Zero-Day and Vulnerability Monitoring & Response

SenseOn’s Zero-Day and Vulnerability Monitoring service is operated by the 24/7 Managed SOC team to identify, assess, and respond to emerging software vulnerabilities—including zero-day threats and high-impact CVEs likely to be exploited in the wild. This service ensures customers are informed quickly, and where relevant, are supported in identifying exposure and mitigating risk.

A zero-day is a vulnerability that is exploited before it is publicly disclosed or patched. These are often used by advanced threat actors and may not have a CVE identifier yet. Detection and mitigation are difficult due to the lack of documentation or signatures.

The SOC actively monitors and responds to intelligence about suspected zero-days, even if they are not yet formally disclosed.

What Is Zero-Day and Vulnerability Monitoring?

This service combines real-time intelligence monitoring with active threat hunting and customer support to provide a proactive response to newly discovered vulnerabilities.

It covers:

  • Emerging vulnerabilities without assigned CVEs (zero-days)
  • High-severity CVEs that are actively exploited or likely to be exploited
  • Vendor or industry alerts indicating critical security issues
  • Contextual information about exploitability, threat actors, and affected software

The SenseOn SOC reviews, prioritises, and responds to these events, ensuring that affected customers are made aware and provided with guidance.

How It Works

1. Monitoring Intelligence Sources

The SOC monitors a wide range of intelligence feeds for:

  • Zero-day vulnerabilities (unpatched and without CVEs)
  • Critical vulnerabilities disclosed by vendors
  • Exploits observed in the wild
  • Indicators of compromise (IOCs) linked to exploitation

2. Triage and Prioritisation

Vulnerabilities are triaged based on:

  • Risk to data and business operations should successful exploitation occur
  • Exploit availability
  • Targeted software prevalence across customer environments
  • Indicators of active exploitation

4. Threat Hunting and Exposure Assessment

When a vulnerability is confirmed as high-risk:

  • Hunt Lab queries are developed to detect signs of exploitation or exposure
  • Retrospective analysis is run across telemetry (including via Long Term Telemetry Retention, if enabled)
  • Potentially affected endpoints or environments are identified

5. Customer Notification and Assistance

If indicators of exposure are found:

  • The customer is contacted directly by the SOC
  • Remediation guidance and assistance are provided
  • A technical summary or report may be issued depending on impact
