Some Internet pages warn your that your connection is not private. You can still open these pages - if you are sure they are legitimate.
When click such a link, the following page will load. The question is, do you trust the site? The site has encryption. But the warning means that the site's encryption certificate falls short of public standards for trustworthiness.
In this case, this is one of the security recorders at a CLS site. The certificate is okay. I.S. did not purchase a public certificate for it so it does not have public backing.
(you can skip this paragraph if short on time)
A public certificate is linked to other known, certified public certificates. It would be like taking your car to a national chain for repair. The franchise's manager vouches for the mechanic. The franchise's president vouches for the manager; the regional director vouches for the franchise vice-president, etc. until you reach the final guarantor, the CEO. If you purchase from Amazon or Este or any online retailer, you want their certificate to have that chain of guarantee. The final guarantor, the CEO level certificate, is rigorously approved and guarded, so you can trust any certificate that depends on it. Any online site that uses such a carefully backed certificate you can trust not to have had its Internet encryption cracked.
This site does use a certificate to encrypt communication, BUT it does not have that rigorous guarantee that it has not been hacked, or is not suspect. So the question here is: do you trust the site listed in the green circle below. If you do, click the Advanced button at the bottom.
An additional section of the page will appear. At the bottom there is a link that will load the website that you want. Click that link to finally open the site that you want.
In this example, the encryption certificate came with the security camera recorder. We purchased the recorder from a reputable company. It is highly likely that it has not been compromised. We feel comfortable clicking that link.
