MindFort research on how frontier AI models and agents perform at offensive security, with NexBench results, model evaluations, and threat analysis.
How Good Is Grok 4.7 For Cybersecurity?
xAI released Grok 4.7 on September 21, 2026 with a bigger base model and a new safeguard stack. On MindFort's NexBench it ranked second of 17 models, but it scored well below Grok 4.6. Here's why.
How Good Is Grok 4.6 For Cybersecurity?
Grok 4.6 is the top-scoring model on MindFort's NexBench, nearly doubling GPT-5.6 Sol's best run for a fraction of the cost. Here's what xAI's cyber evals show, what it refuses, and where it stops short.
How Good Is GLM-5.3 For Cybersecurity?
Z.ai's GLM-5.3 posts the top CyberGym score of any model, but it finished twelfth of 17 on MindFort's NexBench pentest benchmark. Here's why, what it costs, and what its open weights change.
How Good Is GPT-6 Astra For Cybersecurity?
OpenAI released GPT-6 Astra on September 3, 2026, the first model to hit its Critical cybersecurity threshold. But the public version refuses advanced cyber tasks. Here's what that means for security teams.
How Good Is Qwen 3.8 For Cybersecurity?
Qwen 3.8 27B is a small, open-weight model you can run on one GPU, and the uncensored build strips its safeguards entirely. Here's how good it is for real security work, how cheap it is to run, and what a guardrail-free local model changes for defenders.
How Good Is Opus 5 For Cybersecurity?
Anthropic unblocked source-code vulnerability discovery for every Opus 5 user, and the model now finds bugs at close to Mythos-class quality. Here's where it still falls short of Mythos 5, and what defenders should do now.
Introducing NexBench: MindFort's Internal Model Evaluation
Today, we're introducing NexBench, our internal benchmark for measuring which models can lead an offensive-security harness while balancing validated findings, token efficiency, and cost across real-world environments.
Autonomous Attackers Are Here: What the OpenAI / Hugging Face Breach Proves
OpenAI confirmed its own pre-release models breached Hugging Face, finding a zero-day, escaping the sandbox, and reaching production. Here is what the first end-to-end agentic attack means for your security program.
How Good Is Kimi K3 For Cybersecurity?
Kimi K3 is the first open-weight model to reach the cyber frontier, and it does it at a fraction of the cost of the closed labs. Here's how good it is for real security work, how the cost compares, and what an open-weight frontier model changes for defenders.
How Good Are AI Agents For Cybersecurity?
AI agents have topped bug bounty leaderboards, caught real zero-days, and shipped their own patches autonomously. Here's what they can actually do in cybersecurity today, how they stack up against human pen testers, and how to tell a real agent from a scanner.
How Good Is GPT-5.6 for Cybersecurity?
OpenAI previewed GPT-5.6 (Sol, Terra, and Luna) on June 26, 2026, its first model family rated High capability in both cyber and bio. Here's what it can and can't do for security work, how it compares to Mythos, and why it's gated to government-approved partners.
How Good Is Fable 5 For Cybersecurity?
Claude Fable 5 is the most capable model the public can use, but its safeguards quietly route cybersecurity prompts to Opus 4.8. Here's what that means for security work, how it compares to Mythos, and what defenders should do now.
How Good Is Opus 4.8 For Cybersecurity?
Anthropic released Claude Opus 4.8 on May 28, 2026 with the lowest hallucination rate of any tested model. Here's what it's good for in security work, where Mythos still outperforms it, and what defenders should actually do now.
How Good Is Daybreak for Cybersecurity?
Daybreak is OpenAI's most ambitious defensive-AI initiative yet. Here's what it does, where it falls short, and what it means for your security program.
How Good Is Deepsec for Cybersecurity?
Deepsec just launched as an AI security tool. Here's what it gets right, where it falls short, and why runtime testing still matters.
How Good Is Deepsec for Cybersecurity?
Deepsec just launched as an AI security tool. Here's what it gets right, where it falls short, and why runtime testing still matters.
How Good Is GPT-5.5 for Cybersecurity?
OpenAI's GPT-5.5 is the first GPT model classified as High capability for cybersecurity. Here's what the benchmarks, red-team results, and live pen testing data actually say about what it can and cannot do.
Claude Opus 4.7 for Cybersecurity: What It's Good For, What It Isn't
Anthropic shipped Opus 4.7 with intentionally dialed-back offensive capabilities. Here's what it's actually good for in security work, where it falls short of Mythos, and how to defend against Mythos-class discovery without Mythos access.
What Is Claude Mythos? Why Security Teams Need to Act Now
Anthropic's Claude Mythos Preview can autonomously discover and exploit zero-day vulnerabilities at unprecedented scale. Here's what security teams need to know and how to start hardening today.
When AI Hackers Attack: Inside the Claude Botnet That Changed Cybersecurity Forever
Chinese state-sponsored hackers used Anthropic's Claude to autonomously hack 30+ organizations. Here's what this means for defenders, and why you need AI on your side.
