Running an ongoing vulnerability programme with Tenable
Scanning needs a routine for coverage, triage, remediation and verification. Here is a practical cadence to adapt to your systems and responsibilities.

An ongoing vulnerability programme keeps the asset inventory, findings and remediation work connected. Scanning is one input. The programme also needs owners who can decide what to fix and evidence that the changes worked.
Use the following cadence as a starting point, and agree timing and responsibilities for your environment.
Check collection and urgent findings regularly
Confirm that scanners, agents and connectors are reporting successfully. Watch for failed authentication and assets that have disappeared from collection. Falling finding counts may indicate missing coverage rather than improvement.
Review new findings against known exploitation, reachability and business impact. Urgent issues need an escalation route between scheduled meetings. Define who can restrict access or authorise an emergency change when waiting would leave a serious exposure.
Put actions where the owners work
A remediation ticket should identify the affected asset, evidence, proposed action, owner and target date. Where one update addresses many findings, group the work without losing traceability.
Tenable Vulnerability Management provides centralised findings and prioritisation. Confirm the ticketing integration available in your setup; the existence of an API does not guarantee a ready-made workflow for every service desk.
When patching must wait, document the reason, interim protection and review date. Risk acceptance belongs to an authorised business owner and should be proportionate to the consequence.
Review coverage and results monthly
Revisit business-service mappings, new systems and changes in ownership. Examine overdue high-priority work and recurring findings. A repeatedly reopened issue may need a deployment fix rather than another ticket.
Report both remediation and coverage. Useful measures include the share of intended assets successfully assessed, age of important open findings, time to verified remediation and exceptions past their review date. Averages alone can hide a small number of long-running exposures.
Give management decisions to make
A periodic management review should explain material changes, unresolved risks and the resources or approvals needed. Attach enough evidence for important conclusions without asking management to read the entire scan output.
Keep assessment scope, policies, decisions and verification records organised throughout the year. They support assurance work, but no particular report length or meeting schedule automatically satisfies a standard.
The first-assessment guide covers the initial baseline. FM’s exposure management service can support the ongoing work, with the division between assessment, remediation and risk acceptance set out in the engagement.
