Integration at a glance
| Item | Detail |
|---|---|
| Partner products | Nozomi Networks Platform: Guardian sensors and Central Management Console (CMC) |
| Integration method | DeRISK reads data from CMC or directly from Guardian through the Nozomi Networks API. Read-only. The API connection needs no manual effort and keeps the data current for analysis. Manual import of API JSON output files is also supported, so the OT environment never needs a standing connection to DeRISK in the cloud. |
| Data used | Asset inventory, vulnerabilities, network zones, communication links |
| Built and supported by | DeNexus |
| Certification | Certified by Nozomi Networks |
| DeRISK grades supported | Level 4 · Evidence-Grade (facility data) and Level 5 · Engineering-Grade (zone data), as each grade becomes available |
The challenge
The Nozomi Networks Platform gives OT and security teams a live view of what is on the network and what is exposed. Leaders still need a number they can budget against. A list of vulnerabilities and anomalies does not say what the business stands to lose.
How it works
Guardian sensors passively monitor OT traffic. CMC brings data from many sites into one console.
DeRISK CRQ reads that data on a schedule through the Nozomi Networks API. Only changes are pulled after the first load.
DeRISK combines it with threat intelligence and each facility’s business data.
DeRISK simulates how likely (frequency) and how severe (magnitude) cyber incidents could be, and reports the results in dollars.
What you get together
Risk in financial terms.
Expected annual loss and loss at higher confidence levels, by facility and company.
Vulnerabilities ranked by dollar impact.
Fix the ones that drive the most loss.
Projects compared before you spend.
Test mitigation options and see the risk reduction of each.
Requirements
- The Nozomi Networks Platform: Guardian, with or without CMC
- A read-only Nozomi Networks API account for DeRISK
- For automatic collection, a network path from DeRISK to CMC and/or Guardian (not needed for manual JSON import)
- A DeRISK CRQ subscription at Evidence-Grade or Engineering-Grade, as each grade becomes available
Proof
A leading European energy company, 16 facilities across 3 regions.
With the Nozomi Networks Platform and DeRISK CRQ v5, it found that 5 facilities carried 56% of total expected annual loss. Its top mitigation project, business continuity and disaster recovery planning, cut the highest-risk facility’s expected loss by ~58%.
A leading European transmission system operator, 3 substations.
In a 9-week assessment, a $60K backup and recovery project reduced Value at Risk more than a $150K remote-access project. The highest-impact project was not the most expensive.
