Nuuday Annual Report 2025 51
Cyber Security Day and Hele Danmark
Øver, to strengthen national cyber resi-
lience. These platforms unite prominent
speakers and stakeholders from both the
public and private sector to raise aware-
ness and share knowledge. Such initiati-
ves and platforms reflect TDC Erhverv’s
role in strengthening societal resilience
through public-private collaboration,
ensuring preparedness and trust in
Denmark’s critical digital infrastructure.
TDC Erhverv’s DNS InternetFilter solution
blocks millions of cyberattack attempts
every quarter, protecting and alerting
our business customers from entering
malicious domains – whether through
links in emails, SMSs, or other sources
– and blocks typical hacker attacks like
malware, phishing, and botnets.
2025 performance and 2026 outlook
This year, YouSee has integrated and
added MobilSikker, its own mobile DNS
security filter, to all consumer customers,
which also protects customers from
entering malicious domains on the mobile
network. Moreover, YouSee routers with
built-in security blocked harmful content
more than 336 million times in 2025, which
is more than 650 attempts per household.
Both YouSee’s MobilSikker and TDC
Erhverv‘s InternetFilter reflect Nuuday’s
commitment to providing peace of mind
for customers in an era where IT crime is
at an all-time high.
Through reports, such as “Are organisa-
tions ready for tomorrow?” and quar-
terly security reports, TDC Erhverv has
brought important data and insights about
the current threat landscape to market,
cementing its position as an important
actor within the cybersecurity agenda.
Overall, we have further strengthe-
ned our cybersecurity position in TDC
Erhverv, adding to our existing strong po-
sition as a thought leader and prominent
societal actor. A position that has been
obtained through our insights and data
reports, events during the year, the use
of experts in media and through closer
collaboration and engagement with part-
ners, other industries, and the govern-
ment, e.g. TDC Erhverv’s participation in
the national safety forum Ehvervs-
Forum. At YouSee, we launched strong
initiatives enhancing the protection of
the average consumer when online.
Our ambition for 2026 is to continue
strengthening our cybersecurity position,
especially within our consumer brands
and offerings for our consumer and busi-
ness divisions, while further enhancing
synergies between them. This will be
achieved through expanding the reach
and number of partnerships, events, and
collaborations, and cementing cyber-
security as a key enabler for a secure,
connected digital future for Danish
society.
Looking ahead, TDC Erhverv is already
preparing for the next digital era by
testing quantum-secure encryption solu-
tions to protect against future emerging
threats, since in a few years quantum
computers might be able to break the
encryption, we know today.
Why this is important for Nuuday
In the telecommunications industry, main-
taining strong and compliant operations
and the value chain is vital for delivering
reliable services, protecting customer
data, and ensuring adherence to regula-
tory obligations. For Nuuday, compliance
is not just about meeting legal require-
ments; it is a core enabler for ethical, ef-
ficient, and responsible operations across
the entire value chain.
From sourcing network equipment and
software to deploying and maintaining
infrastructure and serving millions of
customers, compliance ensures that
every action is guided by clear standards
and ethical principles.
We follow a suite of policies and proce-
dures that are overseen by the Board
of Directors and made publicly available.
These cover our code of conduct policy,
which was launched in 2025 and sets a
clear value-based framework for be-
haviour across key topics, whistleblower
policy, anti-bribery and anti-corruption
policy, data ethics policy, and partner
code of conduct policy, including our ap-
proach to human and labour rights, The-
se policies are maintained and reviewed
annually by the relevant administrators
and approved by the Board of Directors.
The overall responsibility lies with ELT.
We aim to ensure the highest standards
in order to take care of our employees
while meeting stakeholder expectations.
We therefore have two ISO certifications
across our business, covering environ-
mental management (ISO 14001) and
occupational health and safety (ISO
45001), while TDC Erhverv holds an
information security certification (ISO
27001) for a part of its business.
Human rights, anti-bribery and
anti-corruption
Nuuday is a large employer in Denmark
with suppliers across the globe and has
responsibility for our direct employees,
the employees of partners and compani-
es in our supply chain. Human rights and
anti-corruption are important topics for
Nuuday and its operations, and we firmly
denounce bribery and do not tolerate or
accept corruption in any form. Also, we
believe that human rights are inalienable
and must be respected by Nuuday’s
suppliers.
Nuuday is a signatory to the UN Global
Compact, and we are guided by its Ten
Principles. We uphold high professional
standards in human rights, labour rights,
health and safety, anti-corruption, infor-
mation security, data protection and en-
vironmental management, and we expect
our suppliers and partners to share this
commitment and act accordingly throug-
hout their operations and support chains.
To ensure proper conduct of employees
and partners, we have an anti-bribery
and corruption policy that guides internal
behaviours, as well as a partner code of
conduct covering anti-bribery, corruption
prevention, and respect for human rights,
that suppliers and partners must obey.
A culture of compliance strengthens trust
with regulators, customers, suppliers, and
Trust across the value chain
