Angry IP Scanner vs Lansweeper

Angry IP Scanner is a free, open-source desktop tool for scanning IP addresses and ports. It accepts address ranges, random addresses, or files in any format as scan input. The scanner checks whether hosts respond to pings and can optionally resolve hostnames, identify MAC addresses, and scan ports. It also supports NetBIOS information, favorite IP ranges, web server detection, and customizable openers. Java plugins can extend scanning and data gathering with fetchers, pingers, exporters, and feeders. Results can be saved as CSV, TXT, XML, or IP-Port list files, and a command-line interface is available. It runs on Linux, macOS, and Windows under GPLv2. The maker says installation is unnecessary and that the software can be copied and used anywhere. It is described as particularly useful to network administrators monitoring and managing networks. The FAQ notes that some antivirus vendors have flagged the older ipscan.exe, while saying version 3.x is not detected.

Lansweeper is Cyber Asset Intelligence software for organizations seeking visibility into their technology environments. It discovers IT, operational technology, cloud, and virtual assets, including unmanaged and rogue assets. Discovery can be agentless, with an IT Agent available for situations such as work-from-home environments. Inventory tools include data federation, normalization, classification, cleanup rules, dashboards, and generated diagrams. Lansweeper also provides vulnerability insights and flags software or assets that are at or approaching end of life. The platform offers a GraphQL API, webhooks, marketplace integrations, and a Flow Builder for custom workflows. Starter limits integrations to Service Desk ticket enrichment and has limited API features; Pro and Enterprise include marketplace apps, while full API access is in Enterprise. Lansweeper offers cloud-first Lansweeper Sites and on-premise Lansweeper Classic. Its cloud service uses TLS in transit, AES-256 at rest, encrypted credential storage, and logical customer-data separation. The free plan covers up to 100 assets. A 14-day trial provides access to all features without a credit card. Starter costs $199 a month billed annually; Pro costs $379 a month billed annually.
