Not sure if you should trust this site?
The CogniView web address is https://www.cogniview.com/
A secure site's web address should begin with https:// not http://. The extra s in https:// stands for “secure”.
You should also see the padlock icon in your browser address bar. In Internet Explorer this should be gold. in Microsoft Edge, it's grey or green.
If you see a lock button next to a website’s address in Microsoft Edge, it means:
- What you send and receive from the website is encrypted, which makes it difficult for anyone else to get this information.
- The website is verified, which means that the company running the site has a certificate proving they own it. Click the lock button to see who owns the site and who verified it.
- While a grey lock means that the website is encrypted and verified, a green lock means that Microsoft Edge considers the website more likely to be authentic. That’s because it’s using an Extended Validation (EV) certificate, which requires a more rigorous identity verification process.
