Law No. 5651 obligations for hosting companies cannot be closed with a simple “do we have a logging appliance?” question. Companies that provide hosting services often operate close to the hosting provider role under Law No. 5651. That creates operational responsibilities such as keeping identifying information up to date, responding to unlawful-content notices through the right process, retaining traffic data within the legal retention frame, and protecting the accuracy, integrity, and confidentiality of records.
This guide gives technical teams at hosting and data center companies a practical compliance framework. It is not legal advice; concrete legal interpretation should be handled with your legal counsel. The goal here is to clarify which technical and operational controls should exist.
Quick Summary
- Law No. 5651 regulates the obligations of content providers, hosting providers, access providers, and collective-use providers on a role-based basis.
- A hosting provider is the person or legal entity that provides or operates systems hosting services and content; hosting companies are commonly assessed in this category.
- A hosting provider is not generally required to monitor every hosted content item, but must act when it is notified of unlawful content under the procedure defined by law.
- Hosting providers must retain traffic data for a period between
1 yearand2 yearsand protect the accuracy, integrity, and confidentiality of that information. - BTK's hosting provider list and notification processes make operational inventory and public contact information important for hosting companies.
- Law No. 5651 records may also contain personal data under KVKK, so log security, access control, and disposal plans should be designed together.

Which Law No. 5651 Role Applies to a Hosting Company?
Under Law No. 5651, a hosting provider is defined as the person or legal entity that provides or operates systems hosting services and content. This is directly relevant for companies offering web hosting, server hosting, virtual servers, reseller hosting, or managed hosting services.
For hosting companies, role analysis is the first control:
| Service model | Possible Law No. 5651 role | Operational interpretation |
|---|---|---|
| shared web hosting | hosting provider | customer content and hosting logs should be separated |
| VPS/VDS or cloud server | hosting provider, with extra role analysis in some flows | traffic data and customer isolation must be clear |
| colocation | depends on contract and technical operation model | physical hosting and service management should be separated |
| hosting only the company website | mostly content provider | role chain changes if hosting is outsourced |
| providing internet access | access provider or collective-use provider dimension may appear | access logs and hosting logs should not be confused |
Without this separation, claiming “Law No. 5651 compliance” is weak. Content provider, hosting provider, and access provider obligations are not the same. A hosting company should first document which role it has for each service.
What Are the Core Obligations of a Hosting Provider?
In practice, hosting companies face these core areas under Law No. 5651.
Keeping identifying information current
The law requires content, hosting, and access providers to keep identifying information accessible and current under the procedures defined by regulation. For a hosting company, this means more than having a contact page. Legal name, contact channel, support path, and legal notice workflow should work correctly.
Responding to unlawful-content notices through process
A hosting provider is not generally required to monitor hosted content continuously. However, if it is properly notified of unlawful content, it should have an operational flow that can act. That makes abuse desk routing, ticket classification, customer notification, and action records part of the technical service process.
Retaining traffic data
Hosting providers are expected to retain traffic data under the legal framework and protect the accuracy, integrity, and confidentiality of that information. The common mistake is assuming that web server access logs alone satisfy every Law No. 5651 need.
Maintaining BTK notification and inventory discipline
BTK's hosting provider list and notification area are an external compliance signal for hosting companies. If notification data, legal name, domain, IP ownership, contact channels, and technical ownership are not maintained, audits and incident response slow down.
How Should Traffic Data and Log Retention Be Designed?
Traffic data under Law No. 5651 is not just a text log file. The law's definition includes IP address, port information, service start and end time, service type, transferred data volume, and subscriber identity information where available. For a hosting company, these records may appear across several layers:
- web server access logs
- control panel and customer session records
- NAT, firewall, and load balancer logs
- DNS and proxy logs
- hypervisor, virtual network, and cloud panel events
- support ticket and abuse-action records
A strong technical model should include:
- central time synchronization and NTP standards
- log source inventory
- immutable or integrity-verifiable archiving
- access right separation
- customer-level correlation and search capability
- retention and disposal procedure
- SIEM or log management correlation
At this layer, SIEM and Security Event Management Integration under Hardware and Software Solutions strengthens not only storage of logs, but also incident review and integrity control. To identify governance and control gaps, Cybersecurity Assessment Service under Business Management Services is directly relevant.
How Should Takedown and Access-Blocking Notices Be Managed?
One risky area for hosting companies is treating a legal or official notice like an ordinary support ticket. In Law No. 5651 processes, speed, record integrity, and authority separation matter.
Use this practical workflow:
- separate the notice channel: abuse, legal, support, official notification.
- classify the request type: content removal, access blocking, information request, customer complaint.
- verify the customer and service relationship.
- record the legal request and technical action separately.
- retain action date, operator, related domain/IP, and evidence set.
- apply customer notification and internal escalation policies.
The Access Providers Association's official FAQ explains its coordination role under Article 6/A for certain access-blocking and content-removal decisions. Even if a hosting company is not directly an access provider member, it should operationally track how those decisions affect customers and hosted content.
How Does the KVKK and Law No. 5651 Intersection Affect Hosting Companies?
For hosting companies, Law No. 5651 logs often carry a personal-data dimension. When IP address, timestamp, user account, customer number, support ticket, and access record come together, the dataset may need protection under KVKK.
The separation is important:
- Law No. 5651 explains why certain records are retained.
- KVKK affects the personal-data dimension, access rights, security, and retention discipline of those records.
Technical requirements include:
- restrict log access by role
- prevent support teams from accessing all raw logs by default
- record sensitive log searches
- keep the same security level in backup and archive copies
- run disposal or anonymization after the retention basis ends
This topic should be read with What Is the Difference Between Law No. 5651 and KVKK?. Strong compliance for a hosting company means operating both frameworks on the same record set, not treating one as a replacement for the other.

Frequently Asked Questions
Is a hosting company a hosting provider under Law No. 5651?
Most hosting services create a hosting-provider role, but the final assessment depends on the service model, contract, and technical operation structure.
Is a hosting provider required to monitor customer content continuously?
Generally no. A hosting provider is not required to monitor all hosted content continuously, but it must operate the required process if properly notified of unlawful content.
Which logs should be retained for Law No. 5651?
It is not limited to one file name. Layers that generate IP address, port, time, service type, transferred data volume, and customer/subscriber association should be assessed together.
Are Law No. 5651 logs within KVKK scope?
Records linked to IP, user, customer, or subscriber information may carry a personal-data dimension. Log security and access control should therefore be designed with KVKK in mind.
Is retaining logs enough?
No. Accuracy, integrity, confidentiality, access rights, time synchronization, retention period, disposal, and incident review process should be designed together.
