- [Introducing Cotool Router](https://www.cotool.ai/blog/introducing-cotool-router.md): Cotool Router gives security teams automatic cross-provider fallback, access to open-weight models, and evaluation-informed model selection for any security task.
- [Agents as Software](https://www.cotool.ai/blog/agents-as-software.md): What does security look like in a world where intelligence is everywhere?
- [Beyond CTFs: Evaluating AI Agents on Real Intrusion Data](https://www.cotool.ai/blog/beyond-ctfs-evaluating-ai-agents-on-real-intrusion-data.md): We benchmarked frontier models on a real macOS infostealer intrusion. This is not a CTF, which tend to test narrow, artificial scenarios. Tasks spanned incident response, threat hunting, and detection engineering.
- [The Security Infrastructure Powering EliseAI's Rapid Scale](https://www.cotool.ai/blog/case-study-eliseai.md): How EliseAI uses Cotool to automate investigations, expand detection coverage, and defend customer data across housing and healthcare
- [Announcing our $7.4m seed fundraising to build the AI Operating system for security teams](https://www.cotool.ai/blog/announcing-our-seed-round.md): Cotool announces $7.4m seed round led by Andreessen Horowitz to build the AI Operating System for security teams
- [Evaluating AI Agents in Security Operations (December 2025)](https://www.cotool.ai/blog/evaluating-gpt-5-1-claude-opus-4-5-and-gemini-3-pro-ai-agents-in.md): Which frontier model should you use for SecOps automation? We added the latest cohort of frontier models to our benchmark to find out.
- [Evaluating AI Agents in Security Operations](https://www.cotool.ai/blog/evaluating-ai-agents-in-security-operations.md): We benchmarked frontier AI models on realistic security operations (SecOps) tasks using Cotool’s agent harness and the Splunk BOTSv3 dataset. GPT-5 achieved the highest accuracy (63%), while Claude Haiku-4.5 completed tasks the fastest with strong accuracy. GPT-5 variants dominated the performance-cost frontier. These results provide practical guidance for model selection in enterprise SecOps automation.
- [Context Management for Agentic Security](https://www.cotool.ai/blog/context-management.md): How we are solving the LLM Security Data problem
- [Security without the Spectacle](https://www.cotool.ai/blog/security-without-the-spectacle.md): Why would anyone want to start an AI security company?
