Top 10 Best Cybersecurity Companies In China 2026

China's cybersecurity market has grown into one of the largest and most self-contained in the world, driven by the Critical Information Infrastructure protection program, the Personal Information Protection Law (PIPL), and a deliberate push to replace foreign security vendors with domestic alternatives. According to IDC China's security market trackers, the country's network security spending has climbed steadily through 2024 and 2025, and the vendors below account for a disproportionate share of that growth. This ranking covers the 10 best cybersecurity companies in China heading into 2026, based on revenue, R&D scale, government certifications, and international recognition.

How We Ranked These

Our selection weighs four factors: disclosed revenue and market position, R&D depth and threat research output, government and enterprise certifications (particularly Ministry of Public Security qualifications), and international recognition from sources including Cybersecurity Ventures and Check Point's Cyber Hub. Because full-year 2026 data isn't final, figures reflect the most recent disclosed numbers from FY2024 and FY2025, with 2026 projections noted where relevant. Companies are ranked by overall market weight rather than any single metric.

The List Of The Top 10 Best Cybersecurity Companies In China 2026:

Qi An Xin is the largest pure-play cybersecurity vendor in China by revenue, reporting approximately RMB 4.3 billion (around US$600 million) annually and holding the #1 spot in the "China's 2025 Top 20 Cybersecurity Companies" ranking. The company was spun out of 360 in 2014 and listed on Shanghai's STAR Market in 2020.

Its government footprint is the widest of any domestic vendor. Qi An Xin served as the official cybersecurity partner for the Beijing Winter Olympics and counts the majority of China's central government ministries and state-owned enterprises as clients. The product line spans endpoint security (Tianqing), situational awareness platforms, and the Pangu security operations platform. It also runs one of the largest threat intelligence networks in the country, which feeds both its commercial products and its national defense work.

2. H3C Technologies (新华三)

Where Qi An Xin leads on pure security revenue, H3C dominates the hardware layer. The company holds more than 35% of China's network security hardware market according to IDC China data from 2024 and 2025, with total ICT revenue exceeding RMB 50 billion across its full portfolio.

H3C is majority-owned by Unisplendour, itself tied to Tsinghua Holdings, which gives it both capital and institutional access. Its SecPath firewall and SecCenter management platforms are deployed across government, finance, and telecom networks. The company's real advantage is integration: security is bundled into enterprise networking deals, giving H3C channel reach that standalone security vendors can't easily match. It has been expanding into AI-driven security operations as of 2025.

3. Venustech (启明星辰)

Founded in 1996, Venustech is one of the oldest security vendors in China and still ranks in the top three domestically by revenue, at roughly RMB 4 billion. Its 2022-2023 stake acquisition by China Mobile reshaped its competitive position.

That China Mobile backing matters more than it might appear. It gives Venustech preferred access to telecom-grade infrastructure security contracts, a segment that's expanding as 5G and edge deployments multiply the attack surface. The company covers intrusion detection and prevention, UTM, SOC platforms, and managed security services. It holds some of the highest-level qualifications issued by China's Ministry of Public Security and is a major supplier to the Critical Information Infrastructure protection program.

4. NSFOCUS (绿盟科技)

NSFOCUS has operated for more than 20 years and remains a fixture in China's top five security vendors. Its anti-DDoS "Cloud Clean" service runs on global scrubbing capacity exceeding 10 Tbps, which puts it among the larger mitigation networks in the world.

The company's NSFOCUS Security Labs produces vulnerability research that Western security teams cite alongside findings from Mandiant and similar firms, an unusual distinction for a Chinese vendor. Clients include telecom carriers, banks, and government agencies, and NSFOCUS maintains operations in the US, Japan, and Europe. Its remote vulnerability scanning and threat intelligence capabilities are widely regarded as the strongest domestically.

5. 360 Security Technology (三六零)

360 is the best-known consumer security brand in China, with over 500 million monthly active users across its free antivirus and browser products. That consumer base funds an enterprise arm, 360 Digital Security Group, that has become a significant government and critical-infrastructure contractor.

The company operates "360 Security Brain," one of the largest threat intelligence and APT-tracking systems globally. It claims to have discovered and disclosed dozens of state-linked APT campaigns, including operations it attributes to Western intelligence agencies, which has made it a prominent voice in China's national cyber defense narrative. 360 is publicly listed on the Shanghai Stock Exchange.

6. Sangfor Technologies (深信服)

Sangfor holds the #1 domestic market share in both VPN and next-generation firewall segments, a position it has maintained across multiple consecutive IDC China reports. Annual revenue sits at approximately RMB 7 billion, making it one of the largest vendors on this list by topline.

Founded in 2000 and listed on the Shenzhen Stock Exchange, Sangfor built its business on the "security plus cloud" convergence model aimed at mid-size and large enterprises. Its NGAF (Next-Generation Application Firewall) and SSL VPN products are the flagship lines. The company has pushed into international markets across Asia-Pacific, where it competes more directly with Western vendors than most of its domestic peers.

7. DBAPPSecurity (安恒信息)

DBAPPSecurity carved out a niche in application, data, and cloud security after its founding in 2007, and its AiLPHA big data security analytics platform is widely deployed across government and financial clients. Revenue is approximately RMB 2 billion, and the company trades on the STAR Market.

Its profile got a national boost from event security work. DBAPPSecurity served as the official cybersecurity partner for the Hangzhou Asian Games in 2022 and 2023, following earlier roles at the G20 Hangzhou Summit. The company is positioned well for China's data security and privacy compliance market, which is expanding rapidly under PIPL enforcement.

8. Topsec (天融信)

Topsec developed China's first commercial firewall in 1996, a year after its 1995 founding, and holds the longest continuous track record in the domestic firewall market. It still ranks in the top three across several firewall segments.

The company was among the first Chinese security firms to achieve EAL3+ certification, a Common Criteria evaluation level that carries weight in government procurement. Its client base skews toward government, military, and large enterprise buyers. In recent years Topsec has pivoted toward industrial internet security and managed security services, leaning on relationships built over nearly three decades of public-sector work.

9. Antiy Labs (安天)

Antiy is the research house of this list. Based in Beijing and Harbin, it maintains one of the world's largest malware sample databases, reportedly exceeding 20 billion samples, and its antivirus engine and threat intelligence are licensed to other vendors and used in national-level monitoring systems.

International researchers have credited Antiy for early documentation of sophisticated APT activity, including contributions connected to investigations like "Operation Shady RAT." Revenue is smaller than the top-tier vendors above, but its influence runs through China's supply-chain security and critical infrastructure endpoint protection programs, where its detection engines often sit inside other companies' products.

10. Asiainfo Security (亚信安全)

Asiainfo Security was formed in 2021 when Asiainfo absorbed Trend Micro's China business, a combination that gave it both domestic telecom relationships and inherited international product engineering. Revenue is approximately RMB 1.5 to 2 billion, and the company is listed on the STAR Market.

The Trend Micro acquisition brought the OfficeScan endpoint security lineage into Chinese ownership, making Asiainfo Security a top-five vendor in China's endpoint security market. Its parent, Asiainfo, is a major telecom software provider, which opens doors at carriers that most security vendors have to work much harder to reach. The company focuses on endpoint, cloud, and 5G security for carriers and large enterprises.
