IIS Reviews Summary
Author infoRatingReview Summary
IT System Administrator at Bouri4.0I use IIS for publishing websites with SSL certificates and integrating it with our ERP system and government tax portal. It is user-friendly and integrates well with Windows Server, though certificate performance can occasionally be an issue.
Relationship Manager at a financial services firm with 5,001-10,000 employees3.5I mainly use IIS for our organization's internal Intranet, appreciating its easy setup and simplicity, especially within a Windows environment. However, its limitation to Windows reduces versatility compared to multi-environment servers like Apache.
Information Technology Division Director at Ethiopian Roads Administration4.5My company uses IIS for web applications, deploying them externally post-development. We value its consistent improvements and robust ROI. While it's already beneficial, adding AI features would enhance it further, and its visibility could use refinement.
Information Technology Division Director at Ethiopian Roads Administration4.5We use IIS to deploy applications for internal and external access due to its simplicity and integration with Windows servers. While support from Microsoft can be challenging, our experience helps mitigate issues. Adding monitoring features would enhance its usability.
CEO at WilCom Systems Ltd4.5We use IIS for running web applications, including custom solutions for case management and payment integrations. It's user-friendly, and we've had no security issues. However, frequent user interface changes require server restarts. Cloud deployment provides instant ROI without upfront costs.
Operations Executive at Quess3.0I find IIS simple and easier to manage compared to Linux, although Windows patching is slower and could be improved. I didn't consider other solutions and didn't focus on deployment or ROI in my evaluation.
Testtool expert at Helvetia Versicherungen2.5I primarily use Windows Server for Eggplant Manager, but I am currently dissatisfied with its stability. There are significant issues affecting performance that need addressing, and improvements in this area would enhance my experience with the system.
Senior Cloud Solutions Engineer at Znet Technologies Pvt. Ltd.4.0I use IIS for deploying applications globally, finding it easy to use and understand. However, the solution needs improvements in coding and differentiation between core and technical components to assist developers with limited IIS management knowledge.
