Vulnerability Intelligence. Patch What Attackers Are Already Exploiting.

Vulnerability intelligence shows which vulnerabilities attackers are really exploiting. You can patch those first, not just rank by CVSS score. Brandefense Threat Intelligence Platform watches underground exploit chatter. It also watches PoC circulation and zero-day signals. It shows which vulnerabilities are being weaponized against your sector right now.

What It Covers

Beyond CVSS: Intelligence-Driven Prioritization.

CVSS scores show paper severity. Brandefense shows which vulnerabilities attackers are discussing, selling and using. That intelligence should drive your patch ranking. The glossary explains these terms: vulnerability intelligence, known exploited vulnerabilities, EPSS and CVE.

  1. 01
    CVE Monitoring

    Steady watching of thousands of CVEs. It tracks NVD publications, vendor advisories, CISA KEV updates and threat intelligence enrichment. The result is a complete, current vulnerability database. It is matched to your tech stack.

    NVDCISA_KEVVENDOR_ADVISORIES

  2. 02
    Underground Exploit Chatter

    Dark web forums, hacking communities and Telegram channels are watched. The watch is for exploit talk. You see when a specific CVE is discussed, tested or offered as a service. This covers threat actors who target your sector.

    DARK_FORUMSTELEGRAMHACKING_BOARDS

  3. 03
    Zero-Day Signal Detection

    Detection of unpatched vulnerability signals. These include references to working exploits for unpatched software. They also include nation-state targeting chatter. A third kind is underground talk of vulnerabilities. Vendors have not yet disclosed or patched them.

  4. 04
    Exploit Marketplace Tracking

    Exploit broker markets and underground trading platforms are tracked. Weaponized exploits are bought and sold there. You see which CVEs have active exploit listings. You also see current prices. You see how many buyers are active. These are signs of demand.

  5. 05
    PoC Circulation Analysis

    Proof-of-concept exploit code is tracked across GitHub, paste sites and exploit-db. It is also tracked on underground sharing channels. A PoC release raises the risk for any company running vulnerable software. So these events are detected.

  6. 06
    Stack-Based Prioritization

    All vulnerability intelligence is filtered and scored against your declared tech stack. Your team gets ranked alerts. They cover only CVEs that are being weaponized. These CVEs must also be present in systems you actually run.

    STACK_MATCHPRIORITY_SCORE

Active. Weaponization Signals.

Brandefense watches exploit chatter, PoC releases and marketplace action all the time. It shows which CVEs are moving from theory to real weaponization. It does so before they are used against your infrastructure.

How It Works

How Does Vulnerability Intelligence Get from CVE Publication to a Prioritized Patch List?

Vulnerability intelligence turns raw CVE data into a ranked action list. The list comes with context. It tells your team exactly what to patch first. This is based on real attacks, not paper scores.

  1. 01Vulnerability Ingestion

    Data flows in all the time. Sources are NVD, vendor security advisories and the CISA KEV catalog.

    More

    They also include security research and proprietary intelligence sources. It captures new CVE disclosures, severity updates and patch status in real time.

  2. 02Underground Signal Monitoring

    Dark web forums, exploit marketplaces, Telegram channels and PoC repositories are watched.

    More

    They are watched in parallel. The watch is for talk about each CVE. This turns raw vulnerability data into intelligence. It shows real attacker interest and skill.

  3. 03Stack Matching

    Every weaponized CVE is checked against your declared tech inventory.

    More

    This covers software, versions, OS, network devices and cloud services. Only CVEs present in your environment raise alerts. So unneeded vulnerabilities add no noise.

  4. 04Exploit Likelihood Scoring

    AI combines CVSS data, underground chatter volume and PoC availability.

    More

    It also weighs exploit marketplace action, actor targeting patterns and sector relevance. The result is an Exploit Likelihood Score. It is one number that tells your team where to focus patching.

  5. 05Alert & Integration

    Priority alerts go to vulnerability management platforms, SIEM, SOAR and ticketing systems.

    More

    Each alert carries full intelligence context and patch guidance. It also carries a weaponization timeline. Analysts lose no time between a signal and the fix.

Coverage

What Does Vulnerability Intelligence. Coverage Include?

