Optimization of network device hardening in a multivendor environment.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
This paper presents a Python-based Nornir framework for automating network device hardening in multi-vendor environments, addressing critical gaps in scalability and interoperability. Unlike existing single-vendor solutions, our method enforces CIS benchmarks across Cisco, Juniper, and Fortinet devices, achieving an 82.18% reduction in hardening time compared to prior automation tools and a 99.99% improvement over manual techniques. By leveraging Nornir's multi-threading and vendor-agnostic inventory management, the framework ensures consistent security policies while eliminating configuration errors. Experimental results across 18 heterogeneous devices demonstrate its efficiency, with full hardening completed in 44 s (95% CI [43.8, 44.1]). This work provides enterprises with a scalable solution to rapidly secure complex networks against evolving threats, bridging the gap between compliance standards and real-world deployment.
