The Threat Landscape Just Changed

Anthropic's Claude Mythos Preview just changed the math on vulnerability risk. It autonomously discovered thousands of zero-days across every major OS and browser, and weaponized known CVEs in under a day, at under $2,000, with no human in the loop. That capability will be in attacker hands within 6 to 12 months.

The volume is rising. The window is shrinking. And the attacks are now machine-speed.

Manual workflows were already falling behind. Keeping pace with this AI-accelerated threat landscape requires a fundamentally different operating model.

Automation is the Way Forward

The old model is simple: scan on a schedule, produce a list, triage manually, hand off to IT, wait for a patch. Each step is owned by a different team. Each team is working from a different tool. Each tool is seeing a different slice of the environment. Each handoff is creating gaps that widen the exposure window.

The post-Mythos era demands something different. Continuous detection before vulnerabilities are formally named. Exploitability assessment grounded in your actual risk context, not a CVSS score. Automated triage and response that doesn't wait for a human to start the clock.

Introducing the Zero Day Agent

Imagine starting every day knowing that your environment is scanned for newly disclosed vulnerabilities, assessed and validated in your unique environment, with fixes to the vulnerabilities that actually matter waiting in the ticket queue for the right person.

The Zafran's Zero Day Agent makes that the new normal. It runs continuously across your existing stack, answering the question every team asks when a new zero day drops: Am I exposed? Zero Day Agent detects exploitability within 24 hours of disclosure and automatically routes response to the right people minutes after detection.


Here's what it does.

Find Newly Disclosed Zero Day Vulnerabilities, Every Day

The Zero Day Agent runs daily against your environment, scanning public sources, threat intelligence feeds including CISA KEV, MITRE ATT&CK, EPSS, and custom sources to surface newly disclosed zero-days before they're formally enumerated in the CVE pipeline.

That timing matters. By the time a vulnerability receives a CVE, attackers may already have a working exploit. The Zero Day Agent starts the clock earlier, giving your team a head start while others are still waiting on scanner updates.

Instantly Know if Your Environment Is Exposed

Not every newly disclosed vulnerability is a real risk in your environment. The Zero Day Agent assesses whether you're actually exposed, in real-time.

It starts by cross-referencing newly discovered vulnerabilities against your SBOM to identify which components are present in your environment. From there, it maps each finding against your unique risk context: runtime presence, internet reachability, active threat intelligence, and the configuration of your existing defenses.

This analysis gives you a clear answer to the question every security team asks when a high-profile zero day drops. Are we actually exposed?

Autonomously Remediate & Mitigate in Minutes

If the Zero Day Agent determines you're exposed, the response starts immediately. Work Item Policies instantly create tickets, assign ownership, and set SLAs without waiting for a human to decide who handles it. Tickets route directly through your existing ITSM tools, Jira or ServiceNow, pre-populated with the affected asset, the vulnerability details, the exploitability context, and the recommended next steps. By the time your team sees the ticket, the work is already organized and in the right hands.

Since patches aren’t available immediately, the Zero Day Agent doesn’t wait for one. Instead it includes detailed mitigation steps that use your existing controls (EDR, firewall policies, WAF rules) so risk reduction starts immediately, not when the patch is ready. When a patch does become available, Zero Day Agent surfaces the remediation details and routes them to the right owner through the same workflow.

Using compensating controls to neutralize a vulnerability closes the exposure window and gets the most out of the tools you've already invested in. A patch you don't have yet can't protect you. Your existing controls can.

Scale Beyond the Zero Day Agent With Autonomous Workflows

The Zero Day Agent answers a specific problem: how do you respond to newly disclosed vulnerabilities at machine speed. But the deeper challenge facing VM teams isn't any single threat. It's keeping an entire exposure management lifecycle moving at the pace the threat landscape now demands.

Autonomous Workflows are Zafran's answer to that challenge. Complex, multi-step work like detecting exposures, validating exploitability, routing tickets, deploying mitigations, running remediation scripts, and generating reports now happens automatically, with built-in approval flows that keep the right people in the loop before anything executes.

Autonomous Workflows use AI Agents to execute multi-step investigations, generate context-aware reports, and take action across your entire security stack. Simultaneously, Work Item Policies ensure immediate accountability by auto-creating tickets, assigning to the right person, and setting SLAs the moment a vulnerability is detected. Autonomous Workflows eliminate silos, speed up processes, and provide a centralized platform for scalable, repeatable VM playbooks.

AI-Driven Defense for an AI-Accelerated Threat Landscape

Autonomous Workflows takes Zafran's Exposure Management up a notch. Security teams get a solution that scales to match the volume of an AI-accelerated threat landscape, with faster time to respond to the vulnerabilities that actually matter. Not through more headcount, but through automation that runs continuously across the stack your team already owns.

The gap between disclosure and exploitation is measured in hours. The gap between exploitation and response doesn't have to be. The Zero Day Agent and Autonomous Workflows are available now.

A Practical Guide: Evolving from VM to CTEM

Traditional vulnerability management must change. So many are drowning in detections, and still lack insights. The time-to-exploit window sits at 5 days. Implementing a Continuous Threat Exposure Management (CTEM) program is the path forward. Moving from vulnerability management to CTEM doesn't have to be complicated. This guide outlines steps you can take to begin, continue, or refine your CTEM journey.
