MangaDex safety concerns have been on many readers’ minds since the platform experienced a cyberattack in 2021 that compromised some user information. As an avid manga reader myself, I understand the importance of finding reliable platforms that won’t put our devices or personal data at risk.

Despite these security challenges, MangaDex has significantly improved its protection tools and even launched a bug bounty program that rewards users for identifying potential vulnerabilities. However, the platform recently faced another major setback when hundreds of manga titles were removed, raising questions about its future and legal standing. Furthermore, MangaDex is currently blocked in several countries including Italy, Russia, and Indonesia.

In this comprehensive safety review, I’ll address the question “is mangadex safe?” from multiple angles. We’ll examine both device security and legal considerations, explore user experiences, and provide an honest assessment of whether MangaDex remains a viable option for manga enthusiasts in 2025.

What Does ‘Safe’ Mean When Using MangaDex?

When evaluating if a manga site is trustworthy, we need to consider two distinct aspects of safety that often get conflated. Understanding these differences is crucial before deciding whether MangaDex deserves your trust in 2025.

Device safety vs. legal safety

Device safety refers to protecting your computer, phone, or tablet from security threats. This includes defense against malware, viruses, and phishing attempts that could compromise your personal information or damage your device. Many unofficial manga sites are notorious for intrusive ads, malicious downloads, and security vulnerabilities that put users at risk. In fact, studies show that individuals who download pirated content are 28 times more likely to get their devices infected with malware.

Legal safety, on the other hand, concerns whether accessing content through a particular platform might violate copyright laws or other regulations. While MangaDex itself doesn’t claim to host officially licensed content, the platform does have policies for removing copyrighted material when requested. Nevertheless, users should be aware that reading unlicensed manga translations exists in a legal gray area that varies by country.

Why both matter for manga readers

These safety concerns aren’t merely theoretical—they have real consequences for manga enthusiasts. Following the March 2021 breach that exposed nearly 3 million MangaDex user accounts, the platform had to rebuild its infrastructure after hackers compromised its source code and potentially accessed user databases. MangaDex subsequently warned users to assume their data had been compromised and recommended changing passwords on any accounts sharing the same credentials.

Beyond personal security, legal considerations affect the entire manga ecosystem. Widespread piracy undermines creators’ livelihoods and can lead to fewer official translations being released internationally. Additionally, blocked piracy sites have proven to be effective deterrents for some users seeking unlicensed content.

As a reader, balancing convenience with security often involves trade-offs. While official platforms generally offer better security, they may have limited libraries or higher costs. Essentially, your definition of “safe” depends on your priorities—whether you’re primarily concerned about device security, legal compliance, or both.

How MangaDex Protects Your Device

After experiencing a major security breach in 2021, the MangaDex team has taken concrete steps to enhance platform security. Unlike many alternative manga sites, MangaDex prioritizes user protection through several key measures.

No pop-up ads or fake download buttons

MangaDex stands out primarily by running without intrusive advertising. The site operates through user donations and affiliate programs rather than ad revenue. This funding model eliminates the need for potentially malicious pop-up advertisements or deceptive download buttons that often plague free content sites.

Moreover, the platform’s infrastructure is designed with user safety as a core principle. The team runs applications behind a Web Application Firewall (WAF) using ModSecurity alongside the OWASP foundation’s Core Rule Set to monitor and automatically block suspicious requests.

Use of HTTPS and secure login

MangaDex enforces secure connections by automatically redirecting insecure requests. Any plain-text request is systematically redirected to the secure equivalent URL. This ensures all user interactions with the site remain encrypted.

In 2024, MangaDex implemented a completely new authentication system with enhanced security features, including:

• Two-factor authentication
• Support for physical security keys (like Yubikey)
• Digital passkeys compatibility (Windows Hello, iCloud Passkeys, Google Passkeys)
• Advanced password hashing using PBKDF2 with SHA256 HMAC

Bug bounty and security updates after 2021 hack

Following the March 2021 security breach where hackers gained unauthorized access to administrator accounts and user data, MangaDex undertook significant security improvements. The team patched vulnerable code sections and cleared session data globally to prevent similar exploits.

Consequently, MangaDex established a bug bounty program that rewards users for reporting security vulnerabilities based on their severity. This proactive approach has already shown results—in March 2024, researchers privately reported a security vulnerability that was patched within hours.

To further minimize risk, the platform now employs a defense-in-depth strategy, including:

• Running multiple instances of all applications
• Deploying updates one host at a time to catch issues early
• Ensuring quick rollback capabilities
• Private networks for all infrastructure
• Granular access limitations for internal services

What Users and Experts Say About MangaDex

The online manga community remains divided on MangaDex’s trustworthiness, with review platforms showing mixed feedback. According to Scamadviser, MangaDex has an average score of just 2.4 stars from 29 reviews, though ratings vary significantly across platforms.

