Nartac Software Inc. is a Canadian publisher that focuses on one narrow but critical area of Windows server administration: the ordering, enabling and disabling of Transport Layer Security cipher suites, protocols and hashing algorithms in Microsoft Internet Information Services. Its two complementary utilities—IIS Crypto GUI and IIS Crypto CLI—wrap Microsoft’s complex registry edits and Group Policy objects into a single-window interface and an equally powerful command-line engine, letting network engineers harden web servers, reverse-proxy farms, RDS gateways or SMTP relays in minutes instead of hours. Administrators typically launch the GUI to run built-in PCI 3.2, NIST 800-52 or FIPS 140-2 templates, visually reorder ciphers, disable legacy SSL 2.0/3.0, enable TLS 1.3, apply forward-secrecy suites and renegotiate settings with one reboot. The CLI sibling then automates the same workflow inside SCCM, Chef, PowerShell DSC or Azure DevOps pipelines, making it easy to propagate consistent TLS baselines across dozens of IIS servers without manual intervention. Both tools export reusable configuration files, create instant rollback snapshots and display comprehensive cipher-suite negotiation tests against Qualys SSL Labs benchmarks, giving auditors visible proof of compliance. Software packaging teams also embed the CLI in Docker Windows containers or golden VM images to ensure every new web instance is crypto-hardened before first boot. All Nartac Software titles are available free of charge on get.nero.com, where downloads are delivered through trusted Windows sources such as winget, always install the latest release and can be queued together for batch deployment.
