defend corporate networks, as well as by governments to censor the internet and monitor public internet traffic. These devices can see some encrypted traffic, block websites or record website traffic.<ref>[https://citizenlab.ca/2013/01/planet-blue-coat-mapping-global-censorship-and-surveillance-tools/ Planet Blue Coat: Mapping Global Censorship and Surveillance Tools]</ref>

In 2011, a hacktivist group called Telecomix claimed that Syria was using Blue Coat Systems products to censor the internet and these allegations were investigated by the US government. Citizen Lab's research has also provided evidence of Blue Coat devices being used for censorship and surveillance in countries like Turkey and Syria.<ref>[https://www.eff.org/deeplinks/2011/10/blue-coat-acknowledges-syrian-government-use-its-products Blue Coat: Concern for Criminal Penalties, Not Human Rights]</ref>

===Fair Usage Terms Incident (2012-2019)===

===Injecting ads into websites (2017)===

Superonline has been criticized for injecting various advertisements into its customers' web connections while they browse the internet, thereby forcing them to watch the advertisements. Requests for clarification to the company went unanswered. This incident was described as the first evidence of traffic monitoring and manipulation through deep packet inspection in Turkey.<ref>{{cite web|last1=Gözütok|first1=Ahmet|title=Turkcell Superonline kullanıcılarını reklam izlemeye mi zorluyor?|url=https://www.donanimhaber.com/operatorler--kurumsal-haberler/haberleri/Turkcell-Superonline-kullanicilarini-reklam-izlemeye-mi-zorluyor.htm|website=donanimhaber.com|access-date=19 June 2017|archive-url=https://web.archive.org/web/20170619141204/https://www.donanimhaber.com/operatorler--kurumsal-haberler/haberleri/Turkcell-Superonline-kullanicilarini-reklam-izlemeye-mi-zorluyor.htm|archive-date=19 June 2017}}</ref><ref>{{cite web|last1=Yagiz|title=İddia: Superonline kullanıcılarına izinsiz reklam gösteriyor.|url=https://medium.com/@anonrig/i%CC%87ddia-superonline-kullan%C4%B1c%C4%B1lar%C4%B1na-izinsiz-reklam-g%C3%B6steriyor-ba555360424|website=medium.com|date=25 September 2016|access-date=19 June 2017|archive-url=https://web.archive.org/web/20170619141143/https://medium.com/@anonrig/i%CC%87ddia-superonline-kullan%C4%B1c%C4%B1lar%C4%B1na-izinsiz-reklam-g%C3%B6steriyor-ba555360424|archive-date=19 June 2017}}</ref> This problem has since been fixed and the development of HTTPS technology has made it very difficult for this to happen again.<ref>[https://docs.google.com/spreadsheets/d/1xZPAw1uCdLqDz8F_Vz57DRvCNJTcCnPgtG7P-yeloUc/edit?usp=sharing Web Hacking Incident Database]</ref>

On February 6, 2023, the company was criticized for internet outages at critical moments during the massive earthquakes centered in Kahramanmaraş, Turkey. Immediately after the earthquake disaster, the collapse of the internet infrastructure, which was critical for search and rescue operations and coordination, left both citizens and government agencies in a difficult situation. In the aftermath, Superonline was severely criticized for its lack of infrastructure resilience and emergency preparedness.  

==Controversies==

===PPPoE/WAN Password Restrictions===

===Disabling Root Accounts and Firmware Restrictions===

Turkcell Superonline's decision to restrict or completely disable access to the root account on the modems it rents to its users has sparked controversy among users. Superonline does not allow the use of third party modems. The firmware of the modems provided by Superonline is often customized and restricted, preventing users from gaining root access via web interface, telnet or ssh. One of the main reasons for this is that modem firmware updates and management are centralized by Superonline. It is argued that this centralized management may become more difficult if users have root access. While some users have stated that they need root access to configure their modem's settings in more detail, to install alternative firmware (like OpenWRT or Asus Merlin Firmware), or to enable/disable certain features, they have encountered this restriction by Superonline. In particular, some modem models are reported to disable features such as backups and manual updates via files in order to make it more difficult to obtain the root password. Some modem models have also been reported to disable the ability to change the main DNS server.<ref>[https://wf.lavatech.top/ave/router-misadventures Router Misadventures: Dumping Superonline's ISP Fiber Router]</ref>

===Censorship Using Deep Packet Inspection===

Superonline is one of the most active utilizers of deep packet inspection (DPI) technology among internet service providers in Turkey, operating within a regulatory environment that Freedom House describes as systematically restricting online freedoms.<ref>{{cite web |url=https://freedomhouse.org/country/turkey/freedom-net/2023 |title=Turkey: Freedom on the Net 2023 |website=Freedom House |publisher=Freedom House |date=10 October 2023 |access-date=3 June 2025}}</ref> With this technology, Superonline applies content-based censorship by analyzing users' internet traffic in detail, implementing policies that align with Turkey's broader approach to internet control documented by Freedom House as part of the country's "Not Free" internet status.<ref>{{cite web |url=https://freedomhouse.org/country/turkey |title=Turkey Overview |website=Freedom House |publisher=Freedom House |date=31 March 2025 |access-date=3 June 2025}}</ref>

Unlike traditional packet inspection, DPI technology also scans the content of data packets and provides the ability to detect and block VPN protocols. According to user reports, Superonline has one of the most strictly censored internet service in Turkey, and in the past has taken measures strict enough to completely block VPN protocols such as WireGuard. It also blocks or throttles popular VPN services and their websites such as Cloudflare Warp (connection itself), ProtonVPN (throttles the website), Surfshark (throttles the website, up-to-date info required for connection), Psiphon (connection itself), NordVPN (throttles the website, up-to-date info required for connection) and constantly tightens its DPI-based scanning systems.
