Vietnam Signals Major Expansion of National “Cybersecurity Firewall” Under New Draft Law

Vietnam is preparing to significantly expand state control over its digital infrastructure, with a newly published draft revealing plans to build a centralized national “cybersecurity firewall” system.

According to reporting by The Vietnamese, in its article “New Draft Reveals the Ministry of Public Security’s Expanding Cybersecurity Firewall”, the Ministry of Public Security (MPS) has introduced a sweeping legal framework that would formalize deep network monitoring, encrypted traffic inspection, and expanded enforcement authority over online content.

The draft follows the passage of Vietnam’s new Cybersecurity Law (2025), set to take effect on July 1, 2026, consolidating earlier digital governance regulations. But what stands out in this latest development is the explicit use of the term “national firewall system” – language that had not previously appeared in Vietnamese legislation.

What the Draft Proposes

The proposed technical standard, titled “National Technical Standard on Cybersecurity – Firewall – Basic Technical Requirements,” outlines a mandatory infrastructure with capabilities that go far beyond conventional enterprise firewalls.

Key technical features include:

• Deep Packet Inspection (DPI) to analyze internet traffic content.
• SSL/TLS inspection, enabling authorities to decrypt, review, and re-encrypt encrypted web communications.
• Integration of user identity data into control policies.
• Blacklists of at least 100,000 domain names.
• Mandatory logging of detailed user session data, including timestamps, source/destination IPs, protocols, and responses.
• Automated risk scoring for user activity.

Additionally, telecommunications providers would be required to:

• Store subscriber-linked IP identification data for at least 12 months.
• Provide user data within 24 hours, or three hours in urgent cases.
• Establish direct technical connections to the MPS’s cybersecurity force.
• Store all collected data domestically at the Ministry’s National Data Center.

The scale of these measures represents a significant centralization of digital oversight.

Beyond Monitoring: Expanded Enforcement Powers

Separate draft decrees would expand police authority to investigate and adjudicate so-called “fake news” and harmful online content.

Under the proposal:

• The MPS could independently initiate investigations.
• Broad definitions of “fake news” would apply.
• Investigators may collect evidence and seize materials in certain cases without prior judicial authorization.

This signals a transition from passive monitoring to active digital enforcement.

Global Implications

Vietnam has long been regarded as maintaining strict internet governance. However, the formalization of a national firewall system – combined with deep inspection and centralized data storage – places it among countries pursuing highly controlled digital ecosystems.

From a cybersecurity perspective, several broader implications emerge:

1. Increased compliance burdens for multinational companies operating in Vietnam.
2. Heightened complexity for global cloud providers.
3. New risks around cross-border data governance.
4. Elevated concerns over encryption integrity and data sovereignty.
5. Expanded regulatory exposure for telecom and platform operators.

As enterprises navigate tightening digital regulations worldwide, this development reflects a growing global trend: states asserting greater control over cyberspace.

What Organizations Should Do Now – 10 Recommended Actions

For enterprises operating in Vietnam or in similarly regulated environments, security and compliance teams should:

1. Conduct a regulatory impact assessment on new cybersecurity laws.
2. Review data localization strategies and storage architecture.
3. Reassess encryption practices in light of potential SSL/TLS inspection mandates.
4. Strengthen zero-trust network architecture to protect sensitive assets.
5. Implement enhanced log integrity and monitoring controls.
6. Evaluate vendor and ISP contracts for compliance obligations.
7. Update incident response plans to address rapid data disclosure requirements.
8. Conduct privacy impact assessments under evolving regulations.
9. Provide continuous cybersecurity awareness and regulatory training through trusted providers such as Saintynet Cybersecurity.
10. Monitor geopolitical and legal developments affecting cross-border digital operations.

Organizations seeking strategic advisory and compliance support may benefit from working with Saintynet Cybersecurity to align technical safeguards with evolving legal frameworks.

Balancing Security and Digital Rights

The Vietnamese government has stated that publishing drafts during holiday periods complies with procedural law. However, observers have raised concerns about consultation timelines and transparency.

At the same time, Vietnam faces a reported shortage of approximately 700,000 cybersecurity personnel, even as regulatory ambitions expand.

This raises a broader question: how can governments balance national security, digital sovereignty, operational capacity, and individual privacy?

The answer will likely shape not just Vietnam’s digital landscape, but also regional cybersecurity governance models across Asia.

Why This Matters Beyond Vietnam

For MEA policymakers, telecom operators, and enterprise CISOs, Vietnam’s approach highlights a key global shift: cybersecurity law is increasingly intersecting with surveillance architecture, data sovereignty, and digital identity controls.

Governments worldwide are redefining what “cybersecurity” means – not only in terms of protection against cybercrime, but in managing information flows, online speech, and infrastructure oversight.

Whether similar frameworks emerge elsewhere remains to be seen, but the trend toward centralized digital governance is unmistakable.

Conclusion

Vietnam’s proposed national cybersecurity firewall marks a pivotal development in state-led digital regulation.

By combining deep packet inspection, encrypted traffic review, centralized logging, and expanded investigatory authority, the draft law signals a significant expansion of centralized digital oversight.

For organizations operating in regulated digital environments, this development underscores the importance of aligning cybersecurity architecture with evolving legal requirements, without compromising operational resilience or privacy safeguards.

CyberCory will continue monitoring this evolving story and provide updates as the draft advances through consultation and legislative review.
