Raw CVE data is everywhere. Context isn't.

A CVE (Common Vulnerabilities and Exposures) is a publicly disclosed security flaw with a unique identifier. A KEV (Known Exploited Vulnerability) is a CVE that is confirmed to be actively exploited in real-world attacks, typically tracked by CISA. A zero-day vulnerability is a flaw that attackers exploit before a patch or official fix is available. In vulnerability management, KEVs and zero-days usually require immediate prioritisation because they present the highest operational risk.

CVSS (Common Vulnerability Scoring System) is an industry-standard method for rating vulnerability severity on a scale from 0.0 to 10.0. Security teams use CVSS scores to estimate potential impact, exploitability, and business risk. However, mature vulnerability management programs combine CVSS with threat intelligence, KEV status, exploit activity, asset exposure, and business context to prioritise the vulnerabilities most likely to be exploited.

Use the database to identify actively exploited vulnerabilities, monitor emerging threats, track CVEs affecting your assets, and prioritise remediation based on real-world exploitation risk. Effective vulnerability management combines CVSS, KEV intelligence, exploit prediction, exposure analysis, and asset criticality to reduce alert fatigue and focus remediation efforts where they matter most.

The most critical vulnerabilities in 2026 are typically internet-facing remote code execution (RCE), authentication bypass, VPN, firewall, edge device, and identity platform vulnerabilities that appear in the KEV catalog or show high exploit activity. Attackers continue to target exposed systems with publicly available exploit code, especially vulnerabilities affecting VPN appliances, remote access services, cloud infrastructure, and enterprise identity systems. Threat intelligence and KEV tracking should be monitored continuously because active exploitation trends change rapidly.

Hackerstorm continuously aggregates vulnerability intelligence, CVE feeds, KEV updates, vendor advisories, exploit activity, and cybersecurity news sources to provide near real-time visibility into emerging threats. Vulnerability data, threat intelligence, and exploitation indicators are updated throughout the day to help security teams respond quickly to active risks.

Yes. No fees. No registration. No vendor agenda. Just the data.

Unlike raw vulnerability repositories such as the National Vulnerability Database or CISA KEV catalog, Hackerstorm combines CVE data with contextual threat intelligence, exploit activity, sector-specific risk analysis, security news, and operational prioritisation guidance. The platform focuses on helping organisations understand which vulnerabilities are most likely to impact their environment, not just which vulnerabilities exist.
