First thing to check is if the suspected website is using Secure Socket Layer (SSL) encryption to communicate or not.
This usually means that the website is using a "trusted SSL certificate" which is not given until the website is a known, vetted and trusted corporate entity (which most scam or exploit sites would not have). Sites using an SSL certificate will typically have HTTPS:// in their website name.
Modern day browsers will typically display a "View site information" symbol before the website name (***.com). This (when pressed) will reveal if a Website to Browser connection is "secure" (using SSL encryption) and also, if the SSL certificate being used for this encryption is "valid".
The SSL certificate description will provide information on which Certification entity verified and issued the certificate, who it was issued to (the current website whose name must match) and (most importantly) - if the SSL certificate has expired or is going to expire (and on what date). Browsers will typically block communication to sites with expired certificates. Hopefully - the people who maintain the websites will renew the certificates long before they expire.
Also - if there are other issues with known malware-exploit websites, they will typically be blocked with a warning by most modern browsers (which makes the case for updating browsers to the latest version). Additionally one can install various browser checking plugins (for Edge, Chrome, Duckduckgo, Firefox and Opera) which provide an additional layer of protection. Most reputed well-known anti-malware companies have these plugins available.
