Overall, Cuba's internet and social media penetration is limited due to access limitations, slow network speeds, and high costs, resulting in a rather slow internet adoption. The Cuban government has attempted to expand public Wi-Fi hotspots launching 3G and 4G mobile networks. Despite these efforts, internet access in Cuba remains expensive and limited compared to other countries in the region.
According to a 2021 report by Freedom House, the Cuban government uses a range of tactics to restrict online speech, including censorship, surveillance, and intimidation of online activists. The report notes that online criticism of the government can result in arrest and imprisonment.

Brazil is the world’s eighth largest economy in terms of GDP, and by far South America’s most populous and powerful state. While the country has suffered economic and political crises since 2014, it has made significant advances in domestic digitization and played a pivotal, albeit ambiguous role in international negotiations on cyberspace. Brazil has the world’s fifth largest internet user base, after China, India, the United States and Indonesia, and is a leading country in South America when it comes to ICTs usage. The share of Brazilians using the internet has increased from less than 3% of the population in 2000 to more than 68% in 2019. As such, Brazil remains a critical partner for the EU’s efforts to build a secure, stable and rights-based cyberspace.

An EU candidate country since 2012, Serbia is an important partner in the Western Balkans. The 2020 iteration of the Digital Evolution Scorecard characterised Serbia as a ‘break out’ economy, meaning that despite a relative lack of digital infrastructure the country is rapidly digitalising; internet penetration is one of the highest across the region, standing at 79%. Over the past decade, Serbia’s digital policy has been focused on attracting foreign investment, deepening the digital transformation across the public and private sectors, and promoting economic growth in line with EU targets. These objectives have been operationalised through a series of strategies, notably the Strategy for the Development of Information Security for the period 2017-2020 and the Strategy for combat against cyber crime 2019-2023. The ITU notes, however, that “while innovative, internet-based e-commerce is expected to bring significant growth and development, obsolete legislation and a lack of harmonisation with EU standards and best practice persist, hampering progress”. As the country becomes increasingly more digitalised, the challenge for Serbian cyber diplomacy will be to develop and enhance avenues of European, regional, and international cooperation.

It's worth noting that while Cuba has participated in international discussions and informal negotiations related to cybersecurity, it has not signed or ratified binding agreements regarding cyberspace or digital rights. Its government has also been criticised by human rights groups for its restrictions on internet access and online freedom of expression, which have limited its ability to fully engage in these discussions.

In accordance with the output produced by the 2013, 2015, and 2021 consensual reports of the United Nations Groups of Governmental Experts on Developments in the Field of Information and Telecommunications in the Context of International Security (UNGGE), Brazil believes that international law enjoys general applicability in cyberspace. For Brazil, this also includes international humanitarian law and international human rights law. Nevertheless, Brazilian delegations have expressed concern that unqualified transfers of international humanitarian law and an unlimited right of self-defence could legitimise cyberspace as a military domain, while also challenging the protective value of sovereignty and cementing a Western-biased status quo.

The country has not assumed a firm stance on the application of international law in cyberspace. Serbia’s position paper concerning the Open-Ended Working Group (OEWG) highlighted that multilateral dialogue on “information security” must occur “with strict respect for the Charter of the United Nations”. Echoing the stance of states such as China, Russia, and Cuba, Serbia also raised the alarm about the “danger of developing offensive ICT and militarising the digital space”.

Cuba has been represented in the United Nations Group of Governmental Experts (UN GGE) on Developments in the Field of Information and Telecommunications in the Context of International Security. It participated in multiple sessions of the UN GGE and has made contributions as part of the NAM (Non-Aligned Movement), a group of countries that are not formally aligned with any major power bloc. As such, a 2017 statement by Cuba emphasised the need to avoid a ‘state militarisation’ of cyberspace and concentrate on peaceful settlement of disputes and conflict prevention. In 2019, for instance, Cuba called for the development of a safe cyberspace environment that can promote well-being, knowledge and human development.

Brazilian diplomats portray Brazil’s role in the often polarised debates on norms of responsible state behaviour as that of a broker or strategic bridge-builder between the different camps rather than a mere ‘swing state’ and highlight that balancing between both camps serves to maintain an independent foreign policy. Brazil sought to focus its chairmanship of UN GGE’s third and fourth iterations on three issues: the role of civilians in cyber conflict, the right to respond, and attribution. Since the 2013 Snowden revelations, the country has been a stark champion of data protection, showcasing exceptional norm entrepreneurship
in relation to cyber-surveillance norms. Brazil has also expressed support for the proposal of adopting a legally binding instrument in the medium to long-term to prevent the militarisation of cyberspace.

