Usage policies that prohibit using AI to violate citizens' rights, and support for governments writing those protections into law.
Preparing for the 2026 US midterms
Earlier this year, we shared an update on our election safeguards. Here, we outline how we’ve continued to strengthen these safeguards ahead of this year’s US midterms.
Strengthening our defenses against distillation attacks
Illicit distillation allows model developers to copy frontier AI capabilities without creating proportionally robust safeguards. Here, we describe how we’ve reduced the rate of distillation by more than 90%.
2026 Usage Policy update
We’re publishing a new version of our Usage Policy. In this post, we summarize the changes we’ve made.
Introducing the Life Sciences Verification Program
The Life Sciences Verification Program (LSVP) gives life science professionals access to Claude Mythos, Opus, and Sonnet models with a refined set of safeguards more permissive for biology-related work.
Detecting and countering misuse of AI: September 2026
Over the past eight months, our Threat Intelligence team identified and disrupted operations in which threat actors tried to use Claude for malicious activity. In this report, we share case studies from those operations and describe how malicious use of Claude has evolved since our previous threat reports in 2025.
Developing Enterprise Frontier Safeguards with our customers
We’re announcing Enterprise Frontier Safeguards (EFS), a solution that combines the privacy of zero data retention with state-of-the-art safeguards for detecting misuse. EFS works by storing data in cloud infrastructure controlled by the customer, not Anthropic.
How Claude’s text watermark works
In this article, we share answers to some of the questions we’ve received about how our chosen watermarking method works, whether it affects Claude’s outputs, and why we’re making this change.
An off switch for dual-use knowledge in AI models
New results on a method of controlling access to potentially dangerous AI capabilities
What we learned mapping a year’s worth of AI-enabled cyber threats
As AI changes how cyberattacks happen, how well do the security community's frameworks hold up? A new report maps attacks onto MITRE ATT&CK.
Mapping AI-enabled cyber threats: Insights from the LLM ATT&CK Navigator
We’ve spent the past year investigating how threat actors are weaponizing AI to conduct cyber operations. Today, we’re sharing a new analysis that maps these real-world attacks onto the MITRE ATT&CK framework.

Detecting and preventing distillation attacks
We have identified industrial-scale campaigns by three AI laboratories—DeepSeek, Moonshot, and MiniMax—to illicitly extract Claude’s capabilities to improve their own models.
Updating restrictions of sales to unsupported regions
To account for this reality and better align with our commitment to ensuring that transformative AI capabilities advance democratic interests, we are strengthening our regional restrictions.
Detecting and countering misuse of AI: August 2025
We’ve developed safeguards to prevent the misuse of our models, but malicious actors are actively attempting to find ways around them. Today, we’re releasing a report that details how.