Reddit and Quora user reviews

On Reddit, many users praise MangaDex for being ad-free, which they consider a major safety advantage. One concerned user specifically asked, “Is mangadex safe without any ads/potential malware?”, reflecting common anxieties among manga readers.

Quora users often defend the platform, with one noting, “It’s easy to navigate, you can keep track of what series you’re reading, they do a lot of updates to improve their site and it’s safe”. Yet others remain cautious about the platform’s security history, particularly after the 2021 incident where “millions of username and password combos were leaked”.

Comparison with other free manga sites

Among manga platforms, MangaDex stands out with a respectable 4.3/5 star rating according to some sources. Users appreciate its “clean interface” with “minimal ads for a smoother reading experience”.

MangaDex differs from alternatives primarily through its community-driven approach. Unlike sites cluttered with aggressive advertising, MangaDex maintains a sleeker design that many users consider less risky for their devices.

Why MangaDex is considered safer than alternatives

The primary reason users trust MangaDex over competitors is its transparency regarding security issues. After the 2021 breach, administrators “took prompt action and shut down the site before damage could be done”.

Additionally, many recommend MangaDex because it uses fewer aggressive monetization tactics that often lead to security vulnerabilities. As one review states, MangaDex offers a “multi-language support” system with active users who “regularly upload and update new chapters”, creating a more reliable community-monitored environment than many alternatives.

Legal Risks and Country Restrictions

Beyond device security concerns, MangaDex faces significant legal challenges that directly impact its availability and reliability. These legal complexities form an essential part of determining if MangaDex is truly safe for users in 2025.

Fan translations and copyright issues

MangaDex primarily hosts unofficial fan translations (scanlations) of manga, manhwa, and manhua uploaded by users. Despite operating as a non-profit platform, these unauthorized translations remain technically illegal under copyright law. Even unlicensed content distribution violates copyright regulations, regardless of whether the platform displays advertisements.

DMCA takedowns and content removal

Recently, MangaDex experienced its largest takedown in history when over 700 manga series were removed after coordinated DMCA notices from Japanese and Korean publishers, including Kodansha, Square Enix, and Naver. This follows earlier legal actions, such as when Viz Media requested a subpoena against Cloudflare in 2019 to identify MangaDex’s operators over alleged Boruto copyright infringements.

Countries where MangaDex is blocked

Currently, MangaDex is inaccessible in several countries:

• Italy: Blocked since December 2021 by the Italian government agency Autorità per le Garanzie nelle Comunicazioni
• Russia: Access restricted since August 2022
• Indonesia: Blocked by Telkom Indonesia’s ISPs, including Indihome

Using VPNs: risks and considerations

Although many users employ VPNs to bypass geographical restrictions, this approach carries its own risks. VPN software may potentially contain malware, plus users can never be entirely certain how their data is processed by third parties. Additionally, MangaDex’s API documentation notes that VPN users might face reduced request allowances due to sharing network infrastructure with other users.

Conclusion

After examining MangaDex from multiple angles, the answer to “is MangaDex safe?” remains nuanced rather than black and white. The platform certainly deserves credit for its security improvements following the 2021 breach. Their implementation of HTTPS, secure login systems, and the absence of intrusive ads make MangaDex significantly safer for your devices than many alternative manga sites.

Nevertheless, legal concerns persist as a major consideration. The recent removal of hundreds of manga titles demonstrates the platform’s precarious position regarding copyright enforcement. This fact, coupled with country-wide blocks in Italy, Russia, and Indonesia, highlights the uncertain future MangaDex faces despite its popularity.

My assessment ultimately comes down to your personal risk tolerance and priorities. For readers primarily concerned with device security, MangaDex presents fewer risks than ad-heavy alternatives. However, those worried about legal compliance might prefer official platforms despite their limited libraries or subscription costs.

We must also acknowledge that scanlation sites exist in a constantly shifting landscape. Today’s safety measures might not address tomorrow’s threats, while legal boundaries continue to evolve across different jurisdictions. Therefore, regardless of which platform you choose, practicing basic digital hygiene remains essential—use unique passwords, enable two-factor authentication when available, and stay alert to potential security threats.

The manga community thrives because of our shared passion for these stories. Whether you choose MangaDex or official channels, supporting creators whenever possible helps ensure this art form continues to flourish for years to come. Though MangaDex offers convenience and an extensive library, balancing that against ethical considerations ultimately falls to each individual reader.
