Machine-Speed Active Defense in the Mythos Era
AI just collapsed the weaponization window from weeks to hours. Here's what that means for your security program, and how to respond.
The Context
A structural shift in cyber risk
On April 14, 2026, the Cloud Security Alliance, the SANS Institute, and over 80 leading CISOs documented how Anthropic's Claude Mythos model autonomously discovered thousands of critical zero-day vulnerabilities, achieving a 72% exploit success rate with no human guidance.
The conclusion: the cost and skill floor for discovering and exploiting vulnerabilities has structurally collapsed, creating a permanent asymmetric advantage for attackers. Every security assumption built on human-paced threat actors is now obsolete.
“The capabilities seen in Mythos will quickly become more widely available, dramatically increasing the number and frequency of complex, novel attacks organizations will face.”
The Problem
Five broken assumptions
The Mythos-ready program challenges every pillar of modern enterprise security.
Patching as the primary control
When time-to-exploit drops below time-to-patch, patching becomes necessary but insufficient. Expect multiple simultaneous high-severity incidents in the same week.
EDR / SIEM as sufficient detection
Signature-based tools generate thousands of false positives and are blind to AI-generated exploits never seen before. SOC teams are overwhelmed before the real threat is spotted.
Annual pentests as validation
“Security posture degrades the moment a pentest report is delivered.” Point-in-time testing creates months of blind spots in a continuously evolving attack landscape.
Manual malware analysis at scale
When AI generates novel exploits in seconds, waiting days for a human reverse engineer creates a critical intelligence gap. Attacker tempo exceeds analyst capacity.
Human-scale SOC operations
Burnout and attrition are now direct operational risks: teams caught between accelerating volumes, expanding surfaces, and the cognitive load of AI integration.
The Solution
Deceive, Detect, Respond
Three integrated products forming a closed-loop defense that operates entirely at machine speed.
Deception & Containment
Beelzebub Cloud
AI-powered runtime deception sensors that produce zero false positives. Only attackers ever touch them. Deploys in under 24 hours with no endpoint agents.
- Zero false positives, 100% verified alerts
- Machine-speed autonomous containment
- Runtime sensors catching AI guardrail bypasses
- A framework adaptable to secure any system
Continuous Red Teaming
Arcangelo
Your autonomous Red Team, running 24/7. Replicates the latest AI-driven attack techniques through continuous adversarial simulation, replacing stale annual pentests.
- 24/7 AI-driven adversarial simulation
- AI model jailbreak testing
- External attack surface mapping (EASM)
- Remediation paths mapped to MITRE ATT&CK
Autonomous Threat Intelligence
Caronte
LLM-powered reverse engineering and sandbox detonation that converts novel exploits into actionable blocklists in minutes, matching AI-generated threat velocity.
- Automated code decompilation
- Safe, isolated payload detonation
- Threat-actor infrastructure mapping
- Automatic MITRE ATT&CK classification