No.CapabilityWhat it does
01CVE MonitoringThousands of CVEs are tracked across NVD, vendor advisories and CISA KEV. Updates arrive in real time. They cover new disclosures, severity changes and patch status.
02Exploit Chatter MonitoringReal-time watch of underground forums, Telegram channels and hacking communities. It looks for CVE-specific exploitation talk. It also looks for claims of working exploits.
03Zero-Day DetectionDetection of unpatched vulnerability signals. These are working exploits for undisclosed vulnerabilities. They are also nation-state targeting chatter and talk of unreleased patch bypasses.
04Exploit Marketplace TrackingExploit broker listings are tracked. They show which CVEs are for sale and at what price. They also show how much buyer action there is. This shows demand for weaponization.
05PoC Circulation AnalysisPoC releases are tracked across GitHub, exploit-db and underground sharing channels. A release can raise the risk for vulnerable companies. So these events are flagged.
06Exploit Likelihood ScoringOne composite score per CVE combines CVSS, underground chatter and PoC availability. It also uses market action and sector relevance. It replaces many data sources. You get one ranked action list.
07Stack-Based PrioritizationAll intelligence is filtered against your declared tech stack. Alerts fire only for CVEs present in your environment. This removes unneeded noise. Your patching queue stays clean.
08VM Platform IntegrationIntelligence goes to vulnerability management platforms, SIEM and ticketing systems. Full context, patch guidance and the weaponization timeline arrive in your remediation workflow.
AI Modules

Predictive. Exploit Intelligence.

Four AI modules predict which vulnerabilities will be weaponized. They work before your team runs out of time to patch. They also work before attackers use the vulnerabilities against you.

  • 01 Exploit Likelihood Scoring (ELS)

    A composite scoring model uses 8 signals.

    More

    Three are CVSS score, exploit complexity and underground chatter volume. Three more are PoC availability, market listing activity and actor adoption rate. The last two are sector targeting history and patch adoption lag. It gives one 0-100 likelihood score. This helps teams decide what to patch first.

    ELS_SCORE12_SIGNALS

  • 02 Weaponization Timeline Forecasting

    Time-series models are trained on past CVE exploitation timelines.

    More

    They predict the expected gap between disclosure and mass attacks. Vulnerability management teams get realistic patching deadlines. These come from real attacker behavior, not arbitrary SLAs.

    TIMELINE_FORECASTPATCH_DEADLINE

  • 03 Sector-Based Risk Modeling

    The model links vulnerability exposure with sector targeting patterns.

    More

    It shows which CVEs the threat actors targeting your industry are prioritizing. So your patching matches the actors most likely to target you.

    SECTOR_RISKACTOR_ALIGN

  • 04 Zero-Day Signal Classification

    NLP classifiers trained on underground discussions spot references to unpatched vulnerabilities.

    More

    They tell paper claims from working pre-disclosure exploits. They also tell them from vendor-confirmed zero-days. This surfaces genuine zero-day signals with a clear confidence level.

Questions About Vulnerability Intelligence.

Request a demo
Updated 10 Oct 2026
  • How is vulnerability intelligence different from CVSS?

    CVSS gives a paper severity score. Vulnerability intelligence adds what attackers are discussing, selling and using. So patching follows real attacks, not the score alone.

  • Which sources does it watch?

    NVD, vendor advisories and the CISA KEV catalog. It also watches dark web forums, Telegram channels and exploit markets. It adds proof-of-concept code on GitHub, paste sites and exploit-db.

  • What is stack-based prioritisation?

    Every weaponized CVE is checked against your declared tech inventory. This covers software, versions, operating systems and network devices. Your team is alerted only for flaws that are exploited. They must also be present in your systems.

  • Why does a published proof of concept matter?

    A published proof-of-concept exploit raises the risk for any company running the vulnerable software. So proof-of-concept release events are tracked. They are a warning sign.

  • What is the CISA KEV catalog used for?

    It lists vulnerabilities exploited in the wild. CISA advises companies to use it as an input to their vulnerability management prioritisation. It is a useful signal of what to fix first.

  • What is an exploit likelihood score?

    It is a single 0-100 score that combines several signals. These include CVSS, exploit complexity and underground chatter. They also include proof-of-concept availability, market action and sector targeting history. It shows where patching should start.

  • What is a zero-day signal?

    It is a reference to an unpatched vulnerability. One example is a working exploit. The flaw has not been publicly disclosed or patched. Classifiers separate paper claims from working exploits and vendor-confirmed zero-days.

  • Why track exploit marketplaces?

    Listings show which CVEs have weaponized exploits for sale. They show the price and how much buyer action there is. These act as demand signs. They show how likely a flaw is to be used.

  • How do alerts reach our remediation workflow?

    Priority alerts go to vulnerability management platforms, SIEM, SOAR and ticketing systems. They carry full context, patch guidance and a weaponization timeline.

  • What should we do about an actively exploited vulnerability?

    Find every affected system first. Start with those open to the internet. The How To Defend playbook for actively exploited vulnerabilities covers the first 24 hours. It also covers investigation, containment and hardening.
