Citizens in nations like Venezuela and Russia rely on a proxy for Signal more than ever before. As governments tighten their grip on internet access, encrypted messaging apps such as Signal have gained popularity for their ability to provide secure communication. However, when authorities block these services, users turn to proxy servers to bypass restrictions and maintain their connection to the outside world.
Let’s explore the geopolitical context of Signal censorship, the app’s unique features, and the mechanics of internet control.
The Geopolitical Context of Signal Censorship
Both Russia and Venezuela have implemented policies aimed at controlling internet access and content. According to Ooni, in Russia, more than 247,492 URLs were added to Roskomnadzor’s registry of banned websites in 2022. Many blocking orders targeting independent media and human rights organizations appear aimed at censoring articles or media materials covering events in Ukraine.
In Venezuela, the government has blocked access to websites during politically sensitive times, including the November 2021 regional elections. Private ISPs have been found to block news websites that were previously only blocked by the state-owned internet service provider CANTV. The government has also launched Ven App, a Venezuelan social network and mobile app, which has sparked concerns over its potential to further empower the government to manipulate online discussions.
The geopolitical contexts in Russia and Venezuela have led to increased digital repression, making it challenging for citizens to access uncensored information and communicate freely. This has resulted in a growing reliance on tools like Signal and proxy servers to bypass restrictions and maintain connections to the outside world.

Signal’s Unique Features and Popularity
End-to-end encryption explained
Signal has gained prominence as one of the most secure messaging apps available, primarily due to its robust end-to-end encryption (E2EE) technology. This security feature ensures that only the sender and the intended recipient can access the content of their communications. When a message is sent using Signal, it’s encrypted on the sender’s device and remains encrypted until it reaches the recipient’s device, where it’s finally decrypted.
The significance of E2EE lies in its ability to protect user data from potential interception by third parties, including service providers, hackers, and even government agencies. This level of security has made Signal a preferred choice for privacy-conscious individuals and organizations. Notable endorsements come from reputable news outlets such as The Guardian, The Washington Post, The New York Times, and The Wall Street Journal, all of which recommend Signal for secure communication with their reporters.
Signal’s commitment to privacy extends beyond just message encryption. The app doesn’t store user data, offering additional privacy options such as app-specific locks, blank notification pop-ups, and disappearing messages. This comprehensive approach to data protection has solidified Signal’s reputation as a top tool for identity protection.
User-friendly interface
Despite its advanced security features, Signal has managed to maintain a user-friendly interface that’s familiar to those accustomed to traditional messaging apps. The app’s design includes speech bubble text messages, customizable appearances, and lighthearted features like stories, reaction GIFs, and stickers.
When users open the Signal app, they’re presented with a clean interface displaying a list of their current phone contacts who are also Signal users. This seamless integration with existing contacts makes it easy for new users to transition to the platform. The app provides visual cues to indicate the security status of communications, such as secure connection indicators in the form of a blue send icon with a closed lock image.
Signal offers a range of features that enhance both privacy and user experience:
- Message reaction emojis for quick replies
- View-once media option for photos and videos
- Group chats for staying connected with family and other groups
- Disappearing messages that can be set to vanish after a specified time
- Safety numbers for verifying the security of communications
- Encrypted stickers for adding fun without compromising security
Comparison with other messaging apps
When compared to other popular messaging apps like WhatsApp and Telegram, Signal stands out for its uncompromising approach to privacy. While all three apps offer end-to-end encryption, Signal’s nonprofit status removes any incentive to harvest and sell user data, setting it apart from its competitors.
Signal and WhatsApp both extend their E2EE to voice and video calls, whereas Telegram’s encryption has some limitations in this area. In terms of data collection, Signal collects minimal information, requiring only a phone number for signup. This contrasts with other apps that may collect more extensive user data.
One of Signal’s unique features is its Insights system for Android users, which shows the percentage of encrypted messages sent. This transparency helps users understand the level of security they’re achieving in their communications.
While Signal’s primary focus is on security, it has also made efforts to include social features that users enjoy in other apps. This balance of robust security and user-friendly features has contributed to Signal’s growing popularity, especially following endorsements from high-profile individuals like Elon Musk and Jack Dorsey.

The Mechanics of Internet Censorship
Internet censorship has become a powerful tool for governments to control the flow of information within their borders. This practice takes various forms, ranging from filtering and blocking content to monitoring and penalizing users who access certain information. The mechanics of internet censorship involve a complex interplay of technological, legal, and social factors that governments employ to restrict access to online content.
How governments block apps and websites
Governments utilize several techniques to block access to apps and websites:
- DNS Tampering: Authorities with control over domain name servers can “deregister” a domain hosting content they deem undesirable. This action makes the website invisible to users’ browsers by preventing the translation of domain names to site IP addresses.
- IP Blocking: Governments with control over internet service providers (ISPs) can blacklist certain IP addresses of websites they wish to restrict. When a user attempts to access a blocked site, the ISP drops the connection, causing it to fail.
- Keyword filtering: This method involves scanning the requested Uniform Resource Locator (URL) string for target words. If the URL includes forbidden terms, the connection is reset.
- Packet filtering: One of the newest and most sophisticated censoring technologies, packet filtering examines the actual contents of data packets sent over the internet. If forbidden content is identified, the connection is disrupted.
Different techniques used in Russia and Venezuela
Russia and Venezuela employ various methods to censor online content and control the flow of information:
Russia:
- The country blocks content related to child pornography, drug abuse, suicide, and extremism.
- Roskomnadzor, Russia’s communications regulator, manages a website blocklist containing over 1.2 million URLs.
- The government has implemented laws on military censorship, establishing criminal and administrative liability for criticizing the armed forces or actions of authorities abroad.
Venezuela:
- The Maduro regime has systematically closed traditional media outlets to gain control over accessible content.
- The government has limited consumers’ access to information by shutting down tools like TOR that allow anonymous browsing.
- The country has implemented a national ID card system, “carnet de la patria,” which monitors citizens’ social, political, and economic behavior.

