Observed exploitability
Prioritization considers evidence of ongoing exploitation and the statistical probability of exploitation in the short term, above potential impact in isolation.
EXPLOIT & THREAT INTELLIGENCE
Fix what is under active exploitation.
CSURFACE prioritizes every vulnerability by the real probability of exploitation, ahead of the theoretical severity of a static score. The remediation queue stays current as the threat landscape evolves, so the team invests capacity in what matters today.
THE CHALLENGE
Theoretical severity does not tell you what is under attack
Most vulnerability management programs order the remediation queue by technical severity. That score measures the potential impact if the vulnerability were exploited, but it is assigned at disclosure and rarely revised. It does not indicate whether the vulnerability is being exploited now, nor whether exploit code is in circulation.
The result is a miscalibrated queue: the team spends capacity on high-scoring items with no observed exploitation, while medium-severity vulnerabilities — already present in active attacks — remain open. A small fraction of disclosed vulnerabilities concentrates most of the real exploitation, and it is exactly that fraction that needs visibility.
Real exploitation is not the same as yesterday. The EPSS of nearly inert vulnerabilities suddenly spikes, while the CVSS stays put.
EPSS Score — per vulnerability
Stays dormant
Sudden jump
Ordering by theoretical severity misses precisely the vulnerabilities whose EPSS has spiked — many already on the CISA KEV. CSURFACE reorders the queue by real exploitation on the day the landscape changes, not in the next cycle.
A urgência real vive na interseção: as vulnerabilidades que estão ao mesmo tempo na CISA KEV, com exploit público e EPSS alto.
Das milhares divulgadas, poucas caem nas três dimensões ao mesmo tempo — esse núcleo é o que precisa subir na fila primeiro. É exatamente a fração que a severidade teórica dilui.
CAPABILITIES
Prioritization driven by real exploitability
Every vulnerability in your inventory receives a priority that reflects the current threat — and that adjusts on its own when the landscape changes.
Active exploitation catalogs
Vulnerabilities with exploitation confirmed by recognized industry references are automatically elevated in the remediation queue.
Asset context
Each asset's business criticality and degree of exposure enter the calculation — the same vulnerability weighs differently depending on where it is.
Always-current queue
When the threat picture changes, priority is recalculated without manual intervention. The remediation list never falls out of date.
Auditable rationale
Every priority item comes with the reason for its ranking — a clear explanation for the technical team, audit and leadership.
Relevant alerts
When a once-secondary vulnerability becomes critical, the team is notified right away — without flooding the team with noise.
PROPRIETARY SIGNAL
Attacker interest, observed in practice
Beyond public intelligence sources, CSURFACE operates Threat Sensor — open and free — and a mesh of sensors and honeypots that captures real offensive activity: which CVEs, services and patterns attackers are probing right now, at scale.
This attacker interest signal enters as an additional dimension in prioritization. A vulnerability that starts being actively sought on the internet rises in the queue even before it appears in a public catalog — remediation follows the real movement of those who attack.
PRIORITIZATION
Final prioritization weighs many signals
Threat intelligence is one of the factors. Prioritization combines dozens of signals — threat, exposure and business context — in a Machine Learning model, delivering a queue that reflects real risk.
How intelligent prioritization works →HOW IT WORKS
From detected vulnerability to the right queue
01
Assessment
Every vulnerability in the inventory is assessed for technical severity, real exploitability and the criticality of the affected asset.
02
Prioritization
The dimensions are combined into a single priority, accompanied by the rationale that explains why that item ranks above the others.
03
Continuous update
Priority is recalculated whenever the threat landscape changes, and relevant changes trigger an alert to the team.
WHAT YOU GAIN
Capacity invested in the risk that exists now
Prioritizing by the real threat turns an endless list into an objective, defensible remediation plan.
Focus on what matters
The team fixes first what is effectively under threat, instead of following a theoretical order.
Faster response
When a vulnerability enters active exploitation, it rises in the queue and the team is alerted without delay.
Justifiable decisions
Every priority comes with the reasoning behind it — ready for audit and for leadership.
FREQUENTLY ASKED QUESTIONS
FAQ
Does CSURFACE discard technical severity?
No. Technical severity remains an important dimension and enters as the baseline. What changes is that it is no longer the only criterion: the final prioritization combines severity, real exploitability and asset criticality.
How often is the remediation queue updated?
Prioritization is revised continuously. Whenever new evidence of exploitation emerges or an asset's criticality changes, priority is recalculated automatically, with no need for manual intervention.
Is it possible to understand why an item is at the top of the queue?
Yes. Every priority vulnerability comes with a clear rationale for the factors that determined its ranking — suitable both for the technical team and for audit and leadership.
Does prioritization consider asset criticality?
Yes. The same vulnerability receives a different priority depending on the affected asset. Business criticality and degree of exposure enter the calculation, avoiding treating all assets as equal.
