What should I watch out for with AI in cybersecurity?

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.

Latest developments

9 November 2026Claude Code stores approved commands containing passwords in settings.local.json

If you choose "Yes, and don't ask again" in Claude Code, the tool saves the command verbatim in .claude/settings.local.json, including passwords or API keys. Apiiro found real secrets in 1,122 of 104,185 public copies on GitHub, including 379 database passwords. Keep the file out of git, use variables for secrets, and replace any keys that have already leaked. source

November 2 2026Message threads (beta) fall outside Zero Data Retention

With message threads in the Claude API, Anthropic stores the conversation, the system prompt and the tools on the server, encrypted in memory and not on disk, until up to one hour after the last use. The feature does not qualify for Zero Data Retention; your other ZDR agreements still apply. If you work with personal data under ZDR, only enable threads if your DPIA covers it. source

26 October 2026Swedish government office blocks the browser version on work computers

From 26 October, the Swedish government office blocks ChatGPT and Claude on work computers because there is no formal contract and there are information security risks; Microsoft Copilot remains permitted. Business use therefore requires a contract with data processing terms. source