Serbia was represented in the 2016-2017 UN Group of Governmental Experts (UNGGE). Despite its EU candidate status, Serbia does not typically vote in alignment with the EU on key cybersecurity resolutions presented before the UN First Committee. Notable examples include UNGA resolution 73/27, which first established the Open-Ended Working Group (OEWG), as well as later resolutions 74/29 and 75/240.

Cuba launched its first strategy on cybersecurity in 2019, emphasising the need for 'cybersecurity and cyber resilience' in the face of potential threats to national security and the economy, as well as protecting critical infrastructure. The resolution also focused on capacity-building and training in cybersecurity and cyber resilience, both within the government and in the private sector.

Brazil’s 2020 National Cybersecurity Strategy (E-Ciber) outlines ten strategic actions to be undertaken in relation to cyber resilience, which include the extension of international cooperation and the enhancement of protection for critical infrastructure. The Strategy pledges Brazil to encourage international cooperation in cybersecurity, participate in joint cyber resilience events and exercises, and expand cybersecurity cooperation agreements. On the level of discourse, Brazil remains committed to international cyber cooperation in resilience, staying true to its traditional stance in favour of multilateral solutions.

Serbia’s legislative framework on cybersecurity is structured upon the 2016 Law on Information Security and its bylaws. The Law ushered in several institutional developments, including the creation of a national CERT in the regulatory agency for electronic communications and postal services (RATEL). The national CERT “monitors the status of incidents on national level, provides early warnings, alerts and announcements, and reacts on incidents by providing the information on affected entities and persons”. [x] It also holds seminars and technical trainings for operators of special importance (critical infrastructure) [x]. 
Meanwhile, the 2021 Cyber Tesla drill (organised in collaboration with the US state of Ohio) constitutes only one example of Serbia’s increased emphasis on critical infrastructure through the prism of cyber defence; the stated objectives included the “construction of military defence system capacities and the National CERT’s capacities for the protection from high-tech attacks, as well as an enhanced cooperation with relevant government and private sector organisations and academic institutions for the purpose of protection of the IT systems”. 
In its UNGGE position paper in 2016, Serbia emphasised the importance of interstate cooperation in “maintaining effective and responsive mechanisms for information exchange, alerts and announcements on cybersecurity incidents”. The paper goes on to posit that “the special focus should be on the protection of critical infrastructure”, especially in the case of transnational attacks. In 2021, Norway donated a platform worth €1.2 million which will “[serve] to hold cyber exercises at the national level enables the real situation of different attack scenarios, and will contribute to capacity building and training of officials in various state institutions”, according to State Secretary of the Ministry of Trade, Tourism and Telecommunications Milos Cvetanovic [x].

Cuba is not a signatory of the Budapest Convention on Cybercrime and has developed its own domestic legal framework in the matter, such as Decree-Law No. 360/2019 which covers a wide range of crimes related to information and communication technologies. In an ongoing debate surrounding this new legislation, critics say that the law could be used to suppress dissent and limit freedom of expression online.

Brazil originally refrained from signing the Budapest Convention on Cybercrime and had expressed scepticism in response to invitations to accede. The argument advanced was that the treaty is Western-biased and lacking in inclusivity, given that Brazil was not part of the original drafting process. During voting for UNGA Resolution A/74/401, the Russian-sponsored proposal for a new binding Cybercrime Convention, Brazil abstained; during meetings with the BRICS leaders, however, Brazil had endorsed Russian pleas for a new cybercrime instrument to replace the Budapest regime. Upon invitation by the Council of Europe, Brazil finally initiated the process of accession to the Convention in December 2019 and is now an observer country.

The Information Society and Information Security Development Strategy for the period 2021-2026 provides a comprehensive approach to the field of information security, which includes both (a) information security of ICT systems of special importance and security of the Republic of Serbia, and (b) security of citizens and businesses, which is particularly reflected through the fight against cybercrime. Its predecessor, the 2017 Strategy for the Development of Information Security, in turn, indicates the fight against cybercrime as one of the government’s five key priorities. 
In light of EU accession negotiations, Serbia has signed and ratified the Council of Europe Convention on Cybercrime (Budapest Convention), including its Additional Protocol on Xenophobia and Racism Committed Through Computer Systems. Nevertheless, the country also voted in favour of UNGA resolution 74/247 calling for an international legal instrument to govern this domain. Domestically, the national legislative framework has been developed in accordance with the Budapest Convention and EU legislation. A High-Tech Crime Unit has recently been established within the special prosecutor’s office, along with three specialised units: crime analysis; terrorism and extremism; and drug prevention, addiction and repression. 
Serbia is a member of Interpol, with which the country has discussed ways to enhance cooperation with regard to combatting cybercrime. Serbia is also gradually developing its own bilateral cooperation network, signing a Cooperation Memoranda with India in 2016 [x] and Romania in 2017 [x] as well as receiving assistance from Russian experts [x].
