Security | Threat Detection | Cyberattacks | DevSecOps | Compliance

It was a bold move, but our finance team was fully on board. They both approved and championed the approach. They wanted to see exactly how much value we could unlock for our customers. They didn't look at the resulting bill and ask us to slow down.

RAG systems connect AI models to your internal data, making them powerful but also creating serious security gaps in access control, data retrieval, and compliance. Knowing how to ensure data security in RAG systems means securing every layer of the pipeline from ingestion to retrieval to output.

The question circling boardrooms and compliance departments in 2026 is no longer hypothetical: Can AI replace a QSA? After nearly two decades guiding organizations through PCI DSS audits, gap assessments, and remediation programs, the answer is clear — No, AI cannot replace a Qualified Security Assessor in 2026. But it is fundamentally reshaping what being a QSA means, and professionals who ignore that shift do so at their own peril.

Anthropic’s Project Glasswing and the Claude Mythos model represents a fundamental change in the physics of cyber defense. With the gap between patch releases and weaponized exploits shrinking to hours, traditional manual security triage is now obsolete. Organizations must adopt AI-driven automated remediation.

→ Audit your AI systems against EU AI Act requirements now — validate Annex IV technical documentation, logging, and data governance. The initial August 2025 compliance date has passed, and full penalties begin in August 2026. → Build a continuous compliance evidence chain — document risk management across the full lifecycle (design, development, deployment, and post-market monitoring).

What began as reports about Anthropic’s Mythos model has now moved into a gated research preview called Mythos Preview. For cybersecurity, that immediately raises an important question: what happens when advanced AI can accelerate offensive workflows such as vulnerability analysis, exploit development, and attack planning? In a recent Cato blog post, we addressed the broader strategic shift this represents.

Generative AI creates new attack surfaces that traditional security tools were not designed to address. The biggest generative AI security risks include prompt injection, data leakage, shadow AI, compliance exposure, model poisoning, insecure RAG pipelines, and broken access control. Each one requires a specific defense, not a generic firewall or DLP rule.

Employees move sensitive data into AI tools every day. Someone pastes customer records into ChatGPT to draft an email. A developer feeds proprietary source code into a coding assistant to fix a bug. A project manager drops a confidential contract into Gemini to summarize it for a meeting. According to research from Cyberhaven Labs, 39.7% of the data employees share with AI tools is sensitive, and enterprise adoption of endpoint-based AI agents grew 276% in the past year alone.
