All content about Security, organized for fast scanning.
Recent developments in security technology highlight a growing emphasis on vulnerability detection and management within AI systems. Companies are introducing advanced tools for scanning code and repositories for vulnerabilities, while also enhancing governance and visibility in AI operations. Additionally, regulatory challenges are impacting access to certain AI models, prompting companies to adapt their offerings and security measures to mitigate risks.
Anthropic has just rolled out Claude Mythos 5 in Claude Security, now in public beta for all Claude Enterprise customers. The service scans GitHub repos for vulnerabilities and suggests fixes, but Mythos 5 isn’t exposed for direct use. Pricing is standard token usage.
Anaconda has just rolled out its acquisition of Kilo Code, bringing agent orchestration, a 500+ model gateway, and analytics into its AI development platform. The goal: tighter governance, lower token spend, and clearer visibility across IDEs and providers.
Google DeepMind has just rolled out Gemini 3.5 Flash Cyber, a lightweight model aimed at helping security teams find and fix bugs sooner. The company says it boosts code-path coverage and surfaced Chrome and Android flaws, but results await independent verification.
Anthropic says a US export-control directive forces it to suspend Fable 5 and Mythos 5 access for any foreign national, including its own employees. The shutdown hits all customers, while other Claude models remain available. Anthropic says it’s working to restore access.
OpenAI has just rolled out Lockdown Mode for ChatGPT, limiting web-connected features to reduce prompt-injection risk. It’s also standardizing “Elevated Risk” labels across ChatGPT, Atlas, and Codex to flag network-exposed capabilities.
Anthropic has just rolled out Defending Code Reference Harness, an open-source reference for using Claude to find and fix vulnerabilities. It includes guided Claude Code skills plus a sandboxed C/C++ pipeline with ASAN and gVisor, though the repo is unmaintained.
Anthropic has rolled out a new security-guidance plugin for Claude Code, designed to flag risky patterns during edits, model turns, and commits. The company says internal testing cut security-related PR comments by 30–40%, while users debate accuracy and false positives.
OpenAI’s latest post explains how it’s deploying Codex with tighter sandboxing, approval gates, and policy controls to reduce risky actions. It also highlights deep logging via OpenTelemetry so teams can audit prompts, tools, and network activity.
OpenAI has just rolled out GPT-5.5-Cyber, bringing a new “frontier cybersecurity model” to critical cyber defenders. Early reactions focus on trusted access, benchmarks, and whether controls can prevent misuse by attackers.
Claude has just rolled out Claude Security in public beta for Enterprise customers, promising vulnerability scans with validated findings and patch suggestions—no API integration required. New additions include scheduled scans, exports, webhooks, and scan-to-scan dismissals.
Cursor has just rolled out Cursor Security Review, bringing always-on code review and scheduled scanning to Teams and Enterprise. It includes a PR-focused Security Reviewer and a Vulnerability Scanner that can post findings to Slack, with customizable triggers and tooling.
With the launch of GPT-5.4-Cyber, OpenAI is rolling out a more cyber-permissive model for vetted defenders. The company is also scaling Trusted Access for Cyber to thousands of verified individuals and hundreds of teams protecting critical software.
Anthropic’s preview-only Mythos impressed the UK’s AI Security Institute, completing a 32-step network takeover simulation other models couldn’t. The takeaway: outcomes scale with token budget, pushing security toward a compute-and-cash contest.
Anthropic has launched Project Glasswing, a cross-industry effort using the unreleased Claude Mythos Preview to find and help patch serious vulnerabilities across major OSes, browsers, and key software. Partners include Apple, AWS, Google, Microsoft, and more.
