Anthropic tested Claude Opus 5.5 against 10 CyScenarioBench challenges, with five attempts at each challenge. Without CVP access, every task was blocked at the first prompt. In Defense Access, 46 of 50 trials were blocked at some point and four succeeded. In Red Team Access, no blocks occurred and 34 of 50 tasks were completed. Anthropic says that matched the completion rate when safeguards were not applied. (anthropic.com)
Those figures do not mean a UAE business should remove safeguards. They show that safeguards can be adjusted to the job, and that the adjustment materially changes what a model can do. A sales agent, stock assistant or finance workflow should not receive the same permissions as an authorised security-testing environment.
Anthropic also says partners found at least 129,000 verified software vulnerabilities between April and July 2026. Its own open-source scanning found another 5,500 between April and October. More than 33,000 were rated critical or high severity, although Anthropic says the figures are based on partial data and are likely an undercount. (anthropic.com)
The Register reported a more uncomfortable part of the story: of 5,674 true-positive vulnerabilities cited in Anthropic’s figures, 3,014 were high severity and 1,522 were critical, while only 516 had been patched at the time of reporting. Finding problems faster does not fix them automatically. (theregister.com)
