Release Notes
2.12.0.0.x Major Release (TBD - EOL: TBD + 24 months)
What’s New in this Release
NFO Security Update
This security update includes the following:
Feature Highlight: Zero-Touch SNMP Automation
Ditch the manual configuration. Get instant visibility.
This release introduces the Zero-Touch Discovery Engine, turning hours of setup into seconds of automated discovery. Simply define your network ranges—NFO does the rest.
The Power of Automation:
- Instant Inventory: Watch your device list populate in real-time as NFO probes your subnets.
- Smart Classification: NFO automatically recognizes the difference between a core switch, a firewall, and a wireless controller, applying surgical-grade polling the moment they’re found.
- Self-Healing Dashboards: If your hardware changes, NFO auto-updates your metrics and groups. Your visibility stays current, even when your network doesn't.
This release includes:
- Improved Device Classification: Automated device classification via a new Device Type field to accurately categorize hardware like routers, firewalls, and switches across major vendors. You can now customize this identification logic through enhanced GUI mapping tabs or YAML-based rule sets for granular infrastructure visibility.
Customer Request/Ticket numbers: NFC-12181
- SNMP Polling Rules: We've added a powerful new feature that allows you to create custom rules for filtering SNMP polling data. You can now define conditions using logical and comparison operators to report on only the most critical interfaces or devices, significantly reducing the load in large-scale environments.
Customer Request/Ticket numbers: NFC-11995
- Improved Auto-discovery: When credentials are not specified for a subnet, devices will be polled using all configured credentials.
Customer Request/Ticket numbers: NFC-12079
- Added SNMP sysObjectID to Default OIDs: The default SNMP polling OIDs now include sysObjectID, providing enhanced device identification and compatibility.
Customer Request/Ticket numbers: NFC-11996
Implement NFO Central feature (Preview)
NFO Central utilizes a custom, dynamic load balancing algorithm to distribute incoming traffic. The system continuously monitors real-time data, such as flow rate by exporter, to determine the least loaded NFO peer and automatically rebalance traffic distribution. This rebalancing is also triggered instantly when nodes join or leave the cluster.
Customer Request/Ticket numbers: NFC-12131
Improved Device NetFlow Statistics
The system now collects and displays Input Packets (Total and Rate) per device under the Status -> Statistics -> Devices screen. This new, granular metric provides deeper visibility into network flow activity and is a foundational step for implementing rate-based load balancing
Customer Request/Ticket numbers: NFC-12122
Added support for AES-256C in SNMPv3
This release introduces support for AES-256C encryption, providing "military-grade" security for sensitive telemetry. This specific symmetric cipher implementation leverages 256-bit keys with Cipher Feedback (CFB) mode to deliver enhanced privacy and data protection for SNMPv3 communication. It is specifically designed for compatibility with high-security Cisco and OpenSSL-based systems.
Customer Request/Ticket numbers: NFC-12174
Improved MDT Input Configuration
Enhanced validation for MDT input settings and watch lists, including checks for MDT TLS configuration ID uniqueness, valid certificate/key file access, and correct network interface address/port settings.
Customer Request/Ticket numbers: NFC-12134
Splunk HEC output: added channel identifier
Added a channel identifier for Splunk HEC outputs, now with support for indexer acknowledgment.
Customer Request/Ticket numbers: NFC-11915
Unified HEC Output for Splunk and CrowdStrike Falcon LogScale
NFO has expanded its HTTP Event Collector (HEC) output capabilities to provide seamless, native support for both Splunk and CrowdStrike Falcon LogScale. This update allows organizations to utilize a single, high-performance ingestion protocol for their preferred analytics and SIEM platforms.
Customer Request/Ticket numbers: NFC-12208
Enhanced NFO stability
Improved Quality of Service (QoS) mechanisms to prevent out-of-memory (OOM) situations and ensure more stable performance under heavy load.
Customer Request/Ticket numbers: NFC-12105
2.11.3.0.49 Maintenance Release (July 31, 2025 - EOL: July 31, 2027)

Customer Request/Ticket numbers: NFC-11922, NFC-12008
Improved Auto-discovery feature
We have significantly enhanced our Auto-discovery feature to include an automatic and rule-based device classification system. Previously, the feature could discover devices and their basic properties. Now, it can also automatically classify them, allowing you to create and manage device groups more efficiently. This new functionality streamlines the onboarding of new devices and ensures consistent policy application across your network.
Key Features:
- Automatic Device Classification: Auto-discovery now automatically assigns devices to a default group based on SNMP SysObjectID and other identifying attributes.
- Rule-Based Device Grouping: Create your own custom rules to automatically classify and assign discovered devices to specific groups based on criteria you define. This allows for tailored configurations and reporting for different segments of your network.
- Enhanced Usability: This improvement reduces manual effort and simplifies the management of large-scale network environments.
