Tenable — exposure management, implemented and operated by Passeca

Not 40,000 CVEs, but the twelve that are reachable and exploitable. Exposure management on Tenable, prioritised by real risk and integrated with PassIRP and PassAI-Guard.

Request a Tenable demoSee exposure management

Tenable is an exposure-management platform that prioritises vulnerabilities by real risk — reachability, asset criticality and active exploitation — rather than dumping every CVE. Passeca implements, tunes and operates Tenable, driving remediation of the exposures that matter and feeding the highest-priority ones into PassIRP and PassAI-Guard so they are treated as live security risk, not backlog.

The product

What does Tenable do?

Prioritisation, not just detection.

A scanner tells you there are 40,000 CVEs in your environment. Tenable's exposure-management approach (Tenable One) tells you which twelve actually matter — the ones on internet-reachable, business-critical assets, being exploited in the wild. It combines vulnerability data (from Nessus), asset context, threat intelligence and reachability analysis into a prioritised view.

This is the shift from vulnerability management (a list) to exposure management (a prioritised plan). For security teams drowning in scan output, it is the difference between working from a backlog and working from a risk.

The partnership

What Passeca adds

Implementation, tuning, remediation driving, and integration with PassIRP and PassAI-Guard.

Tenable prioritises, but remediation is still a human and organisational challenge. Passeca configures the prioritisation to the business context, then drives remediation with the right teams — IT, platform, cloud — tracking it to closure. High-priority exposures flow into PassIRP, correlated with active detections so an exposure being exploited becomes an incident immediately.

Audience

Who is Tenable + Passeca for?

Estates where vulnerability volume has outpaced the team's ability to prioritise.

  • Large or distributed estates drowning in scan output.
  • NIS2 and DORA-scoped entities needing risk-based vulnerability handling.
  • Organisations that want 'fix these twelve' rather than 'here are 40,000 CVEs.'

FAQ

Tenable and Passeca, answered

The questions security leaders ask when moving from vulnerability to exposure management.

What is Tenable?
Tenable is an exposure-management platform (Tenable One). It combines vulnerability data with asset criticality, threat intelligence and reachability context to prioritise the exposures that are actually exploitable — not the long tail of theoretical CVEs.
How is exposure management different from vulnerability management?
Vulnerability management lists every CVE — often tens of thousands. Exposure management prioritises: it weights each vulnerability by whether the asset is reachable from the internet, how critical it is, and whether it is being actively exploited. The output is 'fix these twelve' rather than 'here are 40,000 CVEs.'
What does Passeca add to Tenable?
Implementation, tuning, remediation prioritisation, and integration with PassIRP and PassAI-Guard. Passeca configures Tenable for the estate, tunes the prioritisation to the business context, drives remediation with the right teams, and feeds high-priority exposures into the incident workflow.
How does Tenable integrate with Passeca platforms?
High-priority exposures from Tenable flow into PassIRP, where they are correlated with active detections — so an exposure that an attacker is actively exploiting becomes an incident, not a backlog item. PassAI-Guard can triage and prioritise accordingly.
Who is Tenable + Passeca for?
Organisations overwhelmed by vulnerability volume that need to prioritise by real risk rather than CVSS alone. It pairs with Passeca's vulnerability-management service and is the exposure layer inside managed security programmes for large estates.
Does Tenable replace vulnerability scanning?
No — it builds on it. Tenable includes vulnerability scanning (Nessus) but layers exposure context on top: reachability, asset criticality, and threat intel. The result is prioritisation, not just detection.
How does exposure management fit NIS2 and DORA?
Both frameworks require risk-based handling of vulnerabilities and exposures, not blanket remediation. Exposure management on Tenable produces the prioritised, risk-based evidence these regulations expect — fix what matters, document why.
How do I buy Tenable through Passeca?
Request a demo through /contact/demo. Passeca scopes the estate, configures Tenable, tunes the exposure prioritisation, and offers ongoing managed operation of the exposure-management programme.
