(Qihoo 360), a Beijing-headquartered cybersecurity company founded in 2005 that has been listed on China's A-share market since February 2018.

Recent moves7 records

Expansion highlights6 records

Broad incumbents

• Sophos: SMB-focused endpoint security vendor (now within Thoma Bravo's Sophos/Skyhigh group); directly comparable in Business Essential vs Advanced tiered device licensing and centralized management for MSPs.
• Gen Digital (Norton/Avast): Owner of Norton, Avast, AVG and Avira; the largest global consumer security incumbent with overlapping freemium consumer antivirus and SMB endpoint offerings that compete head-to-head with 360 Total Security outside China.
• McAfee: Global consumer and SMB endpoint security incumbent with comparable freemium entry point, premium upgrade tiers, and cross-device pricing that competes with 360 Total Security Premium in international markets.
• Trend Micro: Broad incumbent in endpoint and cloud workload security with consumer, SMB and enterprise offerings; similar vulnerability-research heritage and comparable multi-engine architecture to 360.

Direct peers

• Bitdefender: Direct competitor offering multi-engine consumer and SMB antivirus with strong independent lab detection scores; comparable freemium-to-premium commercial model and similar endpoint security breadth to 360 Total Security.
• Kaspersky: Direct competitor in consumer and SMB endpoint security with comparable engine-based architecture, broad international retail distribution, and similar exposure to geopolitical scrutiny of origin-country vendors.
• ESET: Direct peer in SMB and prosumer antivirus with a freemium-adjacent product line (ESET Smart Security) and similar per-device subscription pricing; comparable freemium-to-B2B upgrade motion.
• Malwarebytes: Direct competitor in endpoint protection (anti-malware, anti-ransomware, browser-level protection) targeting consumers and SMBs, with overlapping browser-extension and Device Protection products analogous to 360's Internet Protection and Document Protector.

Regional players

• Quick Heal: India-based consumer and SMB antivirus vendor with freemium and per-device premium tiers; comparable product architecture and competitive overlap in emerging APAC markets where 360 also distributes.

Others

• CrowdStrike: Next-gen endpoint leader defining the EDR/XDR category that 360 would need to credibly compete with to monetize Yitian Tulong at the enterprise level; not a direct consumer overlap but the strategic reference point for AI-native endpoint detection.