Signal’s Response to Censorship
A Proxy for Signal
In response to censorship efforts by various governments, Signal has taken proactive measures to ensure users can maintain access to their secure messaging platform. One of the key strategies employed by Signal has been the development of proxy servers. These servers act as intermediaries, allowing users to bypass blocks imposed by internet service providers or government authorities.
Signal’s approach involves the use of a simple TLS (Transport Layer Security) proxy, which is designed to circumvent network blocks while securely routing traffic to the Signal service. This proxy system has been implemented for both Android and iOS versions of the app, making it widely accessible to users facing censorship.
The TLS proxy employed by Signal has several advantages over standard HTTP proxies. Connections to the Signal TLS proxy appear indistinguishable from regular encrypted web traffic, making it difficult for censors to identify and block. Additionally, valid TLS certificates are provisioned for every proxy server, further complicating efforts to fingerprint the traffic.
We’re aware of reports that access to Signal has been blocked in some countries. As a reminder, Signal’s built-in censorship circumvention feature might be able to help if your connection is affected: Signal Settings > Privacy > Advanced > Censorship circumvention (on)

The company has also provided detailed instructions on how to connect to a Signal proxy server and manage proxy settings through their Support Center. This information empowers users to take control of their own access to the app, even in restrictive environments.
Furthermore, Signal has encouraged tech-savvy users to set up their own proxy servers to help expand the network of available proxies. The company has provided instructions for this process and has invited those willing and able to contribute to their circumvention efforts.
Balancing security and accessibility
The app’s developers have implemented a system where the Signal client establishes a normal TLS connection with the proxy, and the proxy simply forwards the received bytes to the actual Signal service. This design ensures that non-Signal traffic is blocked, maintaining the integrity of the system.
To further enhance security and privacy, Signal’s proxy system does not require users to provide any personal information that could compromise their identity. This commitment to anonymity makes Signal an attractive option for individuals prioritizing privacy, especially in regions with strict government surveillance.
However, the use of proxy servers may introduce some tradeoffs. As noted by researcher Hossein Derakhshan, the implementation of TLS proxy servers might slow down connections, potentially deterring average users who are accustomed to faster messaging apps and may not be as concerned about surveillance.

Communication Restrictions Effects on Businesses and Innovation
Communication restrictions have significant impacts on businesses, particularly small enterprises. In Venezuela, the ongoing economic crisis has made it challenging for most of the population to afford internet services and devices, as many must prioritize basic necessities such as food and health care. This situation has been exacerbated by the de facto dollarization of the economy, widening the gap between those who have access to US dollars or receive remittances and those who do not.
The cost of internet services has become increasingly unaffordable for most Venezuelans. According to the 2023 Internet Poverty Index, more than 74 percent of Venezuelans could not afford a basic mobile internet package. The prices of electronic devices also remain out of reach for many, with a midrange smartphone costing the equivalent of over 76 months’ pay at minimum wage as of May 2023.
Despite these challenges, small businesses can benefit from using online social networks to observe consumer trends and needs, which can enhance their marketing efforts. Social media adoption by small businesses has been shown to have a positive influence on financial performance and non-financial aspects such as improved customer relations and marketing cost reduction. However, small businesses often lack the knowledge of policies, metrics, and time to utilize social media effectively.

Legal Challenges to Internet Censorship
The legal landscape surrounding internet censorship is complex and varies across jurisdictions. The Communications Decency Act, specifically Section 230, has been instrumental in safeguarding free speech on the internet in the US. This law shields intermediaries from liability for user-generated content, allowing platforms to host diverse speech without fear of legal repercussions. For over 25 years, Section 230 has been instrumental in fostering a free and open internet, protecting small blogs, large platforms, and individual users alike.
In contrast, countries like Venezuela have implemented laws that grant regulatory bodies significant power over online content. The Law on Social Responsibility in Radio, Television, and Electronic Media (Resorte-ME) allows the regulatory body to block or delete content and sanction service providers without due process. Similarly, the Law against Hatred for Peaceful Coexistence and Tolerance requires intermediaries to remove content containing hate speech within six hours or face fines.
Potential court cases against censorship
In the United States, court rulings on Section 230 have protected users and services from lawsuits related to forwarding emails, hosting online reviews, or sharing photos and videos that others find objectionable. These rulings have helped to quickly resolve cases lacking legal basis and have reinforced the principle that individuals should be responsible for their own actions and statements online, rather than the platforms hosting them.
Venezuela’s Law against Hatred has been criticized by special rapporteurs for freedom of expression from the United Nations and the Inter-American Commission on Human Rights for its disproportionate application, which encourages self-censorship. The lack of clear definitions for terms like true information in Venezuelan law leaves room for interpretation and potential abuse.
International legal frameworks for digital rights
International human rights standards provide a framework for addressing internet censorship and protecting digital rights. The right to freedom of expression, peaceful assembly, and association online has been recognized as an extension of existing rights.
However, the implementation of these rights varies globally. Some countries’ constitutions guarantee freedom of opinion and expression, information, and privacy. Others have passed laws that define the limits of these rights’ restrictions under international humanity law.
The challenge remains to balance the protection of free expression with legitimate concerns about harmful content and national security. Internet censorship lawsuits and discussions affect the future of digital rights and online freedoms.
