Qihoo 360 vs Baidu Security: A Head-to-Head Durability Check

Chinese cybersecurity is a crowded field, and two of its most visible names sit in very different structural positions. Qihoo 360 runs as its own listed business with its own products and its own profit and loss. Baidu Security exists as a capability inside Baidu's AI Cloud, with no standalone financial reporting. This comparison, one of 412 head-to-head comparisons generated from the 10,525-company WillItSurvive dataset assessed in July 2026, works through what that structural difference means dimension by dimension.

A note on method before the numbers. We never declare an outcome for any company. Forward-looking material appears only as dated watch-items you can verify yourself.

The standings

Of the 10,525 companies assessed in July 2026, Qihoo 360 carries a standing of "Losing its protection" while Baidu Security carries "Protection under test." Neither label is comfortable, but the comparison's headline finding is that Qihoo 360 holds the stronger position on every one of the five dimensions examined. The core reason is identity: Qihoo runs as its own profitable business with a real moat, while Baidu Security has no separate financial identity and can be copied more easily by rivals.

Core product staying power

Qihoo 360 operates a dedicated antivirus and AI security product line, giving it a track record independent of any parent company. Baidu Security, by contrast, has no separate profit and loss statement. It exists as a feature inside Baidu AI Cloud, so its standing rises and falls entirely with that cloud unit's fortunes. In the July 2026 assessment, this dimension went to Qihoo.

That dependency matters in practice. If Baidu reprioritizes its cloud spending, the security capability moves with it, whether the security business itself is healthy or not. Qihoo's fate is at least its own to shape.

Exposure to general AI

Both companies work in a field that large language models are pressing on, but the two look different on this front. Qihoo's tools are only partly folded into general AI capability, because vulnerability hunting still requires specialized signatures and domain expertise. Baidu Security looks more likely to be absorbed by general AI, since its functions overlap heavily with what large language models can already automate. Again, edge to Qihoo.

Moat: how easily a giant copies them

Qihoo's tools are rated meaningfully harder for a large rival to replicate than Baidu Security's. A giant could copy Qihoo's tools, but it would still need to build distribution and trust with state and enterprise clients, which takes years. Baidu Security already sits inside a giant's cloud platform, and other giants such as Alibaba or Huawei could replicate its offering feature for feature.

Competitive pressure

Baidu Security faces heavier competitive pressure than Qihoo 360, contending simultaneously with Qihoo 360, Alibaba Cloud Security, Tencent Security, and Huawei. Qihoo's competition is narrower, mainly Qi An Xin and Knownsec contesting similar contracts. Both firms face real rivalry, which is consistent with both carrying cautious standing labels, but Baidu Security's rival set includes every major Chinese cloud player at once.

Financial footing

Qihoo 360 posted a net profit of RMB 263 million in FY2025, reversing a RMB 1.09 billion net loss the year before, on revenue growth of 9.37%, per the July 2026 assessment. That is a real swing, though a single profitable year is not yet a trend, which is why the next earnings cycle appears in the watch-items below.

Baidu Security has no comparable numbers of its own. Baidu's AI Cloud infrastructure subscription revenue grew 143% year over year, per the July 2026 assessment, but that figure covers the whole cloud unit, not security specifically, and Baidu took a company-wide RMB 16.2 billion impairment charge in the same period. The absence of unit-level reporting is itself a finding: readers cannot verify whether the security business is growing, shrinking, or subsidized.

Questions this data answers

Is Qihoo 360 or Baidu Security better positioned for the AI era? Qihoo 360 is better positioned in the July 2026 assessment because it operates as its own profitable company with a clearer moat, while Baidu Security has no standalone financial results and a weaker moat. Baidu Security's fate is tied to whatever happens to Baidu's broader AI Cloud business.

Which company has a bigger moat? Qihoo 360's tools are rated somewhat harder for a giant to copy quickly than Baidu Security's, which are seen as likely to be replicated feature for feature by rivals such as Alibaba or Huawei.

Does Baidu Security report its own revenue? No. Baidu Security has no separate profit and loss statement. The only available figures cover Baidu's broader AI Cloud infrastructure and applications revenue, not the security unit specifically.

Is Qihoo 360 profitable right now? Yes, as of the July 2026 assessment. Qihoo 360 reported RMB 263 million in FY2025 net profit, reversing a RMB 1.09 billion loss the prior year, with revenue up 9.37%.

Who faces more competitive pressure? Baidu Security does, contending with Qihoo 360, Alibaba Cloud Security, Tencent Security, and Huawei all at once. Qihoo 360's rivalry is narrower, mainly Qi An Xin and Knownsec.

What to watch

Three dated watch-items from the July 2026 assessment, all verifiable by the reader:

1. Baidu breaking out separate revenue for its Security unit. This would show whether Baidu Security can stand on its own outside the AI Cloud numbers it is currently folded into.
2. Qihoo 360's next full earnings cycle. This would confirm whether the return to profit is a lasting shift or a one-time result.
3. A rival such as Alibaba or Huawei launching a security tool matching Baidu's offering. This would show how quickly Baidu Security's already thin moat erodes further.

The comparison swept all five dimensions to Qihoo 360, but both standings, "Losing its protection" and "Protection under test," signal real uncertainty. The gap between them is structural rather than a verdict on either firm's future.
