Hi Dylan,
If I am a website owner, what can I do to help minimize the chance of my website being flagged by Microsoft Defender SmartScreen?
There are several things you can do that can help minimize the chance of your site being flagged as suspicious. Think of these as best practices or optimal website design ethics.
If you ask users for personal information, use HTTPS with a valid, unexpired server certificate issued by a trusted certification authority.
Make sure that your webpage doesn't expose any cross-site scripting (XSS) vulnerabilities. Protect your site by using anti-cross-site scripting functions such as those provided by the Microsoft Anti-Cross Site Scripting library.
Use the fully-qualified domain name rather than an IP-literal address. (This means a URL should look like "microsoft.com" and not "207.46.19.30.")
Don't encode or tunnel your URLs unnecessarily. If you don't know what this means, you probably aren't doing it.
If you post external or third-party hosted content, make sure that the content is secure and from a known and trusted source.
