ZERODAY CYBERSECURITY
Keep recurring OT security work connected to operational priorities, accountable owners and reviewable evidence. Agree the work and cadence around your operation.
Zeroday helps industrial teams keep agreed OT security work moving after the initial report: review priorities, coordinate actions and owners, examine supporting evidence and record the decisions that remain. The service connects operations, IT/OT and existing technical providers around a defined backlog and review cycle. Activities, cadence and responsibilities are agreed with each client.
This fits an operation with continuing security work, an internal sponsor and technical owners who can participate. It is useful when findings cross teams, provider dependencies delay action or leadership needs a consistent account of what changed and what still requires a decision.
Review the agreed backlog, relevant changes and evidence received since the previous review. Identify changed priorities, incomplete inputs and decisions that need an owner.
Connect actions to implementation owners, provider dependencies and operational constraints. Track agreed next steps and raise blockers through the agreed decision path.
Review submitted records against agreed criteria. Distinguish completed actions, verified conditions, exceptions and unresolved work. Carry the remaining decisions into the next review.
The scope defines review frequency, participating teams, information sources, reporting, coverage arrangements and escalation responsibilities. A scheduled review is a decision point; it does not imply continuous monitoring or an emergency-response commitment.
Where the repeating task is vulnerability applicability, prioritization and treatment, see Managed OT Vulnerability Management. A defined existing backlog can also begin as OT Finding-to-Closure Support.
An agreed service boundary, responsibility map and review cadence.
A maintained register of the included findings, actions and decisions.
Work packages with implementation owners, dependencies and evidence requirements.
A record of relevant changes, completed actions and remaining uncertainty.
Exceptions and unresolved decisions with accountable owners and agreed review points.
A service review showing what needs attention next and why.
Agree the deliverables and acceptance criteria before work begins. The OT engagement buyer guide explains how deliverable acceptance differs from closing a finding or authorizing an operational change.
This fictional example illustrates the record, not a client engagement or achieved result. The agreed scope covers ownership and evidence for a supplier-access finding affecting one production process.
Review 01
Evidence: available records identify the provider but no internal access approver.
Action: the site IT/OT owner agrees the approval responsibility with the provider.
Open decision: what evidence will the authorized reviewer require before changing the finding's status?
Review 02
Change: an internal approver is now named in the example record.
Remaining gap: evidence of the agreed access review has not been supplied.
Next step: the implementation owner supplies the record; the designated reviewer decides whether it meets the criterion. The finding remains unresolved.
An OT Security Assessment defines a review boundary, evidence gaps and priorities. Its findings can inform a proposed ongoing backlog and responsibility map.
We review whether its scope, criteria and evidence are useful for the current decision. Known findings can support a direct ongoing-service discussion; any additional discovery is identified in the proposed scope.
Continuing service requires its own agreement. An assessment remains a useful standalone engagement and does not enroll your organization automatically.
Zeroday leads the agreed review, prioritization, coordination and evidence record. Your sponsor sets operational priorities and acceptance authority. Internal IT/OT owners and providers contribute system knowledge, records and authorized implementation.
Andres Torres leads the executive relationship and program direction. Technical review and specialist work are assigned according to the scope and qualifications required for the environment.
Site and asset complexity, data quality, provider dependencies, review frequency and onboarding effort shape the service. Tools, access, coverage hours and escalation commitments are agreed explicitly. SOC operations, continuous monitoring, incident response and engineering implementation are not implied by the term managed.
For operational context, explore manufacturing, industrial facilities or mining and mineral processing.
Share a nonconfidential summary of the operation, recurring problem, existing findings and people involved. We will discuss the work, decision responsibilities and cadence a useful ongoing scope would require.
