Is GLM (Z.ai) suitable for cybersecurity?

Not specifically. GLM (Z.ai) is not on our list for cybersecurity; it is broadly applicable, but first look at the options we recommend for cybersecurity. Always keep a professional in the loop.

May I put confidential data into GLM (Z.ai)?

A security tool sees everything: log files, emails, usernames and network traffic. That is personal data, so you need a data processing agreement and must know where the data is stored. Also ask whether the AI assistant will be trained on your data. WithSecure (Finland) says it processes data for Luminen in AWS in Europe and does not train foundation models on customer data. Sekoia stores data in Germany or elsewhere in the EU/EEA and is ISO 27001 certified. SoSafe (France) can run self-hosted. With Microsoft Security Copilot, you choose the geo of your workspace, but sharing data with Microsoft is switched on by default. For Charlotte AI, ESET LiveAI and Mindgard, the hosting location is not publicly stated. Never let an agent intervene in production systems without analyst approval, and record who makes the 24-hour notification under the Cybersecurity Act in the event of an incident. The international service Z.ai runs through JINGSHENG HENGXING TECHNOLOGY PTE. LTD. (Singapore); personal data is in principle processed in Singapore. According to the data processing agreement, API content is processed in real time and not stored. GLM-5.2 is open-weight under MIT and can therefore be fully self-hosted or hosted via an EU provider.

How much does GLM (Z.ai) cost?

There is Z.ai Chat (Free), GLM Coding Plan Lite ($18 / month), API — GLM-5.3 ($1.40 / $4.40 per 1M). Check current prices on the official site.

GLM (Z.ai) raises a concrete GDPR concern. Parent company Zhipu (Beijing) falls under Chinese data and security law, regardless of where the servers are located. For sensitive data, self-hosting the MIT-licensed weights is the recommended mitigation. Weigh this heavily before using it in cybersecurity.

Confidentiality and GDPR

GDPR: Caution

A security tool sees everything: log files, emails, usernames and network traffic. That is personal data, so you need a data processing agreement and must know where the data is stored. Also ask whether the AI assistant is trained on your data. WithSecure (Finland) says it processes data for Luminen in AWS in Europe and does not train foundation models on customer data. Sekoia stores data in Germany or elsewhere in the EU/EEA and is ISO 27001 certified. SoSafe (France) can run self-hosted. With Microsoft Security Copilot you choose the geo of your workspace, but sharing data with Microsoft is on by default. For Charlotte AI, ESET LiveAI and Mindgard the hosting location is not public. Never let an agent act on production systems without analyst approval, and record who makes the 24-hour report under the Cybersecurity Act when an incident occurs.

The international service Z.ai runs through JINGSHENG HENGXING TECHNOLOGY PTE. LTD. (Singapore); personal data is in principle processed in Singapore. According to the data processing agreement, API content is processed in real time and not stored. GLM-5.2 is open-weight under MIT and can therefore be fully self-hosted or hosted through an EU provider.

Rule of thumb Use the business variant with a data processing agreement, and keep a human in the loop for decisions that matter.
