Zero-Day Response Services

When Zero-Days Hit, Speed Is Everything

A new critical vulnerability is disclosed. BleepingComputer is reporting active exploitation. CISA adds it to the KEV catalog with a 15-day remediation deadline. GitHub has 8 proof-of-concept exploits. Reddit's r/netsec is on fire. Your CISO is asking: "Are we affected?"

This is exactly the scenario CVEPulse is built for. Our CVE Trends Dashboard tracks community signals in real time — you'll see a zero-day trending before it hits your inbox. Our CVE Intelligence Dashboard provides severity scoring, EPSS exploit probability, and PoC availability. And our emergency response services help you move from awareness to action in hours, not days.

What We Deliver

⚡

Rapid Triage

Within hours of disclosure, we assess whether a zero-day affects your environment — checking asset inventory against vulnerable products, versions, and configurations. Clear yes/no/maybe with evidence.

🎯

Impact Assessment

If you're affected, we quantify the blast radius — which systems, which business units, what data is at risk. Mapped to your asset criticality and business context, not just CVSS numbers.

🔧

Remediation Guidance

Patch available? We coordinate emergency deployment. No patch? We deliver compensating controls — WAF rules, network segmentation, configuration hardening, detection signatures.

📢

Stakeholder Communication

Executive-ready briefings for your CISO and leadership team. Technical advisories for your ops teams. Regulatory notification guidance if required. All within the critical first 24–48 hours.

🔍

Threat Intelligence Correlation

Is this zero-day being used by APT groups targeting your sector? Are there IoCs to hunt for? We correlate CVE data with threat actor intelligence to assess whether you're in the crosshairs.

📋

Post-Incident Review

After the emergency: lessons learned, process improvements, playbook updates. Ensure your team responds faster next time. Build institutional muscle memory for zero-day response.

Early Warning Through CVEPulse Dashboards

Our free dashboards are your early warning system. The CVE Trends Dashboard uses a social-signal-first algorithm (v5) tracking BleepingComputer, The Hacker News, Reddit, CISA advisories, and GitHub PoCs. When a zero-day starts trending across multiple sources simultaneously, you'll see it here before formal vendor advisories are published.

The KEV Dashboard tracks every vulnerability CISA confirms as actively exploited — with federal remediation deadlines, ransomware flags, and EPSS scoring. For organizations following CISA BOD 22-01, this is your compliance tracking dashboard.

Frequently Asked Questions

How quickly can CVEPulse respond to a zero-day?

Our dashboards provide real-time awareness — zero-days typically appear on our CVE Trends dashboard within hours of disclosure. For consulting clients, we provide initial triage assessments within 4-8 hours and detailed impact reports within 24 hours.

Do I need to be an existing client to get emergency zero-day support?

Our free dashboards are available to everyone, no login required. For hands-on emergency triage, impact assessment, and remediation guidance, contact us at business@cvepulse.com. We offer both retainer and incident-based engagement models.

How does CVEPulse detect zero-days before official advisories?

Our CVE Trends algorithm tracks 11+ sources including security news RSS feeds, Reddit security communities, GitHub PoC repositories, and CISA advisories. When a vulnerability generates simultaneous signals across multiple sources — journalists writing, researchers posting PoCs, Reddit discussions exploding — our hype scoring surfaces it immediately.

What if there is no patch available for a zero-day?

We provide compensating controls guidance: WAF rules, network segmentation, configuration hardening, detection signatures for your SIEM, and IoC watchlists. The goal is risk reduction until a vendor patch becomes available.
