Zero-day & emerging threats

Catch what has no signature yet

A novel exploit rarely has a rule the day it drops. VultSight defends in layers — by behaviour, by intelligence, and by hunting — so a zero-day is caught by what it does, not just what it's called.

The problem

Signatures always
arrive late

A zero-day is, by definition, something no one has written a rule for yet. Waiting for a vendor signature or a patch means waiting while the attacker is already inside. The only reliable early signal is behaviour — because even a brand-new exploit still has to dump credentials, move laterally and call home.

  • Not a scanner or patcher — VultSight detects and contains exploitation, and complements your vulnerability-management tools
  • Signature-independent — behavioural and statistical detection fire with zero prior knowledge of the exploit
  • Intel-accelerated — the instant an indicator is public, it's matched in real time and hunted retroactively

Defence in depth

Four layers, no single point of failure

If a zero-day slips past one layer, the next one catches it. Together they turn an unknown exploit into a contained, documented incident.

🧠

1 · Behaviour, not signatures

UEBA baselines and MITRE ATT&CK technique detection flag the actions an exploit takes — credential dumping, lateral movement, C2 beaconing — even with no known indicator.

🌐

2 · Intel the moment it lands

CISA KEV, Sigma and OSINT feeds sync continuously and new IOCs match in real time. Analysts can submit an indicator manually for instant coverage the moment a CVE breaks.

🔭

3 · Retroactive hunting

When a new exploit or IOC surfaces, sweep historical events to answer "were we already hit?" — before it becomes an incident.

🎯

4 · Prioritise & contain

Ingest Tenable and Qualys scan results to rank alerts by vulnerable, actively-exploited and business-critical assets — then contain automatically via SOAR.

Timeline

How a zero-day plays out in VultSight

From disclosure to containment — the same workflow whether the threat is known or brand new.

📢

CVE disclosed

A new vulnerability or exploit goes public — often before any vendor signature exists.

🔄

Intel syncs

CISA KEV, Sigma and OSINT feeds pull the new indicators; analysts can add IOCs manually for instant coverage.

Detect in two ways

Real-time IOC matching fires on the indicator; behavioural detection fires on the exploit's activity — whichever comes first.

🎯

Prioritise

Correlate with Tenable/Qualys scan data to focus on assets that are both exposed and business-critical.

⚙️

Contain

SOAR playbooks isolate endpoints, block C2 and revoke access in seconds, with approval gates where needed.

🔭

Hunt the past

Sweep historical events for the new indicator to confirm whether the exploit was already used — and close the loop.

Frameworks & standards

Built on the standards your team already speaks

Detection, data and compliance all map to recognised frameworks — so VultSight fits your reporting, not the other way around.

Detection natively speaks MITRE ATT&CK, Sigma, STIX/TAXII and CVE/KEV. The compliance module maps your controls to the frameworks you report against — with evidence drawn from the platform's tamper-evident audit trail. We don't claim certifications you don't have; specific documentation is shared under agreement.

FAQ

Questions security teams ask

Does VultSight patch zero-day vulnerabilities?

No — VultSight is not a patch-management tool. It detects and contains the exploitation of vulnerabilities, including zero-days, and ingests vulnerability-scan data to prioritise exposed assets. It complements, rather than replaces, your patching and vulnerability-management programme.

How does it detect a zero-day with no signature?

By behaviour. UEBA baselines and MITRE ATT&CK technique detection flag the actions an exploit takes — credential access, lateral movement, C2 beaconing — even when no indicator of compromise exists yet.

How fast do new indicators take effect?

Threat-intel feeds (CISA KEV, Sigma, OSINT) sync continuously and new IOCs match in real time. Analysts can also submit an indicator manually for instant coverage the moment a CVE is disclosed.

Which vulnerability scanners integrate?

Tenable and Qualys scan results are ingested so alerts can be prioritised by assets that are both exposed and business-critical.
